RST40 Product Design Changes – ABIB-0510R3
GEAR/PINION and RING GEAR NUT/BOLT CHANGE:
The actual pinion design change was described on page two of this bulletin. In addition to that change the ring gear
fasteners were also commonized to use the same fasteners as the RS404. When using the replacement gear/pinion kits
for any “Original” design axle or any axles built with the original design gearing you must use the correct nut and bolt kit
during reassembly. Refer to the charts and kit numbers below.
This bulletin contains product information.
