Overview
Cylinder Liner 469-5312 is a commonly used spare part in construction machinery. We can supply all the original and replacement part numbers listed below, in stock or available on order — welcome to enquire by part number.
Applicable Models & Applications
These liners serve Caterpillar engine blocks, providing the bore surface the piston and rings work against. Suitable for the corresponding machine model and configuration — please verify the machine model, serial number and part number match before ordering.
Maintenance & Replacement
Measure liner bore and taper at every major overhaul; replace liners, or liner/piston sets, when wear exceeds the maker's limit or glazing/scoring appears in the ring travel. Early signs it may need attention: Rising oil consumption with a bluish exhaust on a hard-worked engine; A loss of compression that mirrors worn rings and a tapered bore, especially at a cold start; Coolant in the oil, which can follow a cracked or leaking liner flange seal.
Installation Essentials
Work on a clean machine with the engine off and the relevant system drained or depressurised as required, and confirm the part number against your machine model and serial number before ordering. Fit liner protrusion and, where used, a controlled press or sealant exactly as specified. Break-in new liners with the recommended oil and load schedule to seat the rings. After installation, run the machine and check for leaks, unusual noise or abnormal travel before returning it to service, and retighten where the manual calls for it after the first hours of operation.
