Power Steering Reservoir

[Tools R Us]

Got this last night off of the parted rig, thanks guys. It has netted data, so posting. The donor is a '93 FZJ80, but most Toyota reservoirs are about the same, so most observations apply.

The top is held on by tabs that are folded/crimped over, taking it off is simple, just pry up, straighten the tabs. The top is sealed by a rubber ring, this one is hard as a rock, maybe a culprit in leakage.

Inside there is a nice strainer, flow control plate. It is held in place by 3 dimples in the sidewall, quick taps with a hammer/punch flattened them releasing it.

On rigs that have been abused, the filter may become clogged. If so, would cause intake restriction, cavitation, groaning. It is easy to remove and clean.

The goal is to explore the possibility of making it deeper to reduce the possibility of sucking air at big angles. Will need some tube, the ID is 3.5", OD 3.6".

Cool disection!

Seems like the pump slurp out the bottom of the can and returns through the side port? If that is true...are you thinking of
moving the slurp hole? Could rotate it by moving/removing/replacing the side brackets.

Could add a slurp hose like aerobatic plane gas hoses. Add a weight to a hose so can slurp upside down.

Could plug current slurp location and put new slurp hole in middle? Then no air suckage on nose down or nose up attitude?

Fun project!

I like the design of the strainer, flow control plate, so will be looking to keep it. The problem is only at big time angles, so looking at increasing the depth (~2") this would also almost double the capacity.

Interesting thread from 2007 along the same lines...

Surprised no one has yet to design a suitable aftermarket upgrade. I would certainly pay to be a beta tester...

I did the cooler plan but this does not take care of the reservoir problem.


The other reservoir that Jackson shows was an option at the time but real estate under the hood is prime so I opted out due to size.

There are plenty of aftermarket reservoirs, I like the design of the stock one, most of the aftermarket units don't have the baffle plate. Don't see the need for a filter and it can cause flow issues.
