GW 9135-AL

Frequently Asked Questions

Q: What is the main difference between GW 9135-AL and GW 9135-A1?
A: The GW 9135-AL has a 4.5 inch width while the standard GW 9135-A1 has 5 inch width. The AL (Alternative or Long-load variant) is designed for trucks requiring wider load distribution or mounting in a narrower chassis opening. Both have identical 3.25 inch diameter and 95A durometer rating. The narrower 4.5 inch width may fit applications where the 5 inch width does not clear guards or frame components. Always measure your wheel mounting space before substituting.

Q: Is the GW 9135-AL interchangeable with GW 9135-A?
A: The GW 9135-AL is listed as an alternate part number for GW 9135-A, meaning they are functionally equivalent for many applications. However, the width difference (4.5 inch versus 5 inch or other configurations) may not allow direct swap. Installing a narrower wheel in a wider mount creates axial play, allowing the wheel to shift sideways under load. Conversely, a wider wheel cannot fit a narrower opening. Verify physical dimensions before using as a substitute.

Q: What generic electric pallet jack models is the GW 9135-AL compatible with?
A: The GW 9135-AL is designed for generic electric pallet jack compatibility. Common models include standard 3000-4000 lb capacity jacks from unbranded or no-name manufacturers. Before purchase, confirm your jack manual specifies a 3.25 inch diameter wheel with 4.5 inch width. Do not assume your jack uses this size without verification. Measure the existing wheel or check the part label on your jack. Crown, Linde, and Toyota branded jacks typically use proprietary sizes and may not be compatible.

Q: How does the 95A durometer polyurethane affect grip and wear?
A: The 95A durometer rating is mid-range polyurethane hardness. It balances grip and durability. On smooth concrete, 95A provides adequate grip without slipping. On wet or oily floors, harder durometers (like 97A) perform slightly better. On rough concrete, 95A grips well while resisting chunking and tearing. Expect visible wear pattern (slight glazing and minor flattening) after 12-18 months of daily use. If your floor is slippery, consider upgrading to the GW 9135-XL (97A) instead.

Q: What tools and precautions are needed to install the GW 9135-AL?
A: You will need a hydraulic jack (minimum 2 ton capacity for most pallet jacks), a socket wrench or snap ring pliers, and a rubber mallet. Procedure: (1) Raise the jack so the wheel clears the ground. (2) Remove the snap ring from the axle using snap ring pliers. (3) Tap the wheel assembly off with a rubber mallet (do not strike the bearing). (4) Clean the axle and inspect for rust or burrs. (5) Tap the new wheel assembly on, ensuring the bearing hub seats fully. (6) Install the snap ring. (7) Lower the jack and test for wobble. Do not load the jack fully for 10 minutes after installation.

Q: Can the GW 9135-AL be repaired or are bearing assemblies sealed and non-serviceable?
A: The GW 9135-AL uses sealed precision ball bearings (typically 2RS or sealed cartridge style) and is not user-serviceable. Bearings cannot be repacked with grease or disassembled for cleaning. If the bearing fails, the entire wheel assembly must be replaced. Attempting to disassemble or re-lubricate the bearing will void any warranty and can destroy the bearing seals. Parts cost and labor make replacement more economical than repair.
