Main Bearing Case Assembly (Z602-E4B, D902-E4B)

1. Remove the two main bearing case screws 1 (4), and remove

the main bearing case assembly 1 (1), being careful with

crankshaft bearing 3 (5) (9).

2. Remove the main bearing case assembly 2 (2) and the main

bearing case assembly (3) as above. Keep in mind, however,

that the thrust bearing (8) is installed in the main bearing case

assembly (3).

(When reassembling)

• Clean the oil passage in the main bearing cases.

• Apply clean engine oil to the bearings.

• Install the main bearing case assemblies in original positions.

Since diameters of main bearing cases vary, install them in

order of marking (b) (1 for Z602-E4B and 1, 2 for D902-E4B)

from the gear case side. (Refer to the figure.)

• Be careful not to confuse the top and bottom of the crankshaft

bearing 3 (5) (9). (Install the bearing with the oil groove (c) up.)

• Match the alignment numbers (a) on the main bearing case

assembly 1 (1).

• Do the same for the main bearing case assembly 2 (2) and the

main bearing case assembly (3) too.

• When installing the main bearing case 1 and 2, face the mark

"FLYWHEEL" to the flywheel.

• Install the thrust bearing (8) with its oil groove facing outward.

• Confirm that the main bearing case moves smoothly after

tightening the main bearing case screw 1 to the specified

torque.
