You're posting here so you have internet access. You can't look up the service manual for your bus online? Cars get pretty fancy with their requirements hence why there are so many choices on the shelf.

The Blue Bird manual calls out damn near 57 different fluids, all being considered acceptable. They list 10W40 oil as possible transmission fluid even. The manual comes with a note:

Put only brake fluid in the brake fluid reservoir and power steering fluid in the power steering system. Failure to use proper fluids could result in loss of braking or steering.

Another note it mentions: Crank engine several revolutions. (Do not
start engine
.) Check pump reservoir and
refill if necessary.


Which contradicts another section: Note: Start the engine and let it idle for 5 seconds repeatedly until the fluid level remains stable. This will purge air from the system.

Approved Hydraulic Fluids
! Automatic Transmission Fluid Dextron II
! Automatic Transmission Fluid Type "E" or "F"
! Chevron 10W-40 Motor Oil
! Chevron Custom 10W-40 Motor Oil
! Chevron Torque 5 Fluid
! Exxon Nuto H32 Hydraulic Fluid
! Fleetrite PSF (Can #990625C2)
! Ford Spec M2C138CJ
! Mack EO-K2 Engine Oil
! Mobil ATf 210
! Mobil Super 10W-40 Motor Oil
! Premium Blue 2000 – SAE 15W-40
! Texaco 10W-40 Motor Oil
! Texaco TL-1833 Power Steering Fluid
! Union 10W-40 Motor Oil
! Union 15W-40 Motor Oil
! Unocal Guardol 15W-40 Motor Oil

I'm going to be fairly bored today. Give me whatever you know about your bus (make, model, year, any part numbers you have for the steering pump, etc.) and I'll see what I can find.

1500 lbs pressure is only on the supply side of the Power steering system, and that side will have hydraulic hoses.. the return side is usually very low pressure... after all the concept of pressure in the first place is that the flow is restricted enough that the pump can put force on the fluid.. so the return side is natrually much lower pressure.. thus why the return line is often standard rubber hose with hose clamps..

I have a parts manual from Thomas. Of course all proprietary numbers. So no use The bus is not supported anymore by Thomas freightliner.
It is a 2004 Daimler Thomas freightliner slf232 . it has Mercedes 6.2 liter diesel mbe906la. 300hp.
Hydraulic pump and air compressor are integrated with the engine.

Looks like the steering pump is a zf

Don,t worry. i knew this bus was a difficult one to keep on the road. But we are still running. This bus has a long history for us.

We overnighted at a wally west of Atlanta. It was pretty cold and I got scolded by the family that I did not turn the heat on. That was of course after Smita cooked a very nice dinner using both inverters and both induction stoves. ( while I was napping ) . I woke up because the low battery alarm on the inverter started beeping. The engine was still warm and the bus started fine. Anyhow after some idling and driving I decided not to turn on the overnight heat.

Spend some nice time at the Alabama border in the visitor center and outside with Rosie. Later at the bass pro having fun at the shooting games. Smita cooked while we were driving so plenty of juice.
Now we are a wally / Lowe's just inside Mississippi. Bought some parts to see if I can get the water pump/ tank hooked up. Heat is on all is good.

Drive safe and be careful. There is a forecast of rain and colder temperatures (all above freezing) in the Dallas/Fort Worth area all day tomorrow (Friday the 11th).

Thanks native. We are not traveling that fast. Hanging now 50 miles east of Dallas. If I feel brave I will try to get up at 1 in the morning and get beyond fort worth during the night.
