# Drive gear thrust clearances (Y16M-D 6MT)

Canonical URL: https://miatatorque.com/spec/y16m-drive-gear-thrust-clearance/

Applicability: NB 2001–2005 (BP-Z3, 6MT) — 2003 factory component-manual evidence; other years inferred within the 2001–2005 normally aspirated NB2 family. Does not infer MSM.

Confidence: fsm

Thrust clearance
(mm {in})
1st 0.15–0.40 {0.006–0.015}
2nd 0.10–0.45 {0.004–0.017}
3rd 0.10–0.35 {0.004–0.013}
4th 0.10–0.35 {0.004–0.013}
6th 0.10–0.40 {0.004–0.015}
Reverse 0.10–0.45 {0.004–0.017}

Always confirm against your factory manual. Match every restriction and follow all stages and procedure notes. Disputed claims must not be automatically resolved. The complete record below preserves every printed unit, source claim and procedure.
