Engine Assembly (0-02) Section 0 - Engine Disassembly and Assembly - Group 00 M11 Page 0-84 Lubricating Oil Pump - Installation NOTE: Do not lubricate the two oil pump body o-rings. The o-rings will swell and the pump cannot be installed. Install two new o-rings on the oil pump body. Install the thickest o-ring into the groove nearest to the oil pump drive gear. Use clean 15W-40 oil to lubricate the oil pump gears. Apply a film of Lubriplate W 105 to the oil pump bore in the cylinder block. NOTE: Be sure the threaded oil pump mounting holes in the cylinder block are clean and free of oil or dirt. If they are not , use solvent to clean them before installing the oil pump. Caution:
The dowel pin bore in the oil pump flange (1) must be aligned with the dowel pin (2) in the cylinder block to prevent damage to the oil pump flange during installation. Do not use the mounting capscrews to pull the oil pump into the bore. This can damage the mount- ing flange of the oil pump. Install the oil pump by hand. Sealant, Part No. 3824038 or equivalent, must be used to coat the threads of the three mounting capscrews to prevent air from being drawn past the capscrews during engine operation. Caution:
The shorter flange head capscrew must be used in the upper right hand mounting hole (1) to prevent the idler gear from contacting the head of the capscrew and causing damage to the lubricating oil pump. Install the three capscrews and spacers. Use the short flange head capscrew in the upper right hand mounting hole (1). Use the longer flange head capscrews and spac- ers in the other two holes.
