Frequently Asked Questions
Q: What Yale models are compatible with the YL 5170858-04 forward/reverse switch?
A: The YL 5170858-04 is a forward/reverse directional switch for Yale electric lift trucks. Confirm your truck model and manufacturing date with Yale documentation. Some models may use alternative switch part numbers, so verify the exact switch type required before ordering.
Q: What is the voltage and electrical rating of the YL 5170858-04 switch?
A: The YL 5170858-04 switch is designed for Yale electric lift trucks with standard forklift battery voltage (typically 24VDC or 48VDC depending on truck configuration). Verify the voltage rating against your equipment specifications before installation.
Q: What symptoms indicate the YL 5170858-04 switch has failed?
A: Signs of switch failure include loss of forward or reverse function, intermittent directional changes, or the truck failing to respond to lever position changes. If one direction works but the other does not, the switch contact points are likely worn or corroded.
Q: What is the operating lifespan of the YL 5170858-04 forward/reverse switch?
A: Typical lifespan is 3 to 5 years under normal material handling duty. High-frequency directional changes and exposure to moisture or vibration may reduce lifespan. Replace when electrical continuity fails in either forward or reverse position.
Q: Is the YL 5170858-04 switch the same as the YL 517085804?
A: The YL 5170858-04 and YL 517085804 are different part numbers and may not be interchangeable. YL 5170858-04 uses a hyphenated designation while YL 517085804 does not. Verify the exact part number on your equipment before ordering, as substitution may cause function issues.
