oil pump and pressure

Unknown

I have now surrendered the gear pump which was retrofitted to my car

and I am in the throws of making some internals for the original. I

suspect that the previous custodian changed the gauge to one that

would cope with the gear pump. It reads in PSI up to 80 lbs. This

unit is unlikley to register the performance of the original pump so

can anyone help in sourcing a servicable replacement or advise as to

what pressure the pump should deliver so I can try and recalibrate

the present one. I have a similar system on my 1913 which has a gauge

reading 1 to 4 but 1 to 4 what I do not know. I merely have messed

with the spring until it reads 2 running and all is well. The gear

pump provided so much oil that a good two pints per hour fell out of

the rear main bearing, making it a very tiresome and expensive Gordon

Bennet Centenery rally in Ireland last week.



On another note I found a 1919 engine and gearbox over there running

a saw bench and hope to complete purchase of the same later this

month.
