As of 2022, if your wheel was built prior to 2012, but not more than 40 years ago, run the 42" band/belt system -- item number PW MBT PY.   4 Belts are required when replacing the belt system on a Pacifica GT400 & GT800.  

DON'T FORGET TO ORDER 4 OF THESE WHEN REPLACING THE BELT SYSTEM.  There are four belts per wheel head. 

If your belt is longer than 42" but shorter than 50" you need 42" belts shorter.  If it is longer than 50" you need a 50" belt system part number PW MBT PY50.

 If one is broken and they are all black or green discolored then you should replace all four.  And do so following the link below to see Erin doing it live!
