VAC Belt Pully Turns All The Time????

[gmccool]

I bought a 1946 VAC that I was told had been setting inside for 10 years. It only took a battery to get it going but the belt pully turns all the time. It doesn't matter if I have the lever in the run or non run position. My IT manual covers the D, S, LA, and VA models and isn't very helpful at all in where to start. I haven't belted it up to see if it is just free wheeling or if it is stuck in the run position. Any suggestions where to start looking???With the tractor shut off when I turn the belt pully the engine turns over no matter where the engage or disengage lever is at. Thanks Gerald

Been awhile but I think all my VAC tractor have the pulley running all the time but that is also how the hyd pump is driven for the 3 point hitch

Square headed bolt with jam nut on top of pully housing, back it off and pull the pully shaft out just a little then retighten bolt and jam nut, be sure to get the bolt in the grove on the shaft

Link is to an on-line operators manual for VA series tractors built prior 1949. Page 43 shows disengaging the belt pulley driven gear as described by VAC-14. If you have the oil pump on the belt pulley read page page 53 - 58. I didn't read all of it, there is a lockout on the pump but it doesn't show a pulley on the shaft.

all VA Series with a belly HP pump on the belt pully unit run all the time, like said you can shut off the hyd pump by turnning the set screws in on the drive/lobes ,, the shaft will still turn, the units without a hyd pump in them are slid in and out like stated here as well, they had a shaft cover to put on the shaft end for Safety hope I explained that right
