Vintage Kart; Enduro Kart; Margay Gearbox

Description

Vintage Margay gearbox. This was used on an enduro kart years ago. It has had some modification to the mounting arm (see pic 4), probably for clearance. Doesn't affect operation. Bearings spin nicely and seem fine. Seals look good also but I haven't filled it with lube so I can't tell for sure. This has the optional "enduro range" drive gears with a 20 tooth input gear, 25 tooth intermediate gear and 75 tooth output gear (versus 20-20-80 for the standard "sprint range" drive gears). By my calculations this will change the ratio of the gear sets by 75%. For example with an 8.0-1 gear set you would get a final ratio of 6.0-1. It comes with a 4.6-1 gear set (3.45-1 actual final ratio).
