Laycock de Normanville D-Type Overdrive Disassembly | Triumph Spitfire Restoration - Part 91 

Thanks! This smaller one is cute.The A-H3000 used engine oil, non-detergent spec but probably not used as it was hard to find even in the mid 60's. The solenoid adjustment says use a pin through a hole in the lever. It may not be aligned right using the pin & holes, so go by whether the solenoid actually lifts the valve, a ball bearing pushed by a rod on mine, a spool valve, the rod, on yours!!!!! Line up the inner splines on the 2 pieces by sight, then with the main-shaft before bolting it together to compress the springs! Also, don't use STP as lube for the pump's cam & roller! it will skid & wear them out! Very surprised by ALL the sludge, then again mine was only 5 years old. Good Luck.

Quite complex. Looks interesting

mine is a J type... i hope to never open it up.
