Section 8
Electrical System and Components
Operation (Solenoid Shift Starters)
When power is applied to the starter the electric
solenoid moves the drive pinion out onto the drive
shaft and into mesh with the fl ywheel ring gear. When
the pinion reaches the end of the drive shaft it rotates
the fl ywheel and cranks the engine.
When the engine starts and the start switch is
released the starter solenoid is deactivated, the drive
lever moves back, and the drive pinion moves out of
mesh with the ring gear into the retracted position.
Starter Removal and Installation
Refer to the "Disassembly" and "Reassembly"
sections for starter removal and installation
procedures.
UTE Starter Disassembly
1. Remove clip.
2. Remove cap screws and solenoid. Scribe
alignment marks on caps and frame to aid
assembly.
3. Remove the thru bolts, drive end cap,
commutator end cap, and frame.
4. Remove drive lever.
5. Remove thrust washer and retainer to remove
drive pinion from shaft.
UTE Brush Replacement
Replacing brushes in the solenoid shift starters is
exactly the same procedure as explained for the UTE
starter in the previous subsection.
UTE Starter Service
Clean drive lever and armature shaft. Apply Kohler
electric starter drive lubricant (52 357 02-S) to lever
and shaft.
UTE Starter Reassembly
1. Slide frame over armature and place commutator
end cap in position. Hold in position temporarily
with tape.
NOTE: Be sure alignment marks on caps and
frame are in proper position.
2. Place drive pinion (with seal), thrust washer and
retainer on drive shaft.
3. Place lever in position on drive shaft.
4. Place solenoid plunger on drive lever and position
drive end cap over drive shaft (be sure the rubber
dust cover is in place at the drive lever).
5. Fasten the end caps with the thru bolts.
6. Place the spring in the solenoid and fasten
solenoid to drive end cap using hex. cap screws.
7. Replace the clip.
Nippendenso Solenoid Shift Starter
Some specifi cations call for the Nippendenso solenoid
shift starter. Operation of this starter is identical to
that previously discussed. There are, however, some
differences in servicing the unit. Refer to Figure 8-27
for exploded view of the starter.
Starter Disassembly
1. Disconnect the wire from the solenoid.
2. Remove the hex. nuts securing the solenoid, and
remove the solenoid from the starter assembly.
3. Remove the two thru bolts.
4. Remove the commutator end cap.
5. Remove the insulator and brush springs from the
brush spring holder.
6. Remove the armature from the frame.
7. Remove the drive lever and armature from the
drive end cap.
NOTE: When removing the lever and armature
be careful not to lose the thrust washer.
8. The stop collar consists of two similar pieces
held in place by being snapped over a retainer.
The retainer is held in place by a groove in the
armature shaft. To remove the stop collar the two
pieces must be pried off the retainer.
