Yours was not just one of those things, having the cases and diff eccentric professionally measured, it seems that the shrinkage was applied to the surface so the eccentric space became bigger rather than after the plastic shrinkage is applied to the cases the correct size, hence the eccentrics are loose in the cases.
This is proved by adding a band of insulation tape to the eccentric surface that mates with the diff cases, the clearance if then taken up. the insulation tape equates the plastic shrinkage percentage. adding shims to the diff is a work around the correct solution would be to produce new diff cases or resize the diff eccentrics to fit the over size cases. adding insulation or sellotape and shims dose not solve the problem

What a load of rubbish.. how do you know what tolerance is on the drawing for either part?!!

The eccentrics for the Laydown are the same part as for the KC, U7068, for clarity's sake.


Shimming and eliminating play are a normal part of car prep. I shim the steering and hub carriers on the cougar, the diffs have shims in them..etc.


If the eccentrics were a press-fit into the gearbox some would come out too tight (unavoidable tolerance differences in manufacturing injection moulded parts?). It took all of about 2 mins to eliminate the movement on mine. Not a big deal. I'd rather shim and pack them so there's no rubbing to cause wear and develop slop. To get that type of fit without taking that step may not be achievable without machined parts, and even then tolerances exist in manufacturing as tools wear etc.

So been reading all this but does not bother me as the gears are cut to a bigger tooth than a Yokomo,so to me less critical....
Besides does not seem to slow the people like orlowski,Neumann,Yardy so what's the problem....

I think you might have got the wrong end of the stick with what has been written about here. The LD was delayed originally with an issue in the diff area but this was rectified before the production run was finally shipped.

The most recent issue spoken about on here is not with gears and number of teeth but the plastic eccentric diff holders which hold the diff in either high, medium or low positions. It would seem that in the current production some customer are experiencing an issue where these plastics have shrunk (this happens with plastic mouldings) more than the original KC production run and therefore have more movement or slop than expected from a new part.

All I would say is that if you are not happy with the parts that come in the LD kit then speak directly to Schumacher who will be able to sort the problem out.

Those guys don't really count. They could drive a mardave meteor faster than most of us could drive this car. Noobs like me who can't setup a car for toffee get put off with stuff like this and having to shave parts of wishbones etc. And let's face it, Schumachers market is 99% club racers not world championship contenders

I am waiting the hobby shop to send me the laydown, in the meantime I am reading several complaints and issues during the build process in the rear end area. Not sure if its better to cancel my order and go with Associated or XRAY instead of this Schumacher kit.

The only issue I had were the eccentrics, that was cured with a small strip of tape. To be honest, it may not have even been needed, it was only a small amount of play.

Putting all the washers on the diff out drive as per the bag instructions made the biggest difference.
