1. Put gasket (5) and air compressor (3) in position on timing gear housing (2). Install two bolts and washer (4) that fasten the air compressor and cover (1) to the timing gear housing. Tighten bolts (4) to a torque of 100 20 N m (75 15 lb ft).--------------- END SUPPLEMENT ---------------Correct installation of the air compressor is essential to help prevent loosening of the compressor and bending the timing gear cover. Incorrect installation can result in a loose compressor, oil leaks, and/or a cracked timing gear cover. Use the following procedure to install the air compressor:
