D-180 PTO Return

[JamesBe1 84]

I did a search on this topic, and didn't see anything, so I thought I'd bother everyone with a new thread.

I am re-installing a PTO on my D-180 after an engine swap and noticed that the PTO engagement lever likes to fall forward so that the PTO spins all the time. Is there supposed to be a return spring or something to keep that from happening?

I looked through the D-180 parts manual, and there was nothing that seemed to perform that function. I was wondering if my D-Series brethren have that same issue.

Mine does the same thing i'm working on where to put the spring so it doesnt interfere with any thing else

[JamesBe1 84]

Thanx Otrelwood. I'm glad I'm not the only one to ponder this.

I'm thinking of maybe using a short bungee along the length of the pto rod.

[otrelwood 32]

might get too hot for a bungee but if it works let us know

Same here...i looked at mine and it looks like there is some wear close to the safety switch. I thought of mounting a spring also but when the mower is hooked up it isn't an issue.

I hooked up a bungee from the front end of the pto, to somewhere back by the lever. Seems to work ok. The pto is no longer spinning all the time. In fact, it was slowly turning backwards from vibrations.

Here is a pic.

i think the spring washers are suppose to hold the clutch open. they are inside the clutch. between that and adjustment of the engagment rod it should solve the problem

[bewford 21]

checked parts manual part #'s 920245 (spacer) and 102923 (spring washer)

[JamesBe1 84]

Interesting. Since I have the tractor partly disassembled, I am going to have to go into the PTO and check the spring washers.

Assuming that they are there, do they ever go bad?

Hey guys, could be wrong but I think the return spring you're describing is the one which goes at one end, from the loop in split pin that secures the pto arm to pto rod, and the other end goes to a bracket on the engine.

Mine was missing too so I just found a spring that would do the job - I'll post a photo this evening (uk time).

Forgot to say - it's not shown on the pto schematic which is why it's had us all puzzled. I found where it goes from a photo of another 'D'.

[Trouty56 567]

That's cool Andy. I was always looking closer go the lever handle for the place to secure a spring.

Andy, when you run across it again, could you post the picture? There are way to many pictures on this site to try to hunt it down.

Thanx,

he posted it on his repost of the D in the euro section .so simple its too easy

[wheeledhorseman 579]

I have indeed included details of the return spring in my latest resto update in the Euro section but I'll include that part here as well as I know only too well how hard it is to find things that you know you've see somewhere on RS.

If you look at Coldone's walk around video of that 'D' he acquired with just 200 hours on the clock, and that's probably as close as we'll get to a factory example, in the closing frames of the video there's a glimpse of the spring and how it's fitted.

For mine I found what is probably a throttle return spring from something I've dismantled in the past and it does the trick.

Nice pic and thanks. Good info.

Thankyou Andy. The pic is a big help.

I recall that vid. I just watched it again, and I have to compliment you on your superhuman powers of observation. It almost looks like the spiraling of the spring is part of the pto rod threads, but if you look closely, you can just barely make out a spring.

I'd have never thought that wheel horse would have used the Kohler lift tab in that way. Dunno why, seems like cheating, and they usually fabricate their own parts. But if it works, it works.

I think I'll take a trip up to the hardware story tomorrow and pick up a spring.

[JamesBe1 84]

Yes, it is very simple. I searched the site, but apparently not well enough.

It's not always easy to pick out a tiny spec of information in all the knowledge around here.

[JamesBe1 84]

Finally got up to the hardware store today to find a spring for this. I bought a 5" spring. With the PTO engaged, it is pulled to about 6", and with the PTO disengaged, it is pulled to about 7". I was concerned that I wouldn't find a spring with enough force to keep the PTO back, but by pre-tensioning it, it works very nicely.

[wheeledhorseman 579]

A shiny new spring adds a bit of 'bling' to your project James.

So I guess we've all got PTOs that disengage properly now but has anyone got a photo of the PTO clutch brake?

The metal bracket with friction pad is long gone missing on mine.

The Toro diagram shows this attached to the clutch arm and I can see the holes for it but on my D-200 it was attached to a bracket mounted on the engine plate (factory I think as it is painted red).

Andy

[JamesBe1 84]

I'd be more than happy to snap a pic of mine later and post it. It is directly under the PTO attached to the PTO arm. It is fairly thin, and should be very easy for you to fabricate.

[JamesBe1 84]

It wasn't until after I sat down to upload the picture that I realized that I should have held a tape measure up to it. <Sigh>

As you can see, it is bolted to the pto engagement bar. I can take a possible better pic tomorrow if you need.

[wheeledhorseman 579]

Thanks for the pic which confirms what I'd kind of puzzled out i.e. the friction pad acts against the V in the pulley.

I could fit one to the clutch arm (there are the holes for this) but I'll probably use the bracket mine was fitted to on the engine plate.

Possibly it was a later mod to the design but certainly factory.

I'll try to remember to get a photo tomorrow.

Andy

[JamesBe1 84]

Interesting. I'd like to see a photo of that. The parts manual doesn't seem to indicate that it is attached to the engine plate. But if it works, it works. Sometimes pragmatism takes precedence over factory.

I didn't get a chance to find the one off of my other D. Do you need the dimensions to fabricate one? Or will that not be relevant if you are going to attach it to the engine plate?

thanks for the picture  !

 

is it an original  of the  D-180 ?

a lot of people need information about that  brake  bracket for that model

would it be possible to remove that bracket and make a blow up  with the dimension and details on this forum ?

so we can reproduce  this part homemade with  accuracy 

it will help  a lot of people and  it will be very appreciated

 

thanks     yves
