I went ahead and rebuilt this new blasters bottom end new bearings seals the whole 9...
I get it together and find that i can only shift to 3rd before it bound and got too tight to turn the output shaft sooooo i had to disassemble thinking i missed something and did this 3 times and each time found nothing wrong.
Finally i noticed a couple of metal chips on the bench and right under the shift drum.Come to find out the shift star was able to move 3/4 of a complete circle and caused the binding.Luckily i had one on the shelf that had the shift star welded to the drum slapped it in reassembled and smooth as silk now.
I got to looking at the old drum it seems that woodruff keyway was all broken and split and thats where the metal chips were from i found.
Ill post pics of it ive never seen it happen but i did find i had a bent shifter rod and also swapped that out think it make be an indication to what happened to the shift drum?
