1969 Triumph Daytona T100R Fork Gaiter Replacement

[@nealastle1607]

I have a 1967 Triumph Daytona with these forks and the 1968 8" twin leading shoe backplate. Superb video, which shows a much simpler way of changing the fork gaiters.

Aren't these bikes all metric?

Hi Rob, no metric threads on any Triumphs of this era, most fine threads are UNF and course threads are UNC, however some of the engine components have BSF and BSCY threads. Triumph changed some thread forms from BSF/BSCY to UNF/UNC around 1967 and have a mix of the two, BSA did the same although a year or two later, but no metric threads. The Triumph was sold to me as a 1969 bike, however when l got the dating certificate from the Triumph owners club it states the bike was manufactured in December 1968, so the American title that came with the bike states manufactured in 1969, that should really say it was shipped out of the UK in 69 not manufactured. Regards Brian.

@@TheCADengineer To be frank, when I saw the twin leading shoe backplate, and operating mechanism, I thought that it was from 1968. I believe that they only made this style of backplate and operating mechanism for 1968. From 1969 onwards, the front brake cable entered from behind to operate the twin leading shoes. As an aside I have a 1967 Triumph Daytona which was registered in 1969. I never understood that until I got my copy of the dating certificate. Turned out it went to a lucky person in Cyprus first then later returned to the UK in 1969

Hi, That style of 8" twin leading shoe with the vertical pull was fitted to the T100's up to 1973, however there is the same style front brake fitted with a horizontal pull and the only difference is the cast lug for the outer cable and the lever on the second pivot so the cable comes out horizontal. The vertical pull front brake is also exactly the same front brake on the BSA A65's of the same year. I have seen that horizontal pull style drum a couple of times before but can't recall what bike they were fitted to. My T100 went to North América and was imported back to the UK in 2022, it was sold to me as a 1969 as that was what was suggested by the serial/frame number, however when I got the dating cert from The Triumph Owners Club so I could apply for an age related number plate the info said that the bike went out of the Meriden factory between Christmas and New Year 1968.
