Takes its own oil, has a plug on the side, diff fluid change intervals weren't common for me lol

I no longer have the truck as I upgraded, but I remember one on the dash like normal and one inside the glove box forsure, maybe even in the driver door jam.

I tried re-adjusting it to several different positions, in order to have enough pedal to be able to get full throttle the pedal was straight up and down, wasn't smooth or comfortable by any means!

Best of luck! They are great trucks, I'm sure a 427 was an awesome option over a 366, but although not a powerful engine my 366 didn't ever want to stop working! Thank you.

The loud youtube music wasn't so helpful, tho. :(

But overall - the Russian Judges award you a 8.7 out of 10! (Seriously - lots of little helpful tidbits that applied to my 1974 Ford F600 w/ Eaton 2-speed single reduction rear end.)

Get her fixed! Best of luck!

Yes. I washed it up to go through and inspect everything before I ran the new wires to help narrow down any issues. Could have been several other issues that I would not know without looking it over, as it didn't work when I bought it and I didn't know why it was unhooked. What I did worked perfectly fine, 2 speed still works great.

It would have already went through way worse over 50 years of salt, mud and sloppy roads then what one good pressure washing is ever going to put it though.

300hp was the only number I could find after researching. now to say the least after 50 yrs of 3400rpms screaming for hrs at a time down the highway, I'm well aware she was tired and no where near that anyways. But it never let me down I will say that!

No!

336 doesn't exist that truck does have the 366ci as I misspoke.

It is infact a 366, It still gets mixed up from what I'm thinking to what I actually say! Haha

Follow the hydraulic lines and see if it goes to a tank, some scissor lift cylinders I believe you add fluid right in the cylinder I've heard

Almost never! They look horrible fast but they are the best jackets I've found in my opinion

Yeah nothing beats a skidsteer for that kind of work. I had to make the choice between the two as well. And decided the mini ex was best for my use. Just have to sacrifice in some areas! I have since bought a very small skidsteer for plowing as it was a painful task in the excavator.

When you say keep trying to run after you turn off the ignition, are you referring to a few second chug a lug until it dies? I have noticed recently on my truck occasionally when I go to shut it off it will run for a few seconds after that for what ever reason. I have not diagnosed it yet. And the two speed not engaging, is that when you are up or down shifting? I know if if it doesn't idle down enough it will not engage when shifting to high, but you will also get a loud ratcheting clicking sound when you shift to low, and you have to mash the gas and rev it up until it reaches proper rpm and it will catch. Also I have noticed to never hit the 2 speed if you are in neutral or shifting between gears, only once you are in a gear with clutch out then you shift the 2 speed. Otherwise occasionally it will get lost and start a loud clicking and won't engage until you come to a stop. Hope this helps you out.

Yea my mine will keep “dieseling” after the ignition is off until I put it in gear and let out on the clutch. I’ve researched a little and some say it’s timing and others say carb issue. I figured I’d ask. As for the rear end. It’s like what you said where I have to come to a stop or slow down significantly till it catches. Usually after I try to split and shifting from third high to 4th low. Could be operator error. Lol

I'd be more inclined to believe it is timing related, only tends to do it after I'm using it a good bit, never did it at first but I did play with the timing to try and get a bit more power, which worked. Now it doesn't turn off right away some times just havnt looked into it yet. And yeah as far as the 2 speed goes when I shift from 3 high to 4 low I'd make the shift in 4 high technically, I'd push the switch and rev it up kind of all at the same time, (I don't typically use the clutch shifting up) ive tried hitting the switch mid shift so once I let the clutch out I'm right in 4 low, but it won't re-enguage like I feel it should. Keep playing around trying different tricks. I was worried my 2 speed was messed up when I started using it, I figured that's why it was unhooked when I bought the truck. Just took me awhile to get the hang of it, now I can cruise through all the gears high and low pretty smoothly.

Okay I will try that! Thank you for your input. Great videos keep em coming!

The timing is advanced too much, the truck is running too hot or the engine idle speed is too high. Maybe all 3. If you have the vacuum shift (Vac pot on rear diff) you might have a vacuum leak. Electric shift (electric motor on rear diff) could be out of oil or contact switch inside is burnt. Check oil level at the small plug on the front of the 2 speed box. Should be shifting instructions on sun visor, read these too.

You bet. When I get a chance to do something that I'm not able to find on RUclips, I try to share as I learn to be able to help others as best as I can!

It is not, bought it to fix up and use for my hobby, and this thing is my favorite!

i have one for sale. 72 C50 4+2 speed

If I remember right I put 75w-140 valvoline gear lube in it when I put it back together

@@Tanner30657 thanks for the reply. Everything i can find on it calls for straight 10weight oil, but its a rare oil these days. Got a Eaton speed in my '73 D600

@@dilksy86 you bet! yeah it's getting hard to find the recommended oil now days, so you'll more than likely have to improvise, that's what I've been doing and have had solid luck so far.

@@Tanner30657 I ended up finding the closest thing I could, SAE 20W oil at Lowes. 3InOne Oil brand makes a straight 20 for "Electric Motors", working great so far. Not looking forward to changing that differential seal out later on, got a leak at 2 of the lower bolts.

As long as it's slippery you should be okay haha, I'm a firm believer any oil today is better than what they had then! I wouldn't be excited to change that seal either, never goes as easy as it should

If there was an easier route I would have taken it. The lever by the fire wall had already been broken off/ cut shorter and was no longer factory so there was no adjusting it back to "factory". I had to add back on to it. I had already adjusted the knob that connects to the carberater, but being the lever by the firewall was shortened for what ever reason it couldnt provide enough leverage to transfer my little bit of gas pedal travel into the amount of movement required to open the carb all the way. When I did make adjustments to the original setup the gas pedal was leaned back towards the driver probably close to 70° and took about 6 inches of gas pedal movement to get almost full throttle on the carb. After my "mcgyverism" I can now go from an idle to full throttle in about a 3 inch motion on the pedal, and it sits at the proper angle and is comfortable to drive now. Had to be done!

I think the gvwr is around 32,000 so legally roughly 22,000 it could tow

Is that for a thumb that pivots on the same pin as the bucket? Or a weld on style?

@@Tanner30657 pivot like factory. 1500 plus tax on eBay the cheapest it’s very handy. My 121 has 4000 hours runs like it’s new.

That is what I tried first, was only able to get about 3/4 throttle.

Right on!

Thanks 👍

That was my first thought, but the angle of the old setup even shortening the linkage wouldn't quite get me full throttle, and redoing it the way I did, I was able to get the pedal lower to the ground and still get full throttle, even though it was more work it was worth it, works awesome now!

I've heard lots of good things about them! So I figured for the money I'd give it a shot, and I'm loving every minute of my decision so far!

delete the fuel bowl ?

I am considering doing the same, I have a leak where the fuel shutoff screw is and doing away with it would be the simplest solution

Yeah I'm not sure how they are supposed to be, but will be changing it either way since she's rotten!
