Hello all, Ive been lurking around this site for a few years, but for a couple of weeks Ive been unable to log in on my old user name so Ive re-registered .(Hope thats not against the rules). Ive never had to ask for help as all my problems have been sorted with the search button .Ive recently retired so I may have time to finnish the avon. Thanks for all your help, izzy

Any subject eh! How about this. Ive just bought a Renault commando G08 horsebox.There seems to be exessive play in the steering,I am told that this is correct(6"at the steering wheel) Anyone got any ideas

Renault.....hmmmm French....yes que intake of breath through pursed lips (hssssss) that'll be normal then.....Oli.

Sounds like the reins need tightening?

Steering box requires adjustment - belated welcome

Steering box ok. The arm from the box acts on some sort of servo valve which operates the power assisting ram. The play is from this servo valve which I am told is normal,but it still feels strange at 60mph. izzy

I've no expierence of Renault trucks but the principle on which the system I think you have is that the play is there in the valve so when you turn the steering wheel the movement pushes the valve open before you get as far as actually moving the wheels. As the ram moves the linkage it lifts the load off the valve & the movement stops unless you keep moving the steering wheel.
However you only need enough play to open the valve, 6" at the wheel sounds a lot. Is it not a maximum of 3" at the rim edge for cars with a steering box for the MOT? HGVs might be different anyway.

Give that man a cigar,youve got it in one,Now any ideas on taking some of the play out. Iwish I had a workshop manual, Any HGV fitters out there? izzy

Sorry I cant really help, I see a few old 7.5 tonners that farmers use but most seem to have the setup all in the steering box without a seperate ram. It may have something like a tapered pin & hole adjusted with shims or a locknut.
I hate the things anyway, I'm much happier with a tractor!

Tractor! Now youre talking. Id much rather be working on my old T20
