Hi chaps. 4-bolt adwest steering box on my ninety. It leaks consitently from
under the top plate (lid) of the box. I have taken the top off and the seal
seems okay. Problem seems to be getting worse, drip is now a flow! Could
there be too much pressure in the system or just a faulty top seal???
BTW bought a seal kit from paddocks. The seal I want is
malformed!!!! Will returm it today if I have time.

Stew.

I find that tightening the top cover plate too much (of almost any hydraulic
system / reservoir) can deform the seal and the plate. It's one of the
areas where torque values are potentially critical.

That may be true, but the seal on the PS box is not a flat gasket type like
say a rocker cover or a water pump. It is a flat ring seal round a short
cylindrical part below the top plate. I always torque everything correctly
where possible. I wouldn't have thought it to be majorly critical in this
place as the top plate does not do the job of sealing in the fluid.

It sounds like it is just the seal. Hydraulics do wierd and wonderful
things, but as far as I can see the pump is pretty much either producing
pressure or not, so it can be lower but not higher.

Hence my vague FYI ... I just thought it might be worth mentioning .. ;)

I read that a pressure relief valve failure in the pump can produce over or
under pressurisation of the system.
