robhybrid Posted March 7, 2007 Share Posted March 7, 2007 I am contemplating having a go at making my own kit out of some second hand bits but where exactly do I tap into the power steering box? Any one done it? Got any pictures? Quote Link to comment Share on other sites More sharing options...

robhybrid Posted March 7, 2007 Author Share Posted March 7, 2007 Had a look on pirate couldnt see any pictures of a tapped 4 bolt land rover box. Thing is I know I have seen it on the net somwhere but I cant find it now. Already had a go drilling and tapping a scrap 4 bolt box and didnt have any problem on clearance from inernal gubbins but I am a bit concerned about potentially wreking a 6 month old steering box. Another thing is an aluminium end cap going to be strong enough to hold the thread of a 1/4" bsp fitting without stripping when under hydraulic pressure?

Paul Humphreys Posted March 7, 2007 Share Posted March 7, 2007 Try looking on www.straightforwardsupplies.co.uk as they use to do them. Paul Quote Link to comment Share on other sites More sharing options...

SOA 93 Posted March 7, 2007 Share Posted March 7, 2007 I bought a Straight Forward S.. ram, have not fitted it, and would not recommend you buy one. Its a 40mm piston with a 200mm length cylinder you could source one alot cheaper yourself, it comes with some drilled plate and a couple of big bolts, no bushes of any description. Rakeway make one, slightly smaller piston IIRC but comes with rod ends, niiiiiiice. Rakeway will covert your box they just drill and tap either end of the main cylinder, one end of which is the blanking plug, sounds like that is what you've already done. If you want some reasurance or advice give Rakeway a call. I'm hopefully going to get the ends of my ram machined to take Panhard rod bushes.

smo Posted March 13, 2007 Share Posted March 13, 2007 At risk of sounding really thick - why would one want to do this? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted March 13, 2007 Share Posted March 13, 2007 The clue is in the name - hydraulic assist it uses fluid pressure from the steering box to move a hydraulic ram connected to the steering arm, adds assistance / takes load off of the stock steering box.

roguevogue Posted March 13, 2007 Share Posted March 13, 2007 While I don't give a damn. I didn't tap the box as such, I took the top off the box and opened out the bleed screw hole, the other fitting I used a hydraulic compression fitting into the pipe which runs around the outside of the box. This removes the need to remove the box from the chassis at all. Quote Link to comment Share on other sites More sharing options...

Yep - you'd be surprised how easily you can twist / shear a sector shaft and how heavy the steering can be when running big tyres. Quote Link to comment Share on other sites More sharing options...

This removes the need to remove the box from the chassis at all. Dave Lama is sorting me out some fittings so that in theory I dont have to modify the box at all. Although I am tempted to slightly open up the hole in the bottom of the bleed screw hole but I am temted to try it first. Quote Link to comment Share on other sites More sharing options...

I have twisted a shaft in the past so have a number of other challenge competitors that I know. I am hoping that this will be a solution.

So a secondary system to normal power steering then, but using the same pump for fluid? Quote Link to comment Share on other sites More sharing options...
robhybrid Posted March 13, 2007 Author Share Posted March 13, 2007 Yes same pump for fluid. Quote Link to comment Share on other sites More sharing options...
