Gearbox drain fill plug joint

[TIMMOS29]

Doing a gearbox fluid drain and was wandering if I should put a new copper crush washer on ? The old plugs seem to not have any joints on them apart from a small rubber one. Cheers

No copper washer on that model. You may wish to replace the bolt though if you have doubts about the rubber seal.

I put some ptfe tape round the threads just as a precaution.

I’m pretty sure TIS says to replace but will check.
