Frequently Asked Questions
Q: What are the wheel dimensions and material specifications for the 3012970?
A: The 3012970 has a cast iron core and polyurethane tread rated at 95A hardness. It includes sealed precision ball bearings, precision axle, and mounting hardware with a zerk lubrication fitting for maintenance access.
Q: Which Hyster models is the 3012970 compatible with?
A: The 3012970 is designed for Hyster electric pallet jacks, with confirmed compatibility to W40Z and W45Z series models. Verify your specific equipment model and specifications before ordering to confirm fitment and compatibility with your truck.
Q: What cross-reference part numbers exist for the 3012970?
A: Cross-reference part numbers include HY3012970, HY-3012970, HY-3012970-A, and equivalent part number HY 3012970-A. All these designations refer to the same component. Verify against your equipment documentation before ordering.
Q: Why does the 3012970 include a zerk fitting if the bearings are sealed?
A: The zerk fitting allows optional bearing lubrication if seals show wear or bearing noise develops during extended service. Under normal conditions, sealed bearings do not require lubrication. Use the zerk fitting only if you observe bearing degradation or extended equipment life is critical to your operations.
Q: What is the expected service life of the 3012970 wheel assembly?
A: Service life depends on load weight, floor surface, maintenance frequency, and operational hours. The polyurethane 95A tread resists standard indoor wear effectively. Sealed bearings extend service life significantly. Replace the wheel when tread depth decreases visibly, flat spots develop, or bearings become noisy despite maintenance.
Q: Is the cast iron core on the 3012970 prone to corrosion?
A: Cast iron cores can show surface rust in high-moisture environments such as cold storage or wet areas, though this does not affect function unless severe pitting occurs. For wet or cold storage applications, consider wheels with non-corrosive cores. Standard indoor use does not expose cast iron to significant corrosion risk.
Q: What maintenance is recommended for the 3012970 assembly?
A: Inspect tread depth and bearing condition regularly. Use the zerk fitting to apply grease if bearings show wear signs. Keep wheels clean and free from debris. Store in dry conditions to minimize corrosion on the cast iron core. Replace wheels when wear becomes visible or handling performance declines.
