help with CA hand clutch problem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Clutch was sliping under a load, removed final drive and clutch assmbly. Everything looks ok, maybe it was adjusted to tight? We are going to replace disk while its apart and fix leaking seals, replace oil soak brake as well. Problem is I cant get the brake drum/ clutch hub off the outer axle shaft. Made a puller, hit axle shaft with a big drift and hammer and it wont move at all. I pulled the bronze bush out and soaked with P oil, shouldnt have to remover snap ring since it keeps drum from being pushed by clutch towards outboard side. Is it just rusted that bad or am I missing something. Thanks for any help, JM

	Link to an earlier article on repairing the CA hand clutch: http://www.allischalmers.com/new/forum/forum_posts.asp?TID=9207&KW=ca+hand+clutch&title=hand-clutch A slipping clutch is a result of asny or all of the following: oil soaked friction disc, worn friction disc, weak springs, worn disc balls, too much gap between the friction disc and pressure plates when clutch is engaged. Probably best to rteplace the friction material and install new springs. After you have it all reassembled, place it under a shop press and compress it. Have noted that most have 1/8-1/4" gap when compressed. I then remove metal from the three ears so that I have approx 0.020" gap when compressed. I have two PDF files with pictures showing how I rebuild a hand clutch and can email them to you if you PM me with your regular email address.

	Hey Greg, You remembered grinding the 1/8" off the ears. You know we stumbled on that answer but after that solved the problem we never ceased to do it. Seemed to correct the problem. Course we replaced springs, clutch, balls, and ball dishes before we ground. Those brake drums can be very hard to move. We had problems in the 50's much less 60 years later. Good Luck! Bill Long ps: Let us know how it goes.
