hydraulic fluid through the use of a hand or air
motor-driven pump.
The A/M27T-5 Portable Hydraulic Power Supply
(fig. 1-8) is a single system hydraulic pumping unit
with a rated capacity of 20 gpm (gallons per minute) at
5,000 psi. It is a self- contained unit designed to check
performance and operating characteristics of aircraft
hydraulic systems. It is powered by a three-cylinder,
two-stroke-cycle diesel engine. The A/M27T-5 is
capable of delivering hydraulic fluid at controlled
pressures to operate aircraft hydraulic systems without
the necessity of starting the aircraft engine.
A/M27T-7 Portable Hydraulic Power Supply
The A/M27T-7 (fig. 1-9) is similar in operation to
the A/M27T-5 except for its source of power. The
A/M27T-7 is powered by a 50-hp electric motor. A
50-foot power cable is provided for connection to a
