JD30 Forklift Differential Assembly

The JD30 type differential assembly is a complete drive axle differential designed for JD30 series and compatible 3-ton internal combustion counterbalance forklifts. This assembly distributes engine torque from the transmission to the left and right drive wheels while allowing them to rotate at different speeds during cornering, preventing tire scrub and driveline binding. The differential uses a forged steel case with precision-machined side gears and spider gears, all supported by tapered roller bearings for smooth, durable operation under heavy load conditions.

The ring gear mounting flange is machined for precise bolt-on attachment to the final drive ring gear, and the axle shaft side gears feature internal splines matching OEM axle shaft dimensions for direct bolt-in replacement. The spider gear cross-shaft is hardened and ground for wear resistance, and the differential case halves are bolted together with high-strength fasteners torqued to specification. The assembly is designed for straightforward drop-in replacement of the worn or damaged factory differential without modifications to the axle housing.

Direct fit for JD30 series forklifts and cross-compatible with select HELI CPCD30, Hangcha CPCD30, and other 3-ton domestic forklifts using JD30-type drive axles. Always replace the differential carrier bearings and axle seals during differential replacement. Fill the axle housing with the specified gear oil (typically 80W-90 GL-5) to the correct level after installation.
