ri702bill 10,036 #3 Posted August 19 Tapered output shaft per the diagram - inline axial load from generator Not meant for pulley side load.. Not a good overall choice for a WH. If it's free -then carb, head, valves, etc are spare parts. Maybe the block too.... 2 1 Share this post Link to post Share on other sites

Looks like the crankcase picture shows two different side covers? One shows a ball bearing which is what I understood is side load compatible? The other is unclear to me.

pfrederi 18,969 #5 Posted August 20 It is a service engine It has Ball Bearings on the crank 231625 The crank is a straight crank 231797s for some reason the picture in the manual is bad but it is very similar to 231761 Should work fine for a WH 1 Share this post Link to post Share on other sites
ri702bill 10,036 #6 Posted August 20 I based my text upon the Partstree diagram.... that showed the tapered generator style shaft. Straight shaft - good. Ball bearing for side load - very good. Share this post Link to post Share on other sites
