Optimizing heavy-duty power generator systems requires precise, durable replacement parts. For professional fleet managers and maintenance engineers rebuilding the heavy industrial Perkins 4000 Series (including 4006, 4008, 4012, and 4016 models), having a perfectly matched combustion setup is critical to preventing blow-by and oil consumption.
Our premium OEM-standard Liner Kits provide direct-fit reliability, pairing the durable piston SE901BA (SE901 BA), the wet cylinder sleeve SE72E (SE72 E), and the high-tension ring pack 552359 (also compatible with 552-359).

Our dedicated technical support team helps fleet operators:
Excessive crankcase pressure, sudden heavy engine blow-by, and blue smoke coming from the exhaust are classic symptoms. This happens when the sealing surface between the wet cylinder liner SE72E and the running piston rings 552359 has worn past standard limits, letting compression escape into the oil pan.
Always ensure proper cooling system cleaning to prevent rust scale buildup around the wet sleeve. Uneven heat transfer causes local hotspots, breaking down the lubricating oil film and leading to direct metal-on-metal wear between the SE901BA piston crown and the liner wall.
Our assemblies feature an OEM-standard tri-metal structure for superior structural reliability, built to perform seamlessly in demanding high-load operations. It is widely trusted by repair shops and equipment fleets globally to return engines to original specs without premium pricing.
