Didn't need a new project...but I got one!

(1/3) > >>

SumpMagnet:
Been struggling off and on to find time to finish my 750F2 ..... and doing a load of stuff to my daily ride....and then, well..I got made an offer I couldn't refuse.

this is basivcally a family heirloom. My father bought it some 45 years ago, slowly brought it back to standard, then it got mothballed for a bit, partially pulled apart, then sort of left. He was busy renovating other folks bikes, and she got a little neglected. I was asked to give it a new home....and had to say yes.
Comes with some issues, needs cosmetics and most seriously...the distributor had been popping out, which was traced to ovalling of the crankcase opening where it sits. I have a spare set of cases, and a 500 head and barrel ( +20...but needs a rebore) Plus an assortment of other bits and pieces. 2 sets of exhausts, electrical goodies....3 boxes full!

So now I got that to play with as well!

For the record, she's a 1959 Triumph 3TA

The 500 top end is a straight swap, which is why I think Dad bought it. Gives a useful increase in performance.

Paint has a number of issues, but from a distance away...it looks pretty. And it's complete. Nearly.

That looks a nice bike - I'm sure you'll enjoy the project rebuild

Bryanj:
Timing side mains are not good, primary chain tensioner same, worth more as a stock 350 than with 500 top end.
I would repair original case rather than change.
Slow but nice handling, brakes are yes

SumpMagnet:
I rode it for a few hundred miles around Wales quite a few years back. Brakes are.... no. 7" SLS. Stop faster if you put your feet down!

Primary chain tensioner is a pretty crude device, but the bottom end had all new bearings and bushings not that many miles ago. The old man is the Triumph specialist, but as I recall, it's roller bearing one side, and plain bushing the other. Hand ream and much engineers blue went into the thing. It's a foreign world to me! Full of strange bolt sizes and spanners

 If anyone knows where I could get the case repaired, I would be interested to know. It's the original motor with corect matching numbers, so even if I swap the cases to use it...I was planning on getting the originals repaired. I assume it''s a case of machining it out and putting a sleeve in, or welding up and recutting.

Bryanj:
Yes its a case of machining and sleeving but you would need to strip the case out to do it.
You would need to find an old school engineering shop to do it, i can  think of a couple up here in gloucester(ish) but dont know London.
Rebore is relatively easy after you found piston kits
