  • Material: Integrated rigid steel outer shell + FKM fluorine rubber sealing lip with internal tension spring
Key Features
  1. Metal outer frame for interference fit, stable installation without deformation under high-speed rotation

  2. FKM fluororubber resists high working temperature, engine oil and fuel chemical corrosion, anti-aging and wear-resistant

Product Description

Part number 142-5867 is the front crankshaft oil seal specially matched for CAT 3412 V12 large industrial diesel engine. It is installed at the front nose of crankshaft inside the timing gear housing, used to block lubricating oil leaking out from the crankshaft front end.

Widely applied on CAT 3412 marine propulsion engines, stationary generator sets and heavy-duty industrial power units. Aged, hardened or incorrectly installed front crank seal will lead to continuous engine oil dripping onto timing gears, drive belts and cooling system, resulting in oil shortage, belt slipping and accelerated wear of peripheral components. It is a necessary replacement part during engine timing system overhaul and full top-end rebuild.

We supply parts for Kubota, Cumm ins, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, Vol vo, Deutz, Doosan, Daewoo, John De ere, Scania, Hyundai, JCB etc.

FAQ
  1. What does INSTALL DRY mean on the seal?

    Do not apply grease or engine oil on the sealing lip during installation, dry pressing is required to extend service life.

  2. Is this seal only for CAT 3412 engine?

    Primarily designed for CAT 3412, also compatible with related series engine models with the same part number specification.

  3. What faults will a failed front crankshaft seal cause?

    Front engine oil leakage, contaminated drive belts, reduced engine oil level, insufficient lubrication for timing gear assembly.

  4. What is the advantage of FKM rubber material?

    Excellent high temperature resistance, oil resistance and oxidation resistance, suitable for long-term heavy-load operation of large diesel engines.
