Frequently Asked Questions
Q: What is the relationship between CL 1201776-XL and CL 120177-XL?
A: These are two distinct Clark part numbers. The CL 1201776-XL is a separate idler caster assembly from the CL 120177-XL. Both use Poly XL 97A at 97A Shore durometer for wear resistance. Always verify your equipment documentation against the exact part number required to avoid ordering an incompatible caster.
Q: What are the material specifications of the CL 1201776-XL?
A: The CL 1201776-XL idler caster is constructed from polyurethane elastomer with 97A Shore durometer hardness. This higher hardness rating provides enhanced abrasion resistance and load support compared to softer compounds. The polyurethane construction offers durability across warehouse, dock, and light industrial environments.
Q: Which Clark electric lift trucks require the CL 1201776-XL caster?
A: The CL 1201776-XL is designed as a replacement caster for specific Clark electric lift truck models. Confirm your truck model number and serial range against Clark service documentation to verify this is the correct caster for your equipment. Using the wrong part number can affect steering geometry and load handling.
Q: What performance advantages does the 97A durometer provide?
A: The 97A Shore durometer hardness resists compression, abrasion, and flat-spotting better than softer compounds. This results in longer caster lifespan, improved steering precision, and reduced vibration from uneven tread wear. In high-utilization fleets, the 97A compound reduces downtime from caster replacement cycles.
Q: How does load support differ between the CL 1201776-XL and standard-durometer alternatives?
A: The 97A polyurethane in the CL 1201776-XL maintains load capacity and rolling resistance more consistently than softer compounds as the caster ages and tread wears. Harder polyurethane deflects less under load, providing stable steering and even brake engagement throughout the caster lifespan. This is particularly important in high-load applications or extended-shift operations.
