Hi all.

So I've ended up with some PTO winches. I have one here and its from an MQ? safari (as pictured in the for sale thread).

I'm wondering what the main differences are between this earlier PTO winch and the later model GQ winches. Is it still a good winch, is it as strong, will it fit a GQ, what parts are compatable (gearbox extension, shafts, engagement lever etc)

Also- has anyone ever seen one hydraulically driven (a pto driven by a hydraulic motor)? Just curious

hydraulic all the way

2 mins on google came up with:

MQ ones have only 4 bolt holes

Keep in mind another way to set up a PTO is to just use the box. The box then drives a PTO hydraulic pump. You can then run hydraulic winch both front and rear off the same PTO box and pump

Cheers Daniel

Thanks lynx.

I have an auto so actually have no way of outputting any kinda PTO drive (that i know of).

Would have to be belt driven hydro pump.

Where to people source their pumps from? Power steering pumps are commonly used but do not flow anywhere near enough.,

Looks like the same number of mounting holes to me?

MQ:



GQ:


obviously the gq and mq units have slightly different case at drum/box

lol.........one of those pics must be mirrored?

The outputs from the gearbox are different between MQ / GQ.

As far as the winch heads go, the worm wheel and drive gear are the same size / ratios. The gear housings are slightly different as the MQ has the input shaft running the full depth of the housing and exits out the front (for a hand-crank), so you cannot interchange drivegears from a MQ into GQ or vice versa.

Freespool end and collars are the same MQ / GQ.

Winch drums are different.

There are a few options for Hydro off a GQ auto.
Change transfer case to one with a pto.
Buy a pto output that fits between the auto and the t-case, from some guy in Europe.
Sort out a second t-case as pto. (that a few people are working on at present.)
Take drive direct off the ring gear.
Belt drive off the crank pulley.
Shaft drive off the crank pulley.

I think that's all the options so far but none are bolt on.

is it true that the PTO drives off the manual gearbox rather than the transfer case in the factory safari?

yes gearbox only

drive end of a GQ pto shorter

There appears to be one exception.....Nissan Atlas / Civilian auto box has a PTO output on it with the same bolt-hole arrangement as the GQ manual box.

Howard first picked up on it and Spuddy has looked at doing it, but went crank drive off his LS1 due to cost of the Atlas / Civilian box, plus you still have the same problem with the fragility of the GQ output.

The second t-case as a PTO is simplest and most robust...give people a bit more time and it will be a winner!

I forgot about that option and I was talking to Howard about it not long ago too!
Did Spuddy actually find one of the Atlas/ Civillian boxes that bolts to a TD42?

what actually makes the GQ output so fragile? the cast aluminum output casing? Would be easy to make the case much stronger if thats the issue.

Civilian Engines:
TB45E: 4.5L Gasoline
TD42: 4.2L Diesel
RD28T: 2.8L Diesel Turbo
ED33: 3.3 Diesel
ED33T 3.3 Diesel Turbo

As I understand it, the gears are to thin.

Yup.

Its the gears that are the problem. A few people use hardened gears now as a result.

Yup.

Whats the availability of these? and I suppose the cost will scare me.

They are available, but how readily I'm not sure. The Civilian uses the TD42 in some applications, so they are definately around.

Price was a few $K, which I didnt think was unreasonable if it had been reco'd.
