RACK AND PINION STEERERS id RACK AND PINION STEERERS
Designed specifically for double ended boats up to about 38'
with transom hung rudders. Edson's new model Rack and Pinion
Steerer operates in a similar fashion to the standard Rack and
Pinion Steerer with the feel of a tiller and very responsive to the
touch. It is available in two models: for straight in-line installations
on vertical or nearly verticle rudders and for offset installations, re-
quiring a shaft universal and an adjustable bearing for angled rud-
ders. They require only a small slot in the stern for the operating
rod. This slot can be easily sealed with a homemade boot similar to
one for a mast step.
Fig.814 Double Ender Rack and Pinion Steerer consists of a Rack
and Pinion Steerer with lever, 2 clevis units, connecting rod and-a
rudder lever unit. The geared quadrant is designed to mount on a
1-112"13.8cm dummy rudderpost. The ''A" dimension is 21 ", theUC"
dimension is 16" or either is available to suit. Weight 46 lbs.120.7k.
Fig. 815 Double Ender Rack and Pinion Steerer complete with shaft
universal and 1" self-aligning bearing. This steerer is the same
basic model as the Fig 814, but it incorporates a shaft universal and
bearina. This Divots at a ~oint 14-112"forward of the dummv rudderpost.
The self'aligning bearing is then placed forward of tie universal
as close to the wheel as possible to keep the wheel with a solid
feel. The universal can change the shaft angle up to 30 degrees.
Weight 49 lbs.122.lk.
Fig. 613 Outboard Lever Quadrant Assembly consists of a
12"/30.5cm quadrant (Fig. 668) 2 clevis units, connecting rod, and
rudder lever unit. This assembly is designed for double ended
boats which want to use a roller chain type steerer (ie Pedestal,
Bulkhead Steerer, or Geared Reduction Steerer) in conjunctionwith
an outboard rudder quadrant. The steering cables can be ledj #)
aft from your choice of steerers using an appropriate combination -'.
of sheaves or ~ull-~ull conduit. The quadrant is desianed to mount
on a 1 112" 13.8cm dummy rudderpost. For ordering &d installation
instructions, refer to the double ended rack & pinion steerer below.
INSTALLATION INFORMATION
First of all it is important to establish and install the reinforced plat-
form that the dummy rudderpost is going to be bolted to. Bear in
mind that this surface must be of sufficient strength as it must
absorb all of the steering loads. This platform must be 90" to the
rudder on a plane where you wish to install the rudder lever. Also
note that the geared rack and pinion quadrant requires a minimum
of 10" on each side of the dummy rudderpost to swing in. This
dimension will help in establishing the "C" dimensions.
Temporarily mount the dummy rudderpost and assemble the
rack and pinion gear and housing. Assemble the clevis, the connec-
ting rod, and the rudder lever unit. With 'C' clamps, attach the
rudder lever unit to the rudder. Now operate the steerer noting the
rudder travel from side to side. The location of the lever on the rud-
der, either fore or aft or possibly even shimmed to starboard, deter-
mines equal travel from side to side. Take time with the positioning
of this lever and be precise. When you are satisfied, secure all parts
and install stops, such as wooden blocks on each side of steerer to
limit its travel to the desired arc. Provisions for an emergency tiller
should now be made if you do not already have one.
ORDERING INFORMATION
-
When ordering a Rack and Pinion Steerer for a double ender,
please specify the figure number, 'A' & 'C' dimensions, type o
boat, and a description of the location of the dummy rudderposj3,
with dimensions. Unless otherwise specified, the geared quadrant '"
will be bored with a 1-112" dummy rudderpost. Refer to ordering information
for Rack and Pinion Steerers for more detailed considerations
when determining the 'A' dimension. Individual parts
are available, see Fig 616, 808 and 836, Tiller Arms. If you require
further assistance, please do not hesitate to contact the Edson factory
for more information.
The Rack Aft steerers are for those boats with at least 12 inches
of space aft of the rudderpost and limited space forward. The basic
dimension of the gear should be carefully noted as it is important to
place the wheel about 32 inches up from the cockpit sole to allow
the helmsman to steer comfortably.
Fig 343 Aft Mount Rack and Pinion Steerer - size 1 is for use on aft
racked rudderposts 1" to 2-118" diameter with a maximum key of
318" in on the aft side of the rudderpost. If the bore is not specified
the rack will be furnished with a718" pilot hole. The "A" Dimension
on the wheel shaft is standard at 15 inches or is available to suit.

Q vertical rudderposts or severly aft raked rudderposts. This steerer
comes with ashaft universal and two 1 "self aligning bearings.This

The New Fig 345 Aft Mount Rack and Pinion Steerers are for use on ~xtenderj(
boats with rudderposts raking forward. Although similar to Fig.
344 in function, the exact location of the shaft universal allows
adjustment of the steering wheel from a position parallel to the
plane of the rudderpost to a more comfortable vertical or aft rake
position.
