How To Change Engine Control Cables on Your Edson Pedestal
- BUY YOUR REPLACEMENT CABLE:
Determine type and length of engine control cable using measurements
or markings from the original cable. Knowing the outside diameter
of the original cable jacket will help determine the cable type
and thread size. The length tip to tip of the cable core will give
you the proper length.
- REMOVE STEERING WHEEL
This will give you more room to work.
- REMOVE COMPASS
Before removing the compass bolts, run a piece of electrical tape
vertically from the compass across the engine control housing, top
plate, and onto the pedestal. Slit the tape at each joint. This
will help you realign the compass with the other parts when you
reassemble this upper part of the pedestal. Remove the four round
head 1/4-20 x 3-1/2 machine screws that serve as compass bolts.
- REMOVE THE BRASS CLEVIS PINS FROM THE CONTROL LEVERS IN THE
ENGINE CONTROL HOUSING
The clevises are screwed to the end of the engine control cables.
Note which holes in the control levers the clevis pins came from.
This helps when reassembling this unit.
- REMOVE ENGINE CONTROL HOUSING
- REMOVE THE CABLE HOLDER NUT OR ROUND HEAD MACHINE SCREW
located on the aft side of the pedestal tube approximately 7"
below the wheel shaft. This will release the Cable Holder (A-969
or A-705) that holds the two engine control cables. These cables
remain attached to the cable holder inside the pedestal tube.
- BRING BOTH CONTROL CABLES TO THE SAME SIDE OF WHEEL SHAFT.
From the top of the pedestal, push down both of the engine control
cables just far enough so you can bring the throttle control cable
(right hand side) under the wheel shaft and over to the left aft
side of the pedestal along with the clutch cable.
- PULL BOTH CONTROL CABLES UP.
With both control cables now on the same side of the steering wheel
shaft, pull the cables up until you can reach the cable holder.
- Due to the limited amount of space in the pedestal tube
the cable holder sometimes gets jammed up with the steering
chain and cables. One solution to this problem is to turn
the steering wheel shaft all the way to port, thus putting
most of the steering chain over on the left side with the
two engine control cables and cable holder. Then, while
pulling up on the engine control cables, turn the steering
wheel shaft back to starboard. The upward movement of the
chain can help bring the cable holder and control cables
up to a level where they can be reached.
- Working space can be gained in the upper section of the
pedestal by moving the chain forward of the chain sprocket.
To do this, first tighten the brake, then ease the tension
of the chain and steering cables by backing off the nuts
on the takeup eyes located on your radial drive wheel or
quadrant which is attached to the rudderpost. With slack
in the steering cables, lift the steering chain and move
it forward of the hub sprocket located on the steering wheel
shaft.
- REMOVE THE BROKEN ENGINE CONTROL CABLE
Now that you can reach the cable holder, remove the broken engine
control cable. When removing the bad engine control cable, make
sure you attach a "messenger" line, or the new replacement
cable, to the end of the original cable. You will use the "messenger"
line to run the new replacement cable through the same route as
the original engine control cable.
- RUN THE NEW ENGINE CONTROL CABLE
Using the "messenger" line, pull the new engine control
cable into place.
- REASSEMBLE BY REVERSING THE ABOVE PROCEDURES.
- Attach the new control cable to the cable holder.
- Push both control cables down into the pedestal far enough
so you can bring the throttle control cable under the steering
wheel shaft and over to the right hand side.
- Pull up and push aft on the engine control cables.
- Line up the cable holder with its screw hole on the aft side
of the pedestal. A long rod or screw drive will help. The A-969
Cable Holder has a threaded (1/4-20) stud that sticks out through
the hole. Use "Loctite" on thread. The A-705 Cable
Holder is held in place with a round head (1/4-20 thread) screw
that comes from the outside of the pedestal tube and screws
into the cable holder. Use "Loctite" on threads.
- Attach control cables to fittings on engine end.
- Put engine control housing in place.
- Attach clevises to engine control levers.
- Before mounting compass use the four 3-1/2" (Fig 817
Sz. 3.5) compass mounting bolts to hold the engine control housing
in place. Test and adjust the engine controls at this time.
-
Remove the four compass mounting bolts. Mount
the compass using, the original tape alignment marks, and
screw compass mounting bolts back in place using an anti-seize
compound on the threads.
