Just got a new-to-me/used series 300 PTO clutch off of the auction site, arrived today. Long story short, I have a good field coil off a 300 series tractor that bolts right up to my 69 140 H1 Kohler engine block and works like a charm when energized. I plan on putting everything forward of the field coil from the old 140 PTO Clutch back on but there is a hitch. Slight binding when I try to put the key into the crankshaft slot and when I try to install the part that fits over the field coil...doesn't want to make a nice, smooth slip fit. The key fits into the crankshaft slot and slides freely back and forth, but won't slide right out of the end of the keyway on the crankshaft. It should, right? Don't want to be hammering this stuff on, so what's the best way to burnish/clean the crankshaft, keyway and other parts until I get a nice, smooth fit that doesn't require a hammer? That is what I want, right? Can't imagine trying to key the part that fits over the field coil back on and then beat it on. Should it fit down on the crankshaft until the key bottoms out in the crankshaft keyway, so that the field coil is basically entirely covered up? Thanks in advance.
