Have you got the engine out of the car?

The oil pump can't be removed with the engine mounted in the car.

Another fine example of why Chiltons Manuals are only good for keeping shop doors propped open, or for kindling up a wood stove.

Do you have a 5 or 6 bolts holding the pump to the block?

im not a dumbass dan, haha i got the bolts and cover off and im in the process of trying to remove the cam gear and actual oil pump from the axle/rod that connects the two mechanisms.

I have tryed heating the gear and rod and tryed using a 2 hand gear puller and ended up with the puller blowing up in my face(literaly).

I do not believe it has a key way and wanted to know if you had any other suggestion on how to get the damn thing of without cutting the engine in half.

Yes the engine is out and completley dissasembled exept for the cam and the oil pump, the cam cannot be taken out untill the pump is taken out since the gear hits one of the bearing points.

its a 72 225 engine that is out of a 72 plymouth duster.

any help would be appreciated thanks

If you removed the pentagon-shaped cover plate, you're doing it wrong. Find the five or six bolts holding the pump body to the block, remove those, then remove the pump assembly from the block.
That will almost certainly have wrecked it.

so just try to take the whole assembly off at once and try to pry it off that way, cuzz it doesnt feel like its gonna come off to easily. And i dont wanna screw up the entire pump assembly.

and ya ik im replacing it anyway with a new one, engines got 200 grand on it.

thanks Dan!

It can be pulled in a 1967+ car if you do the following:

1) Chock the rear wheels
2) Drain the Radiator
3) Remove the radiator hoses from the radiator
4) Loosen driver's side motor mount slightly
5) Loosen passenger side motor mount completely
6) Remove oil filter
7) Jack up the car and put jackstands under front subframe rails.
8 ) Put a 2x4 under the passenger side oil pan flange and use jack to
lift the motor up until the passenger side motor mount is clear of the K-member spool catch...or the motor mount is loose of the 'sandwich' on 1967-1972 cars. Do not jack the motor up using the jackand the oil pan itself.
9) Remove 5 or 6 bolts using a 1/2" wrench, ratchet, etc that hold the pump to the block.
10) Using a small rubber hammer or piece of wood give the pump a 'thump' to loosen it from the engine.
11) If you have an original OEM 6 bolt pump there will be barely enough room to pull it straight out and remove.
11A) If you have an aftermarket Melling/5 bolt pump:
a)Remove the pump rotor cover bolts
b) Remove the pump cover and rotating ring (that way you don't drop it and marr the surface when removing the pump)
c) Remove pump, it will just barely clear once the cover and bolts are removed.
12) Clean block mating surface.
13) If installing an OEM pump to it's place, install in reverse making sure
to install the oil pump gasket the correct way on the pump body first.
13A) If installing an aftermarket Melling pump remove pump cover, gasket, and rotating ring. Install gasket on pump body, install pump body per reverse of above, except: Once the body has been bolted to engine, with clean hands (or gloves) install rotating ring, use a dab of grease or vaseline and smear on pump rotor and ring, especially in the 'mating cavities'/contact surfaces, install gasket and pump cover, tighten all bolts.
14) Lower car, rehook up motor mounts, radiator hoses, fill radiator, install new oil filter with a good dollop of oil in the filter before it is installed-probably good to do a full oil change at this point as well.


This is far easier with the engine out of the car...and I wouldn't do this again with it raining outside either...

UUUHH!...What he said is true. Did it twice within 4 mths.

Remove the oil pump as an assembly, not piece by piece.
Be careful cuzzzz if you're not you'll break stuff.
If you heated the rotor, you probably already have.
So you care about the old oil pump because…?

Don't forget 6A DusterIdiot; Disconnect exhaust pipe from manifold.

If you skip 6A, then add 14A; Replace mangled exhaust donut.

I didn't have to do that even with the dutra duals on the hpak duster...

You must have an exhaust hanger near the front subframe or the firewall like the stock '74's had...

If you already have the pump off the motor and are trying to remove the drive gear from the shaft,, I got a great tip from Josh S on how to do that.

get a sturdy piece of 2x4 or 2x6,, drill a hole in it so the hole will accept the pump rotor, set the pump assembly on the board with the rotor over the hole and the perimeter of the pump fully supported by the board.
The drive gear would be up..
Using a brass drift and hammer, drive the shaft through the gear.

This worked well for me,, to reinstall the gear, heat it to 450 F for 10 minutes or so,, it will slip on nicely.

I pulled the oil pump off a 74 Slant Dart and it was a son of a gun. If I had to do it over again I would get a person with a cutting torch and cut the fenderwell . Get it off and weld it back less trouble. Thanks Ron










It Aint Over Until I Win

I run into some engines where the oil pump & gasket were glued to the block with some kind of "super-sealer" that does not allow for easy pump removal.

First, I stick a pry bar between the block and the oil filter mounting area and pry... that breaks many of them loose.

If that does not work, put a block of wood onto the oil filter mounting surface and hit it hard, that applies a twisting action that usually tears the gasket in half, then rotate the loosened pump "back-n-forth", while pulling outward, to get it completly out.
