FrankinWNY 12 #1 Posted July 3, 2021 Who rebuilds Eaton 7 pumps? I have two that are weak, oil looks OK. How much? Share this post Link to post Share on other sites
Handy Don 12,457 #2 Posted July 3, 2021 Good questions. Following. I have one that seemed strong when I used it but that 518-H donated its engine and topsides to a project built on an 520 chassis with an 1100. Share this post Link to post Share on other sites

Tuneup 1,433 #4 Posted July 5, 2021 It would be great to read a thread on the reasons why these weaken. Plenty of info on talented gents teaching how to refresh a Sunstrand. I'd love to see the same on the Eatons. Share this post Link to post Share on other sites

There is a thread somewhere here on Eaton 1100s.. Thing is Eaton 1100 series are newer and very reliable. Eaton 700 probably not worth the effort... 1 Share this post Link to post Share on other sites
Handy Don 12,457 #6 Posted July 5, 2021 (edited) After doing some specific research into these hydros, I abandoned a 700 mainly because I wanted hydro lift capability and I expected to do some heavier pushing/pulling. From the Eaton specs, I concluded that the 700 was a solid pump/motor but not intended for intense use. IMHO, the 700 will give good service for mowing and blowing, i.e. where the hydro's job is mainly moving the tractor and rider around. Asking it to also push a plow or blade or pull a heavy trailer, where you want the hydro to move the tractor, the rider, and something else, is unfair. It simply exceeds its designed capability. Once can be lulled by a 518-H's horsepower and size and ignore WH's recommendation that this unit was not ideal for the pushing/pulling uses. The torque ratings tell the tale. Eaton 700 -- Continuous: 150 in. lbs., Intermittent: 228 in. lbs. (at 3,000 RPM, can continuously deliver about 7.5 hp to the transaxle/wheels, intermittently up to 11 hp) Eaton 1100 -- Continuous: 360 in. lbs., Intermittent: 540 in. lbs. (at 3,000 RPM, can continuously deliver about 17 hp to the transaxle/wheels, intermittently up to 26 hp) Note that the above excludes the power demand to spin the mower or the blower because they are direct off the engine PTO Edited July 5, 2021 by Handy Don Share this post Link to post Share on other sites
