Saving Old Seagulls

Are the prop shafts same diameter for fortys and centuries?

Need a thrust washer for a WSPC and can grab one off a spare 40. But I don’t have them in the same place to compare beforehand, so want to check before I make the trip to bring the 40 back.

Thanks!

All of the classic prop shafts are the same diameter, 1/2" & there are 3 different thickness hardened steel thrust washers so that adjustments can be made to ensure the crown wheel & pinion teeth mesh quietly & properly!

Excellent, thanks Charles!
