The 1152-475WPA-1131 Crownwheel & Pinion Set assembly (ref. Figure 4.1) has
been replaced by 1152-475WPB-1131 Crownwheel & Pinion Set assembly (ref.
Figure 4.2). This is due to the creation of a new specification 1152-475WB-1131
Crownwheel to reflect changes in the manufacturing process.

All gearbox rebuilds from 07/07/15 onwards will be fitted with the new Crownwheel &
Pinion Set assembly as standard, unless otherwise notified.
