Unless there is a reason not to; this sounds like a prime candidate for
the VTR pages and perhaps magazine/newsletters.

Hey Jeff,
The TRF Magic clutch is a combinatoin of parts from various
other cars. Below is an email describing the clutch.

Hi Folks,
A few weeks ago, I put a message on the list asking for
recommendations
for
good machine shops in the San Jose, CA area and asking if anyone
knew the
specifics about the "Magic Clutch" that TRF sells (since they
are so
circumspect about it and charge a small fortune for it, along
with
requiring you to completely replace all the parts internal to
the
bellhousing if you want it guaranteed). Anyway, I got some good
messages
steering me to good machine shops, <thank you !!> and some
messages
asking
me to tell them if I found out the specifics RE:the clutch.
However, no
messages with anything specific about TRFs clutch kit. I found
this
really
strange - TR people are usually inquisitive by nature so I
thought
somebody
surely would have taken the time to "reverse engineer" the kit
contents -
especially since TRF readily admits that the idea was not their
own in
the
first place, but instead came from two gentlemen in Florida.
Not being
easily discouraged, and having free lunch hours to make long
distance
calls
and burn the internet links, I decided to find out the answer.
What
follows is the compiled data from my study - I do not have any
interests
in
any of the companies listed below.
1. Clutch Release Bearing (or Throwout Bearing): The bearing to
use is
the
throwout bearing for a 1975-1986 Toyota Landcruiser. This
bearing has a
Beck-Arnley/Worldparts part number of 062-0898. Other part
numbers it is
listed under are "RCT52S", "RB-0203", and "046", but you can
just ask for
a
1975-86 Landcruiser Throwout bearing and you will get the right
part. It
is a larger OD than the stock TR-6 T/O bearing, but the ID is
the same,
so
it presses onto the stock TR-6 carrier/sleeve. Shop around for
the best
price - I was quoted from a low of $40 to a high of $80 for the
exact
same bearing.
2. Clutch Pressure Plate: The Pressure Plate to use is the
SACHS
pressure
plate for a 1979-1991 Saab 900 w/non-turbo 2 liter engine. This
has a
Sachs part number of SC436, and a Saab/Metrix Parts part number
of
87-28-123. When you buy this make sure you are getting a Sachs
part -
Borg&Beck and Sachs were used interchangably on the 900 series
and the
Saab
part number does not distinguish between the two brands. If you
get a
Borg&Beck you are getting the same part that you (most likely)
just took
off your TR-6. The best price I found was from "The Parts Guy"
(phone
800-874-1850 - P/N SC436, $49.95 + shipping).
3. Clutch Friction Disk: There is no Sachs friction disk for a
TR - the
Saab has a different input shaft. Use any brand you want - as
long as
its
not Q-H ( Q-H will probably work - they are just really poor on
quality
control).
Additional hints I gathered:
1. Hone or machine an addition .010-.020 of clearance off the
inner bore
of the throwout bearing sleeve. Apparently at higher
temperatures, it
has
a tendency to stick. Also install it with some high-temp
grease.
2. Drill a 5/16" hole at a 90 degree angle to the retaining pin
(offset
from the pin - you don't want to drill through it) through the
fork and
rod, and istall a grade 8 bolt and nut as additional insurance
from the
pin breaking.
Well that's it. Hope I didn't offend anybody - I was wondering
if this
info was like a Masonic oath or something. Many thanks to the
folks at
Beck-Arnley/Worldparts, Metrix South, The Parts Guy, Midway
Industries
(Centerforce Clutches), Sachs-Boge of America, Saab, Toyota,
Economy
Imports, Olympic Imports, Auto Parts Club, and several folks who
wished
to
remain anonymous - I could not have done it without your help,
parts
books,
knowledge, and infinite patience.
Have at it !!
