CA The hand clutch on my 1951 CA is frozen. I've been soaking it with brake cleaner and Marvel Mystery Oil but does not seem to be helping. Is it okay to use a MAPP torch on it? Anything else I should try? I guess my last resort will be to take the axle off and take the clutch apart. I assume it's rusted and gunked up from the disintegrated brake pad. The engine is running great since we first got it running on New Year's Eve Day. Coolant was leaking out of the water pump, so I got a new one on order. I've removed the disintegrated brake pads (a messy job) and have new pads on order. The engine's running without a rebuild (other than having a machine shop valve job) so luckily this project is a restoration rather than a rebuild. |

The shop manual may have some useful hints: http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf" rel="nofollow - http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf Gerald J. |

There is also an excellent post concerning the CA Hand Clutch in the knowledge base section of this site. Sounds to me that will be your next step to free it. And even if you do you will have to rebuild it. Sandy Lake can probably get you the parts. Perhaps you may get lucky and be able to obtain one on e-bay. Surprising what turns up there Good Luck!

| Bill is spot on in my opinion, you need to take it apart and clean the ramps,balls and install new springs and disk. Also may need to machine the wear surface in order to make it work right. Also I have seen them bolted together so they won't slip, you may find that has been done. |

My personal recommendation is to contact Rick Corder (314-479-7757) and send the whole thing to him. His work is first class and it will be done right. I send all my clutches, pressure plates and brakes to him. I have never been disappointed with his work.

| Thanks for all the advice. Since it's frozen so tightly it may have been purposely bolted that way to keep it from slipping. |

That happened often. |
