Synchronizer ring to gear flank clearances (Y16M-D 6MT)

1st/2nd/3rd gears: inner ring ≈0.03858–0.06378 in (0.98–1.62 mm); middle ring ≈0.02677–0.07559 in (0.68–1.92 mm); synchronizer ring ≈0.03465–0.06772 in (0.88–1.72 mm). 4th/5th: ≈0.0315–0.06299 in (0.80–1.60 mm). 6th/reverse: ≈0.03465–0.05984 in (0.88–1.52 mm).1st/2nd/3rd gears: inner ring 0.98–1.62 mm; middle ring 0.68–1.92 mm; synchronizer ring 0.88–1.72 mm. 4th/5th: 0.80–1.60 mm. 6th/reverse: 0.88–1.52 mm.

Set the ring evenly in its gear and measure the ring-to-gear-flank clearance around the entire circumference with a feeler gauge. Each of the first three rows applies to all first, second and third gears. Replace the ring if outside specification. Printed inch limits are coarse and sometimes inconsistent; metric controls. Normally aspirated NB2 6MT only; actual 2003 evidence, other 2001–2005 years inferred.
