Kobelt Push-Pull control heads are designed with a removable dome for
easy installation.
General Information
In order to provide a satisfactory push-pull control system, the following
installation pointers must be considered:
• Install the control head on a flat and clean surface. An uneven
surface tends to deform the control head frame and causes binding
in the bearing sections.
• When attaching the cable to the control head or at the output end, it
is important not to twist the inner core of the control cable. This will
cause additional friction.
• It is not recommended to run cables in series since the Lost Motion
becomes too excessive to ensure good control.
• The cable connectors at each end must be positioned in such a
manner that the handles are synchronized and will take full travel in
either direction without exceeding the available cable travel.
• It is very important that all cable attaching screws are firmly
tightened. We recommend the use of “Loctite” or equal on the cable
attaching screws on installations subject to severe vibrations.
• Use a small amount of grease on the cable connecting pins in the
control head, and lubricate the bearing shaft and detent to improve
the life and free movement of the control head.
• On two lever clutch and throttle control it is recommended that the
stop screws in the control head be used to limit handle travel. This
will prevent overloading of the control cable since only the required
amount of travel can be used.
Dual Function, Single Lever Control Heads
Cable Installation
Initially, the cable shall be attached with the cable clamp to the
support bracket. Screws must be securely tightened.
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 last attaching point on the clutch actuating 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 access 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 the control head.
It is also very important that the clutch control valve goes from
neutral to both gear engage 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, 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 appropri-
ate connection point for the adaptor kit, on the throttle cam.
The clutch actuating pivot plate on the control head must com-
plete its cycle in either direction without bottoming the cable in the
pushing mode and without going beyond the maximum extended cable
travel available in the pulling mode.
One Function Control Heads
Cable Installation
1. Loosen flat head screws (Item 1) to separate pin retainer (Item 3)
from pivot plate (Item 2). Screws are provided with sufficient length
allowing to insert the pin (Item 5) without total screw removal.
2. Install jam nut and cable connector (Item 4) onto end of cable.
3. Now slide pin into cable connector; place between pivot plate and pin
retainer and tighten flat head screws (Item 1) securely.
Note: For installations subject to severe vibrations, use “Loctite” or
equal when tightening the flat head screws (Item 1).
