Priming an Oil Pump

[Anonymous-0]

Just rebuilding the engine on my 1965 Ford 5000 Selecto o Speed, and i was looking for tips and advice about refitting the new oil pump to ensure that it primes quickly and get pressure on first start up.
I intended to try and fill the oil pump with new oil before bolting it in place.
How can i ensure it doesn't drain out when i right the engine( its upside down at the moment) and does't drain dry between now and start up?

did you just put the motor together? or are you just changing the pump? if you just changed the pump it should be no different then the tractor sitting all winter the oil will drian back into the pan if you just put the motor together then you should have used engine assembly greese which will protect everything till you get oil preasure if you didnt use assembly greese i would take it back apart and do it right this time
i wonder how many people are actualy on this site at this time of morning

I coat the inside of the pump well with Lubriplate NO. 105 motor ASSY GREASE... If I did dot want to dig the pump out I would pour some 90 weight gear lube down the pick up tube

remove the distribitor. take an old dist shaft and remove the cam gear.

put on end of drill and stick in dist hole and engage the top of the oil pump drive. fire up drill till oil pressure gauge says 30 lbs for about 4 minutes. reinstall distribitor and fire it up.

any of the old series of ford dist shafts will work on that oil pump iirc..

To prime the engine with oil prior to a first fire is not difficult. An oil pump drive shaft from a 351w is the same size (diameter) but much longer. Stick that down the hole in the block to engage it with the oil pump. You will need a HD drill to spin it at any speed. Do hold the shaft loosely so it doesn't drop into the engine.

You can also just use a squeeze bottle with 32 oz of oil and after filling the filter with oil, squirt the 32 oz down the center oil filter hole. That will fill the oil galleries, then while they are full, spin the filter on quick and crank it until the gage reads pressure. If it's a gas engine, have the spark plugs out so it will crank easy and have nearly zero load on the bearings.

Put the plugs back and fire it up.

If this is a fresh build, there is one tip. I normally time the engine during assembly as most at TDC compression stroke when the timing gears are dot to dot. I don't believe the 4cyl ford are that way. So, the tip is to verify you are on the compression stroke when you static time it!

Thanks for all your input guy's, i should add that it is a 4 cylinder Diesel that is being completely rebuilt after having new pistons and liners fitted and the crank polished.
The Ford manual mentions about priming it prior to bolting it back into the engine but that seemed messy to me and how could i be sure the oil stayed there during the rest of the build?
The old pump is okay but did'nt want to chance it as it would be too easy to find out that i'd got a duff one.
As to the time of the posting it is 3.45pm on Saturday aftenoon here in England.
