Thread: LT 230 PTO speed

FYI, MaxiDrive make one for the LT230

Ron

it is the maxidrive PTO I am probably going to use (I don;t know haven't found any others)
girl on the phone didn't know speeds? hence I'm asking here
I'm adding my own hyd pump and rest of the gear to thier PTO

In answer to your question, you're absolutely correct. The gearbox will decide what speed the pto turns, it is actually driven by the output shaft of the gearbox. 4th gear will be 1:1 with engine rpm. The high/low selection of the transfer case will have no effect on the pto as you rightly supposed.

It dog clutches onto the back of the first transfer box gear, so that is why it needs to be in neutral.
You can, in practice, put her in (transfer) gear and assist your winching by driving at the same time. You would need 1st or 2nd low.
I still don't understand why you want hydraulic tho'-- the PTO winch is fine with shaft drive.

yes you are right unless it is a auto,I have fitted one to my disco am going to see if it is possible to switch on the torque converter lock up clutch I have done this on earth moving trucks when doing tests.

what type of soleniod are you using if you have an ox there soleniod will not handle the flow plus there are other issue's,I've rigged up a switch inside to operate the winch.

Use a seperate hyd tank do not use your power steering resivoir,two main reasons heat build up and leaks,I have to fit a 1 bar check valve
on the breather outlet when i go up steep tracks oil tends to come out and I had mounted the breather outlet behind the tailight.

run our hoses to the winch opposite the turbo I used spiral wrap around the hose's to protect them from rubbing through.

The solenoid valve cost around $300 and mounting block $150 use one that blocks the winch motor and allows oil to flow from pump to tank when in nuetral

Guys

I am not taking the **** but it seems to be alot of work and effort for a winch. I have relied on an electric warn winch for club and comp work and apart from the normal care and maintenance its been ultra reliable.
I would imagine the constant power would be great as long as the engine is running?? Are they that good.

Nothing like a well set up hydraulic winch.
I suggest that you give Maxi-Drive Engineering a call. They can give you an information package on their PTO unit to go on the LT230 transfer case.
I don't know of any other way to direct mount the pump to this transfer case.
They use CROSS gear pumps and recommend the bigger pump - 7.0 GPM @ 1000 RPM
If I read their chart right the cc/Rev=29.5.
The winch should have a spec sheet and a Hydraulic engineer can work out which pump size you will need. Bear in mind that the flange mounts need to fit the PTO unit.
You will need at releif valve set to the winch pressure. The Milemaker from memory is 1,500PSI.
The oil tank needs to be a fair size. The power steering tank is small, bigger to reduce heat.

The winch on my Defender is at pressent worked by the power steering pump which is pathetic. It works very slowly. I will be going to convert the drive to the Maxi-PTO when funds permit.

I've set my pressure relief to 2900 PSI which is less than what the pump is rated at but you do get spikes because there is a slight delay before the pressure relief opens.
yes there is a bit of stuffing around more so fitting one in a disco and you can use the pto to run things ie log splitter hyd jacks or tools.

the power steering pressure is 1450 psi/8.5 litres/min
I have 2900 psi/80 litres/min. I don't know what the line pull is and cannot remember the spec's for the ox winch
