Frequently Asked Questions
Q: What is the RA 850-137-166 chain sheave used for?
A: The RA 850-137-166 is an OEM chain sheave (pulley) designed for steer arm assemblies in Raymond 101 walkie electric pallet trucks. It acts as a mechanical guide to direct and control the steering chain movement for directional control.
Q: Which serial number ranges does the RA 850-137-166 fit?
A: The RA 850-137-166 chain sheave is designed for Raymond 101 walkie electric pallet trucks with serial numbers 3000 to 7499. Verify your truck serial number before ordering. Trucks outside this range may use a different sheave design.
Q: What material is the chain sheave made from?
A: Chain sheaves for steering applications are typically made from steel or cast iron to withstand chain tension and repetitive movement. The material provides durability and resists wear from chain friction over extended use.
Q: What symptoms indicate the chain sheave needs replacement?
A: Replace the chain sheave if steering becomes sluggish or unresponsive, you hear grinding or squealing from the steer arm, the steering chain slips or jumps off the sheave, or the steering wheel feels loose. These conditions indicate sheave wear or damage affecting steering control.
Q: Is the RA 850-137-166 a wear item?
A: Yes, chain sheaves are consumable items that wear over time due to chain friction and tension. Life expectancy depends on operating hours, steering frequency, and maintenance. Regular chain inspection and lubrication extend sheave life. Replace the sheave if groove wear becomes excessive or the chain no longer tracks properly.
