OK, simple fix for the continuous pump running. The microswitch on the end of the PTO lever was knackered. ROTEC suggested that and sold me a lucas switch. That job done. The noisy pump was an oil cooler (low pressure) circulation pump. That needed changed too. Thanks for all the input.

Rotec got back to me with the engineering drawings for the units on the land-rover, I have not had time to read them yet, but they say the pump is a cooling pump and that the switch is available from them. I have tried to upload the copyright notice ! and the details of the sales guy who sent me the stuff. but I keep getting upload failed. Worked a bit. I was speaking to Ian Ford art rotec

OK, I am not ignoring you but the heat is playing havoc with some of our systems! Once the world cools down a bit I will take the time to go trace everything and get a plumbing diagram and photos as good as I can make em. Thanks

I guess I am trying to locate somebody who has seen one of these units and can say what the components are. The process of buying a pump and filter etc is easy, but if it fixes nothing - because I have a blockage elsewhere or such-like - is what I am trying to avoid. Below is the diagram from a superwinch install manual. It is very like mine. But as professor once taught me nearly means not. Their diagram and my LR are similar - a pump on the PTO taking the hydraulic to a motor on the chassis near the winch. A pto shaft doing the rest of it. I have checked the oil levels and it is "between the lines". It also looks clean and without grit/metal etc. The noise from the pump only started the minute I put the PTO on. And then did not stop when I took the drive off! The 12v pump was running all the time the ignition was on. It is a low-pressure pump (compared to the mechanical pump). So I assumed it was a oil cooler circulator. But when I found this diagram I withdraw that thought! I need to go get the real manual and/or go trace all the plumbing. I think that electronics are involved somewhere - with the throttle control and emergency stop all wired into a control box. I have been emailling Ian Ford at rotec - but I am away from home for days at a time, so my email responses to them are a bit sluggish- they might think I dont care!

David: Agreed about cleaning. I am off to London for a few days on work tomorrow early. I will see if I can clean up the beast when I get back. It was Western Power Distribution as the owners. There is no livery on the beast and the MOT does not show much - except each MOT was OK. WG09LFR is the reg, the battery was knackered when I got the beast, so I suspect it had been sitting for a while. Why does it whine - perhaps pump knackered, or perhaps dry?? - maybe blockage in the pipes?? More importantly why does it not stop when the PTO goes to disengage (and the PTO shaft to the winch stops turning?) I really need a circuit diagram or somebody who has been here before. Somebody might tell me "Yes, they whine like that all the time they are running" I have no idea what is normal. I normally use my old fergie and a rope when winching, so an LR power winch is new to me.

The PTO stops turning (at the bumper) when the PTO lever is pushed back. Also when the clutch is dipped. Like you I fear something in the electrics are not happy. I cant find a make/model or circuit diagram of the electrics NOR of the H14W. The pdf in this thread is 'almost' perfect, but seems to lack my electric pump and filter. Is this operator error. Not enough oil somewhere or tap the 12volt pump with a wooden hammer shaft?

Pictures are just up. I have done nothing yet except look and wonder, I am trying to identify what I have before dismembering the beast. I could survive the whine if it stopped when then PTO was disengaged. BUT while I think I can perhaps hear the gentle click of a microswitch when the PTO is operated (engine off) I cant find wires nor the switch anywhere near the pto! Incompetent or what? Under both seats is a right mess of control boxes and wiring. The LR had radio, external lights, hazzard lights everywhere and also has some form of auto revolution/auto load controller that takes control of the engine revs when it is switched on. It also has an engine cutout on the bonnet - beside the external winch controls. I am not afraid of electrics but a circuit diagram would stop me spending days in the wrong fuse box. Oh wait I have done that already ;-) The only way to stop the whine - was to switch off the engine.

FridgeFreezer, let me tell you a wee story first.... I am a target shooter. I broke a wee bit off the butthook on 1 of my rifles. I tried to explain where it was (to the German manufacturers) in words. Back came the message. "Please send a photo". So I did. Back came the message (from the humourless Germans?) "We hope you are a better shooter than a cameraman, but we see what is broken". On that story, view on. The exhaust box and the subframe and the prop shaft all conspire against me, I cant get the pump and the orange thing into frame at the one time. There are two things "in line" a 12volt pump (white/ blue in photos) and a similary sized orange ?filter? behind the pump. The pump is about the depth of the chassis.... I can try for ore photos, but trying both my phone and my "decent" camera I got no where. I do have oil in the hydraulic tank, the winch did winch forward and back, The whine that would not shut off is the issue. When engaged the pto into the winch would run, when disengaged it stopped running. All help appreciated.

Wilco. BUT just in tonight, so a bit late to crawl underneath, I will get the camera out tomorrow morning.

Looking for help with an LR with a PTO superwinch. Ex utility company. I engaged the winch - works fine. BUT had a help of a whine from a ?pump? behind the drivers seat bolted to the chassis. disengaged the PTO, and the whine continued. I cant find a manual that help me figure out what the 'thing' whining is - it is electric, The manual above is oh so close, but does not have the "thing" that I have on the schematic. It looks a bit like the fuel pump/filter on an old LR disco - pipes in and out, power and about the same size with what looks like a filter screwed on. I took it to my local friendly MOT shop and asked them to disconnect the electrics to the 'pump' if they could not find out what was wrong. Unfortunately the stripped out a lot of bits. Stops the whine, but stops the winch! Can anybody tell me what the unit I have is? If things help I had (now stripped out) a warning light that came on when the PTO was engaged - DONT ENGAGE REVERSE.
