smokin'joe Posted June 10, 2015 Share Posted June 10, 2015 ok, so i have bought a certed 2-door flat deck vitara for our Catlins block clearing mission. i need to make the deck tipping, as there is no other suitable position for the spare wheel apart from a cradle above fuel tank, and there isn't enough room to slide it under deck. options are: 12v pump/resiviour off small taillift/wheelchair hoist , engine driven pump struggling to find a 12v unit cheaply, used to give these away 5 years ago !!!, so engine mounted could be next cheapest option. if it is engine driven, can i replace existing P/S pump and run steering on hydraulic fluid as opposed to ATF ? alternatively , would a P/S pump provide enough pressure to run a small hydraulic ram or 2 ?

Mof Posted June 10, 2015 Share Posted June 10, 2015 You could still use atf. And what about one of those exhaust airbag jacks? I've seen trailers use those for tipping. Quote Link to comment Share on other sites More sharing options...
smokin'joe Posted June 10, 2015 Author Share Posted June 10, 2015 airbag not suitable, as i want to run auxillary rams later....... if i go hydraulic. will get it hinged for a start so i can mount spare wheel, but it really needs mechancal tipping as will be doing plenty of firewood etc with it, as i am clearing broom,blackberry, bracken etc Quote Link to comment Share on other sites More sharing options...
Ogre Posted June 10, 2015 Share Posted June 10, 2015 ATF is fine to use as a Hydraulic. In fact its better.Its what we use for high heat and loaded hydraulic systems. Can you use the power steering pump im not sure, but tipping a flat deck with wood on it wouldn't be to hard for a hydro system surely?

CaMpylobacter Posted June 11, 2015 Share Posted June 11, 2015 smack a hilux/hiace p/s pump where the a/c pump would usually be. I say hilux/hiace coz heaps of 4wd rally guys run them and they can be mucked with easily. they're not too hard to get hold of, have a remote reservoir and seem to be fairly reliable in that application so should run a small tipper reasonably ok. lots of dudes in the 4wd circles use them to run full hydro front steering and a steering ram on the rear. often at super low and high revs, and they require high speed reactions so it's much more demand than a tipper would ever be, are you wanting it to be tipping just so you can have a spot to chuck ya spare wheel that's not on the deck itself? that's how i read your post? if so, perhaps a low profile roofrack to chuck it up on would be the go? not ideal if you get a puncture and have a load that you need to tip off the deck to get at the spare Quote Link to comment Share on other sites More sharing options...

Steelies Posted June 11, 2015 Share Posted June 11, 2015 bugger, just scrapped a tail-lift pump i couldnt give away for years! does anyone know if P/S pumps are good for heavier duties, generally being a vane type, as opposed to gear type tailgate pumps? http://www.trademe.co.nz/motors/trucks/tippers-sliders/auction-898336595.htm Quote Link to comment Share on other sites More sharing options...

I know vanes can give some good pressure , but id rather put my money on a nice gear pump and be nice and safe tbh. I couldnt tell you were to find one for cheaps though .

Gomaxgo Posted June 11, 2015 Share Posted June 11, 2015 this thread is relevant to my interests. What about the generic GM pumps? cheap as chip to buy new and pretty heavy duty, run PS and power assist brakes on heaps of big trucks Quote Link to comment Share on other sites More sharing options...

Gomaxgo Posted June 11, 2015 Share Posted June 11, 2015 belt driven off the engine. As far as i know they are a vane type. Have replaced heaps due to leaking around the main seal ( 30-50 year old chevs so understandable) but so far only seen one properly break when it snapped the main shaft, which was on a late model 2500 silverado 1 Quote Link to comment Share on other sites More sharing options...
Steelies Posted June 11, 2015 Share Posted June 11, 2015 ok it's mega low budget styles. ^sounds lush, would be keen to see one of these gm things tested! do they have clutches like AC? what size ram/s have you been looking at? another big factor in how it'll load the pump and your wallet Quote Link to comment Share on other sites More sharing options...
smokin'joe Posted June 11, 2015 Author Share Posted June 11, 2015 ok it's mega low budget styles. what size ram/s have you been looking at? another big factor in how it'll load the pump and your wallet it dosn't need to be super high spec, as the deck is only 1050mm long, and the pivot point will be approx 250mm from end, so there is only about 80% of total weight being lifted (400kg if wet wood). the deck only needs to be raised 450mm-ish to get it past 45 degrees, so if it is on a scissor-type underbody lift, ram would only need 250mm of stroke, or 500mm if direct acting front of body. going to have a look at some rams this morning and have a chat to a couple of system designers, so will report back. fucken 'puter froze on me last nite whilst bidding on an old hospital bed that had been used for M/Cycle repairs, manual pump, but remote ram, could have worked, if not could have used it for the aux ram i want to employ.

Steelies Posted June 11, 2015 Share Posted June 11, 2015 would it be worth just rolling hand pump re-purposed jack stz? Quote Link to comment Share on other sites More sharing options...
smokin'joe Posted June 11, 2015 Author Share Posted June 11, 2015 would it be worth just rolling hand pump re-purposed jack stz? only if FOB mounted, otherwise be knuckle-smashingly cunty to pump up. ideally mechanical or electric pump so i can add another aux ram and diverter valve later for additional duties. push comes to shove i can use a boat winch or a manual ram, but i do like the idea of in-cab control 1 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted June 11, 2015 Share Posted June 11, 2015 Why not t into your power steering system and just increase resivior size. I hear factory PS systems often reach over 1000psi. It might be slow but who cares? Will be faster than a hand pump! I fail to see any downsides and it'd be easy as fuck to.implement Quote Link to comment Share on other sites More sharing options...
