Installation instructions for 2090 Series
When installing the control heads, it is important that they are located on a clean,flat surface which is easily accessible. The cables leading from
the main control head to the reverse reduction gear and the propulsion engine throttle should be installed and made functional first. It is important
that the following points are carefully observed.
As illustrated in the drawing in Position A (showing the clutch actuating pivot plate in the gear engaged position and the control handle in the
full speed position) the cable must pass slightly beyond the attaching point on the clutch actuating pivot plate in the pull mode. The cable must also
go slightly beyond position B in the push mode with the control head in a full speed position.
In order to obtain equal excess travel in both positions on the cable, the adaptor kit cable-end must be adjusted accordingly. After the proper
position is found, the cable-end is attached to the clutch actuating pivot plate. The locking nut must be secured. This will ensure that no mechani-
cal binding takes place in the cable or the control head. It is also very important that the clutch control valve goes from neutral to both gear engaged
positions without bottoming. A slight amount of end play is essential.
The throttle cable attached to the throttle actuating cam must also operate within the available stroke of the cable and the adaptor kit cable-end
must be adjusted in such a manner to avoid bottoming of the control cable in either direction. In order to obtain full handle travel in the speed range
it is important to select the appropriate connection point to the adaptor kit on the throttle cam.
After the master station is connected to the engine the cables can be connected from this station to the remote station. It is important that the
cables are the right length. Too short a cable can result in tight bends which will increase friction. Too long a cable will also result in extra loops
which again generate additional friction. Either of the above can make this control stiff and difficult to operate.
After the cable is attached with the clamps on the bottom of the supports of the control heads, the chain can be placed over the sprocket. When
the control head is in the neutral position (handle in mid-position), the loose ends of the chain should be equally long on either side of the sprocket.
The cable core is equipped with two nuts on either end. One of the nuts must be removed and the cable-end passed through the adaptor link. The nut
can now be reinstalled.
It is also important to remember that the cable must be crossed between the control heads in order to get the handles to move in the same
direction (the forward cable from the master station is attached on the aft side of the remote station and the forward cable of the remote station is
attached to the aft side of the master station). The cables have enough thread at the end to allow balancing of the handles at both stations. This
is best accomplished by placing the master station in the neutral position (handle straight up). The adjusting nuts at the end of the cable can now
be tightened or loosened as required to balance the handles. Over-tightening of the cable core will result in excessive friction and will make the
control system very stiff and difficult to operate. A deflection of 3/8”–1/2” in the cable to either side between the sprocket and cable conduit clamp
is essential. It is important that the two nuts and the cable-end are secured tightly against the adapting link. Two wrenches (3/8”) must be used to
accomplish this task. Under no circumstances must the chain be twisted when tightening these nuts.
Use only Felsted pull-pull cables to interconnect head and Felsted 40 series push-pull cables from control to gearbox/engine.
It is extremely important that all screws and nuts be securely tightened before the boat is placed into operation.
