[QUOTE="wateka, post: 131061, member: 21519"] In trying to bird-dog my charge pump with zero pressure issue after my rebuild, I found the OEM manuals for the Series 40 M46 Tandem Pump. These are used in multiple models (mine is an 853) and the data plate (on mine, at least) shows M91-xxxxx. The graphics and detail in these, relative to the Bobcat Service Manual, is stunning, but having the Bobcat manual(s) is just as important. In searching the forum archives relative to my charge pump issues, I found comments such as “Throw some [pressure] gauges on there.” No doubt that will be helpful for diagnosis, but what gauges do I need, where in the heck do I attach those gauges, and what reading(s) should I be seeing? Those types of answers, including the list below, are in these manuals. Pressure measurements [LIST] [*]Required tools [*]Port locations and gauge installation [/LIST] Troubleshooting Overview [LIST] [*]Safety precautions [*]System noise or vibration [*]System operating hot [*]System will not operate in one direction [*]System will not operate in either direction [*]Neutral difficult or impossible to find [*]System response is sluggish [*]Electrical troubleshooting [/LIST] Attached are: Parts manual Service manual Technical information Overhaul gasket/seal kit description The original manufacturer of my pump in 1993 was Sauer Sundstrand (often misspelled Sunstrand) who later became part of Danfoss and now there's a JV with Daikin. I mention all this because there may be updated versions of these documents in the future on different company websites such as danfoss.com, daikin-sauer-danfoss.com [ATTACH type="full"]5115[/ATTACH] [/QUOTE]
