Oil Pump Primer

[kevsvette]

I got a Summit 901010 Oil Pump Primer for X-mas & it seems i've already broken it :lol: . Actually it appears that its missing a pin that holds the lower sleeve that slides over the tang that fits into the oil pump.

I got a stupid question though ... I know the upper blue piece fits over the distributor hole but what's the lower blue piece for above the sleeve?

I assume it needs to spin clockwise & should probably take the valve covers off to make sure that the oils made it up to the top of the motor. Is it necessary to rotate the engine?

That lower portion of the oil pump primer completes the oil passage thru the block. Without it the primer would only pump oil to one side.




Below is a picture of my MSD 8360 without the gear installed. It has the same shape to complete the oil flow to the other side of the block.

ALL electric drills WILL eventually run into over heating issues spinning a oil pump primer because the torque load that results causes the drill to spin at a fairly high load and LOW rpm, resulting in a good deal of resistance and HEAT but not much cooling air flow thru the drill.
the simple answer is to braze a deep well socket to the upper end of the oil pump primer tool you make from a distributor or purchase than spin it with an air ratchet , which won,t result in a drill burning up its motor

Indycars is correct that part forms part of the lifter gallery oil passage wall, if its missing youll have very low oil pressure, as the oil just flows to the point of least resistance which without that is the area around the distributor base

that idea of the preluber depth limiting collar you added ON A COMMERCIAL OIL PUMP PRIMER

most of the decent functional oil pump priming tools tools look like this

but keep in mind THOUSANDS OF THESE TOOLS that are basically worthless ARE SOLD

welding a 3/8" drive deep well socket,

or thread rod nut,

to the upper end of the primer tool makes use of an air ratchet far easier

the upper flange is designed to maintain proper alignment with the oil pump drive,
the lower spool forms much of the lifter gallery oil passage wall,
I obviously don;t know how fast the priming tool is being spun,
or how much torque is applied to the oil pump drive shaft.
but if you spin the oil pump drive continually , and reasonably fast and remove all the spark plugs temporarily,and
have a buddy with a breaker bar on the crank damper bolt slowly manually rotate the engines rotating assembly oil should exit all the push rods
if it does not you may have left out a oil gallery plug
use of an air ratchet saves considerable strain on an electric drill,

most electric drills rapidly heat up and some fail under the stress/resistance.
your better air ratchets remain un-phased
or you can go old school
and modify a brace to accept a manual connection to the oil primer tool....
been there done that regularly,
as it allows you to feel the oil pump build pressure

check yard sales, a brace drill costs over $125 NEW,
but frequently costs under $20 at yard sales and flea markets

verify the oil priming tool's spool distance, diameter and the upper and lower bands on the tool that form the oil passage walls from the end of the tool compared too the OEM distributors measurements
(look at this picture POSTED BELOW)
if your spool is incorrectly located,
theres sure to be a significant loss of potential pressurized oil.

I can see a few oil pump primers, made from old distributor bodies, that might not have the necessary length to allow its use.

IF your engines hard to prime, check your primer tool, measure the diameter of the tool and height of the lower two bands on the tool compared to your O.E.M. distributor , compare the two, a 12" caliper is almost a mandatory tool to own in this hobby

verify the oil priming tool's spool distance, from the end of the tool compared too the OEM distributor

BEVELS IN DIAGRAM ,ON THE BLOCKs DISTRIBUTOR MOUNTING HOLE ARE GREATLY EXAGGERATED FOR CLARITY, YOU CAN ALSO USE A 1/8" RADIAS CURVE
if your distributor uses O-rings you should use at least the upper o-ring, as the distributor base with O-RINGS is sometimes machined slightly smaller in diam. ...a 1/8" wide 45 degree bevel with smooth rounded edges is preferred .....notice the MSD distributor BASE posted previously ( SEE PICTURE AGAIN BELOW) has the O-RING grooves

HERES INFO ON BUILDING A PONTIAC OIL PUMP PRIMER TOOL
http://butlerperformance.com/i-24452907-butler-pontiac-oil-pump-primer-shaft-bpi-039p.html
remember that you spin the drill or air ratchet on the pontiac oil priming tool in reverse (counter clockwise) of the chevy direction (clockwise)on a Pontiac!

Id suggest you visit a local salvage yard and find and purchase an older pontiac distributor and fabricate your own tool
braze a socket to the upper end of the shaft and you can use an air ratchet too spin the oil pump priming tool, and avoid burning up a drill.

I never tried the chevy oil pump primer tool in dual use situation,
(I never thought to try it) (priming a pontiac V8)(or a buick or caddy)
I simply fabricated one to use in the PONTIAC, BUICK, CADDY) engines, I built , the same way I did for CHEVYS,
in that I fabricated one using a used pontiac distributor,
I got dirt cheap from a local salvage yard as the basis for the priming tool

Oil pump priming

I have attempted to prime and pre oil the system in my 355 build using the tool shown on Grumpy's stickys but am not sure if all is as it should be. The filter was filled pre installation and the balance of the 5 quarts of oil poured into the lifter valley. The tool in inserted and run with a...

Melling MPL-201 Engine Oil Pump Primer

Melling Engine Oil Priming Tank was developed as a way for engine builders to safely pre-prime the engine with oil prior to initial engine startup. The priming tank, when filled with clean oil and air pressure pumps oil into all of the critical areas of the new engine quickly and safely.

www.speedwaymotors.com

https://www.melling.com/videos/how-to-prime-engines-and-oil-pumps-by-melling/ melling sells a pump pressure tank for about $270

HF sells a pressure tank you could very easily use after minor conversion for $100

2-1/2 gal. Air Pressure Paint Tank

Amazing deals on this 2-1/2Gal Air Pressure Paint Tank at Harbor Freight. Quality tools & low prices.

filling, and pressurizing the internal engine oil passages, and changing oil and filter with fresh oil is a good idea,
as is pulling the spark plugs and squirting a few tea spoons of MARVEL MSTERY OIL into each cylinder before ,
you initially spin the engine a few times and only then replace the spark plugs and reconnect the ignition wires before you start the enine the first time
but there are much easier and cheaper routes

I wondered about the grooves, but the MSD manual never mentions an O-Ring, not even once.

Every day is a new adventure !
