A/C Man

Sorry, I didn't make it clear. The new bell housing is the same stack height as the old, so the spline and pilot bearing worked out fine. I made a shim to space out the slave cylinder. Several of the parts diagrams showed a 5 mm spacer behind the slave cylinder and Chrysler issued a service notice on the subject. With cnc equipment it is amazing that several million of these parts got made to the wrong size. The shim is of coarse no longer available. Not having cnc available, I used the "CBWAO" manufacturing tecnique (country boy with oxy aced). The software comes in 12 oz. cans and works about as well as some of the "high tech" junk coming from Detroit.

Ah Ite. I'm riding around in my '92 YJ with a new external clutch slave cylinder. After changing three internal cylinders I can pull this little 4 banger in my sleep. Everything worked out according to plan except most of the bolts had to be changed (no problem at home depot).After measuring the throwout bearing clearance I realized I needed way more than the 5 mm mounting shim. I burned a new one out of 3/8 plate--it measured about .360 when I got through grinding it clean. This gave me about .125 slack. The pedal feels normal and drives fine. Thanks for the info--especially the part numbers. My bell housing was marked "2001 cherokee" but it had the right part number and worked fine with the exception of the bolt lengths. Good luck with the automotive damper set up. That is some of the crummiest stuff I've ever seen air go through. I had the sheet metal artists replicate some of these parts a time or two. Seemed a shame to put that plastic junk back in considering how much work is involved. It is amazing what some of these guys can do with 26 ga. steel. My training and experience is more like 25 to 100 tons in hospitals but I've done my own auto A/C many times and I'll be glad to help if I can Thanks for the help Pal

Thank you sir. i'll let you know how it works out. If I can help anybody with thier a/c, I'd be glad to. 42 years as a heavy A/C mechanic in Alabama where we know a thing or two about hot weather.

There appears to be no spring to retract the throwout bearing away from the pressure plate fingers here. Am I missing something here ?
