253. It should be possible, by light thumb pressure,
to push the gudgeon pin through the connecting rod
bushing (close running fit).
254. Use special tool part no 9995309-3 to press out
the connecting rod bushing, if necessary.
255. Press in the new bushing, using special tool
part no 9995309-3.
NOTE! Make sure that the lubricating holes in the
connecting rod and in the bushing line up with each
other. Check the connecting rod for straightness and
twist. If not straight, replace the connecting rod.
256. Check the crank bearings and the main bearing
journals. Measure with a micrometer at several loca-
tions around the diameter and length. The 'out-of-
round' on main and crank bearing journals must not
exceed 0.004 mm (0.000157"). The taper must not
exceed 0.004 mm (0.000157") on any of the jour-
nals. Should the measured values exceed the above
given tolerances, the crankshaft should be ground to
the closest undersize. See 'Technical Data'.
