uh oh. Looks VERY different. Did you sue the same piece of wood to cause drag ?

I only ran one pass across the gears, as you suggested. I think it looks pretty much the same, just more defined in the after photo.

I see a similar angled line and one of the teeth seems similar. Were you turning the pinion flange it in the same direction as before ?

Here is the before on top, after on bottom, and I tried to outline where I thing the contact pattern is.

Well, one way to do one side, the other to get the other side.

OK so I'm stretching a little here but I seem to remember the TR-8 engine rotates counterclockwise as veiwed from in front of the car. So that puts the thrust surface of the tooth, on the convex side. Unless my dylexsia is getting the best of me, I believe that is the contact pattern that matters.

If that's the case, then the pattern actually seems to be a bit deeper into the root of the tooth than before, which might be a good thing although it's not not even anymore, across the bottom which may not matter ... It looks deeper into the root on the inner diameter.

But it looks like the darkest spot is not centered as well as it was. Now it's closer to the outer diameter as if the pinion height or something else, may have changed.

You are at a critical point with this project. Hopefully it will be ok. You'll know immeidately as soon as you get to 50-60 MPH or maybe way before that. If it's really whining loudly ... like I do sometimes ... you'll need to reset something in the ring to pinion relationship.

A press is the correct tool for installing ball bearings. The outer race of a roller bearing can be driven into place with a hammer and drift but it's best not to pound on the inner race with the rollers installed on it.

Did a quick road test today. Nothing blew up, no unusual sounds. In fact, there was a bit of a clunk that I used to have, that I thought might be in the transmission that is gone. I think it was the play in the spider gears, the Quaife has none. I don't know if the stock spider gears should, or if my are worn.

Tried a bit of power on a few corners (it was raining), didn't get the wheel spin that came so easily before, so all in all a success!

No noise at a steady 50-70 MPH lightly accellerating and lightly coasting ? If not then congratulations on a job well done !!!

If you had the choice to do it again in another TR-8 would you do it again ?

Sounds the same as it did before.

Probably. I've only had a couple of drives on it so far, but it seems to have addressed the issue I was hoping to.

Hi Darrell,

Would you have some more pictures of the installation? I'm also thinking of installing a Qauife.

Thanks,
Koen

Hi Koen,

No, I've pretty much posted all of the pictures I took. But I'd be happy to answer any questions you might have.
