Hydraulic Linear Drive - Installation Guide

2. Attach the rod end to the tiller pin:
•
place the rod end onto the tiller pin
•
secure with the supplied washer and R-clip (see Figure 7)
Steering check
When you have mounted the ram, turn the boat’s steering wheel from
hardover to hardover and check that:
•
Angular movement of the ball end fitting is less than 5 degrees
(see Figure 5). If you exceed this 5 degree limit, the drive will
catch on the tiller arm/rudder quadrant and the ball joint will bind.
•
No part of the drive unit fouls the boat’s structure when the push
rod moves in and out.
•
The total rudder movement is limited to +/- 35 degrees by the
steering system end stops rather than the linear drive’s end limits
(see Figure 8).
Figure 8: Total rudder movement
CAUTION:
Make sure rudder movement is limited by the steering system
end stops before the push rod reaches its end stop. Failure to do
this could damage the drive and will invalidate the warranty.
Installing the other parts of the system
Note: To make installation easier, we supply the hydraulic linear
drive system pre-plumbed, pre-filled with hydraulic fluid and
pre-bled, with just the reservoir empty. As a result you should not
need to bleed the system during installation. If you do need to
disconnect the pipes for any reason, contact Raymarine Technical
Services Call Center for advice on bleeding the system.
