INTRODUCTION:

This bulletin announces a change to the clutch system components optimizing their durability and resistance to certain severe driving  conditions including high-temperature operation.

 

PRODUCTION CHANGE INFORMATION:

The new clutch components were incorporated into production during mid-2018MY production starting with VIN J*806877.

 

PART INFORMATION:

The new clutch system components consist of the following:

Part Number / Description	Details / Notes
12342AA170  FLYWHEEL AY-FLEX ASSEMBLY	Facing diameter increased from 230 mm to 240 mm. Larger clutch cover bolt circle to accommodate larger facing and clutch disc. Yellow paint mark near crankshaft bolt circle for easy identification.
30210AA800    COVER COMPLETE-CLUTCH	Facing diameter increased from 230 mm to 240 mm. Larger clutch cover bolt circle to accommodate larger facing and clutch disc. Outside of cover stamped with #AA800 for identification purposes.

 

 

SERVICE PROCEDURE / INFORMATION:

Whenever clutch system repairs are necessary, follow the procedures in the applicable Service Manual.  There are no changes to the existing Service Manual procedures when installing these new components.

IMPORTANT NOTES:

• For multiple occurrences or low mileage clutch disc / cover / flywheel replacements due to excessive wear or failure, always confirm the customer’s driving habits or usage conditions before proceeding with any clutch system repairs.
• Using the new-style replacement parts listed above WILL NOT protect the clutch system from severe abuse.
• Should the customer’s driving habits cause excessive and / or premature wear of “old-style” components, replacing all 5 of the parts listed above as a set will improve durability of the clutch system.
• If the new-style pedal assembly has already been installed, just the flywheel, cover and disc can be replaced as a set.
• REMINDER: NEVER attempt to resurface the flywheel assembly.
• Always advise the customer to operate their clutch system as outlined in the Owner’s Manual “Starting and Operating / Manual Transmission” section.
• Always use the proper grease (Nichimoly N-130, Conoco-Philips Multiplex Red #2 or Subaru p.n. 000041000) when lubricating the contact points of the release bearing and related components as specified in the Service Manual. (See TSB 03-78-17 for more related information.)
