For design specs of 30 fpm line speed and 10,000 lbs line pull full drum: 516 rpm at motor 247 ft-lb at input shaft (motor output) 24 Gpm 2011 psi (used a 2000 psi relief cartridge in valve) This considering a motor (Parker 113A-106-AS-0) with 10.6 cu in/rev displacement fed by pump (Muncie...

you can also consider flipping the bumper extensions over and mount the winch on the bottom of the frame - this get the hyd motor well away from the radiator and should also put it below the engine mount cross member. you should still be able to orient the winch upright, however, you'd need to...

you can do it without solenoids - you could use a hydraulic selector valve; primary A and B ports in, two different A and B ports selected manually. i had considered this route as a potential upgrade. I could put this selector valve after the spool valve and use it to select which winch (F or...

Let's try the video. It's short, I didn't video all of the testing. It's weak (literally), I didn't video the 4 wheel drag for the sake of the yard. Rather, all I wanted to demonstrate was the process and control over the winch. Enjoy.

Soooooooo...... Imagine that... it works!!! :shock: I still never got my last fitting that I ordered (it should be here Tuesday :rolleyes:). I got tired of waiting and went over to Cline's and pieced together an obnoxiously intricate arrangement of steel fittings to get to the suction hose...

Well, yes I do have a list of all the fittings that I used. However, that may not be a perfect recipe if different components, locations, and hose runs are used. All fittings and hose was purchased from Discount Hydraulic Hose; the pricing is good, however, most fittings are Chinese-sourced...

The attached spreadsheet was developed by a friend. The blue fields are required user data and the red is calculated data. Let me know if you have questions, but it's pretty straight forward. Edit: nevermind - looks like you're not allowed to attach xls. I'm sure there's a good reason...

For sure!!! The answers should be Yes, The same, and Yes. Mainly, I'm after the 'safer' part; the hydraulic winch cannot be left in either Pay In or Out by error or default. Therefore, the hydraulic conversion is more condusive to safe winch operation by a solo operator. Not really. You...

I'm thinking you're correct. Motor diameter is ~4.5"; it is located approximately 7" in from the inside of the frame vertical web with a total width of about 9.25" from the same location. It's hard to figure the top since the OE radiator is no longer there, but there needs to be about 5.25"...

I honestly think that you're going to be hard pressed to readily find a 20k lb hydraulic winch in the 'affordable' neighborhood. I've got about $1600 in this conversion: PTO adapter PTO Pump A3 Motor, stand, coupler, tank, filter Valve Hose & fittings You can sell the winch PTO parts to...

To maintain 25 fpm line speed on bare drum (which may not be necessary) the motor will need 20 gpm.

no - it's from the repower and is completely above the frame rails and not between. however, the motor does [obviously] occupy the space that the OE drive shaft does, and therefore the area in the radiator that has been clearanced to accomodate this. What I can do is measure the motor...

ah, I understand what you're saying. For curiosity sake I'd like to now pull up the winch parts drawings to see what style bearings used to control axial thrust. I'll have to get back to you on that. you think the -34 will give shaft runout...?

G' - do you have a PN or specs on that spool valve? I do like it's size, but have a concern that it may be quite restrictive on the flow side. Interested, though...

Yes, the winch mounting is all OE - all originally installed on the truck. No modifications were done to the winch whatsoever. It's been there the whole time. The mount and motor fit nice and snug above the front crossmember - it was made to go there.... literally.

Yeah, the tank is going in the bed. Since I don't have the suction fitting, I cannot complete the circuit. I didn't want the tank sitting in the bed open outside, so it is still in the garage avoiding accumulation of condensation. Good eye - no tank means that the return line from the valve is...

G', that's actually exactly where I wanted to put it!!! However, I plan on adding a rear-mounted winch in the future. A dual-spool valve flat won't fit. The single spool valve won't fit w/ JIC fittings on the In/Out ports; however, I think it may fit if i use NPT fittings... maybe. I weighed...

yep, sure could have. except I didn't want the winch to be 30% of line speed, <70% of the line pull, and neuter the power steering while in use.

So that's where I'm at until that silly fitting shows up. Soon as it does, I should be able to throw on the suction / return lines, fill 'er up, and test 'er out. That is, as long as I got the In / Out on the pump correct... Stay tuned.
