Kraton Another 29mm diff question. 🙄

[Jeremy15086]

I am having issues with my rear diff on my K6 exb bla bla bla...
I opened it up for the 3rd time today. I had rebuilt it with chipped gears because I was waiting for a 29mm aluminum diff case from Arrma that I ordered from my LHS. Well it hasn't showed up and this diff was not holding up. I figured I'd take it apart today and it would be a mess inside. To my surprise nothing has changed. But I noticed that there are no LSD plates or delete plates. I know this one came with an open diff because it was an older one. But where is the replacement for those LSD plates? These 3 washers?

Do you want the LSD setup? Need to order the LSD star plates and the shim kit Armma put out for the 29mm if this is what you want to do....?

Those three washers look like they go under the sun gear.

To run it as an open diff, you need this kit: https://www.horizonhobby.com/product/diff-shim-set-fits-29mm-diff-case-3-diffs/ARA311094.html

The large ID shims are the ones that replace the diff plates.

If you want to rebuild it as a LSD, you need a new set of plates as @parcou mentioned: https://www.horizonhobby.com/product/active-diff-plates-exb/ARA310984.html

The picture I posted is everything it came with from the factory...
The only additional things are the shims that go between the housing and the bearings. I did my own setup today. I made some stronger output shaft pins from panio wire and used some heavy duty washers to reinforce the sun gears. It feels better then any other diff I have done so far. I'll see how it holds up now.

If you have the time, this is a GOOD READ! Brain solved the puzzle!

What I followed and many of us with the open diff in the Kraton rear followed. I added the LSD stars to strengthen it... Get a drink and read...well worth it and bookmark it!
