TB42 power steering pumps

Joined: 25 Oct 2003 Location: Melbourne Australia

Does anyone know if the TB42 had any power steering pump options over the years? I've got an opportunity to get a very nice hydraulic winch but from what I can gather, it sounds like I'll want improved pumping capacity.

I could just try fitting a smaller pulley to increase the flow, but I just thought I'd check whether there was an easy retrofit anyone knew of.

Also, is there an oil cooler inline with the standard setup? If not, I might try squeezing in a trans cooler.

Any tips appreciated. Also any positive/negative comments about the Ox hydraulic winch wouldn't hurt before I buy it.

The OX will run all day, but slow in std form. Speak to some hydraulic experts for some tech advice on uping the speed. I have some 3ltr pumps and a TD27 pump that uses a remote tank so I guess you could make the tank as big as you need for higher volume to run both power steeer & winch. BUt for speed you may need to speed the pump up with a smaller pulley but I don't how that would effect the power steer if at all. Probably just bleed the excess past it perhaps. Maybe you could mount the extra one for the winch alone? I haven't got to that stage yet but I working on it. I got the pumps with the remote tank to make way for the supercharger. Probably not much help for ya at the moment but i'll see what i can find out

Cool. I'll see how I go... I mean it's not like I plan to be using the winch that often; it's more of an emergency item.

I figure that with a low-revving engine like a TB42 putting a smaller pulley on the pump should be fine. I did the same on my jag which sits on 6500rpm happily and no harm was ever done; and the V12s just use a standard GM pas pump. From the pump's point of view it's exactly as if the motor were just running a few hundred rpm faster (or even a few thousand - either way, it can probably handle this.)

I'll keep you posted too - heck, I haven't even bought the winch yet. Basically I got offered 16 (yes, sixteen - 12 MT and 4 AT) BFG 285/75R16 tyres on GQ wide rims plus bull bar plus brand new 10,000lb ox winch for a... reasonable price.

Guy had some bad luck with hail and doesn't have a GQ any more.

Just gotta find the dosh to take it all off his hands.
