Model A Ford Brake Cross Shaft

[Guest Hal Davis (MODEL A HAL)]

Does anyone know the proper diameter of the ends of the service brake cross shaft of a Model A Ford? I am refering to the area just inboard of the bellcranks where the bushings mount.

As a general thought, why not weld up and turn down the ends to fit the new bushings, minus a few thou for grease? You'd want to match the end to the bushing anyway, even if you somehow came up with the original factory diameter it might need dressing to fit the replacement bushing. <BR>Here's another free tip: Although there are probably hundreds of vendors that'll sell you "will fit" parts like bushings, you might be better off going to your local bearing house and buying the size you want to fit the application. An added plus is that you can usually get an oilite bushing for greater life (introduced by W.P. Chrysler in 1931, I think). I don't sense that this car is going to be vying for major gold, so the originality guys would probably not bother you over non-stock bushings.

Thanks, Bill. I was debating whether to buy standard size bushings or the repair kit with a sleeve to go over the worn area. Mine are not worn bad. I ordered the standard and will check the fit. If it is too loose to suit me, I will weld it up and turn it down. Oilites won't work in this particular case, as the outside is spherical rather than cylindrical. As for originality, the originals were steel with a woven insert. I'm not sure if they are still available, but I think I prefer the bronze type anyway. Less chance she'll seize to the shaft. Thanks again.<P>Hal
