Happy to help. I'm still working on a multi-part hydraulic series so hopefully you'll stay tuned. I will be covering automotive hydraulic systems as well.
Same general principle. I was ready hoping for a fully functional transmission but I had to make do with this. Hopefully the idea got across and I can make a good one in the future
Thanks for the informative video. I try to take good care of my equipment and wanted to know preventative maintenance. It is a sealed unit, and the best I can go is treat equipment as easy as I can. Again, thanks for the video.
I just bought a Kubota and about to tear into this HST to fix it. It moves, but as soon as the oil gets warm it starts whining its ass off and wont move in high and barely moves in low with a load on it. Just having my mechanical back ground and what I see in this video, I don't see where this whining noise comes from. It appears that the rotary pump is pretty robust. What's a common failure of what I'm assuming is low pressure. Do the rotary pumps fail or do they wear out the housing?
Very cool, like the other guy said it's like some car a.c. compressors, and much like a pressure washer. Do you know WHAT causes these to explode? I just got a used lawn tractor with a working hydrostatic pump and i've always heard people say "they blow up" and as evident by yours that seems to be true.
Contamination pure and simple. Be it excess moisture in the hydraulic system from short tripping the machine, dirt ingestion, or abuse (overheating). Piston pumps are not tolerant to any types of contamination which is why so many small hydrostatic transmissions are sealed units.
