What about a small hydraulic motor, mount an extra spool valve on the fender...could even do two spool and have chute angle with a small cylinder too.

Can anyone guess what this motor might be destined to be used for on my 444? Heck, can anyone guess what this motor came off of? It was a new one to me that's for sure.





It's just in the early design stages so I may go with another motor but this is the front runner at this time.


So I heard back from the seller of the first motor I posted about and here's what he had to say:

"the motor rotates at about 45rpm. Today, I did some calculations to see if this might work for you. Here's what I found:

I figured by the time you put a pulley or sprocket on the output shaft of the motor, you'll have a diameter of 2" minimum. This gives you 6.28 inches of circumference. At 45rpm, that's 282.6 inches per minute or 4.71 inches per second. For the tractor chute I guessed at about 12-inch diameter & added an inch for a gear segment or pulley which ends up at 13 inches. This is 40.82 inches in diameter. Since you only need to rotate the chute 180 degrees, we only have to work with half of that, or 20.41 inches. Since the pulley/sprocket surface speed on the motor is 4.71 inches per second & we're trying to move 20.41 inches, we can conclude it will take about 4.3 seconds to get this done, which is within your range.
"

Any math geniuses out there that can tell me if the above math checks out or not?

My original design with this motor was to cut the coil off the rod that turns the chute and spot weld it back on the shaft of this motor. Then mount this motor directly to the mounts of the blower housing. Isn't this FUN?

2:54 a.m. and my marathon night is over. I was able to wire up the back up light, install the chain and get the hood prepped for the lights to be installed. A new lens is coming Monday courtesy of Casey, a generous member from this forum. I learned a thing or two about the usefulness of half links tonight. The auger is a bit further from the inside of the housing (1/4") than I would have liked but it was the only way I could make it work; I couldn't shorten the chain any further so I will have to see how she runs and take it from there.

I think I may have solved my chute turn rod situation but I won't know till tomorrow; I need to bend the bracket that holds the rod forward so the rod will clear the muffler. I'm still moving forward with the motorized chute rotator but I need to be able to turn the chute should we get snow before the motor arrives and I am able to get it installed.

Tomorrow I hope to get the strobe light hooked up and ready to go. Enough for tonight (this morning) my alarm will be waking me very soon.

Cool. I think the hand crank is fine for turning the chute anyway. I was thinking of changing the chute on mind, I wondered if a longer, narrower chute would thow the snow further.

I am in the process now of swapping my front wheels to 4 bolt wheels w/ hubs and roller bearings. I'm sticking with the 3/4" spindles. Waiting on my 18x8.5x8 V61's now. I'll post a thread with some pics once I finish it up. No modifications neseccary. Bolt on and go.

Also thinking about doing the poor mans power steering mod. You should look into that. The blower makes it hard to turn the wheels, and even when you do it doesn't go anywhere but straight with the stock tires.

Hey, you mentioned you were looking at going the hydraulic route for a chute turner? Take a look at this thread:


http://www.tractorby...te-rotator.html

I've heard that a longer chute will throw the snow farther. I've not seen a snowcaster with a longer chute. Did they come with one?

I'm with you on the difficult turns with the blower on. I'm in the market for front chains due to the front slicks.

I'm interested in the mechanics of the "power steering". I'm visual and can't picture it....that's code for.....help I have no clue where to start even thinking about the concept.....HA!

Why change your wheels?

Here's a sneak peak at the recent modifications and refurb of the Snowcaster. My daughter is cold and definitely not and excited as I am but she was a trooper; BTW, she's the one who did the clay animation video.

Here's another real neat example of a very clean cut modification of a chute turner:

I really like the way he slowed his motor down by way of using the sprockets. I also like the way he made the modification look pretty darn close to what might have been stock.

The hydraulic chute rotation was just a suggestion for you, I wouldn't do it on my own blower, its just a little too much. I have a couple large Normand blowers (about 8ft? wide) with hydraulic chute rotation on them. Pretty handly setup, but just too much for this application.
I have also thought about using a cheap winch, I see them on sale for $30-50. This would also work fine for turning the chute.

OR you could cut the end of the hand crank off, and put the rod into the chuck of a cordless drill? Just an idea...lol

The Case blowers never came with any other chutes, to my knowledge, but I can't see making another fit being much of a hassle. I seem to remember someone, somewhere switched a chute out, but I can't remember if it was a Case blower or a single stage Massey blower.

As for the "Power Steering" check out this ebay ad. You can get the parts needed minus the "protective cups" for about $10 from "Motion Industries" I think it is. I need to look up the P/N's though. http://www.ebay.com/...=item3375e0f00b

Why change the wheels? Why not? Seriously though. I'm going with 18x8.50x8" tires to replace my 16x6.50x8 tires, so I wanted a little wider rim, not that I needed it. But also, by upgrading to 4 bolt hubs, I can run tapered roller bearings in place of the stock ball bearings. These will last MUCH longer than stock and carry more weight.
The reason I'm switching from 16" front tires to 18" front tires, is because I run 9.5-16 rear tires verus the stock 8-16 rear tires, they are considerably larger, so my tracor has a bit of a rake forward.

Yes, my 444 Demo.

McMaster Carr would work for you southern guys, no shipping to Canada last time I checked. Those exact parts wouldn't work though. the 400 series have 1" spindles where they mount to the axle, not 3/4".

The Motion P/N's are:

B32312 for the washers, 4 needed. $0.95 each
B32196 for the needle bearings, 2 needed. $2.73 each

Total = $9.26 prior to shipping.

Well I'm the proud owner of a Cessna flap motor. Now to see if I just bought a paper weight or if it will truly do the job. I'm sure Vegas would be able to give you odds for the purpose of betting if you wish to bet on my success.

I think I will try to use sprockets and chain maybe to turn the chute. Isn't trial and error fun?

Mac & marlboro, I'm sold. That's a pretty cool idea. Have either of you ever tried it and if so might you have a pic or two? Thanks for the sources and part numbers.
