Needing advice

[Bill Frazier 2]

My old d160 auto has taken a bunch of steroids over the winter and put on some serious muscle. She has gained aproximately 1000 pounds in the form of a much heavier 6x4 angle iron frame and a 44 hp 4 cyl diesel engine. How much can the old 1975 hydro unit really take? The old tractor has far exceeded anything I ever thought it could handle but I'm scared of this added weight and the engine just eating the hydro pump for lunch if she ever really gets bogged down. Any suggestions would be greatly appreciated.

Pics to come soon. I'm not very good with compooters and the interweb. I do my best work with a cutting torch, a stick welder, and an 8lb hammer.

Welcome Bill.

 

just one question. what purpose did you have in mind for a garden tractor with 44 diesel HP?

 

my initial advice would be "don't buy Stens wheel bearings for the front wheels"..

Yea, I would do the trailer hub conversion on the front wheels to hold that weight.

 

I doubt it will eat it for lunch any more than the kohler that was in it would. Those hydro pumps have internal relief valves that prevent any more pressure through the system than it was designed for. So you wont get all 44hp to the ground. And i guess if it is in bypass mode all the time from trying to push around the extra 1k lbs then it will overheat and wear out quicker.

 

Just keep her filled up with oil and maybe I would figure out how to plumb in a hydraulic cooler.

 

Then, honestly, when it does blow up just convert the system to full hydraulic. You can get all the parts you need (pump, valves, hub motors, etc) at surplus center. Then you can build a system that will truly take advantage of that extra beef. I want to do that to one of my black hoods but money and time prevent me at this point.

 

And post some pictures darnit, im dying to see that thing!

bmsgaffer that was the info I was looking for. This whole thing started out of my aggrevation at small engines. The twin cylinder kohler bit the dust and so did two more engines not far behind it. Last spring I acquired a multiquip welding machine from work that the generator was shot. I got the machine for free. I mow about six acres every weekend. The extra power and a little bigger deck might speed things up a little bit. The more I think about it the bigger this thing gets. I'm not sure how happy I am with it right now but it is still in a mock up stage trying to get everything right. It doesnt help I keep thinking about articulating and 4 wheel drive. Low and behold my wife says do it after seeing a few of the articulators that have been built by the folks here on the forum.

The Sundstrand pumps will have charge pump and implement overpressure relief. I believe I read in the manual where not all styles of this pump (and there are a few different styles) have the hydrostat overpressure valves. Over pressure in the hydrostatic unit is usually never a problem as component wear introduces great pressure losses. Most older units have issues motoring around 1000 lb + D's never mind those weighing in at 2000 lbs +.

 

Download the Sundstrand service manual from the manuals section and check to see what style pump you have and what can be reasonably expected from that particular style.

Thanks guys for the help in understanding a little more about how the hydro works. I think I'll try the unit just to see how it does if it starts groaning I'll pull it, bag it, and shelf it.

[bmsgaffer 2,043]

Huh! Thanks for the correction SOI, I guess I gave the designers too much credit assuming they would build in a safety of some sort that is standard on most hydro systems.

 

Yep just run it till it toasts then build it bigger and better.

After mowing with all that weight on the steer axle your going to look like Popeye!

Of you want 4 wheel drive talk to mark (meadowfield) http://www.wheelhorseforum.com/user/3321-meadowfield/

I have an Eaton rotary valve and cylinder salvaged from an old forklift. Power Steering! right now I'm stuck with the frame sitting to high, my rear fenders are 8 inches above the rear tires and it doesnt look good at all. Trying to keep it looking stock with nothing more than a stretched front end and oversized tires on the front. The front end is all radiator and motor with the current 23 inch tires it doesnt look to out of kilter but to get the entire frame lower on the rear axle i may have to go with an 18 inch tire in turn the front end looks like its trying to swallow the front tires so im kind of stuck for the moment. Thats why i've been pondering 4 wheel drive and articulating so i can run the same tires front and rear without the steer tires rubbing the frame. I briefly looked at the "bendy" as he calls it and it really looks like a perfect platform for a 4cyl. diesel just maybe scale it up a little bit.
