Hello All, recommissioning my 01 310 with 350 Horizon/Vdrives, after 4 years of inactivity. Have motors started, but struggling with keeping the serpentine on both motors! The pulleys did have rust and I have tried to clean them as much as possible while attached to motor. All turning parts are turning freely. Have checked alignment from raw water pump to crank pulley. That was off a little on one motor. Removed pump. Cleaned all mounting holes and that is better, but belt still wants to climb off of the rw pump pulley. Pulleys are perfectly aligned now. The other motor throws it almost instantly. I thought serpentines were a little more able to compensate for slight misalignment. Any thoughts would be appreciated.
