Flush & Fill Cart SFFC-70/2 | 9
The Stinar Flush and Fill Cart, Model SFFC-70/2 is a towable service unit
designed for draining contaminated air vehicle coolant for storage in the
cart and eventual disposal. Heated, filtered and deaerated clean coolant is
then pumped from the service cart into the air vehicle in three modes. There
is a flush mode that eliminates residual contaminated coolant. There is a
fill mode that supplies the aircraft with fresh coolant. The deaerate feature
removes all the gases in the system from the coolant. The flush and fill
cart consists of a coolant tank, waste tank and coolant-dispensing system
mounted on a two-axle trailer. The coolant dispensing system consists of a
electric motor-driven diaphragm pump that supplies coolant through a fill
hose. A bleed hose is also used on the cart.
1.1.1 | Equipment Systems and
Components
The major operating systems and components of the flush and fill cart are
described in the paragraphs below. See Figure 1.1.1 for locations.
1.1.1.1 | Cart Chassis
The flush and fill cart chassis provides a mobile platform for the coolant
tank, coolant-dispensing system and electrical system components. The
chassis consists of a rectangular steel frame with a fixed rear axle and a
pivoting front axle assembly. The front axle assembly includes a tow bar
and front wheel brakes engaged by raising and locking the tow bar in an
upright position. The cart is equipped with four 4:80 x 4:00 x 8 tires.
1.1.1.2 | Coolant System
The coolant-dispensing system is used to pump contaminated coolant
from the aircraft. See Figure 1.1.1.2 for coolant system schematic. The fol-
lowing paragraphs describe the major system components:
Coolant Tank
The coolant tank is bolted to the cart frame. The tank is constructed from
type 304 stainless steel. Internal safety baffles prevent sloshing and dis
-
tribute load forces. The coolant tank has the following features:
