Frequently Asked Questions
Q: What is the CR 117011 shim and where is it used?
A: The CR 117011 is a precision shim used in Crown PE 3000 Series drive assemblies. Shims are thin metal spacers that adjust alignment tolerance stack-up between axles, bearings, and wheel hubs.
Q: Why would I need to replace the CR 117011?
A: Replace the CR 117011 if you observe uneven bearing preload, wheel runout, lateral axle movement, or loose wheel assembly. Shim wear or loss allows excessive play that degrades bearing life and handling.
Q: Are shims cross-compatible between models or brands?
A: No. The CR 117011 is specific to Crown PE 3000 Series assemblies. Shim thickness and material are engineered for PE 3000 bearing preload and assembly geometry. Do not substitute with other brands or models.
Q: What happens if shim thickness is incorrect?
A: Incorrect shim thickness creates improper bearing preload. Too thin causes excessive play and early bearing failure. Too thick creates overpreload that increases friction, reduces wheel speed, and accelerates wear.
