WESPC ZZ90212 Crankshaft for Perkins 1004, 4.236, 4.248 Diesel Engine Rebuild

Application:

WESPC ZZ90212 crankshaft is designed for Perkins 1000 series 4-cylinder diesel engines, including models 1004.40, 1004.40T, and 1004.42. These engines are widely used in agricultural tractors, construction machinery, and industrial generator sets. The crankshaft converts linear piston motion into rotational force, ensuring smooth power delivery, mechanical balance, and long-term durability under high-load conditions. It is a critical component for maintaining engine timing, compression integrity, and vibration control.

Generator sets:

Commonly installed in 80–150 kVA diesel generator platforms powered by Perkins 1004 series engines. The WESPC ZZ90212 crankshaft supports consistent combustion pressure and rotational stability during continuous operation and peak load cycles. It contributes to fuel efficiency and reduced vibration in commercial and industrial backup power systems.

Construction machinery:

Suitable for JCB equipment such as 3CX backhoe loaders and 415 loaders powered by Perkins 1004.40 and 1004.40T engines. The crankshaft maintains torque output and mechanical integrity in high-vibration environments, supporting reliable performance in off-road and heavy-duty applications.

Agricultural equipment:

Used in Massey Ferguson and Landini tractors equipped with Perkins Phaser series engines. The crankshaft ensures stable piston synchronization and reduced wear during extended field operations, contributing to long service intervals and engine longevity.

Industrial systems: Applied in stationary pumps, compressors, and mechanical drives requiring high engine stability and rotational precision. The ZZ90212 crankshaft supports continuous operation in demanding industrial environments, helping maintain engine balance and lubrication integrity.

Technical specifications:

Forged steel construction with counterweights for rotational balance. Rear flange with 10 bolt holes and lip-type seal; front snout splined and keyed with 3 bolt holes. Designed for use with machine-split connecting rods. Compatible with Perkins 1004.40, 1004.40T, and 1004.42 engines. Weight approx. 45 kg. Manufactured with precision-machined journals for optimal oil film retention and wear resistance.

Material & performance features:

Produced using high-strength forged steel with advanced machining for dimensional accuracy and surface finish. Engineered to maintain crankcase balance, reduce vibration, and support long-term engine reliability under thermal and mechanical stress. Manufactured under ISO-certified quality control standards.

Interchange part number:

ZZ90212; cross-referenced with 4223939M91, ZZ90202, ZZ90225, ZZ90238. Verified fitment for Perkins 1000 series engines used in agricultural, construction, generator, and industrial applications.
