and its bore are not scored. Replace damaged parts with new ones.
(4) Check tube assemblies carefully for dents or crimps which might restrict the flow of oil. Replace damaged
tube assemblies, if necessary.
d. Oil Pump Reassembly (fig. 100).
(1) Install the idler gear (20) on the idler shaft (18). Secure the pump gear (9) to the drive shaft (10) with the
woodruff key (19), and install the snap ring (8). Insert the assembled shaft and gear into the pump body,
meshing the pump gear with the idler gear.
(2) Attach the drive gear (14) to the drive shaft with the taper pin (15), supporting the hub of the drive gear firmly
while driving the pin into place.
(3) Position the pump cover on the pump body by means of the locating dowel pins (5) and install the four hex
head bolts (1) and lockwashers (2). Insert the spring (26) and plunger (25) into the pressure relief opening
in the pump cover (7) and screw the reducing bushing (24) into place.
e. Installation (fig. 100).
(1) Lift the assembled oil pump carefully up into the upper oil pan, meshing the pump drive gear with the
crankshaft gear and alining the pump body mounting holes with the tapped holes in the mounting boss.
Install the two hex head bolts (11) and lockwashers (12).
(2) Screw a connector (16) into the pump body and the tapped crankcase oil passage, and install the tube
assembly (17) between the two connectors.
(3) Screw the connector (21) into the reducing bushing (24) and the elbow (23). Install the tube assembly (22)
between the elbow and connector.
(4) Apply a thin coat of shellac to the gasket surfaces of the pump and the suction line connection (4) and
position the gasket (6) on the connection. Loosely attach the bracket arms of the suction line connection to
the mounting boss within the upper oil pan with two hex head bolts (1), lockwashers (2) and plain washers
(3). Shift the connection toward the pump until the connection flange bears against the pump cover flange
and install and tighten two hex head bolts (1) and lockwashers (2). Then tighten the two hex head bolts that
attach the suction line bracket arms to the cast mounting boss.
(5) Install the oil intake screen (28) and cotter pin (27).
Install the lower oil pan (par. 217c) and fill the
lubricating system with oil (fig. 16).
