Rotor puller

[mack]

So do we have a tool available from mikes or partsmore for this?

It's just a bolt. I got mine from Fastenal. Size is 16mm X 1.5, about 2-3 inches long. Not a common size, so you won't find it at most local hardware stores.

Bolt

So what's the method, you just threat the bolt in and turn. What does the bolt hit to make the rotor ride up the threads and off the shaft?

Mack, thread the bolt in until it bottoms, then continue as it pushes against the crank and pops the rotor off it's tapered seat. To prevent the crank from turning while tightening the bolt, a long screwdriver may be slipped thru the slots in the rotor to hold it still. Unlike a jaw type puller, the bolt should remove it very easily.

It still takes some decent effort to get that rotor off using a bolt. Best bet is an impact if you have access. Another suggestion is to make sure you grease the threads of the bolt. It gets tightened so tight to get the rotor off that you end up losing a lot of the torque meant to go against the crank end (That's what the bolt is pushing against) that ends up as friction against the threads. Another suggestion is to wrap the rotor with a rag while doing this and hang on to it. I've had several shoot across the garage when it finally popped loose. It's a decent hunk of metal, so keep your shins out of the way.

And last I checked Partsnmore.. they didn't have them any more. Sounds like Cbug's suggestion would be your best bet.

I went to the local John Deere dealer and they had bolts that fit for that application.
I was a bit worried about it pushing against the end of the crank with the smaller threads in the center. So I cut off a bolt that fit in there and slotted it with a Die grinder. Then I threaded it in until it was flush to the end of the crank. That way the puller bolt will have a solid surface to act against. It is how the bigger industrial parts get pulled of tapered shafts at our Concrete plant. I figure if it works for that then it is not overkill for this if it means not buggering up the end of my crankshaft. I leant it to another Xsessive in the area and it has never returned.
Oh by the way +1 on using a bit of lube on it and yes they can pop off with quite a force if they choose to. If it seems to be taking too much torque to get it moving some raps with a dead blow or rubber type hammer may help but do not be too generous on your whalloping and damage it.

If you cannot find the plain bolt, many cheap pullers found at places like AutoZone have the same 16mm bolt in them. You will have to remove the end from the bolt and grind it smooth but they work well.

Thanx

guys. Kind of embarassed at how easy it was. Bug your measurements are correct sir.
