HUDY Engine Break-In Bench
The HUDY Engine Break-In Bench is the ultimate tool for
easy, safe, and professional break-in of your .12/.15/.21ci
engine (with 5mm extended crankshaft). It allows for a
controlled break-in process that reduces wear & tear
on engine components, ensuring increased performance,
reliability, and longevity.
Constructed of top-quality components of tough aluminium
and spring steel, the Engine Break-In Bench comes partially
assembled from the factory to get you running sooner.
The heavy-duty aluminum base plate with integrated
clamps provides quick, solid mounting on any workbench,
and a large protective shroud safely covers the spinning
propeller. Other features include a large-capacity 125cc
fuel tank, pre-assembled throttle linkage, universal engine
mounts, and special propeller.
Break in your engine like the pros!

EQUIPMENT REQUIRED FOR OPERATION
The HUDY Engine Break-In Bench
is designed for use with all
.12/.15/.21ci nitro engines with
a 5mm extended crankshaft. The
tapered crankshaft cone that
was included with the engine
must be used.
When breaking in your engine, we
strongly recommend using the
same fuel that you plan to run in
your engine after break-in.
Normally, you should always run
your engine with an air lter.
However, an air lter is not
used during the break-in
process on the HUDY Engine
Break-In Bench.
Use a compatible, high-quality
exhaust system when breaking
in your engine. Be sure to use
all gaskets, springs, and other
required mounting hardware.
A glowplug starter is required
to ignite the glowplug for
starting. We recommend
using a high-quality, battery-
operated glowplug starter from
a reputable manufacturer.
A glowplug wrench is required
for removing/installing the
engine glowplug. We recommend
using a high-quality glowplug
wrench such as the #107581
HUDY Wrench-Glowplug /
Clutchnut.
6
A high-quality screwdriver
is required for adjusting the
carburetor. We recommend
using high-quality tools such as
those offered by HUDY.
High-quality Allen wrenches
(2.0mm and 2.5mm) are
required for assembling and
adjusting the HUDY Engine
Break-In Bench. We recommend
using high-quality tools such as
those offered by HUDY.
A crankshaft or piston locking
tool is strongly recommended
for preventing the crankshaft
from turning while installing and
tightening the propeller and
spinner. We recommend using
a locking tool from a reputable
manufacturer.
A 17mm wrench is required for
tightening the spinner on the
crankshaft. We recommend
using tools from reputable
manufacturers.
An electric drill is required to
spin the crankshaft to start
the engine. We recommend
using tools from reputable
manufacturers.
A temperature gauge is
useful to check the engine
temperature during the break-in
period.
7
A hairdryer or heat gun is
recommended to pre-heat the
engine prior to initial starting.
Self-adhesive foil tape is
recommended to cover the
engine head ns to prevent
overcooling during break-in.
FACTORY PRE-ASSEMBLED
The HUDY Engine Break-in Bench is pre-assembled at the
factory with the exception of the fuel tank and stands,
which must be installed before use. Attach the two plastic
support stands to the base plate using the included
at-head screws, then attach the fuel tank to the stands
using the two button head screws and rubber grommets.
A pair of pliers is required to
connect the throttle control
rod ball-joint to the carburetor.
We recommend using a pair
of needle-nose pliers from a
reputable manufacturer.
