  Cylinder Liner Sealing Ring Cummins Engine QSL

  Seal, Rectangular Ring – Cylinder Liner Cummins Engine QSL 8.9 / QSL 9

  It is mounted in the lower section/seal area of the cylinder liner, between the liner and the engine block. It is part of the cylinder liner sealing system. Its main function is to seal the cylinder liner against the engine block, prevent coolant from flowing into unintended areas, prevent contamination between coolant and engine oil, and maintain proper sealing of the cylinder liner during the engine’s thermal cycles.

  Verified compatible Cummins engines: 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL 8.9/9, QSL 8.9/9.

  I recommend verifying compatibility using the ESN (Engine Serial Number), CPL, QuickServe/Cummins Catalog, cylinder liner number, block number/casting number, engine year/configuration, and a dimensional comparison of the ring.

  Piston w/Pin, Retainer & Rings Cummins Engine ISL

  Piston w/Pin, Retainer & Rings Cummins Engine ISL 8.9 / ISL 9

  This is a standard (STD) engine piston kit used primarily on Cummins ISL/QSL 8.9–9.0 L engines, featuring a two-piece piston. The kit is installed inside the cylinder block, connected to the connecting rod via the piston pin. Its function is to absorb the pressure generated by combustion, transfer the force to the connecting rod and then to the crankshaft, seal the combustion chamber via the piston rings, control oil consumption, and transfer part of the heat from the piston to the cylinder liner and the cooling/lubrication system.

  It is always a good idea to check the ESN (Engine Serial Number), CPL, the Cummins QuickServe/OEM catalog, engine model, horsepower/rating, piston type (1-piece vs. 2-piece), the number stamped on the cylinder head, and the dimensional comparison.

  Rear Crankshaft Seal Kit Cummins Engine ISL – Engine QSL

  Rear Oil Seal Kit Cummins Engine ISL 8.9 – Engine QSL 8.9 / QSL 9

  Rear crankshaft oil seal kit with a double-lip seal, designed for Cummins applications with a wet flywheel/clutch housing. Location: rear end of the crankshaft, transmission/flywheel side. Documented equivalent seal made of PTFE. Its function is to prevent engine oil from leaking from the rear end of the crankshaft, maintaining a seal during crankshaft rotation.

  The following are listed: ISB4.5, ISB6.7, QSB4.5, QSB6.7, 6C8.3, 6CT8.3, 6CTA8.3, ISC, QSC, ISL, and QSL for applications with a wet clutch housing. And on other engines: 4BT3.9, 6BT5.9, 6CT8.3, 6CTA8.3, 6CTAA8.3, and QSL9

  Always verify the ESN (Engine Serial Number), CPL, and wet/dry flywheel housing configuration, because the same engine may use a different rear seal depending on the configuration.
