On original Stanpart trunnions there is a shouldered step at the bottom on
one of the trunnions (I can't remember which offhand), but recently
manufactured trunnions seem to have lost this in the machining process,
despite being made using the same tooling. In fact, the most recently
produced trunnions are absolute c**p! The metal disk in the bottom isn't
properly peened over - they invariably leak dreadfully and I have seen some
of the disks drop out with no pressure, just gravity! Before fitting them to
the car, try filling them with EP90 and let them stand for a few hours - if
they leak then you will need to have the disks fixed in place by soldering.
There is such a high failure rate on the new trunnions that I wouldn't
consider fitting any without at least checking - a friend who restores
Triumphs professionally has shown me so many of these in recent months that
I take the problem very seriously,
Cheers,
Bill.
