I am trying to get the 11 hp Briggs & Stratton engine out of my Toro tractor to replace the gaskets, since it is using & throwing oil over abundantly. How do I get the drive & mower pulleys from under the tractor off of the crank shaft ?

There should be a key and most likely it is a woodruff key which means there is no set screw to remove from the hub of the pulley. But to be sure that is not a square key you need to look at the end of the shaft. Use a mirror to take a look at the end of the shaft, if you can see the key then you should be able to tell which type of key you have. If you have the bolt removed, then use a 3 jaw puller to pull the pulley off. To avoid damaging the pulley find 3 metal pads or strips and place them in between the jaws of the puller and the pulley. Make sure that the pads or strips you use are the same thickness, that will ensure that puller stays straight. To help keep the puller from moving around take a string or some tape and wrap it around the jaws of the puller as tightly as you can. If you have the front end up on blocks then make sure that one of the jaws is toward the front of the tractor. If you have been able to remove the bolt in the end of the drive shaft then put it back in, but only a couple of turns, this will help to avoid damage to the shaft. Now you can turn the puller shaft aganst the head of the bolt and tighten it. Continue to tighten the puller aganst the bolt head and the pulley should start to pull off. I'll be near the computer today if you need any more help or calcification.
