Need a little help with clutch removal

Last week when I was researching the topic of removing the clutch off my McCulloch TimberBear I came across a picture of a piston (don`t remember the make of chainsaw) with a hole towards the center caused by a metal piston stop - thin metal in the piston.

I chose to use a 1/4" braided rope and pushed in about 3" towards the sides (sides are the stronger part) of the piston as the piston was coming up in the direction the clutch nut will be removed (clockwise on the timberbear) and then the clutch was suppose to slide off except it was gummed on the axis forcing me to build a clutch removal tool like some of the tools described above to break the glue-like gumminess.

Rope worked both times for me to stop the piston to remove the clutch nut and then the gummed-on clutch.
 
Okay, a picture of my 5-10 minute wrenches. This one was for the Husky 350 and was about a 5 minute job because it was only a two tooth. The one for the 372 took much longer because it was a 3 tooth.

There is a hole drilled through the top through which I stick a phillips screwdriver which you can sort of see from this angle.
 
A bench vice will work to get that clutch off. Tighten two bolts in the vice just far enough apart so they fit between the clutch shoes grab the whole saw and spin the clutch off.
Rope works excellent as a piston stop.

Thanks for the idea. Don't have a bench vise, but was able to clamp the two bolts in a vise-grip plier, then turned it like a wrench.:clap:
This after trying the hammer/chisel method, thought I would break something. Can't believe I hit my beloved 350 that hard.:msp_mad:
Also used the rope.:msp_thumbup:

Did the trick.:cheers:
