[QUOTE="Dave_Nevada, post: 1497892, member: 29749"] I pulled the ZF6 because of a short clutch release problem along with noisy gears and grinding the gears while shifting. While down there, I noticed the fingers on the pressure plate were worn and the infamous 7.3 input shaft was toast. I also noticed somebody put that ****ty sleeve modification on the input shaft you can buy on the Internet- and in reality, it’s a band-aid on a gusher wound. It works for a while, but you’re going to be back in there because the problem isn’t solved. The problem is the input shaft needle bearing loses lube and become a grinding device on your input shaft. Do you like pulling your trans yearly? Then use that input shaft sleeve mod kit and you’ll get your wish. Like I said, while doing my inspection, I noticed the input shaft bearing was crap. The turbo up-pipes were also leaking. First, I pulled the tranny, then took off with the flywheel to hammer out the needle bearing. I liked how that flywheel was designed, no bearing inside the crank! I didn’t have to buy a pilot bearing puller! However, instead of putting back the ‘problem generator’ needle bearing, I installed an Oilite solid bearing made for a 1968 Mustang with a toploader. It fit perfectly. Sometimes ‘old skool’ really is better. Input shaft bearing # Dorman 690-039 or Ford C8AZ 7600-A, D2AZ 7600-A or E3TZ 7600-A. Putting in an oilite bearing means no more chewed up input shafts. Since the bearing is softer than the input shaft, the bearing becomes the sacrificial surface, NOT the input shaft. [/QUOTE]
