Fiber timing gear - keep or replace

SwingWing44 · 2025-02-12T05:25:21Z

1953 210 with 17,500 miles on it since new. The car has been driving the last 20 years - not many miles per year though. I have the engine disassembled to replace the rear main seal and my question is: Do I replace the original fiber cam gear? Are they prone to early failures? I may put a couple of thousand miles on per year. It looks perfect.

Firstly welcome back Charlie.

I agree with staying with the fibre cam gear, they are much quieter than metal copies. Oil supply to the gear is the most important item in the decision to reuse or replace, good oil supply and lack of visible wear on the gear I would be reusing but any doubt a replacement would be advised.

My 216 had 89k original miles when I had the motor rebuilt. Original fiber cam gear looked brand new. I left it in and she’s running quiet and smooth.
