When the pump is fitted, and the reservoir full of new fluid, slacken the outlet hose on the box, and kick it over a few times on the starter, or let it run very briefly.
Put a bucket or bowl under the box to catch the fluid. Keep on topping up the reservoir, and repeat until you think it is all new fluid. Then re tighten the union, and turn the steering lock to lock a few times.
Not sure if that is an approved method, but that is what I do.
fill res, run engine keep topped up, then turn lock to lock a few times check res ,Anyone help please ?
PAS pump all fitted, at the stage of attempting what Turboman suggests so just need to confirm what it is I'm undoing.
Thanks
you cant very easily ,dont undo a hose, if you want to refresh oil put a thin rubber pipe on the slackened box bleed screw then to a container, run engine and keep toppin up res till fluid runs clean ,you might need to do a few lock to locksThanks James - I was talking about draining the system including the steering box so it's clear of any crap in there as well - hence asking about
slacking off the outlet hose on the box itself
air most likely unless belt can be seen slipping, it can take a little time,keep working itBelt too loose / tight ?
OK, all done @flat
Took a bit longer than the fella who did it on the link I used (@gstuart - legend for that !) but I took my time, stayed calm and followed the instructions.
Didn't crack the bleed box screw at all, I filled the reservoir up and turned lock to lock as we did before, maybe 20 times ? When on axle stands no noise but when under load there was but in fairness it has subsided. Have power steering Ed, yep. Feeling quite pleased with myself having done it myself but just a bit concerned about the noise.
Now I've got a pump off I may see about rebuilding it myself, but need to check what's involved first !
That’s a disco 200tdi as opposed to a defender but the principle is the same with regard to the pas pump tensioning stage using a 1/2’ socket - it’s lower down the engine on a defender and I found it easier to use a ratchet handle orientated to I could push down from above - I think I needed an extension on the ratchet though
