See Graphic: wc_gr002910
10.18.1 With the cylinder removed, check the needle bearing (a) for damage or
wear. Replace it if necessary.
10.18.2 Insert the wrist pin into the needle bearing and check for excessive
play. Replay the needle bearing and/or the wrist pin if necessary.
10.18.3 Check the connecting rod (b) for any vertical play—there should be
none. Side play is allowable. If any vertical play is present, the
complete crankshaft assembly must be replaced.
10.18.4 Turn the crankshaft by hand and check that the shaft bearings rotate
freely. Replace worn or damaged bearings.
10.18.5 If a piston ring is broken, inspect the crankcase and bearings to be sure
that no ring pieces have become lodged inside the engine. Flush the
crankcase using an oil-rich fuel mixture.
Note: When replacing the crankshaft, the crankshaft bearings and the
needle bearing for the piston wrist pin must also be replaced.
