6.7L Cummins Engine Assembly – Hydraulic Pump Drive

Install
Prior to installing the accessory drive, identify which style of gasket is going to be installed so that, if necessary, the
gasket can be properly oriented. There are two types of accessory drive gaskets:
• Three round oil supply passages and one elongated oil supply passage.
• Four round oil supply passages.
It is preferred that, when installing the accessory drive, the gasket with the 4 round oil supply passages be used. The
gasket can be installed in any orientation. If only the gasket with the one elongated oil supply passage is available, install the gasket so that the elongated oil supply passage is not over the oil supply hole in the gear housing.

For hydraulic/power steering pumps mounted directly to the rear gear housing, verify that the pump has a full
mounting flange.
A hydraulic/power steering pump that has a notch in the mounting flange will not cover the oil supply port in the
rear gear housing completely, when installed.

Use a new gasket and install the hydraulic pump and mounting capscrews.
Tighten the capscrews.
