View Full Version : replacing backplate bushing with bearing.

Can you replace the bushing that supports the starter shaft on the backplate with a bearing? my bushing is wore and i was wondering if you could do that since it would be less friction and better sealing (than a wore out bushing anyways) moderators?

You can't do it, man. My friend wrestled with this on his Stampede for several weeks before he realized that much time and $17 worth of bearing were spent in vain. If you install a bearing (sealed or non-seled), the engine will start and then idle progressively higher until it quits. Somehow the bearing doesn't allow the crankcase to bleed off enough pressure. I asked Traxxas to explain it to me in this forum (ah-hem) but no one ever did.

Yeah, I tried it, too. Had some bearings that fit and an extra backplate. My bearings weren't sealed and it caused a major air leak and though it didn't die, I couldn't get it to idle correctly, either. I thought maybe sealed bearing were the answer, but maybe not? There's got to be a way to do it and eliminate the wear and blow-by that continually fouls up the one-way bearing. Not to mention a power increase from bearings instead of a bushing!
Come on, Traxxas, give us the scoop! Surely you guys could accomplish it if you set your minds to it! Or is it a cost prohibitive issue? Hey, I'd be willing to pay a little extra for it, as I'm sure most others would be, too. And it'd be great PR for Traxxas, as well!
