OK - it's my understanding that the product D 2.5 kit attempts to use a smaller input pinion on our regular size diffs. This alone is going to lead to obvious meshing complications as the gearboxes themselves simply aren't designed for this configuration.

Theory aside for one moment - no wonder you're finding it difficult to get the mesh right.

Regards hope for your Yok - course there's hope - go back to the original drive pinion and the problem will go away!

How many Yok SD drivers at the worlds were using the Product D 2.5 ratio kit.......?

Hope you get your car sorted soon.

Regards

Horatio

Thanks though,

Well, as the gears are new you will have to check the teeth for any trace of flashing that may be left over from the moulding process. Use a sharp knife/scalpel to remove any surplus material. Also bear in mind that diff gear (crown) it's a good idea to replace the drive pinion at the same time.

The gears also need to bed-in and only when this has been done will you attain total silky smoothness.

Hey guys I have been trying for over a week to fix a little problem in my SD Rayspeed Diffs. I had tried the Product D Bevel gear change and coundn't get the gear mesh right in the Diffs even with every possible shim configuration. I went back to the original gears and still have the same problem. The front and rear bevel gear isn't matched up like it should be. I even tried to shim the Diff it self to the side which I think creates drag and didn't want to but was desperate to get it running and after about one minute it would have the same gear grinding noice as before. I have new diffs new gears, new diff cases and new shims should I shange them also? There isn;t any real sign of wear on the current gear and diffs(they were just rebuilt).

IS THERE HOPE FOR MY YOK?
Thanks,

Maybe a long shot, but have you checked your input shafts? They can sometmes bend in a bad crash.

Try checking the the spacer amount on the input shafts, they are the spacers in between the input gear and the bearing.

This Thread is titled Yokomo MR-4TC SD
So it is the SD that we are talking about here but the CGM gets a couple of blurbs every now and again. Basically the car is the same except the chassis. The SD SSG is Carbon fiber and the CGM is Grafite. I personally like the Rayspeed upgrade to the standard ssg chassis but that is my preference. The SSG is a real nice racer. My friend races his CGm and he is fast with it also so what it comes down to is do you like Carbon or Grafite?
There is your answer.
Hope this helps
Stephen <><
There are slight variations but the car is the same minus the Chassis.

I think the best combo is Yoke SD CGM converted to Rayspeed chassis.
You get lightweight chassis and all of the graphite parts.

so you buy the car for 270, then spend another 150 on the rayspeed conversion?
