New Spin Belt Won't Roll on Wheel

I ordered a new spin belt (27001007) for my washer (SAV5600AW). It seems to be too short. I made a "map" of how the belt fed around the pulley and motor before I pulled it off. Then I checked a few other sites for reference on how it feeds through before I put it on, but there’s just not enough slack to roll the belt onto the wheel. I’m a big person, it’s not for lack of strength. If I put the belt on first and then try to force the motor back onto the mounting (and I’m not exaggerating when I say force) I can’t reattach the idle spring without it looking like I’ll stretch it way too far. Any suggestions?

Thank you!

It is not difficult to put on the belt, so either you don’t have it on correctly or more likely, you were sold the wrong belt.
