Cat SX3 rear belt installation issue

[mlee]

Hi All,

I am having problems of installing the rear belt.. After installed the rear belt, I can hear a "knocking" sound come out from the pulley located in the mid section. I have tried reassembled 3 times and still having the same issue. The "knocking" sound disappeared when I take off the rear belt. Anyone of you have this issue or this is normal? Please help.

Thanks,
Mark
