smo Posted October 26, 2008 Share Posted October 26, 2008 What is the actual difference between 3,4 & 6 bolt steering boxes?? Can i fit a 3 bolt instead of the 4 that is fitted?? Quote Link to comment Share on other sites More sharing options...
BLACK CAB Posted October 26, 2008 Share Posted October 26, 2008 The 3 & 4 bolt boxes are made by Adwest and are, I believe interchangeable. The 6 bolt box is made by Gemmer and has different hose fittings to the Adwest boxes. Quote Link to comment Share on other sites More sharing options...
smo Posted October 26, 2008 Author Share Posted October 26, 2008 So i could fit a 3 bolt happily in place of the nackered 4 bolt on my 90? Quote Link to comment Share on other sites More sharing options...
BLACK CAB Posted October 26, 2008 Share Posted October 26, 2008 I can't see different hoses listed for the 3 & 4 bolt boxes so you should be OK. I think the 3 bolt box is the earlier design, the 4 & 6 bolt boxes seem more common. Edit, I assume you are talking about your 200 TDI?

smo Posted October 26, 2008 Author Share Posted October 26, 2008 Yes for the 200Tdi Quote Link to comment Share on other sites More sharing options...
upnover4x4 Posted October 26, 2008 Share Posted October 26, 2008 I was looking at this on mine recently, ive got a 4 bolt that I want to fit inplace of my 3bolt. The mounting is the same but Im not sure about the pipe connections. The uj is different from 3 to 4bolt, so will need the latter. IIRC the splines & diameter are the same regardless of column age.

Hybrid_From_Hell Posted October 26, 2008 Share Posted October 26, 2008 6 Bolt is the weakest of the 3 I belive hoses vary on model variants between 3 and 4 bolt 3 bolt are regarded as the strongest, but will by nature be quite old now hence 4 bolts most common Nige Quote Link to comment Share on other sites More sharing options...
smo Posted October 26, 2008 Author Share Posted October 26, 2008 Thanks chaps, i think for easy and guarenteed compatability i will just wack on another 4 bolt Quote Link to comment Share on other sites More sharing options...
andyb Posted October 26, 2008 Share Posted October 26, 2008 @Smo. There are a couple of 4 bolt boxes in the workshop. Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted October 26, 2008 Share Posted October 26, 2008 One issue with the 3-bolt is that it shuttles from assisting one-way to assisting the other way so it seems to hydraulically "jam up" slightly if you saw at the wheel. I didn't like that, so went for a 4-bolt when my 3-bolt died... I think I needed new hoses too. Quote Link to comment Share on other sites More sharing options...

Do you mean if you flick the steering one way quickly then the other it responds slowly / lazily? mine (3-bolt) has always done that, i just thought it was a normal LR thing Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted October 27, 2008 Share Posted October 27, 2008 Yes, exactly that. It's worse than the assistance 'going away', mine actually seemed to 'block' motion in the opposite direction. It might have just been the heavy feel of no assistance, but the 4-bolt is much less bad. Quote Link to comment Share on other sites More sharing options...
Prith Posted October 28, 2008 Share Posted October 28, 2008 Yes for the 200Tdi What about on a 2.5 N/A, I have a 6 bolt manual and am replacing it with (thanks to one of the members) a 3 bolt PAS one. Will this work.? Quote Link to comment Share on other sites More sharing options...
crazyfarmerboy Posted November 1, 2008 Share Posted November 1, 2008 i think you cannot interchange 3 and 4 bolt one's as my friend had mansfield 4x4 to put a recon box on and it took an extra couple of days due to wrong bolt box. hope this helps Quote Link to comment Share on other sites More sharing options...
roybatty666 Posted November 1, 2008 Share Posted November 1, 2008 doesn't the 3 bolt use imperial threads where the 4 and 6 use metric and can be swapped without having to get custome hoses made up (you will need metric one end and imperial the other if you do a 3 to 4 bolt swap). I am running a 6 bolt without much issue but I can see reciepts for 3 replacement boxes in the paperwork I got with my landy which does seem to suggest they aren't that tough Quote Link to comment Share on other sites More sharing options...
Cedo Nulli Posted January 17, 2009 Share Posted January 17, 2009 Can someone confirm that you can swap a 6 bolt for a 4 bolt without changing anything to the hoses? What about the drop arm? I have a 110 200Tdi (1991) defender and my 6bolt box is seriously leaking. I wanted to replace it together with the PAS pump but apparantly it became more dificult to find a 6 bolt box. I know the 4 bolt box is stronger than the 6 bolt box. For the 200Tdi there are 2 PAS pumps depending on the engin no. What's the difference?

landkeeper Posted January 17, 2009 Share Posted January 17, 2009 but what ever connections you have at the box/on your hoses a good hydraulic hose supplier will have adapters that'll get you out of trouble , try a local agri spares place that deals with tractors/loaders etc Quote Link to comment Share on other sites More sharing options...
Cedo Nulli Posted January 17, 2009 Share Posted January 17, 2009 connections at the pump But at the box they are all the same? (And also the same as a 4 bolt box?) but what ever connections you have at the box/on your hoses a good hydraulic hose supplier will have adapters that'll get you out of trouble , try a local agri spares place that deals with tractors/loaders etc Could be a problem here, I wouldn't count on that... What about the drop arm? I'll have to use the drop arm of a 4 bolt box? Quote Link to comment Share on other sites More sharing options...
Cedo Nulli Posted January 19, 2009 Share Posted January 19, 2009 3 Bolt have different threads on the unions. 4 and 6 are interchangeable. So I can change my 6 bolt box for a 4 bolt box. It's just a bolt off, bolt on swap then? So I get a 4 bolt box with drop arm and the piping will fit? I've searched the whole internet for an answer but I never found one who told that it's possible... Quote Link to comment Share on other sites More sharing options...
