ZF Steering box clamp torque setting

#1 Post by Tim Splaine »

Hi guys, I'm just putting my reconditioned steering box back on my 1959 T5 and don't know what torque to use for
1) The aluminium clamping bracket, I don't want to snap the thing.
2) A value for the tie rods. looking back at some threads it looks like 30lbs is good but also mentioned that this maybe too much. Just a pinched up because it is on a taper shaft?
3) Steering damper, I guess this is the same as above. Also does the damper fit below or above the Pitman arm. I took some pictures before dismantling but not the ones I need :-( I think it is below.
4) Steering shaft to box 4-off castle nuts (You know rubber boss connection ones).

Thanks guys. Tim, Bristol UK

Tim, there is this reference list on the website.

Thanks Dave. Nice to hear from you. I found a GA showing the damper arm above the pitman with bolt going down so one question answered. I'll look at the link tomorrow as it's late here and can't follow guides on my phone.
Cheers again Dave. Tim

Additionally Tim, the tie rod ends originally came with castellated nuts so again no specific torque because properly secured they can't come loose.
New ones have nylock nuts so again just tight should work.

Hi Dave. The link isn't working for me. It's the aluminium clamp I'm worried about. Would you have a value for that so I don't snap it by over tightening?
Thanks, Tim

Don't be too concerned Tim. Just tighten it to maybe 30 ft/lb and bend the locking tabs over. I'm sure that will not harm anything and if you did break the aluminium clamp I will send you another one for free and I will pay shipping. Just be sure it goes down evenly.

Thanks, Tim
