Intermediate Shaft Bearing wear
I originally posted this in the 911 Techincal forum and it was suggested that I post to this forum.
I have just disassembled my 85 930 (with 120,000 miles). The main and rod bearings look great. The intermediate shaft bearings are worn to the copper in the upper one half of both bearing shells. Since the chains pull to each side and the gears wold seem to have little up or down pressure, I am a stumped as to why the bearings would be worn in this manner. Any suggestions? Thanks.
