INTRODUCTION The steps to disassembly of the S1, S2, H2 crankshafts are the same as the H1 disassembly. The steps in rebuilding the S1, S2, H2 crankshafts are the same as that in the H1 manual except for three changes:

1. Steps 4 through 9 are the same except that the main bearing axle is pressed down into the outboard cylinder crank half instead of being put into the bottom of the pot.

2. The center cylinder is put together last through the use of the new pusher plate that allows you to push directly on the center flywheels.

3. Truing of the crank is done by supporting the crank on its two outboard main bearings instead of the inboard main bearings.

This is the prescribed manner in which KHI feels is the most accurate means of checking the crank. NOTE: All the specifications, procedures, part numbers and prices subject to change without notice.
