BF4L1011F BF4M1011 diesel engine spare parts cylinder liner piston kit for deutz liner kit 0427 1031

The DEUTZ BF4L1011F engine platform has two overlapping liner part numbers — 0427 1310 and 0427 1031 — which are often confused by buyers. Reference 0427 1031 features a different flange outer diameter and top protrusion design, primarily used in earlier BF4L1011F production batches or specific regional variants. As a China-based trading company, we do not assume compatibility. For every 0427 1031 inquiry, we request either the old liner flange measurement (70.2mm vs 70.8mm) or a photo of the cylinder block deck. The kit includes: four centrifugal-cast wet liners with induction-hardened bore, upper/lower Viton O-rings, flange gasket, and assembly lubricant. We also supply the 0427 1031 kit as a standalone item without pistons, allowing rebuilders to replace only worn liners due to cavitation or ovality. Unlike mass-market sellers, we bag each liner individually with the flange side marked to prevent upside-down installation. Sea freight consolidation available for mixed DEUTZ 1011 series orders.
