belt too long after repair???

I have a murray lawn tractor 38618X92E.after my son repaired it the belt seems to be a few inches too long.The belt # 12-6509 which I have crossed to be the same as 37x63. 1st he replaced the engine w/ a used one.Which he says he put back in the same holes.He transferred the original motor pulley to the new one.He said that he did do some mowing after that.Then he pulled the deck & replaced both blade spindle bearings.When he put it back together the belt just comes up too long?we found a part break down online.Everything looks right.I ve looked at all the brackets cant spot anything out of place.All the pulleys on the deck are the original.I d really appreciate any help!thanks

Sounds like the belt isn't routed properly around all the deck pulleys.I always draw a schematic of the belt routing before removing the old one if there's no schematic already on the deck. Of course if the belt breaks w/o a schematic that's a whole new can of worms!!

Well if all the pulleys and routing is the same as before, then I would still suspect the belt.
New bearings?
Is there a manual PTO for the deck? Could be an adjustment...
Something a bit tighter or even binding or stretched belt...

Belt could still be worn or glazed, pulleys wore out....
really hard to just guess for issues in this case without being able to put some hands on...sorry

Is the tensioner pulley traveling the full length of motion? Can you grab the pulley and move it further, tightening the belt? It could be that a blade brake arm is sticking and keeping the tensioner arm from moving fully.
