Do any newer Case tractors have internal pto slip clutches? The reason I ask is I was using a snowblower on a 110c and the snowblower stopped and it made a sound similar to a slip clutch. I just figured I sheared a pin on the snowblower. Cleaned snow out of blower and started back up and it worked as should, no sheared bolts. So what caused the blower to stop without a shear pin going? Never heard of a internal pto slip clutch. There is not a slip clutch on the out side of the tracto pto. Any thoughts?

Good Morning darwin.wollman, welcome to the tractor forum.

According to tractordata.com your tractor has an independent rear PTO rated at 93HP. See attachment below:

An independent PTO utilizes a hydraulically actuated clutch pack to drive the PTO shaft. To my knowledge, there is no slip clutch or other safety device in the PTO drive. I would check to make sure of the proper shear bolt in the snowblower to prevent damage to the tractor's PTO. If the shear bolt is correct, then you should check the actuating pressure of clutch pack.

Your tractor have the two speed PTO ?
Was not uncommon for the internal shift fork to be mis-adjusted or for the mechanism to be damaged from improper swapping of the PTO shafts by the operator

It sounds like your internal pto clutch pak slipped, as has been mentioned checking the operating pressure of the pto activation system would be the first step.

From what I know of the 110c, regardless of which version or transmission option the PTO is strictly mechanical. A dry clutch plate mechanically applied with a lever and a control cable. It's entirely possible that this could slip under heavy load if the cable needs adjustment. Typically the lever to engage the PTO should have pretty stout resistance. The harder the lever pulls up, the greater the pressure on the clutch disc. If you can pull it up with just a little effort, you should probably make that adjustment. It's on the lower end of the cable where it attaches at the clutch housing.

The type you are talking about is a second set of release fingers on the flywheel clutch (Two stage clutch) -- the cable adjustment should be treated just like the main traction clutch (must have some free travel)
Pressure on the clutch disk is provided by the springs in the clutch plate -- the lever was used to release the clutch , and must be stored in the down position, when the PTO is not being used

Pretty sure the "C series" used a hydraulic clutch pack for the PTO and a single stage traction clutch

There were Standard, Pro, and Deluxe models of that tractor line, which makes figuring what options that are on a model difficult without actually looking at the machine

One would need to ask if there is a lever to lift and lock, then a second lever to "put the pto in gear" or a Button on the console ?

Same for the hydraulics -- open center valves, or closed center valves, or closed center valves with standard gear pump

 

[LouNY]

There are several 110C tractors is it a CIH 110C, or a Farmall 110C or ????.
I would have thought that all the 110 units would have been using a multi disc wet clutch for the pto.

Really need a description of the controls that operate the PTO from the OP
that would clear some of this up
Pictures would be even better

And, does this tractor tractor have the dual speed PTO ?
need that clarified also
