CL 120177

Frequently Asked Questions

Q: What Clark electric lift trucks use the CL 120177 idler caster?
A: The CL 120177 is an original Clark OEM idler caster designed as a direct replacement component for Clark electric lift equipment. This is a support caster that rolls freely and does not drive the truck. Confirm your exact truck model and year against Clark parts documentation to verify this caster is correct for your equipment.

Q: What material and durometer is the CL 120177 made from?
A: The CL 120177 is constructed from polyurethane with a 95A durometer hardness rating. This Shore A hardness level delivers a balance of traction, wear resistance, and load support typical of Clark idler casters for warehouse and light industrial duty in dry to moderate conditions.

Q: How does the CL 120177 differ from the CL 120177-XL?
A: The CL 120177 uses standard polyurethane at 95A durometer. The CL 120177-XL uses Poly XL 97A polyurethane, which is harder and more wear-resistant. If your equipment originally came with the CL 120177, confirm any upgrade to CL 120177-XL against your truck documentation to ensure proper load and steering characteristics.

Q: What is the typical lifespan of this idler caster?
A: Polyurethane idler caster lifespan depends on load, floor conditions, and usage frequency. Typical industrial duty is 1 to 3 years before visible tread wear or flat-spotting occurs. Cold storage, wet floors, and heavy loads accelerate wear. Regular visual inspection helps identify when replacement is needed to maintain steering accuracy and prevent secondary wear on the truck frame.

Q: Can I substitute the CL 120177 with an equivalent part from another brand?
A: The CL 120177 is the Clark original equipment part. For compatibility and warranty purposes, always use the OEM Clark part number or a verified equivalent. Verify dimensions, durometer rating, and mounting interface before substituting to ensure proper fit and load capacity.
