stripy Posted March 26, 2010 Share Posted March 26, 2010 hi i have just changed my power steering pump and i am having trouble getting it bled i have undone the bleed nipple on the steering box and let it run for atlest a couple of minutes but still the steering is very heavy, what have you guys done to get it bled Quote Link to comment Share on other sites More sharing options...
LandyManLuke Posted March 26, 2010 Share Posted March 26, 2010 As you've been doing, but jack the front of the car up so both front wheels are off the ground. Cycle the steering from left to right. Quote Link to comment Share on other sites More sharing options...
white90 Posted March 26, 2010 Share Posted March 26, 2010 Try to avoid full lock though unless you have a tube fitted to the bleed nipple Or you'll experience a power steering fluid fountain as it hits the bonnet then covers anything in front of the car.

stripy Posted March 26, 2010 Author Share Posted March 26, 2010 right iv'e been turning lock to lock for a couple of mins..... still no joy bleed nipple is giving a good flow with no air bubbles showing anything else i can try Quote Link to comment Share on other sites More sharing options...
old leafer Posted March 26, 2010 Share Posted March 26, 2010 make sure the belt is good and tight it can be worth liffting the wheels of the ground and dropping the steering arm then turn the wheels incase it is a prob in the hubs regards mark Quote Link to comment Share on other sites More sharing options...
JST Posted March 26, 2010 Share Posted March 26, 2010 i take it the new pump was fitted as that was diagnosed as faulty?? or was it just leaking? IE is what you are experiencing now the same as prior to fitting the new pump? Quote Link to comment Share on other sites More sharing options...
stripy Posted March 26, 2010 Author Share Posted March 26, 2010 the old pump had a lot of play in it, so much that i could not tension the belt propley, the old pump was ok on road, but i use the ol'e girl for comps so i didnt want it to let me down , so it must be air, as all was fine befor the change.

white90 Posted March 26, 2010 Share Posted March 26, 2010 Try cracking the pipes one at a time with the engine off to check fluid is getting around then try bleeding again Mine was dead easy after a I cleared up the mess from above Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted March 27, 2010 Share Posted March 27, 2010 Trying to do the same with mine now after changing the pump this morning. Can't get it to work! Opening the bleed screw produces a steady flow of bubble-free liquid. Tried the same with the front wheels raised and cycling the steering lock to lock a few times, no appreciable difference in flow and no more bubbles that I could see. I cracked off the pressure feed union going into the box, accidentally undid it too far and the pump duly emptied the system onto the floor in the time it took me to scramble into the cab to turn off the engine. So it's certainly pumping fluid. Any ideas folks? Quote Link to comment Share on other sites More sharing options...
errol209 Posted March 27, 2010 Share Posted March 27, 2010 Any ideas folks? A very persistent air bubble? Usual health warnings apply, no responsibility etc., but how about giving it some "loud pedal" and repeating the lock to lock bit? (I've never had this problem, by they way) Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted March 27, 2010 Share Posted March 27, 2010 Yes, that's probably worth a shot. I've let it settle for about an hour now, will head back down the workshop and try some more cycling of the steering with the front wheels raised. I hope I don't run out of ATF Quote Link to comment Share on other sites More sharing options...
JST Posted March 27, 2010 Share Posted March 27, 2010 in the time it took me to scramble into the cab to turn off the engine. Any ideas folks? yep - pull the stop solenoid wire. Back OT, with mine i leave the wheels on the ground. start her up, bleed in the straight ahead position. close bleed nipple, turn her full lock one way then the other way holding her there for 20s or so (just back from actual full lock) then put her back to straight ahead and bleed again until she runs clear of air. easiest way to tell is with a clear pipe on the nipple so you can see whats happening. i also take the viscous off first to save my sleeves!

Retroanaconda Posted March 27, 2010 Share Posted March 27, 2010 i also take the viscous off first to save my sleeves! I have no viscous fitted so at least that part is easier I have sorted it now, sat in the cab and gave it some beans while cycling the steering. It then started making that straining noise on reaching full lock and upon lowering the wheels to the ground for a test drive all seems to be well. I think all the air is out of the system, but I will take my bottle of ATF with me to Hogmoor tomorrow anyhow Thanks for the help guys, it's lovely having properly effective power steering again. Coupled with the discs on the rear, it's a different car to drive! Quote Link to comment Share on other sites More sharing options...
stripy Posted March 27, 2010 Author Share Posted March 27, 2010 bled mine again today.......still got air in it somewhere, going to take it for a good drive then have another go......perhaps with beans this time Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted March 27, 2010 Share Posted March 27, 2010 For what it's worth, it took about five minutes of constant lock-to-lock turning, periodically giving it a bit of a rev, on mine before it suddenly just went. Must have been a big bubble trapped somewhere as errol suggested above. I went for a test drive to try and get the system to self bleed, turning round in the fuel station was a horrible experience without the PAS on a steering setup geared to have it Quote Link to comment Share on other sites More sharing options...
stripy Posted March 28, 2010 Author Share Posted March 28, 2010 just been out for another bleed let me tell you my findings, the motor is on axel stands,the hand throtle set to a very quick tickover, clear pipe from the steering box bleed nippel to the reservoir , wheels in the stright ahead , now im standing at the offside wheel holding the the pipe over the reservoir with a good flow...turning the wheels with my knee's i am still getting flow but not so good , when i get on full lock very small flow, when coming off full lock flow stops and even creeps back a bit, back to center good flow. this happens on both locks is this air .............or is my new pump u/s cheers john Quote Link to comment Share on other sites More sharing options...

Milemarker Type S Posted March 28, 2010 Share Posted March 28, 2010 I have had exactly the same problem as this twice when fitting a new pump to a friends truck... on both occasions the issue was down to a fault with the new pump- both genuine parts from a reputable dealer. I managed to track the issue down to a tiny pin prick hole in the outer casing where it had been spot welded together- it was letting air into the system so try as I might- and god did I try- I just could not shift the air out of the system. Both were exchanged for replacements without any question. Si Quote Link to comment Share on other sites More sharing options...

Retroanaconda Posted April 21, 2010 Share Posted April 21, 2010 I had a Britpart boxed PAS pump and I was assured by the people at Brit-Car that it was OEM. Quote Link to comment Share on other sites More sharing options...
