Re: info needed about a 332.....
Tony, You may have 2 different problems.
1. You're saying the bearing is frozen. With engine not running and pto switch "off", you should NOT be able to rotate pulley...it has a "brake". With engine running and pto switch "off", pulley should NOT rotate..."brake" prevents rotation. Bottom line, if pulley does not rotate with engine running, bearing is OK.
2. As far as pto not engaging: could be bad pto switch, bad/shorted wiring, bad pto coil, or a bad safety switch, or even a bad TDCM. First things first: Disconnect wire from pto. Start engine, turn pto switch "on" and check for 12v +/- at pto wire. If voltage, check ohms through pto coil...should be 4 ohms. If ohms...3.6 (??) to 4.0... good, check ground...from pto housing to frame. Also, check pto gap, .018.
Start there and get back. Bob
