Engin Rebuild

Featured Replies

hi all am just about to start a rebuild on a 199A engin dose anybody know is there 1 or 2 main bearings on the right hand crank side? i only ask because the depth of the crank case looks like it taks 2 bearings. also theres a thin metal wire in beded in the crank bearing area with a gap in it any ideas? this is on the same side. i got 7 bearings from bultaco uk this is a full set theres 2 small lay flat bearings 4 big bearings and 1 medium size bearing. i know where all the bearings go i just want to know why have i got one left over?

For the 199a model on the clutch side there should go two bearings for the crankshaft in the engine case,

(The 199b (first batch / production run) have a instead of two single bearings ome double ball bearing at the same location)
