Weldment Tandem Pivot - Parts for Pallet Jacks

Frequently Asked Questions

Q: What is the E-6643 tandem pivot weldment?
A: The E-6643 is a welded assembly that connects the front and rear axles on tandem-steer electric lift trucks. It allows both axles to turn together for precise four-wheel steering control and improved maneuverability in tight spaces.

Q: Does the E-6643 fit other pallet jack and truck brands?
A: The E-6643 tandem pivot weldment is compatible with select Crown, Toyota, and Raymond tandem-steer models. Cross-reference your equipment serial number and model year to confirm fitment, as tandem configurations vary by manufacturer.

Q: How is the E-6643 constructed?
A: The E-6643 is a pre-welded steel assembly designed to factory specifications. The weldment consolidates the pivot connection into one rigid component, reducing assembly complexity and improving steering responsiveness compared to bolted alternatives.

Q: What maintenance does the E-6643 weldment require?
A: The E-6643 requires minimal maintenance. Periodically inspect for cracks or separation at weld points, check that all mounting bolts are tight, and verify steering feels consistent and responsive. Do not attempt to weld repairs; replace the assembly if cracks develop.

Q: What is the typical service life of the E-6643?
A: The E-6643 tandem pivot weldment typically lasts 4 to 6 years in standard warehouse use. Lifespan extends longer in light-duty operations and shorter in high-intensity or outdoor environments. Replacement becomes necessary if steering play develops or welds crack.

Q: How do I know if the E-6643 needs replacement?
A: Replace the E-6643 if you notice loose or unpredictable steering, clunking sounds when turning, visible cracks in the weld seams, or if the truck drifts during straight-ahead operation. These symptoms indicate weld fatigue or separation.
