96.5.16 Dual Tachometer Indicator
NOTE
S/Ns 30576, 30687, 30931,
30817 and 30599 use an AC
powered Dual Tachometer
indicating system. For all S/Ns
except 30576, 30687, 30931,
30817 and 30599 refer to Section
96.6 for details of the DC
powered indicating systems.
The dual tachometer indicator system consists of
the engine power turbine tachometer generator,
rotor tachometer generator and dual tachometer
indicator.

Tachometer Indicator System (Rotor Rpm,
Power Turbine Rpm
SPECIAL TEST EQUIPMENT
TYPE OR MODEL NOMENCLATURE
Howell H337 Engine Test Set
or Equivalent
96.5.17.1 Disconnect
connector (P35) from
main rotor tachometer generator and connect to
matching receptacle on test set. Energize
tachometer generator on test set. Verify rotor
tachometer pointers on pilot and copilot dual
tachometer indicators read upscale and indicate
approximate speed at which test set tachometer
generator is turning.
96.5.17.2 Disconnect
connector (P35) from
test set and connect to rotor tachometer
generator.
96.5.17.3 Disconnect
connector (P111) from
engine power turbine tachometer generator and
connect to matching receptacle on test set.
Energize tachometer generator on test set.
Verify power turbine tachometer pointers on pilot
and copilot dual tachometer indicators read
upscale and indicate approximate speed at which
test set tachometer generator is turning.
96.5.17.4 Disconnect
connector (P111) from
test set and connect to power turbine tachometer
generator on engine.
96.5.18 Gas Producer Tachometer
Indicator
NOTE
S/Ns 30576, 30687, 30931,
30817 and 30599 use an AC
powered Gas Producer
Tachometer indicating system.
For all S/Ns except 30576,
30687, 30931, 30817 and 30599
refer to Section 96.6 for details of
the DC powered indicating
systems.
The gas producer tachometer generator on the
engine sends a frequency signal to the engine
gas producer tachometer indicator proportional to
engine gas producer speed. Gas producer speed
indication is given in percent of rpm.

Energize tachometer generator on test set.
Verify engine gas producer tachometer pointers
on pilot and copilot dual tachometer indicators
read upscale and indicate approximate speed at
which test set tachometer generator is turning.
96.5.19.2 Disconnect
connector (P89) from
test set and connect to engine gas producer
