I just got my 1978 coach. I'm familiar with power steering on automobiles but not on a detroit (6V92TA). My guess is it is a larger version of the hydrolic power steering system. A reservoir, a pump and a gear box. My question is what type of fluid do I add to the reservoir? Also, does the pump supply any other hydrolic related devices? I can't think of any it would but always room to learn something so...
Location: Just North of Detroit, a surprizingly great city
According to the TRW/Ross website (I'm assuming you have the same Ross steering gear my 77 coach has) you can use Dexron, ATF E or A, Shell Rotella SAE 30, or most 10W30, 15-40 and 10W40 engine oils. Prior to overhauling my steering gear I had used Dexron but afterward I used Mobil 1 5W40 and it works just fine. Prior to the overhaul I tried some steering gear additives that basically were just thick oil and that seemed to improve my steering so that became the basis of my subsequent choice. While the Mobil 1 was not specifically approved I believed it would hold up better than dino oil
