Special Front Mounting
When installing engine in a odd size frame it may be necessary
to modify the existing front mount. This is due to some oversized
down tube frames being longer or wider then the motor is
designed to fit.. If you find that the front engine mount will not
reach the down tube when the motor is mounted to rear tube you
will need to make modifications. You can use the extra mt. block
found in the tool kit to space the engine forward by cutting it to
fit and installed it at the rear. Another idea is shown in the
diagram at the right)
Figure 1.
You will need a 3/16" X 1"
flat steel bar 5 to 7 inches long. To determine
the length you will need attach the motor to the
rear (seat post) down tube. Measure underneath
the motor on the frame to makes sure there will
be enough room to mount the bar on the motor
and meet the front mount of the engine. The
length will also depend on the distance from the
frame to the motor.
Figure 2.
Drill three holes in the flat
bar. They will need to accept 6mm bolts
or 1/4 US thread depending on your
choice of bolt. For the left hole use the
furnished large down tube adapter to
determine placement of the hole. The
measurements for the two right wholes
are an estimate and may vary with
individual installations.
Figure 3.
Bend the bar as shown in
figure 3. The front, or left side must be
bent up high enough to connect to the
mounting holes on the front of the
engine. It is important that the two bar
ends are parallel to the frame not to each
other.
Figure 4.
Align the furnished large
tube adapter to the bar and mount to the
bottom of the bar. The bar will run
through the space for the frame on the
motor and the mounting holes will rest
on the adapter.
Figure 5.
Mark where the mount will
rest on the frame, be sure to line the
mount up with the frame so it is centered
and straight.. Remove the motor from the
frame. Drill two holes through the frame
using the finished mount as a guide. Bolt
the mount to the frame. On the bottom of
the frame use half moon caliper brake
mounting washers. Tighten the bolts
securely but do not over tighten or
damage to the frame may occur . Use
Lock-tite or similar product on the bolts
and buts along with lock
washers.
