Lost drive shaft pin
 

Hey guys.

I was mowing with the 147 today and I heard a TINK, then she slowed down (forward progress) then movement from the hydro lever didn't do anything. I knew immediately it could be two things- the front dowel pin on the drive shaft or the rear. Naturally it broke down in the corner of my lot as far away from the garage/tools as possible, right where I figured it would when it finally would stop moving on its own.

Thankfully it was the front drive shaft pin, and when I did my rear end overhaul a few months ago I had bought more than one in case this happened. The pin (that was gone) was new, and was the correct one via parts look up. Even more thankfully it was still within the space between the frame as I have the bottom and rear tin plates installed, so all I had to do was re install the old one. Viola! That was the culprit.

Here's where my question lies. To keep it from working its way out again, what should I do? Loc tite it in? I've seen the hose clamp repair, but I'm looking for something a little less ghetto.

Thanks!

I had the same thing happen on my 123 several years ago. It was colder than "heck" and I was plowing snow at Moms house (far enough away that I had trailered the tractor there).

Ultimately, I laid the shaft across the jaws of the vice and hammered on the hole on one side, then drove a new pin in from the other side.

Right wrong or otherwise the pin is still in there. I used it for moving snow several years after that, but now it only sees a little dirt work in the warm weather when there are no blades on any of the other tractors.

Drill and tap a 10-32 hole perpendicular to the pin. Grind a flat on the pin for the set screw to sit on. Now take your hub off and drill a 1/4 hole that lines up with that set screw so you can install it after you put the hub back on and install the driveshaft and pin. Better drill that 1/4 hole all the way thru that hub so it stays balanced.
That's all I can come up with if you never want your pin to fall out without using loctite.

Paint the hose clamp YELLER than it ain't RED neck. :biggrin2:

One of the rear pins in my 102s drive shaft kept coming out. At the time I could not find a new connecter so I hose clamped it. Was in there for years till I came across a new connecter. Yes my neck is a little red but it worked well.

This was my cure for a worn out coupling on my 149. Part of a 2000 series shaft. It bolts to the engine so it makes servicing the drive shaft a breeze. The 2000 shaft has a 5/8" ID so all you need to do is to cut a couple inches off the engine end of your shaft then slip the 2000 part over it, mark it where you want it then drill it and put a spirol pin it and your done. :beerchug:

They do make oversized dowel pins.
0.001 over is a common one if you can find one versus buying 25 at McCarr, etc.

But if you throwing pins, the shaft hole is getting worn.

You could also drill and tap the very end of the shaft right at center and install a 1/8"dia. cup point setscrew.

I can made a knurled pin to replace the smooth pin. I can make it up to .003 to .004 oversize

You should be able to sell a bunch of those. Way easier than what I did
