Do a search in this forum; click on 'Search' near the top of this page. There's a thread with the title: Help!! Trying to remove 81 injection pump sprocket
Lots of ideas there. Good luck!

When I took mine off, I was able to pry the gear off the shaft by wedging a large screwdriver between it and the casing beside the engine.

Screwdriver wedge worked for me as well - with some gentle taps from a rubber mallet.

You have to buy or make a puller..... look at the home made tool section for an excellent dyi welded puller. You can buy them at any auto supply store.... just make sure it's wide enough to pull on the out side of the pulley.... (three arm pullers are better for the gear)

It's a good investment.... you'll use it on the camshaft pulley some day, or the ball joints, or a battery terminal, or the steering wheel...

Not bad for 20 bucks !!

I used the type of puller you thread bolts through(always mix the types up), a couple washers, and nuts to fit the bolts.

Glue, solder, weld, epoxy,or whatever the washers to the nuts. Make sure the washers are larger than the two small holes of the sprocket. Feed the nut/washer combo through the large holes-magnetic tool helps-and slip them behind the small holes, tighten the bolts in. Loosen the nut on the IP shaft, but leave it on to protect the end of the shaft -make sure the puller won't hit the shaft when you use it.

WARNING!

you may have to replace the nut after the puller is done with it (ask me how I know)

The puller does the work, tighten in small amounts while tapping with a rubber mallet.

Should pop off-good luck

I got a generic 2/3 jaw puller at my local auto parts store. I use it in 2-jaw mode and hook into the 2 small holes in the sprocket. Some of them are stuck on there real good, I just about broke my puller on the last one but it did finally go.

I have pried off sprockets with screwdrivers before, but I worry about damage to the internal bushings/bearings in the pump.

Despite the fact that I have several pullers, my usual first step is as follows. I loosen the nut a few turns, but leave it on the shaft. Next I take two large flat chisels and tap them one on either side of the IP sprocket. I apply a bit of tension that way, but distribute it evenly by placing them opposite each other, or close to it. Then I take a pointed punch and place it in the center of the injection pump shaft and tap it sharply with a hammer (not beating the crap out of it, but some good sharp taps). That almost always pops it off, and is faster and easier than fussing with a puller. There is not really any stress being placed on the injection pump, as all of the force of the hammer taps is sent to the sprocket and then to the chisels and to the engine block. The reason I leave the nut on the shaft is so that when the sprocket finally pops off, it doesn't go flying, land on my foot and get dented on the cement.

GOT IT OFF!!

Two screwdrivesr to pump pressure on it and light taps with a copper hammer for about 3 minutes, and off it came!
