Can any one tell me the best way to prime oil system after complete rebuild.new crank,cam.oil pump,pistons,sleeves,head job,mo monet mo money lol
 
It"s in the archives somewhere. But, basically what I"ve done is put I beleive it"s a 7mm socket or something close to that on an extension on connect it up to the oild pump allen shaft through the distributor hole; hook that a drill and pump away until the oil filter fills up then you can turn the motor with the starter while you"re drilling away and it will lube the entire system.
 
I took a piece of 1/4" hex rod about a foot long, chucked it up in my cordless drill and inserted the other end down the dizzy hole into the oil pump. Drove the pump that way. I got oil pressure, but no oil up to the rocker shaft.

I'm not sure it did much good, but that's what I did on my 660. YMMV.
 
Fill oil pump with assembly grease or vaseline.Pump it full.Do this before replacing pan. I always use black assembly grease but old timers used vaseline.I have forget to do this and I removed oil line at block and used a oil can and pumped oil to fill pump.
 
There is absolutely no need to put grease, vaseline or anything else inside the pump. As the others have said- remove the distributor and use a 1/4" socket on an extension to spin the pump with an electric drill.

Oil for the top end of that engine gets there through the center cam jurnal.The engine needs to be turned to get oil up there.
 
Find a vessel you can pour oil into, that is stout enough to be charged with 100 p.s.i. of shop air. (like an old propane tank). Install a TEE with a valve downstream of it so the tank can be pressurized after it is filled with oil. Run a hose from the valve to a gallery plug on the motor. Invert the tank so the valve is on the bottom, open it and the motor will be primed in a few minutes. Close the valve as soon as oil shows on the dipstick (oil sabre for you Brits) because it is not desirable to let the tank go dry, as this will blow out the oil you just put in there. This setup is also useful for changing turbochargers, as it negates the messy, tedious and time consuming job of trying to prime the turbo by hand.
 
on your tractor, the drill is the easiest.
on tractors where this isn't possible,
take the plugs out, jack up one rear tire,
put it in high gear, engage the clutch and spin the tire.
(saves wear on the starter....if there is one)
just did a big green tractor this way,
quite a workout, but got full oil pressure
 
The engine assembly lube is the best way to prime pump when you rebuild. I worked for a Cat Dealer for 34 yrs and we always did this on all large construction equipment.It's will pick up pressure as soon as engine turns over and save engine $$$$$. We used the white assembly lube,same as black just has moly.
 
I always assembled the engine with a combination of STP and motor oil - sticky enough to provide lube and cushion until the oil pressure came up. Learned once the hard way not to assume a new dry pump will prime itself, so the oil pump always got primed with some of the same stuff. Usually cranked the engine some with no fire to make sure everything is mechanically kosher, then light it off. Never had a problem...

hy? :?:
 
when using the drill method (or the pressure tank) also slowly crank the engine over by hand until the rockers start to get oil, there is a cross hole in the cam that only lines up at one angle find that and then run the drill for a bit...
