New to me Model 86
 

I finally got a Cub, a '72 model 86. She looks pretty good and with only the regular stuff for an antique that has been sitting. I got her running and driving around. I am trying to figure out what I am missing on the front PTO so I can turn the deck on and off. From what I have been able to find the clutch assembly is there but everything that attaches to the end of the rock shaft is missing. Just a broken bolt in the end of the finger. One diagram shows a wear button attaching there, another shows the same button along with a brake shoe and disk. I am leaning towards the brake shoe and disk because of the distance between the clutch and rock shaft seems to big for just the button. However the turnbuckle between the PTO lever and rock shaft did not have any lock nuts on it so it could be way out of adjustment just from vibrating there for who knows how long. How can I determine for sure what parts I need? Any help would be appreciated.

This may help you........ PTO

:Welcome2:

Welcome to OCC! Congrats on your 86! Hope to see some pics of it.

That helps a lot I didn't realize there were different PTO assemblies. Now I just have to make it through work so I can go home and figure out which one I have.

Thanks. I will have to get some of those up soon.

:Welcome2:

Congrats on the 86!

You want to look at your pto rockshaft to determine which style you have. Here's one with a brake shoe for reference.

The difference between the 2 rockshafts is the hole for the brake shoe is recessed on the shaft, where as the hole for the wear button on a non brake shoe type rockshaft is flush with the shaft. So you want to look at the hole that broken bolt is in.

Here's an example of the non brake shoe type rockshaft.

Hope that helps. :beerchug:

Is the width of the piece of flat that either the button or shoe assembly attaches to another way to tell? From the two pictures you listed the brake shoe seems wider.

Figures I would get the more expensive one. But I bet the brake lasts longer.

Thanks for the quick response and the links. Pictures say a thousand words.

I think the width is the same for the 2. If you post a pic I can tell which rockshaft you have. I have both types of rockshafts at home, and i use the brake shoe pto on my 108.
You could always switch rockshafts, depending on which style pto you want to use. As long as you can get the rockshaft bushing off so you can remove the rockshaft from the frame.

I will have to look real close when I get home to figure out what I have. Wouldn't changing the rockshaft also require changing the clutch assembly as well if it was supposed to have the brake shoe? Are the rockshaft model specific between the 86, 108 ect.?

Is it a bad sign if the belt running from the clutch pulley down to the deck is not running straight. To clarify: if you stand beside the mower and look at the belt which is running vertically between the clutch and deck pulleys it appears that the clutch is too far forward.

I mowed with it for probably 20-30 minutes Monday and everything seemed fine it just looks off to me. I have been working on a fuel tank leak and trying to get the charging system to work and have not really investigated anything yet.

I measured the pto rockshaft arms, the non brake style rockshaft arm is one inch wide, the brake style rockshaft arm is 1.5 inches wide, so there is a difference. Does your pto clutch have a thrust button on it? Either way, i would leave your pto engaged, so that busted nut on your rockshaft doesn't contact your pto clutch. Hopefully all you need is a wear button for your rockshaft. Pics would help.

Here's the link for deck belt alignment in the technical section of the website.

Here is the best picture I could get of the situation. From what I can tell I just need the wear button however the end of the rockshaft and one of the clutch fingers are damaged. The rockshaft measures one inch. I checked my serial against the PTO link and it falls into the type B clutch with out the brake assuming its OEM.

Here are some pictures of my new toy. Now I just need to figure out how to rotate pictures with my ipad!

Ouch my neck...

Looks good from here as for your pto looks like you need just the fiber button.
Fixed your pix

Nice looking 86!

Nice 86, you have there!

Nice 86! You will have fun with that tractor!

the brake parts some are nla or very expensive I just use the reg one with a button both arms are the same width the hole is the only change we have either arm or brake parts used

Thanks for the comments. I really just got the idea to get a Cub because I am an IHC fan. I have many memories around old 1066's, 806's even a 1466 with a turbo if I remember correctly. My first truck was an IDI 7.3 andI refuse to get rid of my Powerstroke 7.3.

I have been into old Honda motorcycles for years but when the kids came I decided to get into something I could do with them when they got older and bought a 66 Scout 800. It's still a work in progress but I have really enjoyed it so far. After three days I think the Cub will be another addiction. The old stuff impresses me because it was made in the U.S.A. And was made to last, not wear out so you come back to buy the same thing again. I call it my old iron habit.

nice looking 86:beerchug:
