The Excelsior Project, 35: Oil Pump & Flywheel

Autocad drawing of the oil pump. This was also a brain teaser, trying to fit everything into a very limited space.

Southern Cross CNC machined it (beautifully) from 954 Aluminum bronze, and each pump has two sets of spur gears to keep the oil moving. I didn't find out until later what a huge error I had made in the design.

New rods, old rods. New are made by Carrillo, basically a Sportster rod with a custom length.

Here's the flywheel assembly.  Sportster flywheels by Truett and Osborn, with a 3.46" stroke and custom mainshafts.

Sitting in the right side case, oil scraper in plain view.
