Which Torsional Coupling?

[marchy]

I have QSC8.3 600 HO and ZF 286A. Hrs 1,600 in recreational use. Small rubber bits being ejected.
Which coupler is the right replacement one?
Is the “Centa CF-R Torsional Coupling ZF 285 286 A/IV” the only choice?

Torsional Coupling failing

There are 3 types that were used.. Centa CF-DS, Vukardan E, and the Centa CFR…….I have seen all 3 of them fail at relatively low hours. With “bits” coming out, most likely the CF-DS 1st, the CFR 2nd.. We usually stock all 3 types.. You need to take it apart for a good peek to ID it..
