If anyone is interested in observing the oil in differential while running further, I recommend you check out Gale Banks videos on differential oiling using different diff. covers. He shows how switching to a modified differential cover can change how it gets oiled good or bad
This is easily one of the most informative videos I've seen on the effect of lubrication. Very well done, all of you! I'd love to see a similar style video on a gearbox - not for the oil lubrication, but to see a gearbox in action.
@@DonDon45-i5h ....I would assume it depends on where the differential is. If it's located next to the gearbox, as in modern front wheel drive cars, which is right next to the engine, inside the warm engine bay, it picks up heat from the engine too, (apart from the internal heat), and it deffinately gets up to temperature. You may need to drive it for a while, to warm up, but eventualy it reaches some temperature. It may or may NOT be the "opeating" temp, but it will get warm enough to flow nicely as it is designed. Or at least flow as we see it in room temperature. If the diff is away from the gearbox, like the one in the video, I have my doubts. It is very well cooled all the way around, and you may need to run it for longer, or maybe with load, to warm it up enough to reach the flow of room temperature.
The spec for the amount of gear oil was wrong. The plug level is correct. If you dont get the level to that height the inboard and outboard axle bearings are not recieving any lubrication. The level should always be just above the bottom of the axle tubes. Regardless of the axle.
Yeah the capacity of the diff was increased as the vacuum formed cover was made over the exterior of the original, yet the screw holes were in the same location. Only adds a millimetre or two here and there but it all adds up when it comes to volume.
The repair book volume is for draining through a plug and changing which leaves some residual behind. They definitely should have filled it all the way.
I was wondering why they didn't vacuum form the inside of the differential pan. Probably harder to get all the air out on the inside then it was on the outside.
Vacuum forming the inside probably would have done the opposite; made the volume smaller slightly and raising the oil level too high. Ultimately unless you took a mould of the original and then cast a clear replacement from the mould, it’s always going to be slightly different. Easiest fix would have been to just follow the general rule and fill it to the plug regardless of how much you have to put in.
Drill some holes in the housing on the other side and epoxy in some lights to backlight the gears. And a polarized lens cap will eliminate some of the glare off the cover.
Wouldn't that make it easier? Visibility of pulling in straight, but maneuverability of reversing in. As long as you can make that connection in your head
Gale Banks did this on his RUclips page sometime back, except the cold show. Oil never really freezes, but it does get very, very, very, thick at extreme cold. As thick as it reguarly is when warm it adheres well enough to the stuff when not moving to lubricate it for a while when operating cold. Look at how much is on the sides of the housing when the cover was off. It will warm up shortly when operating and continue doing its job. Following what Banks showed about aftermarket covers, I took mine off and fabricated a channel of aluminum sheet metal to direct the lube directly onto the ring gear and the side splash onto the spiders. The hardest part of that process was deciding where to put the mounting holes for the channel into the diff cover. I used 2 stainless steel studs in the cover and attached the channel with nuts and lock washers using spacers to locate it close to the ring gear. Thanks for the video that was nice.
Well over ten years ago there were polycarbonate diff covers available for dana 30, 44, and 60 (which also fits 70) axles. They discontinued as far as I know from a lack of interest. But they were 1/2" or 3/4" thick polycarbonate and claimed to be bullet proof. They were available in Jeeping/4x4 catalogs back in the day.
The cover is shaped so that the oil is like a hose to the front pinion bearing, that's why those big square diff covers are junk, they just make a big foaming mess and stop oil flow to front pinion.
The plug fill/drain on the differential housing is located at the height you must not fill above or the fluid will flow out the axles and mess up those greased bearings and the brakes. So the fill amount is actually about 1.5 quarts / 1.4 liters at the plug hole maximum. Banks did a video of the development process and had clear caps of different after-market designs and is worth watching.
Suggestion: what happens when using different lubrication on manual gearbox? Or at rear-end? ATF?, cooking oil?, Hydralic Oil 32S (very common at my work place)
Well, don't put 80w-90 oil if it requires some gear specific lubricant that most modern vehicles use, more of a 0(5)w-30,40 weight, unless you want to change a lot gear box components
@@pliedtka I've put 80w90 in the crankcase as a topup (and to stem the thinned oil from leaking everywhere) in the dead of winter to get the beater to the spring - I'm not changing oil at -20 temps lol. Did that for 3-4 years, engine lasted all the way till the end (Rust got the car).
@@pliedtka Please consider that 75/80/90 weight gearbox oil is a different viscosity 'scale' than 0/5/10/.. weight for engine oil. Thats due to different ISO-norms applying.
@@Crazystuffyousee what u were talking about? If u just search "banks power rear diff cover" there is 3 separate video with transparent diff cover were made by by banks
Great and entertaining video. The world is getting to know Vlad and his carefree happy-go-lucky personality. May I suggest making a see through water pump, I understand that they cavitate at high speed and stop pumping.
I have a rear end tail, or tale. I had a 99 Rodeo and the pinon leaked and the right wheel bearing leaked too. I had not been checking the level but found out it was very low. It was cold, cold for here one morning, about +15 to 20 deg F and after driving for about 5 miles the rear end started howling and guess what oil was in it was sticking to the case starving the gears. The closest place was Walmart about 4 miles away. Pulled in there and they filled the diff but it stilled howled about the same. Got a rear end from the salvage for $250 and installed it by my self in a day. No more leaks and the rear end was quite. For me it turned out OK and learned a lesson.
The reason the amount of oil was lower is that you've cast the cover on the outside of the real one. So the internal volume increased by the volume the walls of the metal cover would have taken up.
Who else noticed that left wheel is out of round? Y'all guys are the best car channel on you tube. This is also the reason I always warmed my diff and tranny up before I raced. Needs to be properly warmed up to provide proper lubrication. Even in warm weather. Edit due to punct.
we had a farm tractor back in the 50s ( dad told me of this) it had 140 weight oil, in real cold weather the tractor would start but did not have the power to move it. this can helped by adding a bit of kerosene to the heavy oil.
So this is what happens inside a differential. I wonder how it would be inside a differential like the ones found in semi trucks which are at least thrice bigger and have inputband output driveshafts.
It would be cool to see literally everything transparent, a whole car (to uncover the moving parts and the liquids), to see in one go, what's happening as a whole system :)
The volume inside the diff cover is going to be higher because it was formed around the outside of the original. It will need more oil to reach the correct level.
Running the numbers using volume of a sphere is v = 4/3 x pi x r^3: Assuming differential cover approximates the shape of a 1 foot diameter ball (it roughly does), the volume of this ball minus the volume of a slightly smaller ball inside of the first ball will give the volume trapped between the balls. The slightly smaller ball will be smaller by as much as the thickness of the metal in the differential cover. So, the gauge steel used for differential covers is about 14 gauge (about 1\16 inch) thickness, so this converts to 1/192 ft. If the first ball has an r1=0.5 foot, and the second ball has an r2=0.5-(1/192)=0.49479166 ft., finding the volumes is just using the above formula for the two balls, and then v1 -- v2 will give the volume, as mentioned before, of the space between ball 1 and ball 2. Chop that result into a third of it (only about a third of the ball will rest in the differential cover) and you end up, after converting empirical units (freedom measurements) to liters, you'll get 0.152835 liters of additional oil needed. That's like a spitball's worth, albeit a big, sloshy goober type that would sound like "THUNNNNNG" in a spittoon rather than a "ping". However, this is even wrong - the plastic was shrunk onto the outside of the flange as well as the roundout. That means that the plastic flange will end up exactly where the metal one once was (that is, bolted up against the cast iron case), which means the plastic one emulated the metal one almost perfectly in almost every way. This means that the overall volume remains almost unchanged. One wouldn't even be able to measure any change at all.
If you look at old 10 and 12 bolt chevy diffs, the cover has weird ceaces bent into the cover. They are to catch the oil running down the inside of the cover and guide the lube into the carrier bearings. Cool video 👍
Gale banks channel had a bunch of vids on rear end lubing and the new cover he designed up. And he exposed the garbage designs of most of the aftermarket ones.
Diff oil level should always be just above the bottom of the axle tubes. After you washed the diff, everything was dry. Then it picked up some oil and the level was low again. Diff oil lubricates the axle bearings at the wheel end too, and if it can't make it down the tube, bad shit starts to happen.
this is something i did when working for a driveline supplier. is used it for lube flow study's . the ring gear will send oil to the front pion bearing
When its spring time in Syberia it is 10 below great to see what happens to a differentual how the oil moves around l was watching a program in Syberia where they heated up the differentual and other parts under the van with a blow torch now l know why thanks great experiment
It would be very interesting to see these transparent-case comparisons with the proper fluids for the application, rather than mineral oil. Show us 0W20 vs 10W40 at -10C in an engine, and proper viscosities of gear oil in the diff.
Question: would that see through cover work in the long run? I mean... if you just put it on a car and go with it for let's say, years... Did you see any heat load on the plastic cover? or any leaks....? Could be a nice "tuning" for them racerboyz :D
folks in this video you can also observe what it means not to have the aluminium gasket at your exost pipe. Can you see the leakage happening at 9:13 in top corner?
Being a mechanic myself, I always wondered how different viscosities of fluid worked, in that engine, differential, transmission so on and so forth. Cool video. 👍🇺🇸☮️
guys your channel is amazing, I'm a huge fan!. I would like to sugest using a PL filter for the camera so we can see better throught the transparent case eliminating some of the reflections.
Yeah, and we don't call those planetary gears. They are side and spider gears contained within the carrier assembly. Plus, the ring and pinion make it all go around. Planetary gear are different and usually found in automatic transmissions.
There is a hall effect sensor at the back of the transmission hooked to the drive shaft. A disk with gaps spins in front of an electromagnet. The voltage to charge the magnet changes as it passes one of the windows in the disk, and the computer (speedometer) counts the pulses.
Hehe! Not on a Lada! None of that 'hall effect' electronic voodoo! The Lada speedo drive is mechanical - a gear is driven by the gearbox output and connected by a long old cable to the back of the speedo head. The inner of the cable is squared off at each end so spins inside the cable outer and so drives the mechanical speedo! Old school stuff www.lada.shop/en/lada-2107/7b2-gearbox/c7-speedometer-drive-gear-unit/
How about put some small "baffles" on the cover to direct the oil? Open a "window" in the axle housing to see what the oil does for the outside bearings? Put clinging and climbing oil, similar to Lucas to replace, or supplement the regular oil? The old "trick" for used cars: STP additive?
Lucas is pure based oil with zero additives. It foams like crazy. My rear started getting noisy after 25 miles at highway speeds. Switched back to pure synthetic and ok.
Maybe when you are driving down the road and going over bumps the oil is thrown about in more random places compared to when the axle casing is held steady.
I am reminded of warming 5 gallon cans of Caterpillar final drive gear oil in a bathtub full of hot water many years ago just to get the oil to pour- SAE 300.
The reason why you want to fill the oil all the way up to the plug until it starts to run out is so the oil level will be high enough to run down the axle tubes and lubricate the wheel bearings. Just lubricating the differential is not enough.
There’s a company that sells a differential cover I saw at SEMA a couple of times that controls the oil flow, they always had clear differential covers showing it off.
Not sure if you have done this or not, would like to see how transmission works! Is it even possible to see all of it. Thanks love watching your content and a Cheers from Canada eh 👍
There is another video on the subject showing the oem “curved” cover vs the aftermarket “flat” covers that people with pick up trucks use and the disadvantages of each. Didn’t mind at all watching the process again from you again guys , always quality uploads !
I never considered what frozen gear oil would do to a differential. I live in a climate that never gets that cold, and am now wondering if they put some form of antifreeze in the oil, or it's fine being frozen?
How fast do you have to spin a tire before it explodes. Might have to use some cheaper damage tires or see if you can make something that can spin faster then a regular car. Maybe connect the engine to the hub and the wheel where the drive shaft yoke is
It would be to use 140w and get it really cold perhaps blast with co2 extinguisher on a -40 below day , then pump liquid nitrogen in the oil, allowing it to evaporate and pop the clutch and watch oil break!
Oil transmits itself where required. The star gears do not require a lot, the side bearings require even less. Axle bearings get it as it wraps around the shafts to the bearing. In motorsport applications however some diffs require baffles in the axle tubes as all the oil goes up the tubes with G Forces. Then wants to stay there in turn causing axle seals to leak,, and starving the ring and pin of oil,, then they fail. These little Salisbury diffs are quite good standard in that respects. Try this same test again with synthetic oil. It flows far better cold. And takes a lot of heat out of the oil also,
I always knew the 4 small gears as 'spider gears' and big round gear is the 'Ring Gear' and the drive shaft turns the 'Pinion Gear'. The terminology used in this is not what I was taught. The oil is thicker in the cold but it's definitely not frozen. If it were frozen it would not allow 'ring gear' to turn.
Suggestion for a multi-show idea... In the Philippines and other Asian countries they... Modify regular motorcycles that seat many people on both sides. Sometimes called 'SkyLab'. It's used as a tourist taxi, but they are useful too for cargo and logging where only narrow trails are available. Some have roofs too. Typically a regular motorcycle is used and the rider has to have great balance .
Very informative! You guys did an awesome job. We don't have frozen oil problems here in Israel. I never realized lubricating oils can freeze. We are more concerned with thermal breakdown in the Summer months. We use synthetic oils because of that. Great Job!
Weird that this video was recommended to me. I'm in -20 degree weather right now with a hurricane force winds 115 kph winds. Literally it's Antarctica here right now and I am slightly worried about driving my truck

Diff oil level should always be just above the bottom of the axle tubes. After you washed the diff, everything was dry. Then it picked up some oil and the level was low again. Diff oil lubricates the axle bearings at the wheel end too, and if it can't make it down the tube, bad shit starts to happen.
In my experience with a lot of thermal vacuum forming, it look like the holes are too big. Optimum diameter is .040" (1. mm) - .045" (1.143 mm).
Just so everyone is clear. Frozen oil isn't usually something one needs to worry about. Most civilization exists in warmer climates.

Stock dif cover vs Square shaped dif cover. You'll be amazed of the difference in how the oil behaves.
It seems they could engineer the cover to help direct more oil out and toward the bearings when it's running at cold temperatures with thick oil.
Cool stuff fellas!
Lada with a semi truck transmission if it’s possible. I wanna see what a lada can pull with some serious gearing
like the old saying goes,
you give me a big enough lever ill move the world :D
How about overfilling the rear differential with the clear cover on?🤔
Wow. It’s not even 3 in the morning and I’m watching this.
It would be very interesting to see these transparent-case comparisons with the proper fluids for the application, rather than mineral oil. Show us 0W20 vs 10W40 at -10C in an engine, and proper viscosities of gear oil in the diff.
That would be god-level content if they did or would do that.
Question: would that see through cover work in the long run? I mean... if you just put it on a car and go with it for let's say, years...
Did you see any heat load on the plastic cover? or any leaks....? Could be a nice "tuning" for them racerboyz :D
folks in this video you can also observe what it means not to have the aluminium gasket at your exost pipe. Can you see the leakage happening at 9:13 in top corner?
How about a clear transmission pan cover?
The Narrator is kicking ass ! Equally nice to hear along with the video !
Being a mechanic myself, I always wondered how different viscosities of fluid worked, in that engine, differential, transmission so on and so forth. Cool video. 👍🇺🇸☮️
3:46 his head fits perfectly in the wheel well
guys your channel is amazing, I'm a huge fan!. I would like to sugest using a PL filter for the camera so we can see better throught the transparent case eliminating some of the reflections.
Usually in the US we use 90 weight gear oil, not trans oil like you used. I'm sure that heavy oil would've looked different in that there rear diff.
Banks power did one I believe
Yeah, and we don't call those planetary gears. They are side and spider gears contained within the carrier assembly. Plus, the ring and pinion make it all go around. Planetary gear are different and usually found in automatic transmissions.
80W90 isn't even all that thick. Its right in line with 15W40 motor oil, since gear and engine oils are rated on different scales.
Very nice work! Also we want to see a see through Automatic Transmission! 😁
Yes
I want see how the gas pedal is linked to the speed clock meter; when pedal is pressed, how the speed gets read by the clock?
There is a hall effect sensor at the back of the transmission hooked to the drive shaft. A disk with gaps spins in front of an electromagnet. The voltage to charge the magnet changes as it passes one of the windows in the disk, and the computer (speedometer) counts the pulses.
Hehe! Not on a Lada! None of that 'hall effect' electronic voodoo! The Lada speedo drive is mechanical - a gear is driven by the gearbox output and connected by a long old cable to the back of the speedo head. The inner of the cable is squared off at each end so spins inside the cable outer and so drives the mechanical speedo! Old school stuff
www.lada.shop/en/lada-2107/7b2-gearbox/c7-speedometer-drive-gear-unit/
Really? Still using a cable speedo, I thought they would have done a square wave VSS when they finally adopted fuel injection.
How about put some small "baffles" on the cover to direct the oil? Open a "window" in the axle housing to see what the oil does for the outside bearings? Put clinging and climbing oil, similar to Lucas to replace, or supplement the regular oil? The old "trick" for used cars: STP additive?
Lucas is pure based oil with zero additives. It foams like crazy.
My rear started getting noisy after 25 miles at highway speeds. Switched back to pure synthetic and ok.
Maybe when you are driving down the road and going over bumps the oil is thrown about in more random places compared to when the axle casing is held steady.
I am reminded of warming 5 gallon cans of Caterpillar final drive gear oil in a bathtub full of hot water many years ago just to get the oil to pour- SAE 300.
The reason why you want to fill the oil all the way up to the plug until it starts to run out is so the oil level will be high enough to run down the axle tubes and lubricate the wheel bearings. Just lubricating the differential is not enough.
There’s a company that sells a differential cover I saw at SEMA a couple of times that controls the oil flow, they always had clear differential covers showing it off.
Could’ve been Banks Power
This explains why my right axle seal went bad when the left didnt, i usually start ny truck and go
That Amazon wagon in the background is the best car there.
You should do a see-through intake and if you can do it a carburetor
There's a few transparent carburettors and intakes videos on RUclips
Not sure if you have done this or not, would like to see how transmission works! Is it even possible to see all of it. Thanks love watching your content and a Cheers from Canada eh 👍
There is another video on the subject showing the oem “curved” cover vs the aftermarket “flat” covers that people with pick up trucks use and the disadvantages of each. Didn’t mind at all watching the process again from you again guys , always quality uploads !
I think that one was done by Gale Banks :D
I never considered what frozen gear oil would do to a differential. I live in a climate that never gets that cold, and am now wondering if they put some form of antifreeze in the oil, or it's fine being frozen?
Id recommend filling to the level of the bearing. The manufacturers spec is for too little oil.
How fast do you have to spin a tire before it explodes. Might have to use some cheaper damage tires or see if you can make something that can spin faster then a regular car. Maybe connect the engine to the hub and the wheel where the drive shaft yoke is
I think that is what the tire ratings are for. My car requires a ZR rated tire.
It would be to use 140w and get it really cold perhaps blast with co2 extinguisher on a -40 below day , then pump liquid nitrogen in the oil, allowing it to evaporate and pop the clutch and watch oil break!
I think the last guys to need a course about productivity, are the Garage 54 guys!
Never really considered how frozen oil would behave but I guess at -30 this could be a problem. Great video and good work. Big thumbs up from me!
Oil transmits itself where required. The star gears do not require a lot, the side bearings require even less. Axle bearings get it as it wraps around the shafts to the bearing.
In motorsport applications however some diffs require baffles in the axle tubes as all the oil goes up the tubes with G Forces. Then wants to stay there in turn causing axle seals to leak,, and starving the ring and pin of oil,, then they fail.
These little Salisbury diffs are quite good standard in that respects.
Try this same test again with synthetic oil. It flows far better cold. And takes a lot of heat out of the oil also,
4:40 wheel bearings are like "so fuck us huh??? We don't need no lubrication I guess..."
Can you run a engine whit oxygen and accetilane?? Must be a big Power up....
12:41 I'm hungry now. Where did I put that box of salted caramel chocolates? 😄
if only we had Scotty's formula for transparent aluminum, all differential covers could have been see-through from the start
Haha - keyboards, so quaint :D
google for ALON, it's existing
I always knew the 4 small gears as 'spider gears' and big round gear is the 'Ring Gear' and the drive shaft turns the 'Pinion Gear'. The terminology used in this is not what I was taught. The oil is thicker in the cold but it's definitely not frozen. If it were frozen it would not allow 'ring gear' to turn.
The oil circulates around the axles and climbs out towards the axle bearings.
Suggestion for a multi-show idea... In the Philippines and other Asian countries they... Modify regular motorcycles that seat many people on both sides. Sometimes called 'SkyLab'. It's used as a tourist taxi, but they are useful too for cargo and logging where only narrow trails are available. Some have roofs too. Typically a regular motorcycle is used and the rider has to have great balance .
Very informative! You guys did an awesome job. We don't have frozen oil problems here in Israel. I never realized lubricating oils can freeze. We are more concerned with thermal breakdown in the Summer months. We use synthetic oils because of that. Great Job!
video starts at 0:52
Weird that this video was recommended to me. I'm in -20 degree weather right now with a hurricane force winds 115 kph winds. Literally it's Antarctica here right now and I am slightly worried about driving my truck
I'm curious of if you thrashed it and the oil gets hot, how it behaves when pretty hot, as well as how the plastic cover takes the heat.
That was awesome. i need one of those plastic mold machine thingers. Keep up the amazing work!
