Darracq crankshaft
The crank is made from solid, and is nearly 1 metre long | ||
Darracq crankcases | ||
Upper crankcase has a longitudinal oil gallery,
just visible at the top of the righthand hole, this squirts oil horizontally at the bigends.
The crankcase is in a tray ready for flow testing,
I need to determine what delivery pressure is required for the the squirts reach the crank.
The oil pipes along the top deliver oil to the three main bearings and to two drip holes for splash lubrication |
