Stuck Armature...need help!!

[R65Singh]

Hi All;
I am working on replacing the timing chain on my bike and following the instructions and precautions posted by other members.  I am stuck at the point that the armature (rotor) wont slide off the crank shaft.  I have used 3 prong puller but not sure how much force should i apply without damaging something.  Is there any thing I am not doing right here?  I thought better to ask you experts before i do something stupid...
Also i re-lubed the splines on the transmission and noticed that the input shaft only go about half of the length in to the clutch side...is this normal?

There is a simple tool to remove the rotor, it's a long bolt, with about 1 inch of threads removed, I think it threads into the rotor, and then bottoms out in the crankshaft, as you tighten it up, it pushes the rotor off, more like it pops off .

The tool is made of hardened material, I don't think a regular bolt will work .

Check out this vendor.  http://www.northwoodsairheads.com/Tools.html
The alternator tool is what you need.  I bought the exhaust nut wrench  (aka Fagawi war club) from the guy and it is much better than the cast pot metal job that so many stores sell.  He has good stuff.

The simple tool from Northwoods is the way to go. Be sure to follow the instructions he sends with it. You'll only snug the tool up and tap the end of it with a hammer, and the rotor will pop off. (Be ready to catch it!).

I just stumbled across my home-made removal tool, and used it successfully to remove the rotor from my broken engine over the weekend.

You only need go to the hardware store and buy a Grade 8, 1/4" 4" long fastener, and cut it to length.  It slides in the hole, and then you use a Grade 8, M8 x 40mm fastener to do the "dirty work".

Here are the instructions telling you how to make your own, and the principle upon which it works.

Hint: Use the authors' idea of cutting the bolt at the hardware store.  Those hardened bolts are tough to cut with a hack saw!

Thank everyone!!! It it out for now.  I used the instructions from the site Rob pointed and it worked out perfectly.
