(Master control valve is why the master control SPRING is located just under the seat at the rear of the lift cover. That puts the master control valve (operates draft control system) in tension, resulting in the draft arms not wanting to lift. Using the draft control curcuit, even with position control in constant pumping, will not respond well to attempts to lift HEAVY loads. Partially lowered, it won't supply enough flow/pressure to allow the draft control curcuit to operate the lift. With the position control lever lowered to any point beyond fully raised, the pump only operates enough to maintain the position of the lift. That's locked in when using a remote hydraulic auxilary valve OR a loader plumbed into the internal hydraulic system. The position control/constant pumping lever has a detent all the way at the top. (operating ground engaging implements) When using either one, the other should always be in the UP position. It's used to operate the 3-point hitch when plowing, subsoiling, ect. The other lever (one with round knob) is the DRAFT CONTROL lever. It's what would normally be used to operate the 3-point hitch.
That "constant pumping" lever is the POSITION CONTROL lever. Every one I've been around, the pump rattles with the position control lever in the fully reaised position. I've had my hands on maybe 45 or 50 in the last 30+ years. I buy, recondition and then resell 135's 150's and 165's for extra income. It's rattled when in CONSTANT PUMPING for near 35 years of that time. I've owned the 150 pictured in my avatar since new, 37 years ago. It's a combination of a little slack in the mounting dowels that hold the pump in place and the relief valve cycling.
Massey ferguson draft control adjustment series#
(sounds sorta like a rod knocking in an engine?) That's normal on most all 100 and 200 series Massey's. At best, it will only raise with ZERO load on the draft arms.įirst, those "not so nice noises" are normal. That will cause the lift to work very erratic if at all. I'm getting the impression that "constant pumping" lever isn't all the way in the raised position and you're trying to use the OTHER lever as the only control on the 3-point hitch. Some times you can rebuild the pumps, but I have found that always not to be the most cost efficent.Ĭlick to expand.I MAY be all wrong, but. If the Pump is bad, you must split the tractpr between the diff and transmission.Īs for price, The pumps will range from $900.00 to 1500.00 depending on the correct pump. The price will vary because of the different models. If the Pump is bad, and lets make sure before you spend the money, There are Aftermarket pumps.
Massey ferguson draft control adjustment manual#
It would be best to get a Repair Manual before going any farther. Still low pressure?ĭoes the pump seem to be making any noise? Will the PTO shaft turn? ( the same shaft that turns the pump turns the PTO) If the PTO shaft turns, then the next thing to check is the adjustment of the pump stroke lever. If the oring or backup are damaged, replace them, slide the tube back in, remove the dowel, replace the cover, and recheck pressure. The tube should have 1 oring and 1 backup ring on each end. This will allow you to slide the tube back in place latter. then get a wooden dowel that will fit inside the tube (16" long), Then pull the tube out over the dowel. Trytp leave the tube in place and only remove the cover. Take out the 3 allen head bolts, there is a tube going from the cover to the pump output. If you have some pressure there is something else to check. The start the tractor and go to "constant pumping". Try to put a pressure gauge (5000 psi) in where the pipe plug is. If you are sitting in the seat, just under your right knee, there should be a small cover plate. Since you are not saying you have remotes I am guessing the Ferguson only. If there is no line the you just have the Ferguson pump.
The ferguson pump runs the 3 point and the Aux reuns the remotes. If there is a line you have a Furgeson (3 point) punp AND an aux pump. First you need to know if there is a hydraulic line coming out of the round plate on the left side of the diff housing, where the PTO lever is.
