Broken PTO Drive

Anonymous Poster · Apr 14, 2002

Well I really screwed up this time. I just bought my
1510 about a month ago. This Friday I bought a new
36" WAC tiller for it. When I hooked it up I noticed that
the PTO shaft was a little on the long side but I was too
eager to try it out. I made my first pass on the garden and
at the end of the row raised the tiller. What followed was a
series of noises and a tractor that would not move without
stalling out. What I damaged was the PTO drive cluster. The
yoke on the PTO shaft drove it's self into the rear housing and
in turn forced the drive shaft inside. I cut new splines on the
imput shaft inside the gearbox. What I need is a little advise
on finding replacement parts. What I would really like is a
used PTO gear cluster rear housing and all. Does anyone
know where I might find one of these. I'm new to Yanmars
so I don't have the first idea where I can find parts. Are
there other modles that would have the same driveline parts
so I can widen my search? The 1510 has the shuttle shift so
that may change some options. Thanks for any and all help.

Doohhh!!!!!/w3tcompact/icons/sad.gif I'm sure you're not the first or last to do that one. Hopefully some of the dealers in this group can hook you up with some parts.

I would call your tractor dealer first and let them know what happened. They should provide numbers of parts sources, or possibly some parts available. Otherwise call a dealer on this board.

Many of the pto gears for the 1510 are no longer available. We can have the gears machined at a local shop.

Thanks,
Bruce

If you do end up getting the gears machined then make sure they are made out of the right steel and not just what they have at the shop. This will have a big effect on the life of the gear train. Too hard or too soft and parts wear out fast. Even if you cant get the parts you can sometimes still find out the material specifications. Make sure you carefully compare the shape of the teeth and all measurements too. Some of these can be fussy to set up on the gear cutter but its important to do the job right.

How can you tell the PTO shaft was a little on the long side. In a year or so I'm going to be spending (big) bucks on a good finish mower. I want to make sure it fits right and will not damage my tractor. thanks, brettw

Raise & lower it with pto off. It should not bottom out. If it does you need to shorten it.

Brett, PTO shafts are what I call "universal un-fit", - meaning they don't fit anything when you buy them. They are telescoping 2-piece shafts and are always provided for maximum length. After cutting them roughly to length you make a mark on the inner showing where it bottoms out. Then check that the inside shaft is short enough that the telescope can't possibly bottom out when lifting the implement.

Dave, I'm just glad that you didn't get hurt. My own philosophy is that any time you find yourself looking at a handful of twisted metal is a good time to be thnking about just how much force it took to do that.....and congratulating yourself for being one lucky guy.

Well hopefully I can find the used parts I need. Does
anyone know of a source for the gasket that covers the
rear end. I guess I can just seal it up but if I can find
that gasket it would seal much better.

The point about universal un-fit is absolutly right. I'm new
to tractors and do plead a little ignorance. Is there any
problem with just hacksawing off the required amount off of
both ends of the PTO shaft?

Thanks
Dave

I have not tried this, but someone on a previous post said to raise the implement to the highest point with the pto shaft unhooked from the implement, then make sure the shaft will just hook up with no binds. Makes sense to me.

Ernie,

Do you have any front wheel drive components on the tractor or is it only 2wd?

Don't feel bad, I had the same experience with my 1510. I was bushhogging when the rear wheel fell into a big hole. in the process of trying to get out of the hole, I jammed the PTO shaft into the PTO housing. I had the same results as you. I found a used gear cluster from an importer in Georga. I can't remembre there name, but I can look it up tonight. E-mail me if you would like there name. The cluster came off a junk tractor. It only cost $175 Shipping included. Best of all, It was on my door step in 2 days. As for resealing the tranny case, Go to your Local autoparts store and ask for Blue RTV. It works great.

normde2001 · Apr 15, 2002

Yanman, did this happen because the shaft was too long and bottomed out when you lifted it or did it come apart when when the cutter fell in the hole, (too short)?

Soundguy · Apr 15, 2002

Ouch.. sorry to hear about both of your bad pto experience.

I just bought a 3pt spreader, and of the two options the store had, I opted to buy the one with the flexible pto shaft, just so i didn't have to hassle with it..

Yanman,
I would like that contact information from the guy in Georga.
I'm going to try to get one from Ernie but it never hurts to
have a backup plan.

Thanks
Dave

AlfaRs,
I will get that info for you tonight and post it in the morning.
As for the question about the PTO shaft length, it is too long. I havent taken the time to correct the shaft length yet, but hopefully in the next few weeks I'll be able to get to it.

yanman · Apr 15, 2002

AlfaRs,
Now that I think about it, Tha yanmar importer that I got the PTO gaer cluster from is Fredrick's Equipment in Alabama. Their number is 256-773-9951

Yes, you can cut the shaft to fit. I used a sawsall and it worked just fine. Cut equal amounts off each end. Just make sure you don't cut it too short. You can only imagine what would happen if the shaft came apart spinning at 540 rpm.
