    Okay, I was sick for a few days and it took a while to get back to the brake/bearing issue. I cleaned the spindle and bearing surfaces and checked them with a vernier caliper. Both checked .750. I then examined the surfaces and could find no irregularities. I then got a worn piece of 320 silicon carbide abrasive paper and polished a little just beyond the threads. The bearing would go further but still stick. I then polished a little on the inside of the bearing and it slid on. There was still a little resistance but the bearing seated fully. The next day Joe did the other side and reinstalled his brake drums.
    I am still not sure why both sides would have this problem, but apparently the clearance was not right.

    I need to check the bearing numbers and take some measurements. I'll report back when I find out something. He thought this would just be a simple swap, but his luck has been running bad mechanically the last few projects.

    I have a 55 1/2 ton. I installed a rear end assembly from a V-8 with finned drums-do not remember what year or model it came out of-this was done 30+ years ago. I then installed the front brake assemblies from the same car on my truck. I do not remember if there was an issue with the bearings, but if I remember correctly, it was a fairly easy swap except the spindles are longer but by making the dust caps longer it solved that problem.

    Did you call Jim Turner to discuss?

    This is the complete set of 63 parts parts, backing plate out, he just removed from the 57 he was using it on. The disc set-up got its own bearings etc. and he was trying to just transfer the old stuff. I guess I'll have to try it myself to see if he overlooked anything. I thought mybe there was some change we didn't account for.
    I meant there is a difference between 57 and 63-4 T-cab. Since he changed the bearings, It should fit as all three years (55, 56 and 57) mentioned use the same cone/rollers and cups. Curious, very curious? I'd like to know what you find, please?

    Big difference between the two. You will have to change out both the inner and outer bearings for the 63 stuff to work. IIRC, you will have to use the complete unit (backing plate included) as 63-4 T-cab used the passenger car brake setup.

    started a topic Brakes: Pickup brake swap.

    Pickup brake swap.

    Joe replaced the 63 T cab front brakes on his 57 Transtar with Turner discs. We have started tinkering with the 56 that has been waiting for several years so he was just going to pop all the 63 parts on to the 56. He thought it was going to be a cake walk, but for some reason the outer bearings would not slide all the way on either side. The "57" actually has a 55 chassis. He thought there must be some difference in the spindles, but his book at work showed the same bearing I.D. for both years. Any ideas?
    I was cleaning and checking the carb and did not get my hands directly on the brake parts. BTW The Champion six is running fine again even though I spotted a few things I want to change/adjust.
Working...
