745843 Replacement Belts Replacement Belt for Solo Models 80 Teeth

Keeping a vintage 45CI Solo, Servi-Car, or XA model clean is a constant battle, but this belt drive kit from Samwel Supplies makes it a lot easier. Designed to fit neatly inside your stock primary cover, this kit replaces the messy primary chain with a front and rear pulley and a matching belt. The result is a much smoother, quieter ride and a primary that stays dry and oil-free. Just a heads-up from the workshop: we do not recommend installing this belt drive in conjunction with a Big Fix clutch bearing kit, as the tolerances are designed for standard setups. It is a great upgrade for anyone looking to modernize their Flathead's reliability while maintaining a stock outward appearance.
