17.Hold the pump rear assembly with a wooden fixture, or other suitable device, in order to secure it while removing the crankshaft (18). Using a plastic mallet, tap the crankshaft (18) from one side while turning it from the other side. The turning insures that during this sequence the crankshaft does not become wedged agaisnt the connecting rods (20). The far side bearing (15) will remain in the crancase (1).
