Gleaner M2 Injector pump

[Toolgod]

I have a M2 I need to pull the injector pump out and need help.
On the gear side there is a center nut and then 4 bolts around it.
Do I just have to remove the center nut? Then remove the bolts from the pump side
to get it out?
Thanks for the help

I believe you do not need to remove any inside the gear cover, time the engine and remove the bump, the shaft and gear stay in the engine, you will need to replace the two umbrella seals on the pump shaft and be very careful not to roll the seals when reinstalling the pump

If it's the DM pump, LEAVE THE SHAFT NUT ALONE! remove the four gear bolts after timing is set, then remove the gear, then you can get to the pump mounting bolts from inside after gear is out. The DM pump DOES NOT have umbrella type seals like DB,DC,JDB AND JDC pumps have.

Thank you @Dieseltech I do not know all those roosy pumps, just done a few and all I have done have had the seals, I appreciate the information

Ok yes it is a DM pump. Is there any service manuals for the DM pumps or are they the same as the DB?
And Thank you .

Had bad fuel in it. Cleaned tank, lines and can not get fuel to injectors. Any way to flush it or jut tear apart and clean and reseal?
Thanks

The DM is the heavy drive version of the Stanadyne/Roosa pump line and needs some tools that are not use on other pumps.

Any place to buy the manual for the DM4 pump?

Sounds like the fuel shutoff linkage inside is just gummed up an stuck maybe
Usually pull the top cover an free it up if it's the pump I'm thinking of.
Picture of it handy?

Checked that and cleaned. Found the manual.

That's if he's LUCKY, Good chance the rotor plungers are stuck from setting unused awhile.

Guess I've been extremely lucky cause have gotten a dozen or so going through the years freeing that up.
