I note from MUD that most people seem to just visit the wrecking yard and obtain a replacement 2nd-hand booster when theirs starts to give problems. But I've kinda got attached to all the original parts on my BJ40. (Also - Better the devil you know than the one you don't.) Besides, my booster is not giving me problems. It's just getting on to 30 years old without a service. - So in my books, it must need relubricating at the very least. (Yes. I never believe in the "If it ain't broke - Don't fix it" way of thinking. I believe in "Keep up the maintenance to maintain reliability".)
My garage is full of stuff like motorbikes, a concrete mixer (all in bits OF COURSE) plus lotsa tools, welders, a lathe etc - So I can't get the BJ40 in there and it stays permanently out in the weather. It's pissing down today. So I thought I'd start this thread rather than try and bring stuff inside and work on it on the kitchen table (which tends to upset the wife a tad).
Trouble is - This could get embarrasing if my "booster overhaul" turns into a disaster. (I saw that happen to a magazine contributor who was putting replacement seats in his forty series only to find after about the 2nd mag instalment that the new seat frames were too flimsy to weld onto. -- Whereapon he abandonned the whole thing.)
Here's some pix of the area to start with:
