If any of the parts on the engine oil pump are worn or damaged, the entire pump must be replaced.
Note: If the No. 1 crankshaft main bearing cap was removed, install the No. 1 crankshaft main bearing cap with the engine oil pump. Tighten the bolts for the No. 1 crankshaft main bearing cap to a torque of 265 40 N m (195 30 lb ft).
If the shaft for the idler gear on the engine oil pump of a 3054 Engine was removed, remove the old sealant. Apply a fresh layer of Loctite 603 to the bore in the main bearing cap and use a suitable press to install the shaft.
If the shaft for the idler gear on the engine oil pump of a 3056 Engine was removed, use the following steps to install the shaft.Note: If the shaft on the 3056 Engine was not originally installed with a pin, the pin must be installed.
