Hi Listers,
This has been on my mind for quite some time;
Why do TR2 through TR4A rear crank seals NOT USE a graphited rope in the
'purpose-made' groove in the scrolled aluminum holder, when Jaguars with the
same type of 'scrolled' crankshaft/seal groove do, as well as some early Ford,
Jeep and other brands of motors?
Did the Triumph engineers decide against it even though the rear aluminum crank
seal parts were already cast?
The special graphited seal rope is still available at Moss (for early Jags) and
other makes of that period..
And I recently read that someone found a rope seal in their TR4 crank seal upon
tear down!.. and he mentions that prior to tear down the rear crank seal leaked
very little.
To me, it looks like the TR motor rear seal was designed to use a rope just
like early Jaguars yet no mention in TR factory manuals.
Been tempted to add the graphited rope.. why not?
Regards,
Carl'63 TR4 since '74
