Yellow values are entered by user.

Green values are calculated 

Simply enter the required values (the one's with the yellow labels) and the calculator will automatically update.

Step 1 - Calculate Approximate Kingpin Tourque (in/lbs) Weight on Steered Axle (lbs)
Coefficient of Friction
Nominal Tire Width (in)
Kingpin Offset at Ground Intersection (in)
DriveFactor (2 = steered wheels driven, 3 = locked)
Kingpin Tourque (in/lbs)
Step 2 - Calculate Approximate cylinder force Minimum Radius Arm (in)
Cylinder Force (lbs)
Step 3 - Determine pressure rating of system Pressure rating of pump (psi)
Step 4 - Calculate required Cylinder Area (sq. in) Cylinder Area (sq. in)
Step 5 - Determine type of cylinder used Style
(1 = single balanced)
(2 = single unbalanced)
(3=cross connected unbalanced)
Step 6 - Determine diameter of shaft (rod) of cylinder(s) Shaft diameter (in)
Step 7 - Determine required cylinder stroke (in) Cylinder Stroke (in)
Step 8 - Calculate approximate required cylinder bore (in) Cylinder Bore (in)
Step 9 - Calculate swept Volume of Cylinder(s) (cu. in) Bore diameter (in)
Swept Volume (Cu. in.)
Step 10 - Calculate required steering unit Number of turns lock to lock
