REPAIR INSTRUCTIONS ASSEMBLY Refer to Figure 242. 1. Install oil pressure relief valve plunger (11) in relief valve housing (4). 2. Install oil pressure relief valve spring (12) in relief valve housing. 3. Clean oil pressure relief cap (13) and install in relief valve housing.
To maintain correct oil pressure for various oil system arrangements, the proper oil pressure relief valve spring and cap combination must be used. Using incorrect components may result in either high or low oil pressure, and contribute to premature engine damage.
It is extremely important that pump application be checked prior to drive gear assembly. Several drive gears are available to establish correct oil pump-to-auxiliary drive gear ratio combination. Failure to select proper drive gear for application will result in gear and engine damage.
