Title: Squeaky steering.
Post by: CountingFireflies on September 08, 2011, 06:47:53 PM
So at some point in Georgia, I pulled out the maintenance manual and started looking at all the orifices that needed lubing and greasing.  I read through the chapter on power steering and discovered the location of the sight glass and fill tube.  What I discovered was also that it was low.  And I said to myself, "the first gas station we pass, fill up the P/S fluid!".  So we shoved off from red top mountain state park and as soon as I hit the highway, that ominous P/S growl started.  I filled up the reservoir, but was obviously too late.
Fast forward 1100 miles, and I'm in rural Vermont with no reasonable expectations of getting the system bled.   So finally the question:  am I doing any damage to the system by running it with bubbles?

You might check into the type of fluid. Mine takes 30 weight oil. They say you need to jack front up and steer back and forth to get air out I didn't do this and mine still working fine.

Try to let it sit overnight then with the front end off the ground cycle the steering back and forth with the engine running. That is the procedure for my Sheppard system which takes 10w-40. If that doesn't work check your pump. They can get noisy when they get tired. At least mine did.

I got off on the line above in my book the steering takes 10 weight in mine not 30 weight. I have serviced it with 10w-30 after I did repairs to fix leaks. Sorry for misinformation.

Most of the steering gears have a air bleeder some are just a bolt in the gear,they also make a orifice to stop the whining I posted the number here a few days ago  

good luck

So it sounds like I'm not doing any permanent damage except for the park rangers hearing.  I have been keeping the fluid level topped off with over the counter p/s fluid, and I checked the manual and it suggests 30w.   I'm in central Vermont helping with town repairs and I've got a note in to the local fire chief to see where a diesel shop is so I can get the front end lifted up.

Thanks all for the input.

The part number Clifford is talking about is: 3331991k
The only problem is I don't know what website you get that part from??
Also I have an MCI 102C3 and I have only been using power steering fluid - should I be using something different??

Many of the instructions I have read for bleeding the steering call for raising the wheels and turning in both directions BUT DON'T HIT THE STOPS.  I don't know why but I have seen it emphasized more than once.
