Special High Ratios for Bentley. Herewith is a print of N.Sch.4123 (original to BY) which shows how we suggest the reverse shaft should be dealt with for the box which is of the same external shape as now. We have made the reverse shaft pinion separate from the shaft as we cannot pass it through the central division. It is also necessary for the reverse fork to be detachable from the rod. We have further reduced the diameter of the reverse shaft pinion to obtain more clearance between it and the 1st speed pinion. HUY. | ||
