IMPROVED SILENT DIRECT DRIVE ENGAGEMENT & ROLLER SPIGOT BEARING. Origin. To facilitate changing into direct gear. Experimental Test Report. The scheme is to use an internal gear in place of direct drive gear jaws. This is similar to the scheme used on the 20 HP. and all modern Phantom gearboxes. Road Test Report. Fitted to 14-EX. It is noticeably easier to change gear. 10,000 miles will be completed before any cars are delivered. X No. 8310 Drawing No. LeC. 2111 Part List L.O.P.
