shims for knuckles and wheel bearings?
 

Where do you guys get shims for your knuckles, wheel bearings and transmissions? Or does anybody here bother with that? I have a non-crawler/slash 4x4 that has some slop in the metal hubs and I have searched for bushings and shims and found nothing. I know I've read somewhere about shimming diffs, wheel bearings etc... but I can't find that thread now

I get mine from Fast Eddy.

Traxxas #1985 teflon washer. Comes in a bag of 20

I use nitro clutch shims.

same here, or you can get some at ace, homedepot, or menards

I usually figure out the dimensions I need and then search on the "hobby" sites for the right ones.

I have a plethora of shims from kits to last me a good long while. Most of them are from racing kits like AE, Tamiya, Losi, and some Axial stuff 1/10 to 1/8. I never seem to have an issue with shimming unless it's on a go-fast rig where the bearings might rub with drive pins and whatnot. Although shimming the pinion and ring gears on a stock locked Axial axle would be an excellent idea especially when the stock gears start wearing away.

Also check the rear bearing periodically on all Axial axles especially if you run 3s and the stock plastic housings. The pinion shafts and differential assembly sometimes due to that somewhat exposed outer bearing will seize up and break those stock Axial iron cross lockers. This happens a lot on Wraiths because most of us bash them hard.

Shimming is definitely a good idea and an important key to rc maintenance in general unless you like buying new heavier duty parts down the line as the stock stuff wears out...lol.

I think the most useful shims/washers I have are steel in the following sizes.

10x12x.2 on the spool. HPI #HPIZ892

5x8x.1 for the pinions, outer stub-shaft bearings, and transmission top-shaft. Serpent #110423

NOTE: So far I've insalled 6 sets of Axial HD gears and only two sets required 1 inner pinion spacer to make the gears mesh perfectly. it's not so much important to make the gears mesh tighter, as it is to take all the "free space" out of the pinion shaft.

This means putting shims between the pinion bearings to make it a "solid spacer" setup, and then adding spacers to the outside of the pinion so that once the driveshaft is installed and tightened there is no slop in the pinion shaft. This forces the bearings to share the lateral loads pushing out from the rign and pinion and in from bashing the driveshaft on rocks. The result is longer lasting bearings.

For kingpin spacers I've been robbing the very small copper washers off of my graveyard of dead brushed motors. They measure out to 3x4.8x.1 or .2 typically. If you want to take all the slop away from the kingpins Dlux makes some killer no slop kingpin bushings that I'm running in 3 rigs.

You'll find that as you convert to Revo rod ends you'll want a bunch of 3x8x.2 washers as well.
