2015 Touring – MAIN DRIVE GEAR AND BEARING – CLEANING AND INSPECTION

1. Clean all parts in solvent except the transmission case and needle bearings. Dry with compressed air.

NOTE

Never wash the transmission case and needle bearings with solvent unless replacing the needle bearings. Normal cleaning methods will wash dirt or other contaminants into the bearing case (behind the needles) and will lead to bearing failure.

2. Inspect the main drive gear for pitting and wear. Replace if necessary.

3. Inspect the needle bearings inside the main drive gear.
Replace the needle bearings if the mainshaft race is pitted or grooved.

4. Replace the sprocket if teeth are cracked or worn. See 5.9 TRANSMISSION SPROCKET, Cleaning and Inspection for more information.

5. Inspect the needle bearings on the inside of the main drive gear. If mainshaft race surface appears pitted or grooved, replace these bearings.

NOTE

If replacing the main drive gear needle bearings and/or seal, continue as follows. Otherwise, proceed to 6.10 TRANSMISSION CASE, Assembly.
