Once again buddy u r a legend, I also followed this tip of urs and just in time as my crown gear on my front diff has a chip in one tooth and pinion looking worn so again I thank u buddy knowledge is power and u r it 😉👍👌

Have a Kraton EXB on the way and have been researching diff shimming. Never thought of putting a shim/ washer behind the bearing. Usually just shim the outer bearing. Great info and thanks.

This is the last thing I need to do for my diffs, that and get some TRUE 2.25mm diff pins. The pins that come stock are definitely not 2.25mm, there's so much play on them. So hopefully after shimming up the pinion gear, I won't have any issues with the ring gear, and hopefully, after getting the thicker pins I won't have any broken sun gears anymore.

NIce! never thought to shim the pinion

Noob here but sounds like your input gear and the input shaft cup was not set right or came loose overtime and gave it to much slop causing the input gear to eat the crown gear. prob one of the things people should check before or after each run to see if the input shaft cup slid from its spot. I'm sure shimming it would be a backup to prevent it from sliding? No idea, just tossing out my thoughts.

Hi love the helpful content just wondering if this would be similar on arrma kraton 4s thanks am trying to learn

Good tip bro,but if you get good sealed bearings to replace the stock ones,this eliminates the play,also adding 2 shims on the drive side of the diff helps too! Every little helps! Peace bro...hope the Mojave build turns out good!

Thanks so much for sharing your secrets. I’m in the US. Where did you buy your 13x19x.2 mm Kraton 5S pinion schism. Thanks

posting links where to find these shims or a list of brands/ shims you use in general would help a lot of people trying to find these.

Can you use the shim that come with the truck behind the ring bearing of the pinion gear ⚙️ ?

Watched this vid when v5 is the latest model. Is this the same case as for the v5? Diff issue still? New sub💯

This was super helpful!! Does .2 mill account for heat expansion??

@bournemouthrc4371

4 жыл бұрын

Yes I would never leave it to tight, you always want a little bit of play and clearance for when everything expands. It would either rub on the cup or snap a tooth on the gear if it expanded too much

Question - I thought we are also supposed to shim between the diff output bearing and the outer case. Wont that shim effect how much shimming is necessary for the pinion gear? Since it would move the ring gear closer in. Is it a give and take between the two? Thanks!

@bournemouthrc4371

3 жыл бұрын

Yes I do both I do the pinion first then take up any space with the ones between the bearing and the case

Has anyone found the needed 19mm OD shim from a US supplier? $32 shipping from the UK for a few dollars worth of shims makes them very non affordable.

Can I use 13x160.2 instead 13x19 as it is very hard find In Australia

Why don't you have the washer AR709042 is it missing there?

Much appreciated! Are you still using arrma ring and pinions or have you gone aftermarket? I just stripped my 3rd ring and pinion on my v4 notorious (front diff) I will be following your advice, definitely getting a feeler guage to determine shim sizes

Cant you just pin the input shaft cup tighter to stop the slop? Im a noob but it seems to do the job as long as the set screw does its job. Mine has 0 slop but as i said, i'm a noob so maybe doing it that way causes issues? Also to note i have the HR diff bulkheads/case.

No the issue isn't slop it's getting the pinion to stick slightly further out to mesh better with the crown wheel

So you are ideally looking for .2mm correct? What number is that on the feeler gauge? .007 or .008? Or am I totally wrong. Thanks!

I'm having a hard time trying to find the size "13mm 19mm 0.2mm" shims. Anyone in the U.S find a seller? The closest thing I can find is from Arrma themselves with "Washer, 13x16x0.2mm (4)" , and the exact part is ARRMA #ARA709031 . Will this one work?
