Well, there's why my 3.3 won't run! Piston is facing the wrong way. Had the damn cutout facing the exhaust port. Man I've been racking my brain trying to figure out why the hell it stopped running. Appreciate the video, brother. Cheers!
Hilarious but a freaking great video. I own a T-Maxx 3.3 and my son has the Jato 3.3 and both engines are shot. Watching your video inspired me to rebuild both until I checked the cost of parts. In the U.S. traxxas wants $110.00 for each for a replacement so I'm going to use that route. Wish I could send you my .12 Picco engine from my barely used Jammin CRT.5 to rebuild. Again great video and stay blessed.
Thanks for the kind words! And it's really not hard to do rebuilds just gotta know a few things abd pay attention to how things go and you will be a pro in no time! As always thanks for watchin and KBN! 🍻
Baking bags work great. My Classic Porsche had aluminum hubs. I placed them in a sealed baking bag in my oven and heated them to about 200f baking bag so that the oil fumes don’t contaminate my oven. I do this with bearing carriers on my 4 wheeler also. Bearings fall right out. And new ones go right in.
Got a question for you buddy. My TRX 3.3 started making a rattling noise after it would warm up so I took it apart and found that the connecting rod bushing that fits on the crankshaft was pushed halfway out towards the rear of the engine. Have you come across that before? Trying to figure out why that would happen. The crankshaft bearings had just a little bit of movement.
@@michaelgraham2943 Yeah that is a common failure that's why I usually tell people after the engine is broken in about the first gallon is replaced the connecting rod the bearings and the wrist pin to tighten everything back up again and prevent that from happening.
Wow I saw your video on that before though that was being a little extreme but it all makes sense now. Thank you sir hope you get to burn some nitro this weekend take care .
Lol, for a second I saw the Dynamite head and thought you had a Dynamite engine there and this was just gonna be a joke video. Actually pretty useful rebuild vid though. I've seen quite a few 2.5/3.3 rebuild vids, and never noticed that the rod actually has a chamfered edge on one of the bushings. Now realizing, I could very well have that backwards on one of my engines. The only thing I wouldn't have done the same is putting cold bearings into a heated engine block. I'd do one or the other, but I'd be concerned that doing both at the same time would thermally shock the engine block. Although my method is to just use a piece of wood and a hammer to knock in the front bearing, which seems ok, but then for the rear bearing I put it on the crankshaft, then I slide it in as much as possible, and then I screw on the flywheel nut to press in the bearing. Not sure how good that is, but it seems to work. Also, I want one of those black heads for my 3.3!
Thanks man and not a lot of people realize the rod a put them in backwards haha and as far as using the crank to pull the bearings in puts a lot of force on the inside bearing race not the best idea in my opinion. Or if you are going to do it like that a little heat will expand the case away and take less force to pull in. The other problem is it might not be seating in all the way and that can make for some issues. But it it hasn't exploded I guess it works haha
Great video as always .Sorry I haven't been talking much lately been busy .Plus because I have that new O.S. I don't seem to have many questions for you .It run awesome I run it really fat but leaded it out and she runs about 250 safely with good power just getting ready to change the pinion and spur for too speed cause it's now got more than enough bottom end.going to a 17 38 at first and if I took to much gear out of it I'll go to a 40 tooth spur but I don't think I'll need it .I'll test and see Anyway I'm gonna rebuild my 3.3 soon so you saved yourself a lot of stupid questions by posting this video I really enjoyed it and I guess I should of just text you direct but now it's on your stream .talk so keep them streams coming!!Awesome job as always .
After having many problems trying to tune my 3.3 out of the box I put it on the shelf. It’s been a a few years and I have sparked an interest to get it going again. It still has the EZ start. I am unable to turn the engine by hand so I assume the bearings locked up. Some said to just hit it with WD40 but I was considering a rebuild. Can I reuse the rod and piston or should I buy new? I was able to find a few brand new crankshafts on the RC shops discount rack so I grabbed them. Where are you buying your better bearings from? All these guys carry is the OEM replacement. Thanks!
Yeah the bearings most likely are full of junk and need to be replaced which is pretty easy and there's only one way you're going to find out if you need a new crank or a rod or any of that is pulled apart find out. If it has very little run time they should be fine.
@@thebug4046 I didn’t even finish the break in because I think air is getting in after my carb. Also having issues with steering twitching and it slammed itself into reverse on its own.
@@kschab sounds like you have the old 27MHz radio kit. Those are notorious for glitches and runaways you can get a new 3 channel 2.4MHz radio kit for pretty cheap nowadays. Basically all the electronics upgrades are super cheap for it
Hey bug went way does the open side of the rear bearing face should I see the rear bearing balls looking through the back plate area or they post a face the front of the motor
Remove both seals from the rear bearing now that old topic is controversial I have run them both ways and never had any issue I usually put mine with the balls facing out and have never once had a problem some people say to put them in the opposite way but I'm not exactly sure haha
I got the boca bearings and am confused bc I don’t see any seals to pull on the rear bearing.. they look like they are metal and all maybe one piece? About to put it in as it came and hope for the best.. the front I pulled one and left the other on the outside of the motor the same way the stock one was.. any experience with the boca bearings and am I about to mess something up by not pulling the seals? I prayed on the metal but didn’t want to mess anything up
The connecting rod has holes right next to the bores, which direction do those holes face? I can’t tell which side is which on these rods, I can’t see which side is chamfered or not
@@thebug4046 I asked because I rebuilt mine yesterday and it just wouldn’t idle to have its life. Had to lean it way out and increase idle gap as high it would go and it still wouldn’t idle without me putting throttle trigger to it. I couldn’t find out why. New piston and sleeve, new carb, new seals all around, no cracks in the block, crank bearings are snug and smooth, the only thing I found out is my dumbass put the piston in backwards so I wanted to make sure the rod was good too. No damage internally though from it running backwards
What was that comment you made about not using hot water to clean the case because it’s caustic which eats aluminium. Can you explain that some more please?
They are a factory crankshaft designed for use with certain platforms they serve no benefits other then making you buy more parts to the same thing as the normal crankshaft they come with. Lol
@@thebug4046 ok. Great videos btw. Im waiting for the os11k carb for the jato. Putting bigger 2.8 wheels and gearing it down to 22 clutch bell watcha think? Also what pipe you recommend for mid rpms
Hello love your videos very helpful I got a question on a 2.5 Traxxas brand new motor somebody either dropped it and broke the E clip ring off I was wondering if you can use a bolt and washer to hold the bell housing on? I figured you would be the one with the answer I kind of figured you would say don’t be a cheap ass and just buy a new crankshaft ha ha 😏
Yes they are threaded on the inside of the crankshaft so you could use a small screw and washer or you could go to the hardware store and buy another eclipse for a few cents
nice video but you make a mistake the snap ring on the piston pin need to always instaledl with the opening at 6.00 oclock otherwise the snap sing can be come out cause hi rev of the piston up and down.
They can Last up to 20 gallons if you know what you're doing. The Traxxas engines have a very soft connecting rod that is poorly designed and snap after about 3 gallons. It's a good idea to replace them and the piston pin and bearings every so often. To keep them from failing
If heating with an oven is not an option. Cover with wet paper towels and microwave. I know someone has something to say. It works do it all the time with trans parts. O yeah make sure no metal is showing.
I guess you could try it and see what happens i have Never used a microwave to heat and engine a lot before hahaha im Interested to hear more about this
@@thebug4046 I use it for bearings mostly. when I I don't have time or when dinner is already in the oven. Lol 😆 the water surrounding the metal will absorb the magnetron energy. This allows the water molecules to vibrate instead of harming the metal.
@@thebug4046 ok that sounds good but im not sure of what all the parts are that I need. I already have one motor the is completely disassembled and another one that I think needs a rebuild. Because it will idle for a bit and then go full throttle and stay there or it will idle until you hit the throttle and it will then go full throttle and stay
