ENFIELD Drive legs (or Z-Drives/Sterndrives) are
very popular on the River, being easily lifted to clear or change
the propeller or for mooring in shallow water.
Enfield model 130 Z Drives may be used with engines
producing up to 140 lbsft (19 Kgm) maximum torque. For petrol
engines this is equal to approximately 130 HP. When diesel
engines are used, the horse power may be 70-80 HP depending on
the make and type of engine.
The Enfield
Z Drive can only be used with engines which rotate anti-clockwise
when viewed from aft.
Close or distance coupled to any inboard engine, the drive can
take a propeller up to 14" (355mm) diameter through reduction of
1.65:1. Propeller rotation is standard left hand; right hand is
available for use with counter rotating twin installations.
Swivel and non-swivel versions are available.
Key
Benefits
Swivel unit weighs only 104 lbs (47Kgs), and is ready to bolt
direct to your transom. Inboard cranking means that the swivel
model can lift athwartships for easy parking and maintenance, and
lift 55° rearward to help avoid underwater obstructions.
The non-swivelling model embodies all the features of the swivel
model with the exception of the athwartships parking mode, but
has the advantage of a price and weight reduction to 90lbs (41
Kgs), and a greater lifting angle of 70°.
DIY users will find fitting simple and straightforward.
Accessories
We supply a standard coupling kit from the engine flywheel to the
Z Drive, morse cable kits, propeller and nose cone kit. We supply
a rudder which can be clamped to the Enfield Z Drive.
It is essential that these units are regularly serviced,
correctly set up and oil level maintained. Serious and expensive
damage can be caused by neglecting regular service. Any leaks
from the several oil seals will allow water to enter and oil to
seep out. This will cause corrosion of the internal parts,
premature failure of bearings and gears and possible total
seizure.
Even the simple task of replacing a gear shift cable requires
exact setting up for correct performance.
We carry a
full range of spares, seals, gaskets and all commonly required
service parts. Any items we do not have in stock can be obtained
overnight if necessary.
Several items have been modified over the years and we will be
happy to advise on your particular unit.
We are experts at servicing Enfield Drives, have a selection of
special tools and the experience to strip and re-build your unit
to the latest specifications. The picture above shows a unit just
lifted from the water.
Below we shall be showing pictures of the new modifications,
some examples of severe damage and a finished unit.
The new
oilseal housing for the lower unit now has the capacity
to take two back to back oil seals, providing a positive seal
for both the internal oil and the external water pressure.
Well worth changing this part when the lower unit is stripped. It
is a simple replacement.
This picture shows the
original gear shift rod and fork on the left with the new
modifications on the right.
As you can see the original shift rod is simply a bent rod prone
to distortion whereas the modification is a complete circle which
cannot deform.
The fork which actuates the gearshift has also been modified from
simple pressed steel to a much more robust bronze casting.
These parts require considerable work to replace involving
removal of the gear change bearing, stripping the lower unit and
removal and replacement of the prop. shaft ball bearing race.
Once fitted there should be a positive improvement in gear
engagement.
The roller
bearings which support the various shafts and bevel gears
have been upgraded to vastly increase the bearing surface. The
new bearings fit in place of the originals but have more than
twice the working surface area. Any units required to run under
high load conditions should always be modified with these units.
It does however require a complete stripdown of the upper and
lower housing.
