Manual PTO adjustment tools?
 

I realized the other day when I rebuilt my 128 PTO, that I had forgotten it took a special cut tool to adjust it correctly to OEM specs. It just so happened that I found the one I got years ago to adjust WF PTO's. I am just curious where any of you out there, get your adjustment tools for WF and NF PTO's? I am going to need one for a NF in the near future. If anyone had access to a water jet or some other similar piece of equipment, I have mine that you could use as a template.

the one you have pictured is for a NF.

Uh oh!

This is not good news, LOL. Someone lied to me years ago. Well I guess the PTO on the 128 will coming back off, altho it seemed to adjust pretty dang good. Tho I am not close to see if it will actually release using the handle. grrrrrrrrrrrrrrrrrr I've probably ruined the springs! Once again, thanks for your knowledge and help.

Boy, you got me thinking now..... I'm going to need that tool soon too, and I also had forgotten about it... We used to have one.... Hmmmmmm. I'm gonna have to go digging.

My pto rebuild kit came with one. I actually got one with more than just the clutch disk, it came with the bolts, jam nuts, and springs. I would like to see a kit available that comes with bearing and locking collar and all the set screws too. i know I would buy one just to have around

LOL, well you just missed my for sale post a couple of days ago, of all of that. My uncle had bought a complete PTO WF Heavy duty kit years ago and gave it to me, but, it is no longer for sale.

I'm wondering how much of a difference there is with adjustment between the two different tools. I'll have to take a pic of my PTO with the tool installed. As a matter of fact I'll go out and get one. :)

Hold on before to get too wound up.

My first 125 come with a WF PTO. It been working fine for years. See if you have the 6 bumps (WF) or smooth (NF) PTO pulley.

Some pics of the tool and PTO. All the ends touch precisely from the outer PTO edge to the center of the flat springs.

The three fingers are slightly above plane.

Using the wrong gauge results in too tight a spring setting, the correct one is 3/32 less in height.

Thanks. Guess I'll see if I can find a WF tool. :beerchug: Will pull the PTO back off tomorrow and see if the springs will come back flat till I can get it right.

What about making one :bigthink:

Good luck,

Last time I needed one I did my homework and ensured I got the NF gauge for a NF clutch, then posted a WTB ad on the forum and someone mailed me one. They make all the difference. I tried fudging it without one before and it 1) slipped and 2) I almost lost a throwout lever because the nuts came loose.

I'll probably post in the wanted section after I make sure my local dealer doesn't have one tucked away somewhere in his garage.

I don't have to tools to make one or to fit perfectly. The one I got looks to be stamped from thin stainless.

Here are photos of both gauges. The narrower gauge is for the Narrow Frame, which has the springs with the bent tips (kit 759-3490).The wider gauge is for the Wide Frame with springs with flat tips (kit 759-3489). On the superimposed photo you can see how the Wide Frame gauge will cause the center wear button to be 3/32" higher, and thus less spring tension.

I've had problems with the flat tip springs on my Wide Frame, so I used the Narrow Frame kit with the proper gauge, and it has worked fine for years.

If you want a Wide Frame gauge I can mail you my extra gauge, just reimburse my postage.

So you are saying you used a NF PTO unit instead of a WF? I've never really had issues with the flat springs, but I do like how the NF springs fit into the NF outer plate better. I would be more than happy to pay you for any charges and adjustment tool. I need to have one on hand for future use. I have another WF PTO I plan on rebuilding too. :beerchug: I'll PM you my info.

About ten years ago I had to rebuild my PTO clutch on my 149. I recall the center wear button was worn out. So I got the wide frame kit and afterwards I couldn't get the fingers and springs to stay in place for more than a few minutes of use. Maybe my bronze button was hitting off center and causing the steel button to knock one of the three fingers out of the groove? So after going through two wide frame kits I decided to try a narrow frame kit.

What I found is that the bent tips of the NF kit springs helped to keep the three fingers and center button in place. These bent spring tips cannot go any further than the inside edge of the PTO pulley, but the flat tips of the wide frame springs can slide across the top edge of the PTO pulley.

The WF gauge will be in tomorrows mail to you.

Thanks again Roy. :beerchug:
