Frequently Asked Questions
Q: What Big Joe electric lift truck models use the BJ 900136 motor spring?
A: The BJ 900136 spring is designed for Big Joe electric motors #01642 at 12 volt, specifically for models serial number 333583 and later. Confirm your motor part number and serial range match before ordering this spring.
Q: What function does the BJ 900136 spring perform in the motor assembly?
A: Motor springs maintain brush contact pressure, apply return force to mechanical linkages, or provide tension in motor assemblies. The BJ 900136 is specific to motor #01642 function. Do not substitute with springs from other motors.
Q: What are the specifications of the BJ 900136 spring?
A: Spring specifications include coil diameter, wire gauge, free length, and spring constant. These dimensions are critical for proper motor function and cannot be guessed. Verify exact specs against the motor assembly before ordering.
Q: Can the BJ 900136 be used as a replacement for springs in other Big Joe motors?
A: No. The BJ 900136 is engineered for motor #01642 12 volt only. Using the wrong spring can cause brush misalignment, reduced contact pressure, motor noise, or failure. Do not cross-apply to other motor models.
Q: How often should the BJ 900136 spring be replaced?
A: Motor springs wear over time due to mechanical cycling and can lose tension or break. Replace the BJ 900136 if the motor exhibits noise, vibration, reduced brush contact, or if the spring shows visible cracking or deformation.
