Inspection
Proper inspection and service of the cam follower is
very necessary to obtain continued efficient engine
performance. When any appreciable change in injector
timing or exhaust valve clearance occurs during engine
operation, remove the cam followers and their related
parts and inspect them for excessive wear. This change
in injector timing or valve clearance can usually be
detected by excessive noise at idle speed.
Wash the cam followers with lubricating oil or Cindol
1705 and wipe dry. Do not use fuel oil. Fuel oil working
its way in between the cam roller bushing and pin may
cause scoring on initial start-up of the engine since fuel
oil does not provide adequate lubrication. The push
rods, springs and spring seats may be washed with
clean fuel oil and dried with compressed air.
