Anyone ever used one or heard any reviews? The electric is an 8000 lb., but they have a few hydraulic models that run off of a power steering pump. I am really only familiar with warn and ramsey. I am pretty sure that they are used on a lot of military vehicles, so maybe someone has experience with them from that.

I have a 10500lb unit on my trail rig. It works great as long as you have time to spare. I found that it's best not to assist the winch too much as it's not fast enough to reel in the cable. It has never let me down. It's a little lighter weight than the others in the same size class, and it's true that it really can operate under water w/o problems. Very reliable winch. The only two real drawbacks are the slow loaded speed - it doesn't matter how much weight you have on it, it'll always reel in slow and it's somewhat complicated to use. I have mine wired up to an in-cab switch, and with two levers (two speed model) I can't really trust anyone to figure out how to set the speed right...or rather, I'll have it set to low for pulling and they'll f**k it up somehow...

They are a very relaible winch that caqn hold up over time. biggest downfall is the fact your engine must be running, if you stall in the middle of a puddle, your SOL. If you have a very solid powerplant I wouldn't hesitate to go with one. Oh yeah I don't think it would work too well on a factory toyota steering pump. Better when used on a saginaw pump...not sure what you use.

Yeah, I figured that saginaw would pretty much be mandatory if not an AGR. Also wondering about the clearance on the saginaw box, it might be tight.

I have a 12000# on the front of my F-550. But it is run off of a pto driven hydraulic pump. There are two problems with these winches. #1 is running these off of your power steering pump is going to make them VERY slow, as a stock pump puts out about 2 GPM with your engine running @ 2500 RPM. Even an AGR Super P series power steering pump flows 3.4 G.P.M. Not enough IMHO. #2 The supplied solenoid directional control valve has a rated max flow of 3.5 GPM @ 3000 PSI, and has a built in orfice plate to slow down the freespool speed. The orfice will also slow down the winch under load. In my case my pump puts out 16 GPM @ 2000PSI. I bought a new solenoid rated for 20GPM @ 3000PSI as well as a flow control valve. If I open the flow control wide open and have it in high speed it will power in faster than a 8274. If you are doing lots of heavy pulling using your power steering pump, you had better have a good cooler because the fluid is going to get very hot. All in all I have less into this than I would if I had gone with a M12000 so I am happy with it.

Ok, i bring it back, i blow out my sterring pump in a 4.3 Gm, MINE IS 10.500 2 SPEED, i just bouhgt a Gm Super P Series AGR pump, a aluminium radiator for try to go with less º, reading the treadth you say that

THE AGR IS NOT ENOUGH

WHO CAN SAY SOMETHING ELSE
:mad:

jasonmt,

What model pump are you using? How big is it? What size resovouir are you using?

Thanks!

AGR 3.4GPP @1500 psi Gm Super p Series
reservoir the old 4.3 gm
and the radiator is 30x30 cm. off a TH400 auto tranny

Using a Danfoss "YC" Series pump. 1.94 Cu. Inch displacement. 16 GPM @ 2000PSI @ 2000RPM, 3000 RPM max. speed. Reservoir is approx 5 US gallons, with a thermostatic immersion coil to heat it up on cold days.

X-Toys: Willing to bet that your stock pump blew up due to being overheated? The trans cooler is a good start but I would try to find room for a larger reservoir to aid in cooling. After 3.5 GPM you run into flow problems with the stock valves from Milemarker, although I have read that some models are good for up to 6 GPM. Lucky for me one of the guys I went to school with family owns a LARGE hydraulic fabrication service shop and he helped me out with the solenoid valves/flow control valves in return for some INCONEL welding. Have you looked into a hydraboost pump off of a 1 ton truck? Can you put PTO on your transmission?

Keep in mind that the hydraulic motor on a MileMarker winch is 14 Cu. In. for the 9000#, and 18 Cu. In. for the larger models. Increasing your GPM is the only way to speed up these motors. For example on my 18 Cu. In. motor, getting 2 GPM is going to give a speed of 26 RPM, 3.4 GPM is going to give a speed of 44 RPM, and 16 GPM is going to give a speed of 205 RPM (More or Less). Increasing the flow rate without changing the pressure is going to cause a small loss of output torque on the motor due to increased friction. I usuall run mine with the relief valve set at 2000 PSI. vs. MileMarkers Specced 1500 PSI in their performance specs. No problems so far.

This thread has lots of info as well: http://www.pirate4x4.com/forum/showthread.php?s=&threadid=74937

:confused:

I don´t understand pretty well, i´m psicology and do not know too much about technical solutions (and here we speak spanish), i do read the thread and find out that you trying to go faster with the changes off the GPM and the pumps

Correct me if i´m wrong?

My idea is just get the job done, not us quick us an electric, i do wheel hardcore but no comps at all,

Simple question is the AGR the way to pull out my truck up off everything independent of the speed
¿YES or NO?

if not where i can fine a super pump to freight it to Chile,

And (with pics if you can) what are the better changes in the MM step by step?

Tanks a lot

Cristian:
The AGR pump is going to work fine, it will just still be slow. That seems to be everones complaint about the MileMarker winches.
You are going to have to make sure that your fluid is adequately cooled as I suspect that the heat build up is what killed your stock pump and this heat will kill your new AGR pump as well. The transmission cooler is an excellent idea, and I would put a temperature guage on the return as well. I would add a larger reservoir to the system as well to keep heat down. The only modification I would make to a stock winch running off of the power steering pump would be to drill out or remove this orfice plate in the valve body ( Silver )

I've done somethign similar, I've a cross series 40 pump (10 GPM, 3000PSI) running on my PTO. I scrapped all the MM solenoids, and went for a manual lever valve, which has a blow off valve set to 1800PSI.

I like the manual valves as you can feed in the flow quickly or slowly as needed. Also, with this much GPM, it's not good to shock load the thing, and good to start and stop them a little slower.

Anyone manage to find an electric pump that could drive it fast enough?

I thought I read that the cheap($500) 8,000 electric is made in China.....I might be wrong

when i worked at 4WP i sold a lot of both and even have some freind in South Texas with milt humvees with them on there rigs and well the hyd ones are great for work horses even small one with coolers and good running motors they will pull almost all day so if you have a ranch or lots of jobs that will make you use it all day... but as my buddy will tell you if you roll ( the whole reason why i have a winch ) the pto ones are very nice wghts to make your budys electric have to work harder to get you over. so all and all it has more to do with what you plan on doing with your rig, and yes they work better under water that electric ( but elc work under water too) will your motor? snorkle and all i sunk my 4runner in 5ft of water and used the electeric winch to get me out AFTER the motor stalled because of a short... efi and water dont work well. :D anyway thats my 2ct worth working with all of the winches out there i will stay with my brand ( and flame on is just my brand) WARN
