Anyone have any Traxxas 3.3 parts they want to get rid of?
I'm fixing up a T-Maxx 3.3 for a friend that is moving out of state. I'm fixing the truck and selling it for him. The rear bearing ball retainer puked which took out the rear bearing, conrod, Crankpin stub for pullstart, and made a little mess in the crankcase. I have a spare conrod, set of bearings, and the crankcase is salvageable... I just need a good pullstart 3.3 crankshaft. If anyone has a good 3.3 crank they'd part with cheaply, please let me know.

I have 5 of those myself, while they will work, the inlet port and channel inside the crank is much smaller in the 2.5 crank versus the 3.3 crank. I doubt the 3.3 would even make 2/3 the power it normally does with a 2.5 crank. I thought about grinding one of the cranks I have, but I don't have a way to chuck it up to drill the center of the crank out. No lathe, otherwise I'd just do that....

The part number I'm looking for is Traxxas 5288, 3.3 crankshaft with IPS for use with a pullstart/EZ-Start. It's too bad they don't use the same crank in the 2.5 - I'd bet the 2.5 would really wake up with a 3.3 crank in it given the size of the inlet port and port runner. I might have to experiment a little with a basketcase 2.5r I had repinched.

When I originally posted this, I figured there'd be enough people with Traxxas stuff to dump that I would be inundated with replies... Turns out I was wrong! After seeing the factory price of a crank at nearly $40, I hoped for some used stuff being super cheap - I don't have a way of ordering online anymore so I'm left with paying cash and buying local or sending postal money orders for payment.
I'll post pictures of the carnage that I'm repairing a little bit later. Literally a chain reaction of failures - a Rube Goldberg device almost..

I will do that!! I don't know if they sell retail off the street though - they may sell online only... That's what I'm afraid of. We'll see. Hopefully I hear back from them tomorrow.

For what it's worth, these are the parts I'm replacing. I already had a good set of bearings in another crankcase as well as a good spare conrod. My theory is the rear bearing cage let loose, caused the crank to wobble, the IPS broke off the crankpin and bounced around inside, bound up the rod and took out the big end of the rod. You can see by the color of conrod that the engine was never run lean because the small end of the rod isn't black from burned oil.
Traxxas actually uses reasonable quality Japanese bearings, so to see a failure such as this (plastic bearing retainer) is bothersome, it isn't all that common. Plastic retainers are supposed to be the gold standard for handling higher rpm compared to the metal retainers in standard bearings.

Heard back from Dollar Hobbyz. They are't zoned for retail sales and don't have a storefront so they won't let me pickup locally. They sell online only. Bummer.
