Thickness Of Thrust Plate - Measure; Piston Cooling Nozzle - Inspect - Mitsubishi S6R Series Service Manual

5.15 Thickness of Thrust Plate - Measure

Measure the thickness of thrust plate.
If the value exceeds the limit, replace the thrust plate with a
new one. When the crankshaft is re-ground due to wear, use
the oversize thrust plate.
For the crankshaft grinding procedure, refer to "Rearmost
Crank Journal Width - Grind" of "INSPECTION AND
REPAIR OF BASIC ENGINE."
Note:(a) Replacement thrust plates are available in three
oversizes of 0.25, 0.50, 0.75 mm [0.0098, 0.0197,
0.0295 in.]
(b) Because the oversize thrust plate can be used in
only one side (a set of upper and lower), the end
play can be adjusted with a minimum crankshaft
grinding.

5.16 Piston Cooling Nozzle - Inspect

If oil jet pipe of piston cooling nozzle is bent or
deformed, it will reduce the cooling performance, and
can lead to piston seizure.
Inspect the piston cooling nozzle.
If there is any defect such as valve malfunction and oil hole
clogging, replace the piston cooling nozzle with a new one.
