PUMP GP-ENGINE OIL 5667305 - Caterpillar

These pumps have a locking screw (3) and a spacer (2). The locking screw prevents the rotation of the drive shaft when the pump is removed from the engine.An O-ring (1) is installed in a groove in front of the pump flange. This O-ring is installed instead of a gasket between the pump flange and the timing case.
The drive shaft of the pump must not be rotated without the spacer in position under the locking screw. If the drive shaft is rotated, the pump drive shaft will be damaged.
Engines with these pumps do not have timing marks put on in the factory, but there is a timing mark on the pump flange.Other features of these pumps include:* A boost control (4)* An engine stop solenoid (5)* Electrically operated cold start device (7)The high-pressure outlet for number 1 cylinder is shown at (6).A new pump will be received with the locking screw installed and the spacer retained by the locking screw, but free to move.
