Product Overview
TM Coupling Hub 14x42 Teeth is a heavy-duty power transmission component used in transit mixers (concrete mixer trucks). It provides reliable torque transfer between the hydraulic pump shaft and the drum gearbox drive line in demanding construction and RMC plant applications.
This is the inner alloy steel hub with 42 external curved teeth that mates inside a nylon/polyamide curved gear flange — not a catalogue screenshot. Stock units show machined face marking 42/14 (42 teeth / 14 spline) for quick identification.
Google results for TM coupling hub 14x42 are mostly IndiaMART listings and AI overviews without dedicated supplier pages with real photos and video. This listing is built for workshops, fleet maintenance and export buyers who need fitment confirmation from New Delhi.
Typical replacement reasons: worn external teeth, damaged splines, cracked hub after high torque shock, or coupling vibration after flange wear. Send a photo of your removed hub and mixer brand before ordering.
