Convert/Redo hydraulic snow pump

[CJONE]

If you look at that chart, the center box is almost exactly the figures I have in post 29. If you only have a 1-1/4 shaft you don't want to play with the figures you are looking at. The hydraulic set up that was laid out will destroy that shaft the first time it is fully loaded at speed with a chunk of ice, dirt ect. Let alone a gearbox only rated for 50hp. CJ

That means I was poking around dead-center :laughing:

I haven't found those 26 & 23 series units you cited, can you give links? I need all the data including weight & maybe approx street price. As for the gearbox I'm aware of its flimsiness (1-1/2" btw, just measured it) and it's coming off except if I continue with a mechanical solution on the existing platform and with a 150hp or so engine (this combo being unlikely but they say never say never).

I'm working on the next edit of my doodle-page but I have just now run into a new issue. In any hydraulic solution except maybe the most powerful one where I might HAVE to use a big gearbox, I intend to use no gearbox but have the motor hold up the fan. This also means a separate motor for the auger and that's the current homework. I think around 100rpm would be OK and anything like 500-2000 ft-lbs. The new toothed augers with teeth are what I need to gouge up any ice and not just broom snow into the fan like some feather duster. Sooo, this will take a low-rpm high torque motor that I can bury into a pipe at the end of the auger axle, or both ends. AND the extra demand has to be covered at the pump level.

Meanwhile the guy I had a deal with on th Duramax looks like he's wavering so that my hearts desire, the 6bt, may be back in the running:cool2:

I am not a computer geek so no links. The simplest way for you would be to go to Metaris usa website and look at the pv and mf series pumps and motors. They are a knockoff company and have import replacements for these units. we rep them and can rebuild replace anything in the Sauer series pumps 20-27. Most of the new stuff is a throwaway unit. That is why I stay away from it. 2000 ft lbs of torque??? Wow I think you need to get a few things worked out before looking for drive components that will deliver numbers like you are asking for. You are getting in the lower range of some of the topdrives and swivels that I build power units to drive, CJ

Search for Sundstrand 26 on Ebay. Yikes, hope you have a fat bank account.

The stuff can be very pricey, I'm going to study the setup and keep different options open for as long as I can. I'll call it probably in late spring or summer. Everything is expensive, as an example the current reduction at the fan involves a gearbox, 2 machinery pulleys, and even the belt cost aroud $500 for a total of around $2300 so that amount really has to offset the price of any hydraulic pump/motor replacing them. If I go for an alternative mechanical transmission like the Allison 6-speed auto and a 3-driveshaft horror under the frame that also adds up to well over a grand used. Finally it costs me $1500/season to farm out the snow removal and that is open to increase (it has doubled in 10 years).

my first response to this just vanushed somewhere, so here goes shorter version #2

About the auger torque: the present setup delivers a maximum of about 370 ft-lbs to the impeller gearbox the sideshaft of which I think is not geared down any further as some others are. On the other hand the chain drive gears it down another 3.5 so we have 1300 ft-lbs. The torque I do have is, like the power all-around, inadequate but I had forgotten that pointed nose-down the auger actually cuts (planes) ice and frozen ground so re-evaluating it I think that even 3000 ft-lbs and more would not be out of place. But I don't know if the skid-steer blowers that use a hydraulic auger motor also use further gearing.

The Char Lynn 10,000 series motors can develop over 2000 lb ft torque. I've seen them go cheap on ebay in the past.

Ya the 57 cuin one will BUT I am really curious to see what the o/p plans on driving with this. Also it would require a double pump system. What we are talking about here is a lot of $$$. There is a reason these units are geared down for the augers and driven off of the main drive. So the torque is developed from gearing and slower speed is needed. I guess I should have asked how much the o/p was planning on spending to start with. That usually tells me how serious they are to start. CJ

Yes, I think hydraulic is too expensive. I think mechanical drive with the Allison transmission is the way to go. There's a utube video of a walk behind blower with a big block chevy for power. The snow really moves.

Agree, but never say never. I've seen that v8 walk-behind, now THAT's starting to get warm except I want it bigger and 30 times the forward speed with a 7 foot mouth. I have 2200' driveway, needs 2-4 passes, not interested in spending half a day on it each time.
