This SLEEVE MAINSHAFT is precision-machined for direct fitment over the Bajaj Tricab's mainshaft, with its inner bore diameter, outer wall thickness, and running surface finish accurately toleranced to maintain a controlled sliding fit and correct concentricity with the shaft axis. Functionally, it acts as a protective and bearing-locating surface over the mainshaft, maintaining consistent rotational support and shielding the underlying shaft from direct wear, and if the bore clearance widens or the running surface scores, it results in radial play, abnormal shaft wear, and eventual misalignment within the gearbox assembly. Supplied in authentic Bajaj green-box packaging with a hologram genuinity verification strip, this sleeve mainshaft is manufactured to maintain precise shaft support and long-term dimensional stability.
