Minor damage to crown wheel teeth is it ok?
Turbo Mini Forums

Hi all
Just after thoughts on what is ok to use. I have bought a nos CW and p and the Cw has a couple of minor impact marks on two teeth.... they are pretty small but would this cause any problems? I don’t think it will but wanted to see what others think please

I'd be careful... make very sure damage does not protrude the surface where the teeth 'roll' over (what's the proper english term?).
In some cases small damage can cascade into bigger and bigger damage.
Having said this, I have no experience with damage in crownwheels.

Dazed and Confused....

Not a problem IMO.

The two burrs are nowhere near the load carrying part of the teeth.

But dress them of so they don't "scratch" what would be the inner (or lower) part of the pinion teeth - which is the load carrying part - and produce any nasty stress raisers.

Given the different diameters/numbers of teeth, those two could possibly scratch/mark every single pinion tooth where you don't want it.

Just dress them off smoothly and it'll be fine.

EDIT - typo

Schrödinger's cat - so which one am I ???

Agree with RodS. Dress them back and press on.

Perfect thanks chaps... yes will certainly dress them up.
Thanks for the help
