WESPC ZZ90238 Crankshaft for Perkins 1004 4.238 A4.236 A4.248 4-Cylinder Part

Application:

WESPC ZZ90238 crankshaft kit is designed for Perkins 1104C-44T and 1104C-E44TA diesel engines, which operate with a 4-cylinder configuration and a displacement of 4.4 liters. This crankshaft kit includes the main rotating shaft and associated components required for precise power transmission and engine balance. It plays a critical role in converting the reciprocating motion of pistons into rotational energy, ensuring smooth torque delivery and mechanical stability under continuous and peak-load conditions.

Generator sets:

Commonly installed in 60–150 kVA diesel generator platforms powered by Perkins 1104C series engines, including FG Wilson P50E2S, Genmac G100PO, and other globally deployed units. The ZZ90238 crankshaft kit supports continuous-duty operation and load transitions by maintaining engine balance and minimizing vibration. Its robust design contributes to long-term reliability in both standby and prime power systems.

Construction machinery:

Suitable for compact track loaders and skid steer equipment such as the Gehl 7810 and Terex PT-100G, where high-impact resistance and rotational stability are essential. The crankshaft kit enhances durability in hydraulic drive systems and supports consistent power delivery across rugged terrain and variable load conditions.

Agricultural equipment:

Compatible with Massey Ferguson tractors including models 491, 492, 5445, 5455, 5460, 6445, 6455, 6470, and 6460, as well as McCormick MC115. These machines rely on the ZZ90238 crankshaft kit for efficient torque conversion, reduced vibration, and dependable engine operation during heavy-duty fieldwork, towing, and harvesting.

Industrial power systems: Applied in stationary diesel-driven systems such as hydraulic pumps, compressors, and mechanical drives where crankshaft integrity and thermal resistance are critical. The kit ensures secure coupling with flywheel assemblies and maintains precise alignment under continuous load conditions.
