VJ 1614 steel belt snapped (also need manual please)

Hi Everyone,

Friday during a print my steel belt snapped. The printer is going on 4 years now and has never had a single part other than wipers and sponges replaced. Mutoh techs say that it is very uncommon for a belt to snap after it's first week in production. I don't see anything that could have caused the break, nothing changed in it's tension other than normal stretching of the steel over 4 years. The break in the belt is a clean break (not sure if that's common or not.) Anyway - I ordered a new belt and it came already (no thanks to Mutoh, +1 for GEI, -1 for fellers)

I want to get this belt in and get running asap, I just wanted to hop on here with all you Mutoh users to see i I should be aware or concerned of anything first. The last thing I want is the new belt to break. I could also use a user's manual, the one that would show how to replace this belt if there is one. I'm pretty sure I know what to do, but it never hurts to read up as well.

Thanks guys, looking forward to your responses!
