Minarelli horizontal / vertical transmission crankcase cover TNT

TNT transmission crankcase cover for Minarelli Horizontal and Vertical engines.

This part is part of the secondary transmission assembly, enclosing the housing where the gears responsible for transmitting motion to the rear wheel operate.

In addition to sealing the assembly, the crankcase must keep the shafts and their support points correctly positioned. A warped, cracked cover or one with damaged housings may cause lubricant leaks, play, or incorrect gear operation.

Replacing it restores the geometry and sealing of the transmission assembly, especially after breakage, impact, or deterioration of the original housings.
