Crankshaft, Connecting Rods and Pistons
Note:
•
lt is normal for the bearings selected to
differ from one journal to another.
•
lt is also normal for there to �e two options
of bearing shell colour. In such cases, pick
the shell size which gives the greater
running clearance.
Always confirm, using the Plastigage method, that the
running clearance is correct before final assembly.
Severe engine damage could result from incorrect
clearance.
Crankshaft End Float
Standard 0.15 - 0.30 mm
Note:
•
Crankshaft end float is controlled by the
tolerances in crankshaft and crankcase
machining. No thrust washers are used. If
the crankshaft end float is outside the
specified limit, the crankshaft and/or the
crankcases must be replaced.
Pistons

Removing the Gudgeon Pin Circlip
4. Remove the gudgeon pin by pushing the pin
through the piston and rod toward the side from
which the circlip was removed.
Never force the gudgeon pin through the piston. This
may cause damage to the piston which may also
damage the liner when assembled.
Note:
•
If the gudgeon pin is found to be tight in the
piston, check the piston for a witness mark
caused by the circlip. Carefully remove the
mark to allow the pin to be removed.
5. Piston rings must be removed from the piston using
hand pressure only. Do not over-extend the piston
rings during removal.
Note:
•
If the piston rings are to be re-used, note
the orientation of the oil control rings prior
to removal.
