Remove 140 belt pully unit?

Red Whiskers · Jun 7, 2013

Just bought a 140. Will be using the PTO but not the belt pully. Can I just remove the whole belt pully assembly and put a cover plate over where it is?

Yes you can remove the belt pulley but you will need the cast cover to put back on. Its just a square plate that bolts on after removing the pto it covers the gear and keeps the dirt from getting in there.

Why? The belt pulley unit in not in the way and you can use the PTO safely without removing the right angle drive. All attachments and implements were designed to work around the belt pulley . . . and you just might need it for something one day.

You can remove it but you will need to find a cover plate. A flat plate won't work because the shaft extends beyond the mounting surface. You might as well just leave the assembly in place. However, when you remove the pulley that Watson there for your Woods mower, you must install a sleeve with retainer bolt over the splined shaft that the pulley was on. The seal on that shaft runs on a bushing, not directly on the shaft. The pulley or the sleeve must be on there to keep the bushing in place. If you loose that bushing, you will have a serious transmission oil leak.

Was supposed to say was on there, not Watson!

Really? Uh-oh. I didn't know that when I pulled the belt pulley when I switched from a belt drive Danco C-4 center-mount to a PTO drive pull-behind Bush Hog. That was 1993 and no problems yet. (The Case IH dealer said I got the last cover plate East of the Mississippi.) Should I pull the cover and look for the bushing? Where would it leak from?

You definitely need the cover plate with the little dome. The shaft sticks out too far for a flat plate.

No, you don't need any sleeve or bushing when you remove
the pulley gearbox and install the cover. I was talking about if
you remove the pulley from the splined shaft on the gearbox
but leave the gearbox in place. That is when you need the
retainer sleeve. There is a spacer sleeve that can be installed
in place of the drive gear that is on the tractor shaft that you
covered up with the domed cover. If anyone ever wanted your
old belt pulley gearbox they might need that gear that is on the
tractor. That is because tractors that had PTO but no pulley
came from the factory with a spacer on the shaft and no gear.
Those domed covers can be found at salvage dealers.
Surprised you were able to get a new one!

Thanks, now I understand. The cover was NOS, and had been sitting at some IH dealer in Maine for ages. My NJ Case IH parts guy was quite proud he found it. Price was quite reasonable, too. That was 1993, and the internet had yet to become a force in finding tractor parts. I would not have known how to find a used one back then.

Besides the one in Maine, I think there were two in the Pacific NorthWest, period, end of story.
