Replacing the PTO pad advice

[Wheelhorse#1 1,667]

Is it best to remove the rivets and  silicone in place ?

How do you do it ? thank you

Timely post.  My PTO clutch appears to have developed a terminal case of the slips today - it couldn't keep the deck blades up to speed in heavy grass.

 

Can I ask what supplier you got the clutch facing from?  Also, how thick is the new facing?

 

My thought for attachment would be a high temperature  resistant epoxy.

 

Thanks.

Hello 

I sent you a message.The thickness was 1/4 but looks thicker than that to me.I’ll measure.Disk size is right on the money.

 

Is your  

PTO pad worn off completely or below the rivets ,Did you try adjust tension?.

My calibrated fingertip tells me that the rivet heads are about .015" to .020" below the friction material.

 

No more adjustment available on the PTO engagement rod.  Turns out that there is some wear in the clutch lever pivot holes, too.  Planning to install some oilite bushings to tighten that up.

@8ntruck, note first picture , looking down on ground rail along side battery , look at the teflon and steel washers I  added to tighten up that sloppy lever , also while you are in the area, look at the last picture , see the 4 ga cable going to engine / frame area ? hook that up to the battery ground rail , 1st picture , to really help ground issues , really helped me out , pete

 @Wheelhorse#1  I found my PTO problem today while I was cleaning the bell.  The outer C clip on the stubshaft that the clutch arch pushes on had come out of its groove, effectively taking about 1/8" of travel out of the engagement linkage.   One of the ears on the C clip is broken off.

 

Back to the hardware store tomorrow for a new C clip.

@papaglide, typically find related areas to help out while i,m in the area , also added a 2 bolt flange bearing to the upper end of the steering column , note elastic nut on top of bolt to rear of battery / dash area. when I find an improvement that works , I  add it to my other 2 horses , so that they all have the same set up . if you have a nagging problem , that's the  best opportunity to get after it. regularly go over my horses for anything , like to keep them bombproof in operation. that electrical grounding issue , while simple was a major upgrade in my running / starting , pete

If you look close at the clip you will see one side has rounded edges and the other side they are sharp because they are stamped when made.

When you install the clip place the sharp edges to the outside for a better grip in this application.

If your stub has a clip inside the bearing that one should have the sharp edge facing in.

Yup.  I know that.  Only thing is, i didn't pay attention as to which side of the clip was facing out when I put it back together yesterday. 

 

50/50 chance I got it right.

I have been there a few times with the C-clips coming out in the last 44 years. I have also replaced the short shaft a couple of times when the groove was worn too much.

I try to keep a supply of C-clips, hair pins, bearings, and other part in my parts bin. Saves a lot of trips to get parts when you need to been getting the job done. I have also 

found most stores don't keep up the supply in the parts drawers.

  I put it back together with a with a roll pin holding the stub shaft bracket to the arch.  The store didn't have a Spirol pin.

 

Somehow, I don't expect that roll pin (probably an import) to last very long.
