Medium Duty Starter Drive with Clockwise Rotation. for Reliable Engine Cranking in Various Industrial & Automotive Applications.

the Story of Starter DriveEarly starter drives used simple gear engagement without clutch protection. the drive, introduced in the 1910s, used inertia to engage the gear. modern designs employ solenoid-controlled engagement for timing. material evolution from basic steel to specialized alloys improved durability. today's designs incorporate helical for quieter operation.Part Number121555C91,8MJ4172T,10479028,10479156,135162,263819C91,20-2383T91,0R2187,RE41754,V61094,1219523H91,820013422,R0461127,V90563,E821132X,70620350,RE51579,BSO7188,0R2191,70675686,262762C91,0R4259,820013408,E-821124X,RE10464,70622235,820013409,820013417,10461214,R0461178,RE10321,536-011-M91,107717A1,3945661,0R2190,8MJ176,0R4267,R0461125,RE24305,R0461179,V90562,0R2697,307822R92,V1114241,686696441312,70620382,V1114238,E-821126X,135160,135163,173006,2132X10461057,V1114249,R0461126,V102746,820013427,820013433,V1114243,20-1297T91,135161,260493C91,8MJ4172P1,20-1295T91TypeStarter driveRotationClockwise Product TypeStarter driveTeeth on Drive11 Weight3 How to Install Starter DriveDisconnect the negative terminal. the starter motor from the engine. disassemble the starter motor end cap to the drive assembly. slide the drive off the armature shaft. install the new drive, ensuring proper alignment of the and snap . reassemble the starter motor and reinstall it on the engine.Function of Starter DriveWhen the ignition key turns, the starter drive extends its pinion gear to mesh with the flywheel gear. it transmits rotational from the starter motor to turn the engine . once the engine starts, the overrunning clutch immediately disengages to the engine from driving the starter motor, protecting it from overspeed damage.
