Im changing the power steering pump in my car, my only problem is I can't undo the gold bolt that screws into the pump (holding the valve section?). I need to take it off so I can remove the valve(?) and the section of hosing attached to it from the old pump and reconnect it to my new pump.

thanks,

The r32 gtr and gtst use the same pump. Its the suction

pipe, and a bracket for one of the hoses is all that is different between two. They mount and adjust the same too.

Its under the pump from memory, 1 bolt or nut as a lock, then another to put tension on the belt.

I have'nt studied the internals yet, but the pulley size is the same. I need to look inside to see if one flows different than the other. My guess is that they are (flow) the same.

Before you do this check your power steering belts tension and remember this. From memory the book states it should have 9-15mm of deflection at 10kg of pressure? So if you push it down with your finger it should roughly move about 1cm.

I just undid the long bolt at the top which holds the PS pump to the engine bracket. I couldn't take this bolt right out at this stage as the pulley holes werent lined up with it. Then I ended up undoing the whole tensioner assembly (2 bolts on the left and one in the middle). Now you can pull the power steering pump down so it's closer to the engine side creating more slack in the belt so you can now remove the belt from the pulley. Rotate the pulley now (as it can turn freely) if need be to line a hole in the pulley up with the top bolt. Remove this long bolt and now you can remove the power steering pump from it's bracket as it's no longer held in by any bolts. I didn't know a good way to drain the power steering fluid so I just took off the hose at the back of the pump and just let the fluid drain out, this is pretty messy so I put lots of newspaper under the car as I didnt have a jack and I couldnt get a oil pan to fit under my car.

Now for the part I had some trouble (took me 2 days because of this), the gold bolt that attaches the hose at the top of the power steering pump. I found this impossible to get off with a shifter but after purchasing a 15/16" socket the next day I was able to eventually get the c*nt off after a few goes. I'm not sure if they're all this hard to undo but I would suggest using a socket wrench as it worked for me!

So after you undo this bolt (btw mine had a washer attached underneath the hosing) you can remove the hosing that it was holding and begin putting your new power steering pump in!

Mine was already clean but if your new pump is looking a bit gritty it might be best to spray some degreaser on it and then give it a hose down before putting it in.

Make sure you do the belt backup to the same tension.

When you've put all the bolts back on (make sure you remember them all) and adjusted the belt tension correctly you can start filling up the resorvoir with PS Fluid. I used Valvoline Formula F Power Steering Fluid ($10 for 1L at Supercheap), it says it specially designed for Ford Falcons or something which had me worried but my mate said he uses it in his WRX and he hasn't had any problems so I went with it. Yeh so just topped the resorvoir up till it registered full then started the car (with the PS resorvoir cap off) and turned the steering wheel lock to lock (this apparently gets rid of air in the system). The car was making an awful sound that you do not want to hear your car make. I checked the fluid and it was down so I topped it up again (air loss and the fact that the hose lines would be empty I guess). Ran the car again and the awful noise was gone so I think the noise was just the pump running dry.

Took the car for a test drive and it seemed fine and havent had any problems with it yet (touch wood).

This is the first time I've done this and I probably made a few mistakes so dont take what I've written as gospel but it worked for me and might give some people a rough idea of what to do if they dont know.

Good guide, just a couple of things....

everything on a line is metric, the big bolt is either 23 or 24mm not 15/16ths

Undo the bolt while the pump is still bolted in place it should be easier since it will sit still. Be really careful with the bolt it has fluid running though it so it can be weaker than a normal bolt.....no wacking with hammers.....

are you talking about the left gold bolt?

is the picture below, the 2 bolt you're talking about? and the last picture, is that the bolt for the tensioner?

In my pics (see attachments) the bolt circled in red is the bolt which holds the power steering pump to the engine bracket. You need to remove this bolt.

Circled in yellow are the 3 bolts holding the belt tensioner assembly. Two are on the left and the other is in the middle, directly below the bolt that holds the PS pump to the bracket (circled in red).

Shown in blue is the adjuster at the end of the tensioner assembly. As you can see the previous owner had a nice washer and nut collection going on mine lol. This usually adjusts the tension of the belt but since you are taking the entire assembly off there is no need to adjust it to remove the belt.

So you need to drain fluid (i removed the hose at the back of the pump), remove large bolt holding top hose. Remove pump by taking out 3 tensioner assembly bolts (shown in yellow) and remove long bolt holding ps pump to bracket (shown in red).

Thanks Duncan, sorry guys but I did use a 15/16" socket and it still worked but then again I wasn't concerned about wrecking the bolt as one came with my new pump hehe, try to use the correct metric size.

Also as Duncan mentioned it is probably easier to remove the big bolt (the one that holds the top hose on) with the PS pump still in place.

Make sure when you put the new pump in you put all the bolts, hoses etc back on.

If you have anymore questions just ask.

Good luck.

i see that your pictures are a bit different from a r32, but is almost similar.

It seem to be easier on a r33, because on the r32, my tensioner bolt is in my last picture, and it is underside of the powersteering which is hard to reach.

I will only replace my belt, so i wont do the whole step, but it is a good write up for someone else

thanks

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Maf is a question mark but TPS  I have set at 0.47, the fact that I’m getting proper voltage range out of it with the key on leads me to believe it’s functioning properly. I’m getting proper voltages on basically everything. I still need to look up voltage ranges for z32 maf and test that

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Honestly no not at all, but it’s a very basic tune, it’s stock injectors q45 tps and z32 maf. Other than that it’s a completely stock base map. The file is from nistune and from my understanding if it was tune related I would be able to unplug maf and tps and it would still start even if it was a really shitty start. I have tried starting it with coolant temp, maf, and tps unplugged none of those 3 togethor or individually changes anything

      What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day   Highway gets as low as 10l/100km on my end so I'm not as worried about it being a mechanical issue. More likely just the tune on the haltech.

      RH9 R32 GTR Build Thread

      By OST Micah · Posted

      While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
