The M10060 Caterpillar Seal & Wear Sleeve Installer Kit – Brake Saver is a precision engine service tool set specifically engineered for installing front and rear crankshaft seals and wear sleeves on Caterpillar 3400 Series engines equipped with a BrakeSaver unit. This kit provides technicians with all the necessary components to seat seals and wear sleeves accurately, concentrically, and to OEM-style depth—ensuring reliable sealing performance and long-term engine durability.
BrakeSaver systems on Caterpillar 3400-series engines are used to utilize engine oil pressure to actuate a separate braking mechanism, and these assemblies include additional sealing surfaces that must be installed carefully to prevent leaks, premature wear, and hydraulic contamination. The M10060 installer kit serves as a professional alternative to OEM Cat 8T-2855 tooling and includes fixtures such as a rotor holding plate (an alternative to Cat 5P-8718) to support precise installation operations.
This installer kit is ideal for diesel engine rebuild shops, fleet maintenance facilities, and professional technicians performing BrakeSaver reseal and overhaul procedures. By using a purpose-built installer rather than improvised methods, technicians can significantly reduce the risk of seal distortion, wear sleeve misalignment, and damage to expensive engine components.
