Maintaining Hydraulic Steering: The Basics

24 May, 2010- Hydraulic steering wheel is a must for a high performance boat. Cable steering or partially hydraulic cable assisted steering do not match up to the rapid speed and razor sharp performance of full hydraulic steering. The only hassle with full hydraulic systems is the moving parts which call for regular checks. Here are few basics which needs to be followed while going through the routine check up of a full hydraulic steering

It is sensible to check the system from an external view point so as to be sure that the hoses are crack free and pliable. Look out for any wear and tear signs or abrasion of hoses too. Dry or worn out hoses tend to damage the system in twin way. One, by leaking and two, by letting the seawater seep into the system. This external monitoring also includes the examination of entire tie-bar assembly, nuts, bolts etc. Any kind of potential trouble regarding the cylinder can be traced when the boat is on the trailer. Air within the system can be detected by shaking the drive unit. An air less cylinder would never make any kinds of movement on shaking, but in case some movement is registered on shaking, it undoubtedly means that some air has been bled from the system. Also, it is necessary to check the seals and O-rings for cracks or breakage.

The inside of the boat has to be checked thoroughly for the steering fluid level and air presence. It is only necessary for the fluid level to remain constant from cold engine start till warm engine turn off. The dropping of fluid level during a cold start depicts the presence of air in the system and hence it needs to be bled off. A dark, thick and sludgy fluid also calls for replacement.

Keep a track of the power steering pump belts for appropriate tension, cracks etc.

Replacement of filters is another task which needs to be a part of the routine check. Most of the filters call for replacement after every 100 operating hours.
