James----When their is a difference in proceedure as to how a certain
part is to be used, I sometimes go to a third party who has more
experience than I. And so it is now, in regard to this bushing. Here is
what I was told by the tech guy (Dave), at TRF:
The TR four cylinder engine, and the early
six had a long pilot bushing (1" x 1/2" x 1" long, which was inserted
into the end of the (longer) crank.
The later six, from around 1970 on, had the
shorter crank end, and used a bushing that was only 1/2" long. The
actual OD was .998 and the ID was .500. This bushing is placed into the
flywheel. By virtue of the .002 difference between the bushing OD and
the flywheel counterbore, it will "float" in place. (It cannot
accidently come out, due to the lip on the flywheel)
The bushing is Oilite and this is pre-lubed by
the maker.
Other greases can be used with this bushing,
when there is convenient to do so, and is suggsted that this be done.
Other info that I dug up is in the Bentley manual. Instruction 12.21.45
showing that this bushing is "to float in the flywheel".
So this would be a good time to re-request that listers seeking advice
to please include the year of their TR somewhere in their post. And the
area where the car is driven can at times be helpful. This could reduce
the possibility of different answers, given the subtleties of the TR
six.

Pilot Bushings
Actually, these bushings/bearings are "olite," that is, "sintered," or
porous bronze. Unless stated that they are pre-soaked, they must be set
in 30W oil for about 24 hours, to insure proper functioning. Do not use
any solid lube, such as bearing or lithium-type grease, in that this
will plug the pores in the bushing, which will not allow the proper
lubrication over the long run. Remember, once in the crank, they will
never again be oiled.
They are to be a light press fit in the butt of the crank, although I've
seen many that after many years seem to have worked their way loose, to
no particular detriment...........Cheers
