I just split my CA because I ran out of adjustment on releasing the clutch. Sure enough, my fingers on the clutch plate are showing lots of wear. 5 years ago when I had the tractor split before I did not replace anything except the disk. I think that was a big mistake. At any rate, I have a new clutch kit for the 8 1/2 inch this one requires. Included in the kit is a new release bearing. After removing my old one, I looks like I may need to press the old one out of the assembly. Is that correct? Also, once I have the new parts installed, is there some trick to setting the adjustment of the pedal or is it just a trial and error until the pedal travel is right? Thanks for all you experts out there. Dave ------------- Dave Fullmer McKenzie, TN |

| That's about it, unless you have excessive wear in the linkage. Then you'd probably want to build up the worn spots. It would make everything work together better. I don't remember what the free travel should be set at but someone chime in on that. Leon R Cmo |

Thanks Leon, So my main question is do I have to press out the old release bearing from the casting? ------------- Dave Fullmer McKenzie, TN |

I don't really see any excessive wear in the pedal linkage. Also, I am not sure how to remove the old pilot bearing.

Well, I just took an other look, there is no way it could be pressed out so I just took a hammer to it and tapped it off the housing. It didn't take much tapping and now the old throwout bearing is off the housing. When the kit comes, it looks like a carefull tapping back on will do it. I also checked the grease zerk for accepting of grease and that is OK also. Just a matter of waiting for the parts to put it back together now. ------------- Dave Fullmer McKenzie, TN |

Do I dare use the alignment tool for that? Or would mess up the tool? ------------- Dave Fullmer McKenzie, TN |

I've made a jig to bolt to the back of the engine after installing the clutch. Then I set the fingers to the jig and put the tractor back together. Perfect free play every time.

Wait a minuet, you mean the fingers them self are adjustable? The only free play that I know of would be on the rod that connects to the foot pedal. ------------- Dave Fullmer McKenzie, TN |

| Dave, if you have a Rockford clutch here you go. You want three threads to protrude thru. the clutch rod fork. Then check the clearance of the forks and turn the adjusting screw if needed so you get a 1/4" clearance on all of them with a tolerance .010". Measure at the end of the shift forks, and don't forget to tighten the lock nuts. Sounds easy doesn't it? Oh, you did find the inspection plate? Leon R Cmo |

No inspection plate on my CA. There is a 2 inch dia hole in the bottom of the housing right underneath the grease zerk, but I sure can't find any way to adjust the fingers once the tractor is together again. I would think the pressure plate would be factory set to be in parallel plane to the flywheel. Then turn the clutch pedal rod for the right clearance.
