CYLINDER INSTALLATION
Proper cylinder installation is the key to the successful operation of the
hydraulic steering system. An incorrectly installed cylinder is subject to rapid
seal and bearing wear and non-repairable damage.
An imaginary line drawn through the tiller arm hole at both hard over
positions will create the cylinder centre line. With tiller arm at hard over
positions, angle X and Y should be the same. Select the diagram and dimensional
data that corresponds with your cylinder model.
Notice
Not all possible cylinder mounting configurations
are shown, however, all necessary dimensions are shown regardless of mounting
configurations.…………………………………………………………………………………………………………………………….
CAPILANO HELM PUMPS
1250V, 1275V & 1350
A unique variable displacement feature on the 1250V and 1275V helms allows
the helms-person to adjust the amount of steering wheel turns to their
preference within a predetermined range. The 1350 helm is a fixed displacement
pump.
