Compatibility
| Application | Fitment requirement |
|---|---|
| GY6 125cc / 150cc engines | Matching rear final-drive gearbox cover, shaft arrangement, bearing sizes and mounting pattern |
| 157QMJ, 161QMK, 152QMI, 1P61QMK, YN1P57QMJ, 1P52FMI, 154FMI, JJ157QMJ, 1P57QMJ, BN157QMJ, BN161QMK-A; other QMJ, QMK and QMI applications | Only where the gearbox-cover configuration matches; verify applicable 169cc setups against the original cover |
Compare the cover outline, mounting holes, dowel locations, bearing dimensions and shaft layout with your original assembly before ordering. Belt length and engine-code letters alone do not establish gearbox-cover fitment. Use a fresh matching gasket during assembly and follow the engine service specifications for installation and final-drive oil refill.
