Good evening Guys and girls.
I need some advice with regard to stripping a BSA winged wheel.
I bought the bike in the spring of this year and it has sat laying fallow up to this month when it is now vying for workshop time. It came from a deceased estate and has the potential for being a nice thing as the engine is mounted in a period BSA postie's bike.
It has not run for many years and clearly some remedial work needs to be carried out to the engine. To that end I removed the engine from the frame and commence dissambly. It is clear that there are several small pieces missing which lead me to think that a previous owner has started to take it apart and then given up. The two small woodruff keys on the magneto side of the crankshaft are missing as is the locking ring on the rear sprocket freewheel mechanism. I am lead to believe that the pedal rear sprocket should simply pull off with its drive sleeve once the external cup and cone have been removed. However although it is possible to move the sprocket and sleeve about 1/4 of an inch there is then a dead stop which makes me wonder if one of the bearing rollers has moved on the input shaft. I am reluctant to pull with any significant force as this will only result in bent /cracked metal which is best avoided.
Can anyone give me some advice about moving this forward
Best wishes,
Steve Pryke
