FOR FLYWHEEL REASSEMBLY (INSTALLATION).
1. Inspect brake pad to be free of dirt, oil or grease. If
pad is contaminated, or less than .060'’ at the
narrowest point, replace. See flywheel brake section
for procedure.
2. Compress brake lever
3. Install flywheel key
4. Install flywheel
5. Install the fan onto the flywheel so the Tecumseh
logo on the fan is on the magnet side of the flywheel.
6. Place starter cup into position and torque flywheel
nut to specification. Use a strap wrench to hold the
flywheel.
2. Use of a recoil starter (top or side mounted) with
the rope handle on the engine as opposed to within
24 inches of the operator position. This method is
acceptable if the mower deck passes the 360
degree foot probe test. A specified foot probe must
not contact the blade when applied completely
around the entire blade housing. This alternative
can be used with engine mounted brake systems
and typical bail controls. The blade stops within three
seconds after the operator lets go of the blade
control bail at the operator position and the engine
is stopped.
Tecumseh’s Flywheel Brake System provides consumer
safety by shutting down the engine and lawnmower
blade within seconds after the operator releases an
Engine/Blade control at the handle of the lawnmower.
The Brake Starter Mechanism may be used with either
of two options for starting:
1. Manual Rope Start
2. 12 Volt Starter System
Each system requires the operator to start unit behind
mower handle in operator zone area. The electric start
system also provides a charging system for battery
recharge when engine is running.
NOTE: Electric start systems equipped with a charging
system WILL NOT RECHARGE a dead battery. This
system is designed to maintain the charge. Before
storage and again in spring the battery should be
charged with the O.E.M. supplied charger.
BRAKE SYSTEM
Tecumseh’s brake system provides a method of meeting
compliance standards which became law as of June
30, 1982. There are two additional methods used by
equipment manufacturers that also meet compliance
standards and they are as follows:
1. B.B.C. Blade Brake Clutch: This system is
designed to stop the blade from rotating, in
compliance with the 3 second stopping regulation,
after operator lets go of the safety bail. This system
allows the engine to continue running while stopping
the blade. B.B.C. systems are installed by various
O.E.M.'s all parts are supplied by them.
STOPPING THE ENGINE. In the stop position the brake
pad is applied to the inside edge of the flywheel; at the
same time the ignition system is grounded out.
