eldorado 850 oil pump gear wont pull off

[Eldo73850]

I am at my wits end i am trying to get my oil pump gear off my 850 eldorado im restoring the entire thing and that damn thing wont come off for nothing i have tried all different pullers and even have bent a few any ideas?

did you try removing the key?

[Eldo73850]

I dont even see a spot for a key its the very bottom gear of the three in the front

I guess the question is how do i remove the key when i cant see it or even access it if its where i think it is the little tiny notch

If you look at the gear where it slides on the shaft, there should be a key that holds the gear from spinning. The shaft and the gear should be slotted for the key

The key should be in that tiny notch, hopefully it's not banged up to prevent easy removal.  Is the gear tight on the spindle or loose?

The earlier bikes had a tapered shaft and you can't see the key. Later bikes were a straight shaft.

Have you tried heat?

The key is a Woodruff type. If it rotates in the shaft the corner may hang up in the gear keyway.

My standard cure for this is to get my 3-jaw puller on it tight and then pop the shaft of the puller with a smart blow from a 'live' hammer (not a deadblow -- I like a traditional ballpeen).  If it's nice and tight and you pop it smartly, the problem becomes catching the stuff before it hits the floor.

If the key has become bound this will be more of a challenge.  Someone asked if the wheel is loose or tight on the shaft . . .  this is an important detail.

     Could be some Einstein put red loctite on it at assembly. A burns-o-matic should not get things too hot to hurt anything, but use your head. Had some fool do this to a tapered pump shaft on a JD combine. Swearing seems to help too.

Even worse, the green stuff for cylindrical bonding. I agree, though.. heat it to 400 and try pulling it again.
