Yes they recommended the 6PK-1025 which has one rib less instead of the standard Gates belt which I have of 7PK-1025 which is silentish..
If it starts I just hold a cap full of Cellulose thinners near the belt whilst it's running and it cures it instantly for a long time.
I learnt the trick from a very old experienced Engineering colleague of mine except we would use CTC which is no longer readily available.
