Frequently Asked Questions
Q: What are the specifications of the HY 4078433 rocker arm assembly?
A: The HY 4078433 is a rocker arm assembly manufactured by Hyster for electric lift trucks. This assembly measures 670mm in length and is galvanized for corrosion protection. The 670mm length distinguishes it from other rocker arm variants in the Hyster parts catalog.
Q: How does the 670mm rocker arm differ from the 560mm model HY 4078432?
A: The HY 4078433 is 110mm longer than the HY 4078432. This difference affects lift mechanism geometry and is engineered for specific Hyster models. Using the wrong length rocker arm will cause improper mast alignment and lift inconsistency. These are not interchangeable without equipment modifications.

A: The HY 4078433 is designed for specific Hyster electric lift truck models that require a 670mm rocker arm. Different Hyster model lines and lift heights use different rocker arm lengths. Verify your equipment model and serial range to ensure correct fitment before ordering.
Q: Does the galvanized coating require maintenance?
A: The galvanized coating is maintenance-free under normal warehouse conditions. However, in harsh environments with salt spray, high humidity, or corrosive chemicals, the zinc coating may thin over time. Inspect for white rust or bare metal showing through the coating as signs of coating degradation.
