Cougar Diff . . . . .Again!!

[Click]

Hi Lads,

I did a search and had a read of other posts about the diff & have looked at various online vids about rebuilding.

This is what I've done:

1. Sanded diff rings using 600 paper + some WD40, kept sanding using one of the outdrives until I got a grey surface all around
2. Used new diff balls
3. Used new diff screw and conical washers + new circlip
4. Used black grease on the thrust washer
5. Used diff grease on the balls & diff rings
6. Tightened up diff fully tight & backed off 90 degrees

Diff still feels very 'gritty'?

I have another diff not built by me & it feels a lot smoother, I'm just trying to figure out what I'm not doing right?

With the circlip, I've spread the clip so there is a 4.5mm gap and did my best to get it positioned without squeezing it too much but it still feels loose in it's grove. I'm also aware there are two sides to the clip and have it orientated correctly.

So, Schumacher guru's what am I doing wrong? Why is my diff still gritty

try adjusting it till it doesnt feel gritty and make sure it isnt slipping

Hi,

Thanks for the reply. If I back off the diff screw, so the gritty feel is gone, the diff slips too easily

depends on what you call gritty, it isnt suposed to be like a geared diff as long as it doesnt feel notchy or clicky it may be ok, you probably need someone with a little more experiance to look at it i think,

Will do, it's just a bit annoying, I'm doing everything, I think, by the book but just can't get it dialed in right.

Some forums say the circlip should be so tight that you can barely move it with a screwdriver, mine moves very easily, could this be the issue?

See you on Sunday

Once again thanks for the reply. As I said I have another diff which is super smooth compared to the one I just rebuilt, so I already have a ref. 'feel' for what it should be like.

The club I race with have some very knowledgable lads, I just thought I'd have this sorted before next weekend.
