Apply a thin smear of grease to each journal and a small quantity of silicone release agent to each bearing. 3.
Trim a length of the Plastigauge to fit across each journal. Fit the strips to each journal using the grease to
hold the Plastigauge in place. 4.
Note
Do not turn the crankshaft during crankcase assembly and disassembly as this will cause damage to
the Plastigauge.
Assemble the crankcase halves and tighten the fixings as described in Crankcases - Assembly. 5.
Separate the crankcase halves (see Crankcases - Disassembly). 6.
Using the gauge provided with the Plastigauge kit, measure the width of the compressed Plastigauge. 7.

Plastigauge
Record the clearance measurements for each crankshaft main bearing/journal. 8.
For specifications refer toCrankshaft. 9.
If the clearance exceeds the service limit, measure the diameter of the crankshaft main journal.
Note
If any journal has worn beyond the service limit, the crankshaft must be replaced. Due to the
techniques used during manufacture, the crankshaft cannot be reground and no oversize bearings
are available.
Select bearings as follows:
Measure and record the diameter of each crankshaft main bearing journal. 1.
Measure and record each main bearing bore diameter in the crankcase (bearings removed). 2.
