Simon,
=20
I have spent far too much time taking the seat runners apart repairing =
the
threads. The original is 1/4" x 28 and any replacement fasteners needs =
to be
ground down so the head doesn't interfere with slide mechanism. In my
opinion it is critical to use the Tee Nuts and the 14ga stiffener. These
help strengthen the floor boards and secure the seat. Healeys don't have
much crash protection as it is but it will enhance safety if the seat
doesn't come loose in an accident.
=20
Your seat runners may have been altered to a point where they can't be
restored. My solution was to cut off the threaded portion from the =
bottom
and then drill and tap the remaining flat head welded to the track to =
1/4" x
28. I ground down a 1/4" grade 5 bolt and threaded through the tapped =
hole
and put epoxy under the head. If I had to do this again I would buy new
tracks from AH Spares. Their quality is excellent and they cost about =
$65.
AH Spares has the Tee Nuts as well.
=20
The seat track assembly is confusing but here is the original sequence =
from
the bottom up:
=20
Tee Nut
Spring Washer
Flat Washer
Floor Board
Black Felt Paper
Jute
14 ga Metal Stiffener
Wood Packing
Seat Track
=20
Good luck ... Harold

Subject: [Healeys] Seat Runners
First of all, thank you for the responses. All very helpful. Now I know
exactly where I should be. Should be!=20
However, some ham-fisted cretin has been in there before me. I find that =
the
slides are held down to the floor by bolts whose shank size is 3/8=94. =
They=92ve
each had two of their flats ground down and they pass through 3/8=94 =
holes in
the bottom half of the slides and thence through the floor to the =
outside.=20
I think that it=92ll be too much trouble to replace them but, just in =
case, :-
What is the outside diameter of the so-called tube nut or t-nuts which
should be coming up from below?
And what size are the bolts which come down from the slides/runners, =
through
the floor and into the tube nuts? =BC=94 unf 28tpi at a wild guess? Or =
bigger?
See attached.
And, finally, is there another name for these =93tube nuts=94 by which =
they
might be found and bought at a sensible price? From their prices over =
here,
they seem to be made of platinum.
Thanks,
Simon
