Overview – KIT, LINER-JP-KC 4089364 Series
Built to Cummins specifications, the KIT, LINER-JP-KC 4089364 serves Cummins engine overhaul as the cylinder liner kit; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
A cylinder liner kit that provides the bore the piston runs in, with the supporting seals and components for a correct installation. The liner is the surface the rings seal against, and its finish and fit decide compression, oil control and liner cavitation life.
Applicable Models & Applications
Fitted to Cummins engine overhauls specifying this liner kit. Match the liner bore, flange and seal set against your engine or the parts book – liner kits vary with the block and the overhaul level.
Maintenance & Replacement
Fit the kit with cleaned, inspected block bores and the correct installation tools. A liner pressed in dirty or off-square cracks the block and fails the seal it was meant to make.
Replace the full seal and support set together. A liner with a reused seal weeps coolant into the crankcase, and the symptom is an oil that climbs and a level that falls.
Torque and sequence the hold-down to specification. A liner drawn up on one side distorts the bore and the rings never seat evenly, so it smokes from day one.
Keep the correct liner kits for your engine on the shelf. They are consumable in any overhaul, and an engine open on a liner is an engine waiting on a kit.
