Outcast Outcast Diff Shimming

[skeeler]

There's been a lot of discussion about how the Outcast's diffs need to be shimmed. I have an Outcast on the way, and I've also purchased some the shims recommended. Can anyone give me guidance about which gears need shimming and how many shims of what thickness are recommended?

Thanks.

@skeeler here is a great video on how to shim your diff's.

The part numbers you want for shims are either:

AR709024
or
TD310475

Unfortunately both appear to be out of stock at the moment.

Thank you for getting back to me. I'll certainly review that video. I have the parts on back-order via Tower, and they are expected to ship in the next few days.

Edit: The video is very helpful. Thanks again.

I was going to hijack your thread but then I just decided to make a new one.
FYI I don't know which shims you are planning on using.

Duperbash has bought them all up. He has like a dozen Arrma's. Pretty rude I know.

Doing some ramps jumps and I broke the left side planetary gear on the front diff,didn't have any shims at the time.

How rude

Thanks for all the information. What's needed to correctly shim the pinion gears front and rear?

 

[Fahd]

Am I getting this right?

7 shims per differential? 6 on the cross pins and 1 for the planetary gear?

Looks like the washer he uses on the planetary is different than the ones on the cross pins, but those two part numbers show the same shims.

Anyone change the viscosity of the oil after shimming their diffs? or just use the factory Arrma stuff?

There are entire threads on this topic, so poke around. I'm running 50k front, 100k center, 30k rear.
