Rebuilding Connecting Rod Assemblies
If you are rebuilding the connecting rod assembly
using component parts, follow this procedure:
When replacing the piston cup (4), be sure to
replace the sleeve (1) at the same time. Place
the con rod shaft in a fixture before attempting
to remove the retainer screw. Heat will help
to dissolve the loctite bond.
1. Remove the retainer screw (2) from the cup
retainer.
2. Remove the retainer (3) from the connecting
rod.
3. Remove the cup (4) and discard.
4. Place the new piston cup (4) on the connecting
rod.
5. Place a piston cup retainer (3) on the
cup/connecting rod making sure the boss of
the retainer is seated in the pilot of the rod.
6. Insert the retainer screw (2) into the connecting
rod (5) and tighten to 95-105 inch-pounds.
Attention
To replace the connecting rod and
bearing assembly turn to page 19.
