Assembly

S5JB0B1A06010

Disassembly

1) Loosen screw (3) and then remove bearing retainer

(1) from drive end frame (2).

2) Push out drive end bearing by using hydraulic press

(1) and special tools.

Special tool
(A): 09913–75821

Assembly

1) Press-fit drive end bearing by using special tools and

press (1).

Special tool
(A): 09913–76010

CAUTION

!

Be sure to use new bearing.

2) Install bearing retainer to drive end frame and tighten

screw.

Generator Inspection

S5JB0B1A06005

Rotor

1) Using an ohmmeter, check for continuity between

slip rings of rotor. If there is no continuity, replace the
rotor assembly.

2) Using an ohmmeter, check that there is no continuity

between slip ring and rotor. If there is continuity,
replace the rotor assembly.

3) Check slip rings for roughness or scoring. If rough or

scored, replace the rotor assembly.

Stator

1) Check resistance between the following leads of

stator. If there is no continuity, replace coil assembly.

Stator lead resistance

2) Using an ohmmeter, check that there is no continuity

between coil leads and stator core. If there is
continuity, replace coil assembly.

Brush and Brush Holder
Check each brush for wear by measuring its length (a)
as shown. If the brush is found worn down, replace the
brush.

Rectifier

1) Check continuity of rectifier by using an ohm meter.
2) Reverse the polarity of the tester probes and repeat

Step 1).

3) Check that one shows continuity and the other

shows no continuity.
If there is continuity, replace coil assembly.

Bearing
• Check that drive and bearing is not rough or worn.

• Check that end housing bearing is not rough or worn.
