richp Posted February 6, 2005 Posted February 6, 2005 Can someone give me the specs for the hydraulic cylinder used on the old powerlifts. I need stroke, collapsed length, bore and anything else. I to find a source for these. I looked in Grainger and Northern hydraulics, but they seem too large. Can you get them from Simp. Thanks.
richp Posted February 7, 2005 Author Posted February 7, 2005 Thanks, that is what I need. I had a hydro lift on a 3112h and want to fit one on 2 7000 series tractors.

Tom45 Posted February 7, 2005 Posted February 7, 2005 I am not sure about the 7000 series, but the cylinder on the 7100 series that fits underneath the tractor is somewhat different from this. If it has a Sundstrand hydrostatic drive, changing the relief valves can allow the charge pump to operate the cylinder, as discussed in some previous posts.
HubbardRA Posted February 8, 2005 Posted February 8, 2005 Rich, I am currently installing a hydrolift on an AC716H. The cylinder is different from the one John shows in the picture. I bought one from a Sunstar on ebay. It is the same as used on the 7100 series Simps. In fact all of the 7100 parts can be bolted to the 7000 series if you drill a few holes in the frame. I am making my lever from a shuttle lever from a 410, since the whole pivot assembly bolts onto the 410 instead of being welded on. If you use the shorter cylinder from a 7100, you will need a 7100 rear cylinder mount. It bolts directly to the 7000 frame. If you go to the Simplicity manual site and enter 400 as told in Maynard's sticky, then search for 7116H, then go to the second document found, this one will have a breakdown for both a manual lift and a hydrolift. It will show you the whole setup for the 7116H and this will also work on a 7000 with Sunstrand hydro. That is what I did. You can also use or make a BGB mount like the older tractors used and then use a longer cylinder. If you get under the tractor and measure from the cylinder mount on the rockshaft to the front of the BGB, you can determine the collapsed length for the longer cylinder.
