Thank you guys for the info! I can always rely on the forum for good info.What I found out from the shop I bought them from that the crank is definitely an 800 crank,but the cases and crank were sent off to be rebuilt ,,crank was rebuilt to 800 specs ,case was to be checked for true tolerance.was never checked to be an 800 case.The two halves were never mated with crank until I got them. The case has a year 2000 serial # non possibly non ves? (dont know) Looking at my original cases they look good,no ridges or signs of bearing spinning in case, going to use my original case and crank, and send 700 or ? case back. Whats strange is that the crank sat perfectly in the 700 or ? case.Just down for another week ...........Sucks........ Time for a new sled next year for sure!!!!!! I will keep posted in 1 week,
