KIT-ENGINE OVERHAUL 3933585 - Caterpillar

Note: When Tooling (B) is removed be careful to prevent contamination. Cleanliness is an important factor. Before assembly, clean all parts in cleaning fluid. Allow the parts to air dry. Do not use wiping cloths or rags to dry parts. Lint may be deposited on the parts which may cause trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement. Dirt and other contaminants can damage the precision component. Perform assembly procedures on a clean work surface. Keep components covered and protected at all times.

Illustration 2 g06151585Note: Reuse dowel components after cleaning using clean solvent.
Do not use dowels that have been completely removed from the block. Use a dead blow hammer to install new dowel assembly in block. Install new dowel assembly by lightly tapping the dowel until the dowel assembly is flush with the block surface. Excessive force can damage the dowel or block. Refer to illustration 2. If only the top part of the dowel has been removed, Use a screwdriver to install the dowel and apply a torque of 2 N m (18 lb in).Remove the O-ring seals from dowel assembly (14). Clean and inspect the O-ring seals. If necessary, replace the O-ring seals with new O-ring seals. Remove Tooling (B) and clean oil supply hole. Install dowel assembly (14).Note: Important to replace fire ring with new fire ring.
Replace fire ring (15) with new fire ring (15). Install fire ring (15). Install a new gasket (13) onto the cylinder block.
