Micro-T Diff gears

[SuperFly]

I don't know what I'm doing wrong or how to solve my problem. I've just ground off my second diff gear, and I haven't seen that anyone else has had this problem once, let alone twice. It's one of the gears in the red rectangle:



I have my slipper clutch pretty tight, and the screws holding the transmission together don't seem either too tight or too loose, and I had some grease in the diff. Why am I grinding my gears off?

there ya go.

Hmmm, but I'm not really doing wheelies all over the place, and when I loosened it, it seemed a lot like my Mini-Zs when the diff is too loose and you hear a big spool-up before the car goes anywhere. I'll try running it a little looser after I replace it this time.

well, for a differential that's a bad thing, but for a slipper clutch...she just doin what she do!

put a tiny drop of oil on the slipper's o-ring. not even a drop, just a smear. think of it along the lines of polishing/mosturizing it.
you'll get finer adjustments that way instead of choosing between to loose or to tight.

mmm, that might be the ticket. The reason I had it as tight as I did was that there didn't seem to be much fine adjustment, and it either seemed like there was no slip or way too much slip. I sure wish there was a way to get to the slipper adjustment nut without disassembling the whole back end.

Just a question. The last time you had it apart, did you seat the bearings all the way? I don't know for sure if that would result in chewing that gear up, though.

You should only hear it slipping for about a foot.

With that said, I like to run my slippers pretty tight, and get plenty of wheelie poppin' action on the carpet, so I don't really think that is your problem. When the gears stripped before, did you replace just the gears, or the whole tranny? If you just did the gears, I'd say go ahead a replace the whole tranny, they're relatively cheap, eliminate all the possibilities.

You can also try and shim the diff against the tranny housing, because I'm willing to bet this is the same problem with the stock mini-t.

instead of putting an oil based lube in there just fill the diff with graphite. its sealed and well i aint had any problems with my diff. now the front end holy crap i need to make a bunch of tie rods or whatever you want to call them.
