How YC6MK Differs From the Rest of the Range
- Shares its 145 mm stroke with the YC6MJ but runs a smaller 123 mm bore against the YC6MJ 131 mm. Liners and pistons therefore do not interchange between the two, while stroke-related parts may — check the nameplate carefully, the two are easy to confuse.
- Wet cylinder liners and a 17.5:1 compression ratio, both higher-spec than the smaller YC4D and YC6B engines in this range.
- Positioned for 200–330 kW generator sets, heavy trucks and coaches rather than mid-size construction equipment — no Chinese construction machine fitment was found for this specific branch, though the wider YC6M platform does appear on 5 t wheel loaders.
- At 10.338 L it sits in the same displacement class as the SDEC SC11CB (10.5 L), a useful reference if you run a mixed fleet.
Compiled from a genset manufacturer technical data sheet and validated against bore/stroke geometry (123 mm × 145 mm × 6 = 10.337 L, matching the stated 10.338 L). Yuchai part numbers are tied to the specific calibration rather than the series name, so quote against the full nameplate code and engine serial number.
