brazing screw up?

Postby grumpyvette » September 30th, 2009, 8:36 am

" I know recommended oil pump pick-up to oil pan clearance is 3/8" to 1/2"
I took my pump and pick-up to the machine shop to get brazed and when it came back it has about 1" clearance to the oil pan, floor. This is a street car that will have very little strip time. I have 2 questions.

1) Will this cause any detrimental effects to my oiling system? Pump cavitation, loss of oil pressure?

2) If so, what are my options besides buying a new pump and pick-up????"





you can, and should re-heat a brazed pick-up that's not correctly indexed very easily with an oxy-acetylene torch and then tap the pick up to the new location, (rotate it slightly in the pump body) and re-braze it, that's one reason brazing is generally preferred to tig welding the pick-ups, be sure to remove the oil pump bye-pass spring during the brazing process and let the pump and pick-up col slowly in the air rather than cooling with water as that might warp the pump, then reassemble , after checking function and end clearances on the pump, and placing some Valvoline in the gears to allow the pump to prime much faster.
that's an easily fixed deal, if your not comfortable doing that the use of a new pump and starting over is minimal compared to the potential of ruining an engine with the pick-up mounted a full 1" off the oil pan floor when it should be 3/8"-1/2"


btw thats also a good lesson in WHY you need an oxy-acetylene torch in your list of tools in your garage.
