Overview – KIT, VALVE SEAL 4011514 Series
4011514 is the CUMMINS KIT, VALVE SEAL used on Cummins diesel engine valve stem seal replacement. We can supply this line as well as the related family numbers listed below, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
4011514 is the CUMMINS valve seal kit that renews the valve stem seals on the engine, containing the seals in the original material with the correct interference fit for the valve guides. Each seal is moulded to the OEM profile so it meters the oil down the stem correctly and stops oil burning through the guides. The kit is packed with the quantity needed for one complete valve set.
Applicable Models & Applications
This kit is used on CUMMINS diesel engines where the original 4011514 valve seal specification applies, including the engine families that share the valve and guide size. Confirm the valve stem diameter and the guide bore against the seals in the kit before ordering. The related 4011516 and 5406078 cover the other seal sizes in the series, and we can confirm the correct kit from your engine model.
Maintenance & Replacement
Replace the valve stem seals when the engine shows oil consumption through the guides or blue smoke at start-up. Fit the seals with the correct installation tool to avoid tearing the lip, and lubricate the stem lightly before assembly. Check the guides for wear at the same time, and replace any worn guides before fitting new seals.
