Repairs
Bearing
Removing ball bearings from the crankshaft
Take a small steel wedge and gently hammer it keeping in between the
crankweb and the bearing.
Then use a suitable puller and take out the bearings.
Assembling the bearings on the crankshaft
Heat them to a temperature from 100C to 120C in an oil bath or on a hot plate
which is heated by a flame or electricity insert the bearings on the shaft so that
they will slide in and fit tight when cooled.
Assembling connecting rod and crankshaft assembly in the crankcase
Take the connecting rod and crankshaft assembly, clean it and oil the bearings.
Rotate the bearings by hand and check for any tightness. They should have
free rotation. Check whether the splasher pin is secured in position. The flat
sides of the splasher pin should be perpendicular to the axis of the shaft.
Fix the fly end cover on the crankshaft assembly. Insert the crankshaft assembly
through the flyend cover bore on the crankcase. Fix the free end cover on the
other side. Then fasten the end covers bolts uniformly.
