[Fot] TR 3 / 4 Distributor gear failure

[n197tr4 at cs.com]

 Chris,

Is this OEM gear or aftermarket?....if there is an aftermarket offering.

What about hardening the mating gear?

Great to see the FOT LIST alive with valuable information.

Update:

After the hardening I can report some success!!
The teeth show NO wear anymore.
The contacting surface is glossy polished but no marks of teeth digging
into.

>From my point of view it should be advisable to plasma nitrate harden the
gear wheel to a depth of 0,2 mm.

Cheers
Chris

I would like to give an update:

I did a hardness check on the distributor gear:

HRC 38 to 43 (stock)
After plasma nitrating
48 - 54 HRC

So the surface is now harder and I'll report how the gear will behave.

Cheers
Chris
