Frequently Asked Questions
Q: What does the CR 74657-025-A Load Wheel Assembly contain?
A: The CR 74657-025-A is a complete sealed assembly consisting of the load wheel, axle shaft, bearings, seals, and fastening hardware. This unit arrives fully assembled and lubricated from the factory. It is a direct bolt-on replacement for the entire load wheel system.
Q: How does the CR 74657-025-A compare to the CR 74657-020-A?
A: Both are sealed wheel assemblies, but the CR 74657-025-A and CR 74657-020-A are sized for different Crown truck models or load ratings. The -025 variant has a different wheel diameter or load class than the -020 variant. Do not interchange them. Verify your truck specification before ordering.
Q: Is the CR 74657-025-A bearing serviceable or sealed for life?
A: The CR 74657-025-A bearing is sealed for life and is not user-serviceable. Factory lubrication is sealed inside the bearing housing. If bearing noise develops or seal damage is visible, the entire assembly must be replaced. Re-lubrication in the field is not possible.
Q: What environmental conditions affect the CR 74657-025-A lifespan?
A: The assembly performs well in standard warehouse conditions (55 to 75 degrees Fahrenheit, moderate humidity). Exposure to extreme cold, salt spray, or harsh chemicals accelerates seal degradation and bearing corrosion. In cold storage, expect a reduced service life of 1.5 to 2 years versus 3 to 4 years in standard conditions.
