Raymond Drive Unit Helical Pinion Gear – RA1154671

This helical pinion gear is built by Raymond for the drive unit on 4150 and 4250 stand-up counterbalanced forklifts, where it transmits torque from the drive motor to the wheel. As a helical gear, its angled teeth engage progressively rather than all at once, which spreads the load across more tooth surface than a straight-cut gear and runs quieter under the constant torque a drive unit experiences during acceleration and direction changes.

Pinion gears in a drive unit are subject to continuous meshing load, and over enough duty cycles the tooth surfaces can pit, chip, or wear thin at the contact point, which shows up as increased gear noise or play in the drive unit before a full failure. Replacing the pinion at the first sign of that wear protects the mating gear it drives against from picking up the same damage.

At 0.7 pounds, this is a compact precision-machined component sized for its position inside the drive unit housing rather than a standalone driveline part. Fitment is specific to the Raymond 4150 and 4250 stand-up counterbalanced platforms, and ordering by the manufacturer part number ensures correct tooth count and engagement for that drive unit.
