My 1959 5Ta has a belt drive fitted in the primary transmission. According to the PO it was an Alistair Lawrie (of twin Triumph engined sprint fame) kit. The clutch is from a B40 with the drum machined to suit
I noticed a juddering when pulling away in 1st gear so pulled the clutch apart today to fit new cush drive rubbers. I also noticed the belt is slightly damaged so I will need to replace this.
I can barely make out some writing on the belt but have convinced myself that it says
991 Synchroflex AT10 730
I have looked online and have seen some of these belts listed as timing belts. Anyone know if they are one and the same and would handle the high power (haha not) output of the 5Ta https://www.beltingonline.com/at10-synchroflex-timing-belts-30
