AVR G-Force Bedtiller . The PTO shaft has got damaged at the machine end. We only need the slip clutch assembly. They will not supply. Had to buy the WHOLE shaft at a cost from AVR of nearly £2.5 K . Managed to find a cheaper supplier but still £1850 . It is an inch and three quarter shaft with 20 teeth . Only used by AVR . I could have bought cheaper but only if I bought 6 of them. Robbery
