I popped the roll pin out of the clutch arm. Soaked it, hammered it, stuck it in a vise and muscled it, no budge. What's the trick?

Our mechanics always use heat to unstick things and lots of it.

It was a royal PITA for me. I soaked it with PB. Then tried that acetone/ATF fluid mix. Lots of heat. BF Hammer. No dice. Finally after several days I think I had it in a vice with a drift the right size. Used the floor jack handle as my cheater bar and finally got it to budge. After that, it was just a matter of time. This one can really suck, no doubt about it. It was harder than the shift bar linkage pin I did last year, and I thought THAT was PITA (IMG:style_emoticons/default/hissyfit.gif)

I popped the roll pin out of the clutch arm. Soaked it, hammered it, stuck it in a vise and muscled it, no budge. What's the trick? Are you punching the pin from the correct side,if I rememeber right theres one end and then the other,Elliot that's sounds like the sort of reply you would get on Pelican,no disrespect to Bruce but many can only afford DIY. Its not like we own cars that are worth that much ...sad really. My assembly was all pretty and painted up but little else found most bushes gone or very worn,replaced with bronze bushes all good. |

I can see the confusion now. I'm trying to get the arm off to do new bushings, clean and repaint and stuff.
Nothing against bdstone, I just like to do my own stuff. |

I popped the roll pin out of the clutch arm. Soaked it, hammered it, stuck it in a vise and muscled it, no budge. What's the trick? Yes heat. Heat it until the bushings catch fire and burn them out. If you hammered on the end of the shaft you will mushroom it and never get it out. Hammer the shaft back in by placing the clutch shaft end with the lower clutch arm over the spread vice jaws. Hit straight down just enough to get it to move. Now inspect the end to see if it is mushroomed. If so file or grind down the flare on the end. Then clamp the other end of the clutch shaft in the vice and using a large adjustable wrench twist the lower clutch shaft wist back and forth until you can get at least 1/4 turn of movement. Don't use to much force in twisting. I have twisted the hole shaft and stretched the round roll hole oval. If that is not clear I can take pictures tomorrow. I have had a few out of the couple hundred I have rebuild where I could not get the lower clutch to move. I then grind through the lower clutch arm with an angle grinder. If you have to do that I can supply a replacement part. Last resort send it to me and I will rebuild it. Bruce |

When I rebuilt mine I had the same issue and ended up just taking it to a machine shop. They got it out in 10 minutes and didn't charge me anything.

Here are some pics. Pound the shaft into the clutch arm with the vice jaws spread just wider than the shaft diameter. You only need to move it about MM. Grind down the flared end.
Clamp either end of the shaft on the vice and twist the other end with a long wrench. Work back and forth until it turns more easy. Clamp the shaft flange in the vise. Have a helper use two screw drivers to pry on the lower shaft while you twist the lower clutch flange. put the upper clutch pedal back in to have more leverage. Attached thumbnail(s) |

Sounds like rebuilding your cluster turned into a Cluster Fuch!
Good luck! (IMG:style_emoticons/default/drunk.gif) |

That job that is rarely worth doing yourself. The brute force and heat required to get that &*(&^*ing thing apart is nuts. Top 10 on the "914 projects that suck" list. Send it to Bruce, he will send you a nice purty one back.

To the OP: did you get it apart? did the pictures make sense?
Thanks for all the kind words. After doing a couple hundred you learn a few tricks. I like building them. Some I get apart in ten minutes. Some in an hour and the one in the picture never. I realize my service is not for everyone and do not mind helping with advice helping other rebuild theirs. I also do them for 911 up through 1989 including the G50 type sets. Bruce |

Mine is not nearly that rusty so I'm optimistic. Is someone making replacement springs? Mine is missing, though I think I'll be engineering a helper spring for the big 9" clutch. |
