Many of Ingersoll's belts are indeed in between the common 1/2 and 5/8's sizes.
FWIW:
^ The C23359 deck drive belt sent by Brian last fall measures .548 after moderate use. Just took it off today, I`ll call that 9/16
bgg.
the OEM belt is NOT KEVLAR.
group,within a few days i will list the RPM increase using the 5/8 belt.
