The DeWalt 733 and 735 are totally different designs. The 733 and 734 are very similar, differing in blade sharpenability. There might be some shared components between the 733 and 735, but I don't know because I've never been inside a 735. While I have repaired a 733 more than once for broken sprockets, worn bushings and stretched chains, I've never heard of those problems with the 735. Is there a chance of mistaken identity somewhere in this thread?
