67-0642 BSA SRM A7/A10 Crankshaft Worm Drive Gear
Whenever your main bush wears or you
have it replaced, the chances are that the worm gear pinion has worn too.
This pinion will also wear the worm drive on the oil pump. So
when changing your old pump for one of our new items, be sure to renew the
crank pinion at the same time – ensuring a matched pair of gears. You
know it makes sense!!

SRM's Stainless steel CNC precision engineered pressure release valve,
each one hand assembled and checked on a pressure jig to ensure correct seal
and
blow off pressure; the main problem with old PRV`s is the poor thread diameter,
some original BSA and Triumph valve were found to be 0.025" (0.63mm)
undersize
on the thread diameter, this allowed oil to bypass the valve to the blow off
via
the threads, this resulted in low oil pressure. Our valve helps eliminate
this
problem with the high accuracy of manufacture.
Use BCS Part #71-3447/SS (SRM-71.2370) - fits BSA B44, B50, A7, A10, A50, A65
and Triumph 3TA, 5TA, T100, 6T, T110, T120, T140.
