[ROVERNET - UK] Gearbox changes

Internally, your "F" gearbox is a bushing type, while the 71 will be 
a needle roller type. That means that the internal mainshaft parts 
are not interchangeable. The needle roller gearboxes (suffix H and 
above) are better but (technically) slightly nosier due to the many 
more rotating bits. The early bushing type gearbox had problems with 
the bush for 2nd and 3rd gear breaking, but unless you came across a 
low mileage original all of those have long since broken and been 
fixed.

Yours
Vern
