The Serpent 733 is a complete new
platform for the 200mm categor y of
racing. It’s the next phase of evolution
of Serpent’s hugely-successful 200mm
chassis lineage, combining ultimate
performance into a single package.
The Serpent 733 is designed to be a
world champion, while still being easy to
use, assemble, and set up. You are now
part of the worldwide network of Serpent
drivers, which gives you superior technical
support and access to many benefits that
only Serpent drivers can enjoy.
The Serpent 733 offers state of the
art specifications and leads the way in
200mm chassis design, using all the
knowledge we have from 1/8 scale racing
into this design too. Continuously pushing
the performance envelope, Serpent ’s
engineers have added many new and
innovative features that can help take
your Serpent 733 into the winner’s circle:
new geometry, roll-centers and weight
balance, combined with new open and
very accessible design. A complete new
platform.
INSTRUCTIONS
Serpent’s long tradition of excellence
extends to their instruction manuals, and
this instruction manual is no exception. The
easy-to-follow layout is richly illustrated
with 3D-rendered full-color images to
make your building experience quick and
easy. Following the instructions will result
in a well-built, high-performance racecar
that will soon be able to unleash its full
potential at the racetrack.
This instruction manual has been divided
into sections that will logically lead you
through the assembly process of your
Serpent 733. Follow the assembly steps
in the order presented to ensure that no
problems occur during assembly. Each
step indicates all the fasteners and small
parts used. Bag numbers identify the
kit bag(s) that contains the appropriate
parts.
EXPLODED VIEWS AND PARTS LIST
The exploded views and parts lists for the
Serpent 733 are included in the back of
this manual. The exploded views show
all the parts of a particular assembly step
along with the Serpent part number. The
parts lists indicate the part number and
name of each part for easy reference
when ordering.

Pull the clutchbell away from the clutch shoe, and then
measure the distance B as indicated.
The clutch gap is A – B; the correct gap is 0.7mm.
If the clutch gap is greater than 0.7mm, you can easily
calculate the thickness of shims required to set the
correct gap:
Thickness of shims required (in mm) = A – B – 0.7
For example, using the values A=1.3mm, B=0.3mm
Shim thickness = 1.3 – 0.3 – 0.7 = 0.3mm
Place shims between the outer thrustbearing plate and
the rim of the thrustbearing carrier as shown.
