Frequently Asked Questions

Q: What equipment does the 12VDC forklift shift control solenoid fit?
A: This solenoid is designed specifically for Heli and TCM 2-3 ton electric lift trucks. It controls hydraulic transmission shift operations electromagnetically. OEM equivalent part number is 34E-10BY-12V-KSD. Verify your truck manufacturer and tonnage rating before ordering.

Q: What material is this solenoid constructed from and what does it weigh?
A: The solenoid features a die-cast aluminum alloy body with electromagnetically actuated internal components. Net weight is 1.6 kg. The aluminum construction provides durability while maintaining lightweight design for compact mounting in lift truck control systems.

Q: Can this solenoid be cross-referenced to other part numbers or manufacturers?
A: Yes, this solenoid has OEM equivalent part number 34E-10BY-12V-KSD. This 12VDC, 1.6 kg unit is a direct replacement for Heli and TCM transmission shift solenoids. Always cross-reference by OEM number and voltage specification when ordering equivalents.

Q: What are the failure symptoms of a worn solenoid in a Heli or TCM electric lift truck?
A: Common symptoms include hesitation or delay during gear shifts, inability to shift into forward or reverse, jerky transmission engagement, or complete shift failure. If the truck fails to respond to shift commands, the solenoid should be tested before replacement to confirm it is the fault.

Q: What voltage does this solenoid require and what happens with voltage fluctuations?
A: This solenoid operates at 12VDC nominal voltage. Battery voltage drops below 10 volts or charging system failures above 14.5 volts will cause erratic solenoid performance or premature failure. Maintain stable charging and battery systems for reliable operation.
