Key Features

• Genuine OEM Construction — Manufactured to original Multiquip specifications, with u-joint sizing and pitch geometry matched exactly to the original assembly.
• Big U-Joint Design — Oversized u-joints provide increased torque transfer capacity and improved durability under the demanding load cycles of welder operation.
• Direct-Fit Replacement — Mounts using the same attachment points as the factory part, making installation straightforward on compatible DLW-series machines.
• Verified Fitment — Confirmed compatible with DLW300ES, DLW300ESA, DLW300ESA1, DLW400ESA4, and DLW330X2 diesel light welders.
• Pitch Control Integrity — A properly functioning twin pitch control maintains consistent blade or rotor pitch adjustment, directly affecting welder output stability and operational control.

The twin pitch control assembly is responsible for managing the pitch adjustment of dual rotating components within the welder, allowing the operator to regulate output and performance characteristics during operation. The u-joints within the assembly transmit rotational motion between shafts that are not perfectly aligned, absorbing angular variation while maintaining smooth, continuous drive. When the pitch control assembly wears or the u-joints fail, the operator loses the ability to make accurate pitch adjustments, which can result in erratic output, increased mechanical stress, and potential damage to connected drivetrain components.
