Singles / B31 Magneto oil seal
« on: 19 October, 2017, 14:51:32 »
Hi guys

Partway through a B31 rebuild and come to refit the magneto; I've put a new oilseal in the housing - my gut instinct says spring/open side  to the inside- ie towards the pinion or into the timing chest...  but when I've peeled the old seal off the pinion its fitted the other way round- ie spring towards the magneto.

Which is correct ?

Singles / B31 Small end bush
« on: 28 September, 2017, 16:52:32 »
Hi
Rebuilding a 1954 B31 and the small end bush is u/s- virtually in two pieces..so clearly a replacement is required. (Bike hasnt run since 1974 )
Obtained a new one but it is far roo large both internal and external. Now I've just had an interesting chat with a nice man at Hawkshaws who have stocks of "old" "new" stock but he thinks these were supplied "unfinished" by BSA and need to be machined (reamed) prior to fitting....anybody come across this situation ?

cheers

Just a bit of follow up..  Peters Classic Bike parts in Holland have stocks of all sizes of rings; not cheap but at least available

Well that proved to be a real **********.... got it off eventually ...lots of heat and a big hammer !... the nut is completely butchered but at least its off.  A lot of the problem was stopping things moving- the rear brake has seized so couldn't use that so ended up cutting a large wedge of wood and wedging this - with a rubber mat, between the rear wheel and the gearbox/frame.

Anyhoo ...thanks for you help guys   :)

Hi
I cant get the cush dive nut off (B31 1955  Plunger) ...its been really butchered by a previous owner but I cant get it to move; There doesn't appear to be a tab washer behind it- between the nut and the spring- I've tried stiltsons and a big hammer but cant shift it.......any tips gratefully received !!
