Frequently Asked Questions
Q: What is the 850-139-183-004 and what does it do?
A: The 850-139-183-004 is a Raymond electrical panel-mounted assembly that combines an hour meter and battery discharge indicator (BDI) for electric forklift trucks. It monitors totalized operating hours and real-time battery status on a single integrated display.
Q: What voltage range does this hour meter and BDI assembly operate at?
A: The 850-139-183-004 is rated for 24VDC to 36VDC systems, which covers most electric lift truck applications including Raymond, BT, and Clark models in this voltage range.
Q: What are the cross-reference part numbers for the 850-139-183-004?
A: Cross-compatible part numbers include BT 301445-000 and CL 448375 (also listed as CL 7000601). Verify your specific equipment model and voltage before ordering to ensure proper fitment.
Q: Which electric lift truck models are compatible with this assembly?
A: This part fits Raymond electric forklifts and other brands that use compatible components including BT (Bt Forklifts) and Clark models operating in the 24VDC to 36VDC range. Check your truck manual for the part number to confirm compatibility.
Q: How long does the hour meter and BDI function typically last?
A: Lifespan depends on usage and environmental conditions. Panel-mounted electrical assemblies typically operate reliably for the life of the forklift if kept clean and dry. Exposure to moisture, corrosion, or vibration can shorten lifespan. Regular inspection of connections and display clarity is recommended.
Q: What is the difference between the Raymond designation and manufacturer part number?
A: The Raymond designation is RA 850-139-183-004. The manufacturer part number is 850-139-183-004 without the Raymond prefix. Both refer to the same assembly. The alternative format RA850139183004 removes spaces and is used for database and cross-reference searches.
