Frequently Asked Questions
Q: What is the PL 36-1170 brush box assembly?
A: The PL 36-1170 is a brush box assembly for electric lift truck starter motors. It contains four graphite-copper brushes with coil compression springs housed in a high-impact phenolic resin holder. This assembly is compatible with MDT, MDU, MDY, MEC, MEG, MEZ, MFB, and MHN series starter motors.
Q: What are the brush dimensions in the PL 36-1170?
A: The PL 36-1170 contains four graphite-copper brushes measuring 8.5 x 17.5 x 10 mm each. These dimensions are standard for the compatible starter motor series and must match your motor for proper fitment.
Q: Does the PL 36-1170 supersede or replace older Prestolite part numbers?
A: Yes. The PL 36-1170 supersedes Prestolite part numbers 36-1178, 36-1275, and 36-67. It also replaces equivalent parts MDL1064SS, S2375, 151-20000, and BH1093. The OEM reference number is 5560-6505.
Q: What is the material of the brush holder in the PL 36-1170?
A: The brush holder is constructed from high-impact phenolic resin. This material provides electrical insulation, durability against vibration, and heat resistance required for electric lift truck starter motor applications.
Q: What role do the coil compression springs play in the PL 36-1170?
A: The coil compression springs maintain consistent brush pressure against the commutator. This pressure ensures continuous electrical contact between the brushes and commutator as the brushes wear during normal motor operation.
Q: How do I verify that the PL 36-1170 is compatible with my lift truck starter?
A: Check your lift truck documentation for the starter motor series designation (MDT, MDU, MDY, MEC, MEG, MEZ, MFB, or MHN). Confirm your motor series is listed in the compatibility range before ordering. You can also verify the cross-reference part numbers including OEM reference 5560-6505.
