Flexible Coupling - TM-5-4320-258-120073

c. Installation.

(1) Install the coupling (para 4-48c).

(2) If the same pump is being installed as was removed, use shims (14 and 15) having thicknesses the same

as were removed. If a different pump is being installed, provide shim thicknesses which will aline the bearing housing

with the flywheel housing of the engine. Slide the pump into engagement with the engine so that the coupling halves are

properly alined.

(3) Secure the bearing housing of the pump to the flywheel housing of the engine with nuts (11, fig. P39).

Secure the pump feet to the skid with cap screws (8), nuts (9), and lock washers (10), making sure the shims (14 and 15)

are in place.

(4) Install the air eliminator valve and related parts (items 1 through 5, fig. 4-39).

(5) Turn over the engine and pump with the engine crank to make sure there is no binding ' between the pump

and engine before restoring the pump assembly to service.
