B2782B Front Snowblower Mounting Problem

[mikehengton215]

It sounds like the rust and tight fit may be causing the issue with the drive shaft connection. I recommend applying a penetrating oil to both parts and letting it sit for a while to loosen any services corrosion. If the parts still won’t separate, consider using a puller tool or reaching out to a dealer for professional help, especially if the shaft is stuck.

So the blower and front two pto peices are not mounted to the tractor and subframe? Do you have a jackall? Try and lash one end of the pto to the jack the other end against the blower and then use to separate them?
Initially I was thinking everything was attached to your tractor and subframe but the photos show otherwise.

The two PTO shafts are connected to each other (jammed) and attached to the snowblower, but not to the subframe.

I tried pulling them apart, tapping them apart, and spraying them with a penetrating oil.

Nothing seems to be able to get them apart.

I still need to see how to remove the PTO shaft from the Snowblower so I can just take the two stuck pieces to the dealer.

I gave them a good dose of spray but couldn't get the spray into them since they are stuck together.

I did spray coat them with some grease prior to putting them together. I did try tapping them together at first and was able to pull them apart.

That's when I gave them a good dose of spray before I put them back together and tapped them pretty hard in hopes of breaking loose whatever grit/dirt may have been inside the fittings.

I guess banging them together was my fatal mistake.

I did see that the grease Zerk was damaged and came out during the attempts to tap them apart.

I hope a new grease Zerk will just screw back into the hole.

Can you roll the snowblower over far enough to see the bottom side of it? That way, you or someone here, could probably figure out how the pto shaft is secured to the snowblower

Here is the manual for your snow blower.

Page 30 shows items 18 and 19 which are the long bolt and nut that hold that half of the shaft.

I am glad I did not buy kubota with a front mount snow blower.

A slide hammer and some binder wire would have those shafts apart in less than 1/2 hour!

I've used my vehicle hoist to slowly pull those shafts apart. I didn't want to yank them and possible bend them. When they do come apart, paint the male end and shove it in until they bind a little. Then pull it out and look to see where the paint has be scratched off. This may tell you that a surface grinder is all that's needed to round out a corner or 2. Yes I know the shaft ends are supposedly keyed, but check to see that the inner yokes of the U-joints at each end are exactly in phase (they look to be the same from both ends. If the shaft keying pin is removable, grind it off and insert the male 180 degrees from where it was. Perhaps the pin was installed incorrectly. If so, you would also have to change one end of the driveshaft yoke to preserve its phasing

It's 400 Lbs so not easy to flip it. I will have to wait for some help.

In the meantime, someone told me that there is a bolt that secures the shaft using a compression collar and a keyway pin held in place with an allen screw.

If I can figure out how to remove that metal shaft guard, it would be a lot easier. From the parts diagram, it looks like just some nuts/washers hold it in place.

Hi All. Once again, THANK YOU ALL for the help, support & Guidance in my quest to separate the two PT shafts.

It's been cold and rainy here the last week, so I didn't really have a chance to work on this problem. I did move the snow blower to a different loaction, then dismounted the "Sled" from the tractpr so I could mount my FEL as I would need it to load the blower on a trailer (if I had one) to take it to the shop.

After I moved the blower to a slightly better location to work on it, the first thing I did was try to release the Shaft Guard(s).

NOPE! feel like a complete idiot, but I could NOT see how to release the shaft guard. If I could to that, I could not move it over the universal joint, but it would allow e to better squirt my liquid wrench into the stuck parts.

SO I just blindly squirted the parts with a healthy amount of Liquid Wrench.

Next, I thought I would release/detach the female PTO portion from snow blower. How hard could that be?

It's a tight area, but I did manage to get the thru bolt and nylon nut removed. OK... I figured the rest would be easy. NOPE !!!

I was unable to remove (or even loosen) the set screw. I sprayed it liberally with Liquid Wrench too, but to no avail.

I actually bent my allen wrench trying to loosen it. I gave up any further attempts in fear I would strip the set screw.

What now??? I came up with the bright idea to hang the blower up in the air (just a few inches) by securing a chain thru the Universal joint to the male end.

Then hung it in the air using my FEL overnight. (Of curse I gave it a few more liberal sprays of Liquid wrench.)

While it was hanging, I tried whacking the shafts with a board in hopes the vibration would help the Liquid Wrench soak in, and maybe even cause the parts to separate. No luck.

The next day (Today), I sprayed the parts again as best I could, and whacked them some more.

As a last resort, I tried using my FEL to raise and lower the blower , rather forcefully (read "jerking action"), and prayed they would come apart.

SUCCESS !!!! They separated.... YIPEE !

Now I have to remember to go back and tighten the Bolt & Nut back up and see if the Set screw has loosened up at all.

I will see if I can purchase a wire brush on a long shaft to run into the female part of the shaft and hopefully clean it out some.

The male part of the shaft, I will go hard at it with a wire brush on a drill in hope I can clean it up as well.

Of course, I still have to figure out how to release the safety shield on the shafts.

I'll keep you all posted.

leonz, Thanks a bunch for the Owners/parts manual.

It helps a lot.
