1995-96 STARTING & CHARGING SYSTEMS Volkswagen Starters Cabrio, Golf III, GTI, Jetta III DESCRIPTION Starter is a brush type, series-wound electric motor with an overrunning clutch. Field frame is enclosed by commutator end frame and drive bushing, and carries pole shoes and field coils. A splined armature shaft drive end carries drive assembly. TROUBLE SHOOTING NOTE: ON-VEHICLE TESTING STARTER DOES NOT CRANK ENGINE 1) Ensure battery is fully charged. Ensure electrical and ground connections are clean and tight. With ignition switch in START position, measure voltage at spade terminal of starter solenoid. Reading should be at least 8 volts. If voltage is as specified, go to step 3). If voltage is not as specified, go to next step. 2) Measure voltage at ignition switch. If reading is at least 8 volts, check wiring between ignition switch and starter solenoid. If voltage is not as specified, replace ignition switch. 3) While operating starter, measure voltage at field (starter) terminal of starter solenoid. If reading is at least 8 volts, repair or replace starter. If reading is less than 8 volts, replace starter solenoid. NOTE: See TROUBLE SHOOTING article in GENERAL INFORMATION. On vehicles with automatic transmission, also check park/neutral switch. STARTER CRANKS TOO SLOWLY TO START ENGINE Ensure battery is fully charged. Ensure electrical and ground connections are clean and tight. If necessary, clean and tighten ground strap between transmission and body. DO NOT loosen ground strap on body. If starter still turns slowly, repair or replace starter. REMOVAL & INSTALLATION Removal & Installation 1) Disconnect negative battery cable. Support engine/transmission assembly with Support Beam (VW 10-222A) and Leg

Removal 1. Disconnect negative battery cable. 2. Remove the upper two bolts from the intake manifold bracket. 3. Raise vehicle and support. 4. 5. 6. 7. 8. Remove the two bolts on the clutch release cylinder and push aside (M/T). Remove the lower two intake manifold bracket bolts. Remove intake manifold bracket. Remove the two upper starter bolts. Remove the lower starter bolt. 9. 10. 11. 12. Pull the starter from the clutch (M/T) / torque converter (A/T) housing and prop in place. Lower the vehicle. From above, disconnect the S-terminal connector. Remove nut and lock washer on B-terminal. 13. 14. 15. 16. Disconnect B-terminal. Raise and support vehicle. Push transmission wire harness aside. Remove starter. Installation 1. Place starter in engine well. 2. Lower vehicle. 3. Connect B-terminal wire. 4. Install washer and nut on B-terminal and tighten. 5. Connect S-terminal. 6. 7. 8. 9. 10.

If the transmission jumps out of gear during deceleration, inspect the components that may allow for the gears or shafts to tip. If the gears or shafts tip, the synchronizer sleeve can disengage from the selector teeth on the speed gear. If the transmission jumps out of gear during acceleration, inspect the components that may not allow full engagement of the synchronizer sleeve to the selector teeth on the speed gear. Insufficient engagement of the selector teeth under torque may cause the transmission to jump out of gear. Test Description The numbers below refer to the step numbers on the diagnostic table. 2. A static shift test is performed by shifting into all gear positions with the engine not operating. While performing the test, slowly move the shift lever. Feel for proper movement of the shift lever and transmission internal shift components. 4. A dynamic shift test is performed by shifting into all gear positions with the engine operating. Test for the correct mesh of the synchronizers sleeve and the speed gear selector teeth. Move the shift lever, and feel for the synchronizer sleeve to release from the gear, then let up on the clutch pedal. Depress the clutch pedal and move the shift lever to engage the gear again, to ensure full travel of the shift components. 5. This step inspects for worn or damaged transmission or engine mounts. Loose mounts may cause a shock on the transmission allowing for gear disengagement. 6. This step inspects for the misalignment of the torque tube to transmission. Misalignment may put a bind on the input shaft, allowing for the input shaft or the mainshaft to tip. 8. This step inspects the pilot bearing and the pilot bearing journal on the input shaft. A worn pilot bearing or input shaft may allow the input shaft to tip, causing gear disengagement.
