Kobelt 2090 Series Installation Instructions

INSTALLATION INSTRUCTIONS FOR 2090 SERIES CONTROLS
When installing the control heads, it is important that they are located on a clean and 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 diagram below, 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 extend slightly beyond the attaching point on the clutch
actuating pivot plate in the pull mode. The cable must also retract 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 mechanical binding takes place in the cable or 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 pivot plate must also operate within the available stroke of the cable and,
again, 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 for
the adaptor kit on the throttle pivot plate.
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 of the correct 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 the
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 (with handle in mid-position), the loose ends of the chain
should be about the same length 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 then be re-installed.
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 should have enough
thread at the end to allow balancing of the handles at both stations in the neutral position. 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 at the cable-end
are secured tightly against the adapting link. Two 3/8" wrenches can be used to accomplish the task. Under no
circumstances must the chain be twisted when tightening these nuts.
Clutch and throttle cable connection kits are ordered by the control head number followed by -0901 for 30 series cable and -0902 for 40
series cable.
Two cables per engine are required for interconnecting the master and remote station. They are ordered as follows: 47-xx where xx is the
length in feet. Example 47-12 is a 12 ft interconnecting cable. Cables are available in even foot lengths from 8 to 30 feet long. Control
heads include all necessary parts to attach cables from the master station to the remote station.
