Visit my channel for more repair videos; (3) Tap the ends of the studs with a soft mallet. Should it be necessary to replace a set of these bearings the crankcase is unbolted and dismantled in the usual way and the rings are removed from the crankcase in just the same manner as would be adopted for outer rings of the parallel roller races used previously. inner race. When you perform repairs, you need a procedure that helps you take things apart and get them back together. procedures for assembly and disassem-bly, they also dictate to the rest of the design team the design intent. (3) Secure the pump in a vise by clamping the vise jaws on the slotted end of the pump drive shaft across the slot. This applies particularly to the slotted oil control ring. The cylinder should now be inspected for condition of bore and piston rings. Figure 14 - Method of Clamping Crankshaft In Bench Vise for Removal of Rear See Figure 8.
