The oil pan is taken off first before removing and installing the oil pump. Take out the oil pump mounting bolt from the main bearing cap after that. The block should be separated from the oil pump and pick-up assembly. If there is a problem with the latter, replace it with a new one. When doing a complete engine overhaul, it is advisable to use a new oil pump rather than reusing the old one or rebuilding it. The oil pickup tube of an oil pump should be checked for any looseness if it's pressed into the body of the oil pump. It's dangerous to attempt tightening a loose one; instead, replace the entire pump assembly. Put the oil pump in place by turning its shaft to align tang of gear with slot on lower end of oil pump drive shaft. The retainer on lower side of the oil pump drive shaft will enable easy movement of the entire thing over to its position. If not, remove it twisting tang until properly aligned with driveshaft slot in pump. Tighten up this mount using its bolt you earlier detached. Put back your vehicle's engine and start placing some engine before checking if there are any leaks.

Make sure the slot in the upper end of the driveshaft is aligned with the tang on the lower end of the distributor shaft.

Remove the pump-to-rear main bearing cap bolt.

After reinstalling the oil pan, oil should be added, the engine should be run, and any leaks should be checked for.
