System checks
Air in a steering system is the leading cause for faults. Air MUST be ruled
out in most cases to prevent costly replacement of good parts.
There are several ways to check for air remaining in the steering system.
Below are the quickest and easiest ways to determine if you have air in the
system. Long hose runs can affect the outcome of the following tests.
Engine push test
• Center engine.
• Using your hands, push engine back and fourth.
• While pushing, watch the steering cylinder body move.
Results
• If the cylinder body moves more than 1/4” you have air remaining in the
system and further bleeding is required.
Wheel turn test
• Note your helm pump and steering cylinder part number.
• Count your steering wheel(s) turns from hard-over to hard-over consult
the “quick reference turns” tables below.
Results
Wheel turns should be very close to the wheel turn chart numbers. If you
are well over these numbers, further bleeding is required.
If your wheel turns are at the correct number and the Engine push test
results in 1/4” or less cylinder body movement, contact technical support
at 604-248-3858 for further testing.
