 That's another weak point that I have noticed with all Spitfire related 
Triumphs.
 The vertical link at the front lower trunnion either:
 
 bend (with good luck): http://personal.inet.fi/koti/jtabell/link2.jpg
 or
 break (with not so good luck): http://personal.inet.fi/koti/jtabell/LINK1.JPG
 
 Does anyone have any cure for that?

As it turns out, upon further investigation the left rotor had a 120 degree 
piece missing. It looks like it broke first, causing the wheel to lock which 
overstressed the lower trunnion. The trunnion was free to turn so I don't 
think it broke first.
