7. 35 to 75 psi to all crosshead pin bushings and crankpin bearings this special gear pump is driven by a bolted on drive shaft Driver is made with a female drive square which drives the male square end of the lube oil pump shaft The driver shaft is piloted by the main bearing inner race cone and is secured to the crankshaft by four socket head cap screws Stake their heads using a center punch to upset the adjoining metal The lube oil pump Tuthill is a gear type pump possessing a self reversing sector which automatically switches suction and discharge connections in the event that the pump is caused to rotate opposite the correct direction The lube oil pump is readily removed for inspection repair or replacement without disturbing any other pump component The lube oil pump shaft is journaled in a bronze bushing fitted into the bearing carrier If this bushing becomes worn it must be promptly replaced A worn bronze bushing will cause this pump to frequently lose its prime and also may cause excessive wear in the pump rotor teeth DISASSEMBLY After removing the connecting rod cap and cap bolts note identifying marks on each cap so each may be later correctly reassembled onto its own rod remove a bearing carrier from the frame Two jack out tapped holes are provided in the flange of the carrier for this purpose Support the shaft during removal to avoid damage The crankshaft may now be extracted once all con
