Starter Motor for Komatsu FD40 Forklift - 24V, 11-Tooth, OSGR

Fits Komatsu FD40 lift trucks with the 4D52 diesel engine, 1985 onwards

This starter motor is built to OEM specifications as a direct fit and function replacement for the Komatsu FD40 lift truck fitted with the 4D52 diesel engine, from 1985 onwards. It replaces Komatsu 600-813-3240 and carries Lester reference 17376.

It is an OSGR (offset gear reduction) type starter, rated at 24V and 4.5kW with an 11-tooth clockwise-rotation drive, supplied as a complete unit ready to fit in place of the original part.

Industrial starter electrical systems vary between manufacturers, so we recommend checking your original starter's dimensions, voltage and mounting pattern against this listing before ordering. This unit is bench tested before dispatch to confirm correct output and rotation. OSGR-type starters use an offset gear reduction stage to deliver higher cranking torque than a standard direct-drive unit, making them well suited to the heavier compression loads found in Komatsu diesel engines.
