Ring and Pinion 911
 

Ok. I just put in my carrier with my new ring and pinion 4:10 gears. How much slack is ok between the ring and between the pinion? Right now it's right at half the distance. Here's a pic:

See the grease pushed just halfway into the ring by the pinion.

This is for racing only so it don't have to be perfect. I just don't want it to break. Lol.

I think you need some contact paste.

What's that

Ok. I see what your saying. But I wasn't asking for what to use to measure it. I said its right at half way. My question is what's the correct measurement? Is half way ok or should it go farther in?

I don't know too much, but I know you need to know how much and where it's contacting. Not just how far in it pushes the grease in.

Most of the gear installs I've seen reference a picture of a proper contact patch. Usually from the manufacturer.

Hmmm, where do I start?

There's A LOT more to it than that.

Backlash, contact pattern, bearing preload.

If it's for racing it needs to be perfect or it's going to break.

You need to start with gear set-up paint. Grease isn't going to cut it.

them gears are going to explode....

Horse doo doo. They are not. I've raced using this method for years. Never had a prob.

Then why ask?

Get some marking compound and a dial indicator and report back.

I am trying to do this near perfec this time though.

Yea then why ask mr professional? I call horse **** on the years of doing this.... if its worked why would you ask?

I don't need it to be so perfect. I'm not worried about vibes. I race an offroad track. I just need these things to do their job without breaking. But I'm going to use y'all's advice and get this set as right an possible.

Lol maybe this is why you keep going through gearsets

Cause I'm changing ratios.
