Mills pin size for suffolk punch mkvii

Hi i was given a suffolk punch mkvii. However the drive clutch for the drum is missing the mills pin.

Does anyone know the size of this. 

Or where i can get one? Part number in the manual is number 24 L-4978


many thanks

The original pin was solid and nominally .25” in diameter. The original genuine ones were just splayed in the centre to retain them in the shaft Most of the aftermarket pattern ones were slightly splayed or slotted down their length.

Try Jon Cruse at the Hailsham Mower Centre for an original or pattern pin , or just buy a roll or spirol pin from a motor factor or agricultural machinery depot.
