CumminsSealing O-Ring Cummins Engine 6C – Engine 6CT – Engine 6CTA
O-Ring Seal Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
It is located between the oil pump and its housing or fitting, providing a static seal between mating components and preventing leaks of oil or other fluids in the circuit where it is installed. It also appears in the section on the lubricating oil system/oil pump, but the exact location may vary depending on the CPL and configuration.
Observed on 6C 8.3 / 6CT / 6CTA, ISC 8.3, QSC 8.3, ISL 8.9/9, QSL 8.9/9, QSB 6.7, and ISB 6.7 engines.
We always recommend checking the ESN and CPL in the Cummins OEM catalog, because the same O-ring is used across different engine families, and the quantity and location may vary depending on the engine configuration.

CumminsRear Crankshaft Seal Kit Cummins Engine 6C – Engine 6CT – Engine 6CTA / 6CTAA
Rear Oil Seal Kit Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3 / 6CTAA 8.3
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.

CumminsRear Crankshaft Seal Kit Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
Rear Main Seal Kit Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
The kit provides a seal at the rear of the crankshaft, preventing engine oil from leaking at the point where the crankshaft exits the engine block toward the flywheel/transmission housing. It is therefore installed at the rear of the engine block, on the flywheel side. The sealing component is typically made of a technical elastomer that is resistant to oil and high temperatures, combined with metal support/reinforcement elements.
Compatible engines: 4B, 4BT, 6B, 6BT, 6C, 6CT, 6CTA, ISB, QSB, ISC, QSC, ISL, QSL
However, we recommend checking the ESN/CPL before the sale: not all configurations within the same engine family necessarily use the same oil seal.

CumminsFront Crankshaft Seal Kit Cummins Engine 6C 8.3 – Engine 6CT 8.3 – Engine 6CTA 8.3
Front Oil Seal Kit Cummins Engine 6C.83 – Engine 6CT 8.3 – Engine 6CTA 8.3
The kit is fitted to the front of the crankshaft, at the front gear housing/front cover. Its main function is to prevent engine oil from leaking around the crankshaft whilst it is rotating. The oil seal is normally made of an oil- and heat-resistant elastomer with a metal support ring.
Used on the 6C 8.3, 6CT 8.3, 6CTA 8.3, ISC 8.3, QSC 8.3, ISL, QSL / QSL 9 engines.
Final compatibility must always be checked using the engine’s ESN and CPL, or the Cummins OEM catalogue. Within the QSL family, there may be variations depending on the year, configuration and CPL; therefore, the engine family alone does not guarantee 100% suitability.
