HELP! Fitting Steel Diff LA201

[redsdreads]

HI

I am changing over to a new chassis and thought I'd upgrade the rear diff with the Kyosho Genuine Steel Diff Shaft Set.
Unfortunately the washers that go against the bearings do not fit the steel set....they are like a normal washer but with two opposite flat sides.
Do I just go ahead and fit these? It looks like the one on the longer metal part will just flap about!

Has anyone fitted this part and can explain if I need to get some new washers or if I'm just being a dunce.

Quick reply would be appreciated as I wanna get my new Losi motor in an rag this baby!

Are you talking about the diff rings?

Ok just had a look at the exploded views.

You need the part number WBD04 - pressure plate set.

don't try to build the diff with your original diff rings.

I had the same problem when i upgraded my Diff. I tried to use the orginal plates from the plastic diff, but it just kept coming loose. Can't be 100% sure that wasn't due to my lack of skills, but all seemed ok once i had the correct plates.

I find these diffs quite tricky to build, the only thing i would say is use plenty of grease, more than you would think!

If it keeps comin undone then you will defo need the plates. Jez on here is always good for Kyosho parts. Thats who i got my plates off

I find the Kyosho diffs a pure joy to build, not sure what your problem was with them.

I'll actually say please don't over grease the diffs!!!! I always try to use the minimum I can get away with.

I wrote a quick guide to building Kyosho diffs in another thread (can't remember which one) ... search for "diff" in a post by me and it'll come up.

Build them like that and they will be as smooth as silk for months at a time!

I'm going to disagree with Roger here.

My experience with kyosho diffs so far is that they're a bit pants.

Replaced all the balls with ceramic, but didn't make a lot of difference.

It feels like the spring isn't man enough for the job.

When tightening the diff it reaches a certain point when it suddenly starts clamping up. (as if the spring had become coil bound.)

On my diff there is literally 1/32 turn difference between diff really free but slightly too loose and slipping and diff fully locked. - It's virtually impossible to get the setting on the diff, and it invariably changes.

I try to set my diff so that the slipper just goes first. - This is very difficult to achieve!

I have 2 diffs and both have the same issue.

Anybody tried a different spring?

If so what fits?

This is with the steel diffs from the original zx5 kit

Make sure you have the Rings round the right way, there is a copy of theoriginal ZX5 handbook on this site under reviews.

I expect others with disagree as Roger already has, but the things that have made it easier for me are

1 - Lots of grease
2 - Make sure all parts are ckean before you start
3 - tignten the diff up until tight and then got back about an 8th of a turn.

I had the same problems as you to start with, but i did one today and it went together fine.

Keep trying
