Hi. I'm new to the forum. I was wondering if anyone knows a trick to remove injection pump from allis chalmers 180 without removing the radiator. I havent started taking it off but it doesn't look like enough room between rad and engine to get a puller in there to pop the shaft out of the gear after the lines and mounting nots are removed. Thanks for any advice.

You do not need to remove the gear on the drive to remove the pump. You just need to line up the timing marks in the window,Be sure to turn the engine in the direction it runs (clockwise from front) to get the correct timing on account of gear lash. and then remove the three nuts that mounts the pump to the front plate. Once the three nuts are removed the pump will just slide back and the shaft will slide out and will remain in the engine, and the pump is now off. You will need a special tool to hold the shaft seals in place when you install the pump again.

I have never had that seal tool, it isnt neccisary, just handy. The seals are kind of like umbrella valve seals and the rear one can be flipped inside out if your not kinda carefull how you slide the pump over it. Just takes a little care.

On a 180, take the ex manifold off then leave the lines on pump. Makes it a lot easier than trying to get the back lines off and on. MACK

If you remove the six exhaust manifold bolts, you can lift the manifold and muffler up high enough to rest it on the valve cover out of the way.

That seal tool helps a bunch + a little oil ,it just compresses the seals enough to slide the pump on , Capital Diesel in Holts Summit Mo has them for $11.50 ;

Can you get them at any diesel shop? I have a couple to do, and it would make the job much easier.

Yes Stanadyne # 13371, but I haven't seen it as cheap as above. It's around $25. We have them in stock for our customers to purchase or borrow. Ed.
