Settings TRF501x diffs

[delanobe]

The rebuilding/cleaning of the diffs is done. Now my second question.

How tight should I put them???

When I hold the spur and turn the 2 rear (or front) wheels should there be any diff slipping or just the slipper?

Thanks again.

Still learning :cool:

You want no slipping of the diff. If anything is going to slip, it should be the slipper.

If you run your car with the diff slipping, you will create flat spots on the diff balls, and you will need to do a diff rebuild relatively quickly.

I tighten the diff so they don't slip anymore but when I turn the wheels now it's just not really that smooth. If I turn the wheel should it keep on rolling for a second or 2?


Should I loosen the slipper a bit and also the diffs?

Thanks

I can't remember exactly... but i read somewhere on this forum or rctech that you should first do the diffs before doing the slipper.

For the diffs, I think you are supposed to tighten as much as you dare first (cos I've actually stripped the nuts before) then loosen a turn or two.

As for the slipper, I think the Tamiya manual says to tighten till about 3mm of the screw is sticking out.
But i read that you can make sure its not too loose by holding on to the rear tires while the buggy is on the ground and engage the throttle.
You should hear the screeching sound of the slipper before the buggy front lifts off from the ground.
I guess that would mean the slipper is working right.

Do you mean when you turn the one wheel, should it keep rotating when you let go - as a measure of how tight it should be? uhm, well it certainly shouldn't spin 'freely'.

To test the slipper I put the car on my lap so the back wheels are locked and move the spur with my thumb. As long as the slipper is moving instead of the diff it should be ok.

Than I'm ok I think.

It's just that with my last car (vintage Avante) the diffs run really "freely" for a few seconds so I thought that it should be like that.
