5) Connecting rod
Distortion and parallel
Install the measurement tester as figure.
Measure the distortion of the bigger and
smaller end bearing holes after that do
as regard parallel of both holes and if
abnormal, replace the connecting rod
Amounts of wear
•
After assembling the connecting rod in the crankshaft measure the clearance between
connecting rod bigger hole and crank pin diameter using filler gauge.
•
Assemble the connecting rod in the piston and then measure the clearance of these parts.
•
If it is more than the use limit value, replace the connecting rod.
6) Piston reassembling
•
After heating the piston at the piston
heater for about 5 min (120 ~ 150
˚
C),
by aligning the piston pin hole with the
pin hole of connecting rod’s smaller
end, insert the oil coated piston pin.
NOTE : Confirm the direction of
connecting rod and assemble.
•
With the snap ring plier, insert the
snap rings of the piston pin.
•
With confirming the upper side
indication of piston ring, after
assembling the ring in the piston ring
groove, inspect if the movement of
ring is smooth.
•
Arrange the assembled piston in order
as the cylinder number.
