Power Steering Reservoir Replacement

[Stu NZ]

Hi All,

I'm new to the forum and thought I would start by sharing my first project on the 80 series (4.2 Diesel). Just after I purchased my truck I noticed the steering reservoir was leaking as so many others have found. So I set about replacing it with a Peterson Aluminium reservoir with more capacity.

First job was to make a new bracket to hold the Peterson tank. I made this out of Aluminium Plate and sprayed it black.

I made the bracket to reuse the existing mounting points and hold the supplied cylinder clamp.

I chose a large reservoir to help with cooling. It is 8" from the top of the cap to the bottom of the 10AN outlet. The side return port has a 6AN fitting.

I replaced the 5/8" hose and used a straight 10AN fitting to the bottom of the reservoir. In order to ensure the hose was not creased at the bends I shortened the suction pipe end by cutting it at the lower ridgeline. The lower ridge around the pipe ensured the hose still had a good seal.

I also replaced the 3/8" hose to extend it up to the new return port.

I hope the pictures and descriptions help anyone considering replacing their reservoir.

NIce write up - good looking job too!

Nice work. How close is the cap to the bonnet when it's closed? The pic makes it appear as though it's higher than the battery box.

Nice 1st post and welcome

You show how the hose terminates at the reservoir with the AN fittings how about how the terminated the other end?

Hi,

Thanks for the feedback.
Yes the Cap looks high but from a horizontal view the cap is just under the battery box (8mm) when the box rubber seal is compressed.


If you are concerned about the height of the Tank there are some on the market that are 6" giving you a little more wriggle room. (I think Canton make a couple smaller tanks).

I will get some more photos today to show the connections at the bottom.

Cheers Stu

Here is drawing of the change made to the suction pipe. I cut the pipe alone the dotted line and then used a file to clean it up. The pipe was then flushed with petrol to ensure all the swarf was removed.

The 5/8" hose (purchased as a straight length) was bent by hand into a gental 'S' shape to run from the AN10 fitting to the suction pipe (standard screw hose clamp).

The 3/8" hose (return hose) was easy to run in an 'S' shape from the standard clamp fitting at the bottom pipe to the new 90 degree 6AN fitting at the reservoir.

I hope this helps,

Stu.

Nice work, Stu!

What part number was the tank and bracket? I looked at Peterson Fluid Systems site and did not see that reservoir.
Thanks

Hi Louis,

Thanks for the positive feedback. I didn't find the Peterson website very user friendly but found the part from my local stockest in NZ. The part number is PET8-0481C8 and it is described as "Power steering reservoir 8 inch". The clamp bracket (steel strap) came with the reservoir. The black plate I made myself.

Cheers,

Stu.

This is a great mod and great work, I fully intend to do this. I have one question though. Does anyone have any idea how this PS 8" reservoir would work in conjunction with the "Mr. Gasket 7365G Satin Aluminum Dual Pass Transmission Cooler"? I would think the more fluid the better and less chance for any overheating, but don't want to over do it either.

Appreciate any feedback anyone has on the subject and thanks to all those who have paved the path as well.
Cheers,
Tim

Very nice, welcome

Nice write up and pics, welcome to mud!


This is probably a dumb question, but are there quantifiable benefits to an oversized reservoir for power steering fluid?

Does this put more/less stress on the pump and system?


Always looking for ways to upgrade the ride, so excuse the ignorance!

Good job!
How much is the Peterson tank selling for?

 

[Stu NZ]

Hi, It is my understanding that the more fluid the better because the heat from the steering system is disapated by the fluid. Therefore the pump should run cooler. I'm not sure how much longer life you will get out of your pump but it should help.

My main driver was the cost. The Toyota reservoir is $800 (NZD) and would crack like the original. The Peterson tank, AN connectors and hose all came to $248 (NZD) so it was an obvious choice.

Cheers.

Are you sure Toyota reservoir selling at NZD $800??
We get it here in Malaysia about RM480 which is about NZD $197.

Price was from Toyota. I found a couple of websites over the water that sold them but they wouldn't ship to New Zealand.

Who was your "local stockist" that you mention getting it from? I am in Auckland
