REPAIR (Cont)
NOTE
If new cam follower assemblies are to be installed, remove the preservative by washing with
Cindol 1705 and wipe dry. Do not use fuel oil.
Before cam followers are installed, immerse them in clean Cindol 1705 (heated to 100-125 or
F
38- 52 ) for at least one hour to ensure initial lubrication of the cam roller pins and bushings.
C
Rotate the cam rollers during the soaking period to purge any air from the bushing-roller area.
The heated Cindol oil results in better penetration as it is less viscous than engine oil and
flows more easily between the cam roller bushing and pin. After the cam followers are
removed from the heated Cindol 1705, the cooling action of any air trapped in the bushing and
pin area will tend to pull the lubricant into the cavity.
Heat the Cindol 1705 in a small pail with a screen insert. The screen will prevent the cam
followers from touching the bottom of the pail and avoid the possibility of contamination.
