1991 LEGACY SERVICE MANUAL CORRECTION


The cylinder head resurfacing (grinding) specification listed in the 1991 Legacy Service Manual MSA5T9106A (October 1990A), contains a typographical error.

Section 2-3, Page 35 (W5C3) lists the grinding limit as O.1 mm (0.004").

The correct specification is 0.3 mm (0.012"). The 1990 Legacy Service Manual (G201BE April 1989) is correct.

Please make pen and ink changes to your 1991 Legacy Service Manual.
