Replacement Motor Brushes

This Ridgid 44540 motor brush assembly comes as a pack of two and fits Ridgid threading machines including the 1233, 300 series, 300 Compact, 300/300A Power Drive, and 535 series. It replaces original brushes on compatible pipe and bolt threading equipment to restore motor function.

Wear Part Maintenance

Carbon brushes wear down through normal commutator contact and must be replaced to maintain consistent motor torque. Fresh brushes reduce arcing, lower electrical resistance, and keep the threading machine running at its rated performance without excessive heat buildup.

Direct Fit Installation

The set matches Grainger part numbers 1VXG8, 3FE64, 3RY43, and 3Z987 as well as manufacturer model numbers 15682, 41855, 41910, 66947, 67182, 93287, and 96497. No additional hardware or adapters are required for the listed Ridgid machines.

Questions about this item

How do I install the 44540 motor brushes on my 300 Compact threading machine without damaging the holders?

Remove the old brushes, align the new 44540 brushes with the holder slots, and seat them fully; the step most people skip is checking that the spring presses squarely on the brush top before closing the cover.

When will the 44540 brush set need replacement on a 1233 pipe threading machine?

Replace the 44540 set when brush length wears down to the minimum mark stamped on the carbon or when the 1233 machine shows sparking at the commutator during operation.

What limit appears first during continuous threading with the 44540 brushes on a 535 machine?

Carbon wear reaches the minimum length limit before the motor insulation degrades, so the 44540 brushes will need changing once the stamped wear line is visible.
