This main shaft is precision-machined with multiple bearing journal diameters, a splined output section for gear engagement, and a hardened keyway slot along its length to ensure accurate rotational alignment and torque transfer through the Tricab's transmission assembly. It functions as the primary drive shaft carrying power from the clutch through the gearbox to the output stage, and any wear, scoring, or runout along its journals or spline teeth can result in gear slippage, excessive noise, or premature bearing failure within the gearbox housing. Supplied in authentic Bajaj green-box packaging with a hologram genuinity verification strip for complete peace of mind.
