The ATD 7404 Clutch Jack is a professional-grade transmission and clutch service tool engineered to handle the demanding requirements of heavy-duty truck and fleet maintenance operations. With a robust 500 lb. capacity and an impressive lift range from 16-1/2" to 42", this clutch jack provides the strength, stability, and precision alignment capabilities necessary for efficient removal and installation of 14" and 15-1/2" clutch assemblies. Built by ATD Tools, a trusted name in professional automotive equipment, this jack delivers the durability and versatility shops depend on for high-volume transmission work.
Professional Heavy-Duty Clutch Service
Servicing heavy-duty truck clutches requires equipment that can safely support substantial weight while providing the precise alignment needed for successful installation. The ATD 7404 answers that challenge with a 500 lb. load capacity that accommodates most medium and heavy-duty truck clutch assemblies. The hydraulic lifting mechanism operates smoothly through a full range of 16-1/2" minimum height to 42" maximum height, giving technicians the working range needed to handle a variety of vehicle types and transmission configurations.
The jack's solidly constructed frame provides stable support throughout the entire service procedure, while the swivel casters enable easy positioning under the vehicle and smooth maneuvering during clutch alignment. At 176 lbs., this jack has the substantial weight and low center of gravity necessary to remain stable while supporting heavy clutch assemblies at full extension.
Precision Multi-Axis Alignment System
What sets the ATD 7404 Clutch Jack apart from standard transmission jacks is its sophisticated multi-directional alignment system. The hub pilot bearing shaft features a 1" diameter and accepts the included 1-3/4" and 2" splines, accommodating different clutch disc configurations. The spline assembly rotates a full 360°, turns side-to-side, and tilts vertically, giving technicians complete freedom to achieve precise clutch-to-flywheel alignment without wrestling with the weight of the clutch assembly.
This multi-axis adjustment capability dramatically reduces installation time and frustration. The conveniently located release valve allows for controlled, gradual lowering when needed, while the 360° rotating pump handle enables hydraulic operation from any position around the jack. Technicians can make fine adjustments to height and angle while maintaining optimal working position, resulting in faster, more accurate clutch installations with less physical strain.
