  3. Position retainer and thrust washer with snap ring in between. Using 2 pair of pliers, grip retainer and thrust washer and squeeze until snap ring is forced into retainer and is held securely in armature shaft groove.
  4. Lubricate drive gear housing bushing. Engage shift lever yoke with clutch and slide complete assembly into drive gear housing. On gasoline models, the shift lever may be installed in gear housing first. Install the shift lever pivot bolt. Tighten bolt and install solenoid assembly on drive gear housing.
  5. Apply Sealer (1050026 or equivalent) to solenoid flange where field frame contacts it. Position field frame against drive gear housing on alignment pin, being careful not to damage brushes. Lubricate commutator end frame bushing with Lubricant (1960954 or equivalent).
  6. Install washer on armature shaft and slide end frame onto shaft. On diesel starters, install insulator and then end frame onto shaft. Install through bolts and tighten.
