G'day all.

I'm trying to hunt down an image of how/where the brace from the power steering pump to the engine mount, mounts.

Can anyone help me out, please?

Car is a HQ Ute. Red 202.

Grabbed this one off eBay and it arrived today, but have no idea on its correct position. Isn't the easiest thing to line up.

http://www.ebay.com.au/itm/1807...trksid=p3984.m1439.l2649


Have had major leaking issues since installing P/S nearly 2 years ago. Tried everything. Rebuilt the kit twice & changed the hoses twice. No change. Replaced the lid. No change. Nothing leaks when stationary, and none of the hoses/joints leak under revs at full lock (was told this is sometimes an issue because of the pressure build up).
Have been informed recently about the pump-to-engine mount brace, which I didn't have installed (and had actually never heard of or even seen before). Was told that without it, the pump actually shakes - worse the higher the speed - causing the fluid to come up & out through the lid.

This makes sense in my case. If I'm driving casually doing no more than 60kph everywhere, I'll only need to refill the reservoir twice a month. If I'm constantly doing high speeds, it's much worse. Last week back & forth on the F3 I had to fill it up 3 times. Wasn't just a top-up up either. Every 2 days it was dead empty - with fluid all over the drivers side of the engine bay.

In the pic.. Top LH is the end the bolts to an engine mount. The other one bolts onto the stud in the back of the pump.

Take out the engine mount bolt (the one that bolts into the block) and you should be able to see how it all goes together.

Still stuck.. check out any VB, VC 6 cylinder power steering set up. All exactly the same as your HQ 202.

Hope this helps.

There was a modification a lot of years ago to stop the fluid leaking from the cap under the circumstances you described. It involved fitting a diaphram to the dip stick on the filler cap. This was enough to stop the fluid hitting the underside of the cap and leaking out. What happens instead is the fluid hits the diaphram and falls back to the resevoir. Might be worth looking at??

What you describe is how all the later (80 onwards) caps were made, but even with the splash shield fitted it will always lose fluid if the rear pump brace is not fitted.

You may have a V8 pump, that does not have a stud on the rear of the pump.

Commodore 6 cylinder pumps are not that rare, but you will need a WB presure hose if fitting a metric pump.

i haven't taken one off for quite a while, but i remember something about two specifically longer bolts that go through the timing cover, that are particular to 6 cylinder timing cases with PS
Old holdens brought on the spot, quick decision, cash paid.

Thanks for the info gents. I'll have a crack this arvo and see how it goes.

Just for clarification, here is a pic of the back of my reservoir:



Does the brace go behind that bottom bolt or is there something missing?

Cheers.

What you have there is an HQ-HZ V8 pump.

As Warren has said, the rear stud is probably missing & that's exactly it. That stud is the only difference between the 6 & V8 pumps in those models.

The lower rear bolt has to be removed & replaced with a stud. It is not just a normal stud, it's more like a double-ended bolt. It screws in where the lower bolt is now located & is tightened. The remaining protruding threaded stud is what the strut brace is attached to.

Be careful, these older style pumps (pre 1980) have imperial threads, while the later style pumps use metric threads. You can't just take one from the more common (Commodore style) pump & screw it in to yours. Make sure you find the correct 5/16" UNC genuine stud, they are getting hard to find nowadays.

Terry,

Can you remove that bolt with the pump together, ie is there a possibility that something inside will fall out?

Thanks for the info Terry. I did some looking around, and jacked this image off of eBay. This is the stud you are referring to?

Yes you can, it's only a blind hole, nothing will fall out.

The only thing to watch is not to damage the small o-ring seal between the canister & the pump case.

From memory the bolt that the strut goes to on the engine mount adapter to the block, it is longer for the power steering application.
