Power Steering Fluid Level on '66 Toro

[Otto Skorzeny]

Where is the level supposed to be for the Power steering fluid? The cap has no dipstick and there are no marks on the pump reservoir.

Neither the owner's manual and the FSM tell what the level should be. They mention total capacity but that's useless unless you're starting from empty. All the FSM says is to check it while its hot.

Doesn't anyone here know the answer to this question?

The pump housing is just a bucket (or reservoir) around the pump and seals with a retaining ring. I just take the cap off and make sure I see fluid at the top, and that is the correct level. Not very exacting, I know. The ps return line is at the top, while the high pressure is at the bottom. Looks like they went to a type of pump that has an actual short filler neck on top and cap with a mini dipstick by 1969 (could have been 68, not sure). That dipstick doesn't even quite extend to the bottom of the filler neck, so that indicates level of oil right at the top. Just be sure you see fluid at the top when you take off your cap, and you're fine. That bathes the entire pump in oil. these are not that complicated. If yours is leaking, order a kit, take it off the car and rebuild it. Then you'll understand. Pretty simple design. The pump is essentially a rotary vane pump.

When you say "top", Top of what? Not top of the filler neck?

Top of the round reservoir aka bottom of the filler neck?

Also, do you check it hot or cold?

Otto,

Here, look at this link and picture. Don't drain fluid like one suggests and then put the amount back in as stated in FSM. Just look for the oil level at the top. As you can see, the oil level in the first picture may be a little low, but now much. The return line comes in at the topside of the housing, the pressurized part is on the "groundside" of the housing. Not complicated. If you pump is leaking or steering gear, you will see that on your car and know that you will eventually have to service some or all of these parts.

BTW, according to this post, they went to the little dipstick in 1968. 1966-67 power steering pumps are likely one and the same, as is the steering gear.

[Otto Skorzeny]

Thanks. That's virtually the same scenario I have. Without a dipstick I just guessed that it should be halfway up the filler neck like my F100.

Nope. It blew it all out the vent hole in the top of the cap.

I'll keep it to the bottom of the filler neck cold.
