Sachs Clutch Disc, Radial\Lateral Play (Mitsubishi Colt)

[heylinb4nz]

About to put my gearbox back in, had the clutch assembly balanced up yesterday and the balancer (plus my mechanic) both had concerns about the radial play in the hub spline.

This is near new OEM Sachs disc with <5000kms (refaced with Kevlar up at Autoclutch recently), so my gut feel is this play is by design...ie German engineering

Now the lateral play I can understand from a even wear and smooth engagement perspective, and I wonder if the radial play is a by product of that (ie if it was fully shimmed up you couldnt have any lateral play)

Its a long shot but has anyone encountered this before ?

The problem we are trying to sort was severe gear rattle after install of the new clutch (Autoclutch job - uprate OEM p-plate + kevlar facing on OEM disc).

so far I have

- replaced input shaft bearing (some noise)

- replaced throwout bearing (worn)

- replaced trans-body torsion arm (failed)

- had box stripped down and inspected (all fine bar input shaft bearing)

- clutch assembly (PP + OEM Flywheel) fully balanced

Ballsrburning had an autoclutch issue.

hmm interesting, I wonder what it was ?

Oh well, hopefully it was a one off issue, most of the reviews out there (plus my old MR2) Autoclutch had lots of good feedback.

Car being put back together this weekend.

Sooo car back together, gear lash still there. Another 700 bucks wasted.

Next step is to dynamat the gearbox countershaft area in attemp to quiet it.

Must be the flywheel resurface that caused it.

Sorry not really getting the ''play thing'' you are talking about? Your spigot bearing or bush which ever one you have will centre the gearbox input shaft, if you have a loose input shaft then its the input shaft bearing you should be looking at. It is the most abused bearing in the box

The play is in the sprung hub in centre of clutch disc where the splined shaft of gearbox slots into. But gear lash is caused by engine pulses rotating the gears, so cant see how that would contribute, plus it didnt do it before (on same disc). My list of things so far ive done.

- replaced input shaft bearing

- replaced throwout bearing

- replaced trans-body torsion arm

- had box fully stripped down and inspected all bearings for play, all gears for wear (nothing wrong)

- clutch assembly (PP + OEM Flywheel) fully balanced

At this stage I may just drive it and see it wearing in the Kevlar clutch will help, its not nearly as bad as it was when I first had the clutch first installed and has only had 500 kms of driving...apprently Kevlar takes about 800-1000 kms.
