BX2750 snowblower

Now that's what I'm talking about!

So where the heck is Kubota?

I did submit the idea via my dealer to Kubota, no action yet !!!!

Hi Dyer,

Ended up being at princess auto today which is about an hour from me. I picked up the pump and what appears to be the same aluminum bracket you have. I also got the coupling. I just need to make up the bracketo to hold the pump bracket and get the hoses done more locally.
As you said I saw some pumps on ebay but by the time I pay the exchange and the shipping I am not sure how far ahead I would be. I also can take anything back to princess auto - they have a great return policy. Just not sure if I can get it all done before the first real snow- I had to blow 4 inches on Sunday.

Huck,

I thought I should also mention that if you go with the half couplings on the worm gear shaft, you will likely have to grind a 45 degree on the back edge to clear the housing. My picture isn't great for this, but you get the idea. The picture also shows the coupling back on the shaft further than it ended up being, so there is more clearance than what you see. John

John, the parts were delivered last night. I started taking a closer look at the "table" you constructed to attach the motor and mount. I can't tell from the picture but I'm guessing nothing was welded directly to the blower. Rather the angle steel was welded to the top plate and the whole "table" was bolted to the blower through the 3 bolts seen in the photo (2 of which exist in the standard blower. Looks like you drilled the 3rd one.) Yes, no, maybe?

One thing you have to remember on this fairly ingenius mod (kudos to you inventors) is that not every BX owner will have the loader mounts, so Kubota's solution would have to take that into account. They'd have to plan for units with and without the loader mount. That said, I'd agree their current design leaves a lot to be desired.

If it was just hokey (which it is) or ineffective (which it is) then I'd say it leaves a lot to be desired. But the biggest problem I have with Kubota's "standard" setup is that I am confident I will damage the hydraulic control lever and/or valve over time and that the damage will most likely occur after my warranty has expired.

The Kubota approach is not worthy of the word "design." It is almost thoughtless.

Still, I've been having fun looking at better ideas.

I totally agree but people like Kubota only need to look a bit deeper. It may require two different designs to accomodate all applications. The original system that mounted to the control pedestal was a good design. No reason that they could not come up with something to mount on the tractor so the crank could be used properly.

Huck,

I meant to mention that one half coupling was 3/4 in. and the motor half coupling was 1 in. John

John, I just removed the universal joint from the worm gear and tried the coupling. My shaft is a fraction larger than 3/4 inches. 3/4 is 19.05mm. I'm guessing the shaft is 20mm. Did you have to ream that coupling to get it to fit? (called Northern Tool and they don't carry any metric couplings)

It is a lot nicer to deal locally. I also like to avoid the shipping charges when I can and driving an hour is cheaper now than it would have been 6 months ago. Post pictures when you get it rigged. Dyer, retired

Huck,

I am remembering that to be an issue for me too. I did take a sanding drum and work the inside of the shaft to the point (it won't take too much work) where it would go on with some assistance. I ground the 45 degree into the back edge and when I was ready to slide it on for the final fitting, I heated the coupling up with a torch, slid it on to where the allen screw hole lined up with the pre-existing hole on the worm gear shaft and let it cool. The heat will almost do the trick without any reaming, but be ready for it to be pretty solidly fixed when it cools. I sunk the allen screw into the existing hole on the shaft, but I really don't think that coupling will move if you miss the hole and just wrench down on the screw where ever it lands. Sorry, I forgot about that part earlier, but it's really about an hour more worth of work total. Sounds like you're getting close? Dyer, retired

I found a Lovejoy L099-20mm Jaw Coupling at Drillspot.com that looks like it will fit the bill. I may order that one and tell the guy that is putting the whole thing together for me that he has an option. I like the idea of a tight fit but he may not like the extra effort. I don't want to push my luck.
