- With part 15 behind us, we move to a new chapter in this project with the reassembly of the Shovelhead engine. I have this bottom end, just rebuilt returned and on the stand for this task. This episode, part 16 focuses specifically on the Oil pump rebuild and installation. The pump has been stored since the breakdown and is now opened on the bench for further disassembly.
Starting with the front of the pump, Fully disassembled, all parts are washed , de-greased and then blown out with air. All passages are checked. The mating surfaces are carefully cleared with a new razor. I do not use the chain oiler so it is fully seated and capped off. The low pressure switch, which was cleaned out, receives teflon tape before re-installation.
The other half of the pump is then disassembled, all parts and pieces cleaned and inspected, de-greased and blown out. For the rebuild, i'm using James kit 89403-7306. The new seal was installed with a 10mm socket.
The oil hose fittings need to be removed for installing the oil pump so they are removed now.. The tube for the shaft on the engine is inspected for dirt before the process is started, this is followed by cleaning the face of the engine case where the pump site. The shaft is then prepared with oil and inserted into the tube a few times to distribute oil.
The gear and shaft are installed in a manner allowing for the woodruffs key to go in as easily as possible.
The bolts are progressively tightened in a star pattern from 40 , 80 to 120 in/lbs. I decided to cosmetically clean up the brass elbows before re-installation by wet-sanding them to remove all of the tool marks. They are reinstalled into the pump with teflon tape. With that the oil pump is installed, ready for the next project to get this engine back together.

this was so incredibly helpful. thank you so much for the high quality video!
Glad it was helpful!
FYI Paper and plastic gaskets use different torque specs. Cheaper paper gaskets can be thicker than HD, increasing tolerances & decreasing efficiency.
