having trouble removing disc drum. Do the puller jaws go in the round holes on the outer diameter or do they go behind the casting. I do not have the proper puller just regular pullers. What the secret?
You need a pretty hefty 2 arm puller, and lots of Kroil or other good penetrating oil, let it soak some. Insert the puller grab arms into those holes.
The proper puller goes into the holes from the outer diameter. Any other puller could probably grab anywhere that's convenient. The secret is to pull like hell. A little heat wouldn't hurt either but don't go nuts as these are all heat treated parts.
Norman : With the two bolts you have double the force
Oh..forgot the other secret tip, a big sledge to hit that puller screw after you lock it down, that will shock things loose
Wear eye protection.
Be sure to go to the bathroom before you start. Occasionally, they let go with a BANG. If you're not ready for it, you may be changing your shorts.
Its off! THANKS everybody. I turned my puller jaws around like in DAN's photo to pull from the inside, Used penetrating oil, a little heat. And a big hammer on the puller screw when it was under GREAT pressure. It was not a big BANG but it did pop a little. It fought me for about 3/4" then surrendered.
PS two of the triple gear bushings are stuck on the shafts and those gears are really sloppy the other one came out with the gear and I could push it out with my fingers and it was not near as sloppy as the other 2. THANKS AGAIN
