This bulletin is being revised to add warranty information. This bulletin also cancels and supersedes Corporate Bulletin Number 336404. Please discard
Corporate Bulletin Numbers 336404 and 636407 (Section 6 - Engine).
This bulletin is being issued to revise the previous generator service procedure in Section 6D3 of the Service Manual. The revised procedure deletes the
need to remove the drive axle and generator splash shield. Instead, the intermediate steering shaft lower pinch bolt is removed. Then the intermediate
shaft is separated from the steering gear. A jacking fixture is installed to support the rear of the frame. The two rear frame bolts are removed and the
frame is then lowered no more than 100 mm (4 in.), gaining access to the generator.
Refer to the proper vehicle Service Manual and other Service Bulletins for specific sub-component removal, installation and tightening specifications.
