Crown Motor Insulator CR083707 – CR83707

Inside a Crown traction or pump motor, an insulator like this one separates conductive parts and blocks current from shorting between components that must stay isolated. Crown cataloged this insulator for its position in the motor, where holding that separation keeps the circuit intact under load and vibration.

An insulator is replaced when it is cracked, degraded, or damaged, since a failed insulator can let current jump where it should not and short the motor circuit. This is the Crown replacement, installing in place of the original to restore proper isolation.

Confirm which motor and position it fits against the insulator being replaced before installing, since Crown uses more than one insulator across its motor designs.
