Forklift Starter Motor QDJ1409E-P 490B-51000 — Xinchai C490BPG / A490BPG / A498BPG / A495BPG 0.8KW 11-Tooth Slow Starter
This forklift starter motor part number QDJ1409E-P (cross-references 490B-51000-1, 490B-51000) is a Kingstream OEM 0.8KW 11-tooth slow starter for Xinchai C490BPG, A490BPG, A498BPG, and A495BPG 4-cylinder diesel engines in forklifts, construction equipment, and engineering machinery. This is a gear-reduction slow starter design that provides higher cranking torque at lower current draw compared to direct-drive starters — the internal planetary gear reduction multiplies motor RPM into higher torque at the pinion gear for reliable cold-weather diesel engine starting. 0.8KW output, 11-tooth pinion gear. Alloy construction at 6.32kg net (7.5kg gross) with 32×18×12cm neutral packaging. 1-year warranty (within 1.5 years). MOQ 1 piece. Payment by T/T deposit, Western Union, or PayPal. Machinery test report and video inspection provided. Kingstream OEM quality for Xinchai diesel engine fleet operators.
INSTALLATION PROCEDURE: Step 1 — Disconnect the battery negative terminal. Step 2 — Remove any access panels or covers blocking the starter. Step 3 — Disconnect the main battery cable and solenoid trigger wire from the starter terminals. Step 4 — Support the starter and remove the mounting bolts from the bell housing. Step 5 — Remove the old starter. Step 6 — Verify the new starter matches the old unit in mounting flange, pinion tooth count (11T), and electrical connections. Step 7 — Install the new starter with bolts hand-tightened, then torque to specification. Step 8 — Reconnect main cable and solenoid wire with clean tight connections. Step 9 — Reconnect battery and test. For slow starters, verify the gear reduction mechanism operates quietly and the pinion engages fully before the motor energizes. 1-year warranty. Kingstream OEM.
SYMPTOMS OF STARTER FAILURE: Clicking solenoid with no cranking, grinding noise from worn pinion or flywheel ring gear, slow cranking despite good battery, starter spinning without engine engagement, intermittent operation, and burnt electrical smell.
