WESPC 2418F704 Rear Oil Seal for Perkins 1104C 44T E44TA Diesel Engine

Application:

WESPC 2418F704 rear crankshaft oil seal is designed for Perkins 1100 and 1200 series diesel engines, including models 1103C-33T, 1104C-44T, 1104C-44TA, 1104D-44TA, 1104D-E44TA, 1204E-E44TA, and 1204F-E44TTA. These engines are widely used in agricultural tractors, construction machinery, generator sets, and industrial systems. The rear crankshaft seal plays a critical role in preventing engine oil leakage at the flywheel end of the crankshaft, maintaining lubrication integrity and protecting the clutch housing from contamination.

Generator sets:

Commonly installed in 60–150 kVA diesel generator platforms powered by Perkins 1104 and 1204 engines. The WESPC 2418F704 seal ensures tight oil containment at the rear crankshaft interface, supporting long-term engine operation and reducing maintenance frequency in commercial and industrial backup power systems.

Construction machinery:

Suitable for Caterpillar and JCB equipment such as 315CL, 414E, 424D, 428E, 430D, and 444E powered by Perkins 1104 and 1204 engines. The seal maintains a secure barrier between the crankcase and transmission components, preventing oil seepage and supporting consistent engine output in high-vibration environments.

Agricultural equipment:

Used in Massey Ferguson tractors including models 431, 451, 461, 491, 5435, 5445, 5455, and 5460. The seal supports stable crankshaft rotation and prevents oil loss during extended field operations, contributing to engine cleanliness and long service intervals.

Industrial systems:

Applied in stationary pumps, compressors, and mechanical drives requiring high engine stability and oil system integrity. The 2418F704 seal supports continuous operation in 24/7 industrial environments, helping to prevent oil leakage and maintain optimal lubrication performance.

Technical specifications:

Inner diameter 65.00 mm, outer diameter 80.00 mm, thickness 11.10 mm, weight approx. 0.05 kg. Manufactured using high-grade elastomeric materials with precision molding for dimensional accuracy and sealing efficiency. Designed for press-fit installation into the rear crankshaft housing. Compatible with Perkins 1100 and 1200 series engine configurations.

Material & performance features:

Produced using solvent-free, asbestos-free sealing compounds with high resistance to oil additives, temperature fluctuations, and mechanical vibration. Engineered to maintain sealing pressure and elasticity over extended service intervals. Manufactured under ISO/TS16949-certified standards for global diesel engine applications.

Interchange part number:

2418F704; cross-referenced with Caterpillar 232-7449, JCB 02/202935, Massey Ferguson 4224762M1, Glaser P77470-01, and Reinz 81-45907-60. Verified fitment for Perkins 1103, 1104, 1106, 1204 series engines. Suitable for use in generator sets, agricultural equipment, construction machinery, and industrial systems worldwide.
