How do you remove the clutch drive gear from the back of the belt pully? The book said "using a suitable puller, remove the gear." I put a LARGE puller on it, tightened as tight as I could, added heat, and still no go. Any suggestions? I need to replace the dogs and toggles. Thanks, Moye

Moye, I tried heat to no avail...used a big 3 jaw puller and a 1/2" impact gun to turn it, no luck at first, so I turned it as tight as I dared, sprayed alot of PB Blaster on it, left it loaded (with pressure) went to lunch, when I came back, it had moved...impact gun took it from there easily! Pressing it back on was even more fun, took so much pressure I was afraid I would break it, but it turned out OK, had to use the big industrial press in our shop at work. Pete

Moye, first you will need a proper fitting & heavy thickness center that pilots in the pulley hub & isn't too big in outside diameter to hinder the gear sliding over it.... Then use a good amount of heat on the gear & a big gear puller. It will fight you but should come off with enough heat & pulling. Make sure the puller jaws don't touch the ends of the gear teeth & chip them [I use little pieces or aluminum to protect the gear teeth] & try to get the puller ends under the gear teeth far enough to not pull on the teeth only.
~If it still won't come off you will need to put it in an arbor press & use a gear separator under the gear to support it while pressing.
~When re-installing that gear put a support under the pulley center hub, if you try to support in only on the pulley rim you risk breaking the pulley....

Thanks, Cloony. I have done exactly what you said. Guess the next step is the machine shop and their big press. Thanks, Moye
