Frequently Asked Questions
Q: What is the PR 200065 brush box assembly?
A: The PR 200065 is an OEM replacement brush box assembly for Prime Mover electric lift truck main traction motors. The assembly includes the corrosion-resistant housing body, preloaded compression springs, and precision-machined brush contact surfaces. It is a complete brush holder unit designed for direct integration into the motor.
Q: Which Prime Mover models use the PR 200065 brush box assembly?
A: The PR 200065 is specified as an original equipment component for Prime Mover electric lift trucks with compatible main traction motor designs. Verify your equipment model number and serial range before ordering, as brush box assemblies vary significantly across motor generations and voltage systems.
Q: What materials are used in the PR 200065 assembly?
A: The PR 200065 housing body is cold-rolled steel with corrosion-resistant coating to prevent rust and degradation in warehouse environments. The assembly includes carbon steel compression springs per SAE J403 grade specification. The brush contact surfaces are precision-machined to maintain consistent clearances and electrical contact.
Q: What are the spring specifications in the PR 200065?
A: The PR 200065 includes preloaded carbon steel compression springs rated for continuous brush pressure across the full range of motor operating speeds. Spring tension is calibrated to maintain optimal brush contact force without excessive wear on the commutator or armature surfaces. Springs are selected per SAE J403 material standards for durability and consistency.
Q: When should the PR 200065 brush box assembly be replaced?
A: Replace the PR 200065 assembly when springs lose preload tension causing reduced brush contact pressure, when the housing body shows visible corrosion or damage, when brush contact surfaces become worn or scored, or when the assembly can no longer maintain consistent electrical contact. Worn brush box assemblies reduce motor efficiency and increase motor temperature.
