Blooty hell.

Swingarm rubber had to be replaced.

Easy to remove the swingarm but ran into an issue removig one conrad bolt.
Several attempts did not work out.

One assumes that your impact won`t budge it ?

A pin point flame in the bolt recess, then let it cool

Breaker bar with a cheater pipe is my go to

Looking for the needle bearings. TLM only got two avail in store.
If 18X24X16 is the right size, vespa v50 fork needle bearing should fit for half the prize.

Is that size correct? (had to destroy mine while taking them out)

Hi Deepdive,
When i did the suspension links on mine most of the needle rollers were damaged or rusted and 2 of the inner bearing tubes were badly worn.

The cost of all those parts plus the side seals was more than the cost of two new and assembled con-rods.

Worth checking

This is what I always recommend. Just grease the new one properly before installation. The wishbone is worth rebuilding if it isn't cracked.
