Title: A7 dynamo drive chain
Post by: KeithA on 24.10. 2015 10:01
Just starting to do some work on my newly acquired old BSA star twin 1952, trying to eliminate some of the nasty oil leaks
On removing the RHS alloy cover, I see lots and lots of grease around the dynamo drive chain. Is this correct>?
How is the chain normally lubricated.
Thanks in advance.
Keith

Yep, soft grease is the correct lube for the dynamo chain.

This should be useful if you have no other manuals http://www.bsawiki.com

Yes, this is fine. I will add that when adjusting the dynamo chain, be careful to not adjust too tightly, as when the dynamo strap is tightened this tends to slightly move the dynamo & tighten the chain further leading to quick wear on the chain, dynamo bearings etc

Keith.
Do yourself a favour and get a dynamo conversion kit from Dynamo regulators Ltd £77-00 plus p+p. I fit these to all my bikes where possible, low maintenance and they are quieter than the chain, also gives a better output to the battery. These are advertised in the Star magazine.
Kind regards TTJohn *beer*
