<VV> Oil Pump

[Doug Mackintosh]

When I did my '64 I used feeler gages and a steel scale straightedge to 
check:
- Idler gear shaft end to gasket surface (no gasket) (shaft should end 
.010-.020" below surface)
- Face of gears above metal gasket surface - should stick up .0025-.0045"
- Clearance between gears and inside "diameter" of housing - should be 
.002-.005"
- Gear backlash (feeler gage between the the teeth of one gear and the 
other) - .002-.008"

When I was all done, I assembled the whole thing with the gasket and 
Plastigage on the face of the gear (so it would be squished between the gear 
face and pump cover), torqued everything down then disassembled to measure 
the Plastigage.  Mine measured .002".  I don't know what the correct spec is 
for that measurement, but I do know the oil pressure has been good enough to 
keep the light off, and not destroy the engine yet at about 70,000 miles 
after rebuild (1964 Spyder).

Good luck and if I confused you with the way I explained something, ask 
questions!
