Description

Overview

Jaylec Starter Motor 12V Thermo King is a 12V replacement starter for selected Thermo King refrigeration applications that use a 9-tooth drive and 35mm pinion. It sits in the starting circuit, so matching the flange size, mount spacing and rotation matters before installation. When a reefer unit cranks slowly or fails to start, this part gives workshops a direct replacement option within the listed interchange family.

Features

• 12V starter motor with 2.0kW output
• 9-tooth drive with 35mm pinion and clockwise rotation
• 95mm flange diameter with 120mm mounting centres
• Built for selected Thermo King and Yanmar-based reefer applications within the listed interchange range

Specifications and Materials

Jaylec Starter Motor 12V Thermo King uses a reduction gear starter layout with a 95mm flange, 9-tooth pinion, clockwise rotation and 222mm overall length. The mounting pattern uses 2 x 13.5mm holes on 120mm centres, so buyers can compare the old starter before ordering. Part number: 70-3445-1.

Compliance and Safety

Disconnect battery power before removal and check that the cable ends, earth path and solenoid feed are clean and secure during installation. Also inspect the flywheel or ring gear if the old starter has damaged teeth, because repeated clash can shorten starter life. If the reefer has an ongoing hard-start fault, test battery condition and cable voltage drop as well.

Trailer Applications

This starter is used on selected trailer refrigeration systems where dependable crank speed matters during cold starts, restart cycles and routine fleet servicing. It suits applications built around this 12V, 9-tooth, 35mm gear pattern, so it is relevant for Thermo King reefer units that share the listed interchange family.
