Can't seem to get slipper clutch to hold

Claspers · #1 13-09-2012

Any advice for a dex210. Built the ball diff v v carefully and it runs smoothly. Attached the slipper clutch and finished the build. When testing in the kitchen, all I need is a tiny amount of power and the slipper squeals. Cant seem to get it tight enough to get close to being punchy off the line. Is this normal?

If its making a squealing noise then it could be your diff that's not tight enough and not your slipper.
Try tightening the diff an eighth of a turn and try it again

Squeal - diff

Make sure to use a very minimal amount of grease in the diff. I've seen a few over greased leading to the diff feeling good in your hands, but there is little or no drive when in the car and plenty of chirping/squeeling from the diff.

No harm giving the slipper pads a very light sand just to take the shine off them also.

Was it quite high pitched? Looking at the pads there looks to be a really shiny surface. I checked the diff so carefully but I guess it could have loosened after breaking in?

The layshaft bearing might be compressed if it wont tighten?

So far have roughed up the slipper pads, tightened the diff about 1/2 turn and no difference. Back to the drawing board!

is the gear diff likely to help at least eliminate one possible issue do u think?

On the lay shaft is a big silver tube. If you have overtighened your slipper it gets damaged and the slipper won't bite.

Swap that bit for a new one

Remove the gear cover, grip the rear the car in one hand in a way that you can hold the spur gear tight with the thumb of that hand.

Hold one of the rear wheels between your knees.

With your free hand turn the other rear wheel.

When you turn the wheel look at the slipper plates.

If the plates turn but the spur gear does not ('cos it's held tight with your thumb) then it's the slipper.

If the slipper plates do not turn it's the diff.

Let us know how you get on.

Thanks all, ended up taking a punt and gave the diff a near enough full turn. Looks like it had loosened whilst breaking in and was probably too loose from the build. Plenty of punch now ! Thanks all. Great advice all round

The new one seems to be made of a different material (looks not as "Silver") - harder I guess - Fitted one to my lads and good as new again
