Checking of big-end bearing clearance

checked by means of the measuring plastic (part. No.
856927-9) as follows:
Fig. 77. Application of measuring plastic
1. Wipe clean the big-end bearing and big-end journal
from oil. Cut a piece of measuring plastic to the
same length as the bearing width and apply the
measuring plastic along the big-end journal
(Fig. 77).
Note: Avoid the oil hole.
2.
Fit the connecting rod and cap (note markings cor-
respond) and tighten the crankshaft screws.
Tightening torque, see Technical data.
NOTE! Do not turn the connecting rod or crank-
shaft since this will destroy the measuring strip.
