A leak at the rear often indicates that the 2037859 crankshaft seal has hardened or suffered from wear due to heat. If you notice oil pooling near the flywheel housing, it is time for an immediate replacement to avoid engine oil starvation and environmental contamination.
The 2037859 seal requires a clean, burr-free crankshaft surface. We recommend using the specific installation tool to ensure the seal is seated squarely. Improper seating is the leading cause of premature failure in heavy-duty diesel engines.
Answer: Our units feature an OEM-standard tri-metal structure and high-grade sealing lips. They are Trusted by repair shops & equipment fleets worldwide for maintaining Caterpillar engine integrity during full overhauls.
