I've got a crank handle for a Volvo MD2 if you need one. Hand started my MD2 for more than 10 years. The MD2 was designed as a marine
engine with humongous flywheel and compression
releases. You need the flywheel to build up inertia so the rotation will continue through a compression
stroke. The compression releases allow you to get the engine rotating with the crank. Without the compression releases, you cannot crank a diesel
. The compression is so high, you can't rotate the engine past the compression stroke with a crank.
The routine on the MD2 was to push the cold start button down, lift
the compression releases, crank the engine building up as much rpm
as I could, deactivate the compression release on one cylinder and then the other after the initial cylinder was firing. The MD2 would always start on the first try but we were never where it was even cool when I handcranked it. If you are underway, cranking the engine with the transmission
in forward, made cranking a lot easier.
