Does anyone have any more recent parts information.
Below is a PM I sent to another member and I believe all the links work-
Wow, that thread is almost a year old. Anyway, glad to help a fellow Kubota owner if I can. First off, the motor is a 1.88 cu. in. Lamina or
Anchor Lamina hydraulic motor I found on ebay. They make a number of different sizes and I had no idea which one did what so I looked for a good price figuring I would deal with whatever I got, but knew almost any motor would work. I found a new A62FM which was foot mounted and I figured the foot mount would help with the installation so I made the guy an offer and he took it. I got lucky. This one has the best speed I think, but I believe the A100 would work well also. See
this PDF for Lamina motor info. If you get a motor that turns too fast you can always put a restrictor in the line. Surplus Center also sells hydraulic motors and
this one is very much like mine with the same SAE 6 ports, 5/8 diameter shaft, and similar torque, speed, and flow characteristics. This motor is usually available on ebay, also. A lot of hydraulic motors have a 1" shaft which would be difficult to work with.
I waited until I received the motor to see what I needed for fittings. These turned out to be SAE 6 for the motor ports so I ordered
2 straight fittings and
2 90 degree fittings from Surplus Center not knowing which one I would use. I ended up using the 90 degree. Note that the fittings are SAE 6 on the motor side and 1/4 NPTF on the hose side. I bought 1/4" hydraulic hoses 4' long but have lost the purchase info on those. They had 1/4 NPT male threads on each end. I also bought a
couple of these or equivalent to make the 90 degree bend at the tractor ports. They connect to the quick disconnect couplers I purchased from MSC
here. I then went about building a platform. I used 1"
square tubing I had left from my rear view mirror project so I used that for the vertical member and I had a piece of 1/4" steel plate laying around for the horizontal member.
I bought two Series L050 coupling halves, a
5/8" bore and a
1/2" bore and
a spider for the middle. Any power transmission or bearing supplier like Kaman or Motion Industries can provide these if you have one nearby. I had a piece of 1/2" shaft stock to connect the coupling half to the blower chute drive.
A couple of notes should you do this project. I highly recommend that you cut extra teeth in the chute flange. If you don't and you overshoot your travel just once, you will be having your worm gear welded up. A few on the forum have found this out the hard way. Attached is a pdf and CAD file of the tooth layout. If you use the pdf file you will need to use a copier to blow it up slightly to get to a 1:1 ratio.
And when you're done you might think that the hydraulic motor will only turn one way. That is because many BX owners don't realize that there is a detent when pushing the joystick right. You need to push beyond that detent for the hydraulic motor to turn the chute clockwise. So you can feather the control when turning the chute counter-clockwise but there is only one speed clockwise. (As a side note, pushing beyond the detent with the bucket on the ground will lift the front wheels off the ground which is handy for getting out of 4-wheel drive.) Anyway, you should also replenish your hydraulic oil.
If you want the pdf or CAD drawing of the tooth layout just shoot me an email address.
