| IMO, if it ain't broke don't fix it. The instructions in the Haynes will show the crank removal etc. not sure if they cover the plug??
The steel one should fit, i don't know if the thread is the same, should be.
Unless you "really" want to, i'd leave the bottom end alone. The very least you'd need to do is replace the mains and reshim the crank. Get that wrong and the plug will be the least of your problems.
If I have a crank out, and the plug is secure then I dot punch it around it's circumference. Staking it with the chisel is the same theory.
They were known to come out, but very occasionally. It's a lot of work and £'s just to discover your's is OK and if you should get the reassembly wrong then it'll do some serious damage.
If you really want to do it, your confident and have the tools then fine, but if not, i'd leave it............. |
