I think that Synchro909 may be correct. I do remember years ago reading something about the early worms that were incompatible with the new bearings. Thanks for reminding me about that.

I will order a new worm and shaft from Brattons.

BTW I have been really impressed with the service from Brattons. I have recently bought a number of parts from them with excellent delivery times and service.

Thanks for all the responses. This is a new ride for me and I will post some more pics later.
