The steering gear housing should be kept full of lubricant. Lubricate through the uppermost filler hole in top of steering
AVOID HIGH PRESSURE FILLING, TO PREVENT "BLOWOUT" OF SEALS. THE CAPACITIES
LISTED BELOW ARE BASED ON STANDARD GEAR MODELS FILLED WITH OIL-FLUID LUBRICANT
TO THE TOP OF FILLER HOLE WHEN THE GEAR IS MOUNTED AT A COLUMN ANGLE OF 350
WITH THE HORIZONTAL.
The Steering Gear capacity is 4.25 lbs.
Lubricate through the pipe plug filler hole or fitting in the top of the housing. Keep housing full by adding lubricant
periodically according to usage--every few thousand miles or at least spring and fall. Listed below are the recommended
1. Cam and Lever Steering Gears
A. S.A.E. 90 per Ross Specification 045165
B. S.A.E. 90 per Military Specification MIL-L-2105B
Grease per Ross Specification 045088
Military specification MIL-L-1032A for sub-zero operation (0°to -65°F).
Mobil fluid 300 for sub-zero operation(0° to -65°F).
2. Hydraulic Section
A. Automatic transmission fluid
1. Type "A" suffix "A"
2. Type "F"
The above oils should have an analine point between 175°-225° (test method ASTM Test No. D611). The analine point
affects the stability (swell or shrinkage of the oil resistance compound in oil seals).
The above lubricants and hydraulic oils are to be of a non-corrosive type, such that continued exposure to water vapor will
not have a detrimental corrosive effect on any steering or hydraulic motor components.
