About MAIN SHAFT - CM (4244531M02)

The MAIN SHAFT  CM 4244531M02 is a precisionengineered transmission component designed to deliver durable reliable power transfer in heavyduty agricultural and industrial gearboxes Manufactured from highstrength alloy steel and finished to close tolerances this main shaft forms the structural backbone of the gearbox assembly carrying gears bearings and synchronizers while transmitting torque from the input cluster to downstream gearing Its geometry  including machined journals keyways splines and thrust surfaces  has been optimized for uniform load distribution and minimal bending under peak load conditions ensuring long service life even under cyclical stresses common in farm and construction equipment

Attention to metallurgical quality is central to the 4244531M02 The shaft undergoes controlled heat treatment and quenchandtemper cycles to achieve a balanced combination of core toughness and surface hardness Critical bearing journals are ground to precision diameters and surfacehardened to resist wear while gear seating areas are machined to accurate concentricity to prevent misalignment and premature gear tooth wear Dimensional tolerances and surfacefinish specifications minimize vibration and noise contributing to smoother shifting and a quieter gearbox overall

Installation and maintenance are simplified by clear design features chamfered edges for easy gear assembly standardized keywayssplines for immediate compatibility with mating components and dedicated oilchannel features where applicable to ensure consistent lubrication The shaft is compatible with routine workshop service procedures and replacement intervals and its robust design reduces the risk of deformation or failure under shock loads

Quality control for each MAIN SHAFT  CM includes fulldimensional inspection hardness verification on critical surfaces and visual checks for machining defects The part is supplied with protective packaging to prevent corrosion and damage during storage and transit For aftermarket suppliers and maintenance shops 4244531M02 represents a costeffective OEMgrade replacement that restores gearbox integrity and performance while minimizing downtime
