Install the housing in a chuck on a lathe.
Use an indicator to put diameter (A, Illustration 8) of the housing alignment with the centerline of the lathe chuck.
Machine 3.05 mm (.120 in) from gear bore diameter (B, Illustration 8).
Illustration 8
Location of diameters (A and B), bottom face (C), and outer face (D) of the housing.
Never remove any metal from the bottom face (C).
Put a thin layer of Belzona Molecular Release Agent on the bottom face (C) and outer face (D) of the housing to prevent adhesion (permanent contact) with the Belzona Molecular Metal. Allow the Belzona Molecular Release Agent to dry for ten minutes.
Add Belzona Molecular Metal to gear bore diameter (B).

Example of heavy damage:
Do not use again
Illustration 18
This type of damage is an indication there was not enough contact area for the camshaft serrations.
Do not use again
Illustration 19
More than one set of serrations is an indication that the drive sleeve has been reused.
Do not use again -
because a drive sleeve should only be reused once.
Illustration 20
Single set of serrations.
