for Lambretta 150 LI Grade B – decent repair Product description We have the original gearbox parts/cogs for the licence produced SIL Lambretta models from India available. The original Italian gearbox components have been out of production for many years, making these SIL items an obvious and economic solution. The ratios of the 3rd & 4th gears are closer on the Indian scooter than with the Italian DL/GP models. It is advantageous to find the correct gear ratios, especially with tuned. To check/adjust the end float clearance of the assembled gear shaft a thrust washer feeler gauge (#60824000) is also available. Do not forget to order a new selector cruciform and fresh gearbox oil! OEM numbers (for comparisons): 19030006 (INNOCENTI)
