Isuzu — Important Operations (Disassembly Steps - 3)

A Isuzu service procedure — check it applies to your exact model before use.

Procedure

3. Flywheel Block the flywheel with a piece of wood to pre- vent it from turning. Loosen the flywheel bolts a little at a time in the numerical order shown in the illustration.
6. Camshaft with Camshaft Timing Gear and Thrust Plate Remove the thrust plate bolts. Pull the camshaft free along with the camshaft timing gear and the thrust plate. Note: Be careful not to damage the camshaft journal, the cam, and the camshaft during the disassembly procedure.
8. Connecting Rod Cap with Lower Bearing If the connecting rod lower bearings are to be rein- stalled, mark their fitting positions by tagging each bearing with the cylinder number from which it was removed.
9. Piston and Connecting Rod with Upper Bearing Remove carbon deposits from the upper portion of the cylinder wall with a scraper before remov- ing the piston and connecting rod. Move the piston to the top of the cylinder and tap it with a hammer grip or similar object from the connecting rod lower side to drive it out. If the connecting rod upper bearings are to be rein- stalled, mark their fitting positions by tagging each bearing with the cylinder number from which it was removed.
