I have the rear-engine 381450HBVE and had to replace the drive belt #4-7117 that connects the engine to the hydro-drive. After using it for five minutes it melted off again. I think the belt went on with just the right amount of resistance, I had to walk it around by hand after it was about 1/3 the way around the drive pulley. The idler pulley part #2-3954 was also replaced because the top was chipped so I double-checked the spring tension and it felt good. I verified clearance and thought it was good. Alignment looks good.
The only thing I can think of is that the transmission itself is resisting at engine speed, but without the belt on I can easily turn the hydro drive's pulley by hand.
Any ideas?
