Do you think it will be ok?
I'm rebuilding it because of the 3/4 clutch went out. The guy that build it had 7 clutches in the 3/4 pack and only 14 of the yellow springs installed. The transgo kit said to install all 22 springs.
I myself always press the two pieces apart. Once separated you can look at the surface where the feed holes in the drum meet the shaft. If it looks good and not damaged or gauged so to speak, I will reuse the drum. I always lock-tight the two pieces and press the shaft back into the drum. Be careful if you choose to do this. When you press the shaft out you will need to support the drum with a collar of some sort around the spline area. This will keep you from flexing the drum and weakening it or even cracking it when taking it apart. On reassembly make sure to the same thing to support the drum so that you do not damage the drum on reassembly. I usually use a large deep-well impact socket for this. While you have the drum apart clean this area where the lock-tight will be used so that it does it job. Also these shafts should never press out very easy or in easy. If so you could have potential problem. I probably would not use that drum because of the area that appears to be damaged, there is a seal for lube that rides there. That would be your call. Vince
replace that sucker. I try to always press out the shaft from the drum, powdered metal builds up inside there and its tough to get it out. Plus its easier to inspect for cracks and defects.
