Power steering fail, leaking tranny fluid
It was running so good…
and then hen the power steering went and the trans temp jumped. Gonna try to hobble up to a safer place and get some fluid in.
Is there a blow off for the Tran fluid or might we have blown something?

It’s an ‘89 H5-60

8 v 92 ? ck passenger side of motor toward front of bus toward edge of oil pan. If it is power steering there is a leak there it will be O-ring blown on pressure relief valve. Will be about 1 inch in diameter with a 1/8 pin retaining it. Less than 5$ fix but shop will sell you a 5-600 $ pump.

This is the unit that’s leaking. We suspect the pinkish fluid is steering…?

Sunday.Thanks, Milo

Everything looked good so we left this morning. We’re in Mt Shasta. We’ll need to tow it tomorrow. Hopefully somewhere in OR where we can fix it. But may have to wait til Monday cause AAA needs a destination.

Okay. So.
I left SF with my engine and tranny temps at about 170, and they both got up to and stayed at about 190 pretty quick. I didn’t see normal operating temps in the manual but I drive a duck with a Detroit and an Allison tranny and the operating temps are between 180 and 220, so I thought we were pretty good.
On the third big incline it started to lose power and then I lost power steering. As I was pulling over, the tranny and engine temps jumped up and the whole thing shut down. Trans read about 210 and engine was about 200.
After a bit, everything started up and the only loss is the power steering.
If anybody knows a place in SO Oregon we can bring it to to get this fixed, we’d be mighty obliged..

Hello, there are Freightliner truck shops in Redding CA and Medford OR that will work on Detroit Diesels. You may be able to find a mobile mechanic that can come to you. Have you taken a mirror and looked at the back side of the 90 fitting?
Mt Shasta is a beautiful place.

There are worse places to be stuck, for sure.
So far, I’m thinking getting towed to Medford is the smartest thing.
Maybe that means laying low for a day and watching the Seahawks beat the Raiders.

On my first leg in my 1984 Liberty, I had a power steering hose burst. We fixed it (twice), and then the transmission burned up a few miles later. It seems there was a cut line to the transmission cooler, and it quickly went dry. I missed the leak because of all the power steering mess, and thought the power loss was a faulty cruise control. This doesn’t help you, but maybe I took one for the team and your transmission problem isn’t too bad.

Transmission temp of 210 deg should be ok. Max is 240 – 250 for non synthetic fluid. I think the 8V92 shuts down around 205. That is probably what happened.
How bad is the leak? Could you just refill the power steering and check transmission fluid and keep going slowly? Use low gear on inclines to keep RPM and coolant flow up.
You are almost on top of the Siskiyou pass, one more steep incline just before the OR border. Then it is all downhill to Medford.
How are your brakes? Jakes? There is a 6+ mile 6% grade coming down the pass.
Southern Oregon Diesel in Roseburg has a good reputation but it is a few miles beyond Medford and a couple of minor passes.

Southern Oregon Diesel does not work on buses anymore. They rented/ leased out the big shop. Now they focus on diesel pickups.

We had a bunch of tow companies afraid or unable to to it, but Star Towing brought us to Freightliner in Medford.
All in all, not a bad outcome. We’ll get some issues worked out and I’ll come back for it
