"TRF'S OWN UPRATED MAGIC CLUTCH KITS FOR TR4A"
The Roadster factory began listing its own uprated clutch kit ten years ago, and
hundreds have been sold to satisfied customers over that time. The Magic Clutch kit
was developed by Dave Hagenbuch from ideas provided by J.K. Jackson of Tallahassee,
Florida and by Dean Houston of British Sportscar Works in Port St. Lucie, Florida.
The new kit was developed to solve long-term clutch problems experienced by many
TR250 and TR6 owners, and as the components of the kit are the same, these kits work
well for TR4A.
Two kits are now available, one with a long-life conventional throw-out bearing and
the other with a high-performance Gunst throw-out bearing. Both kits are now supplied
with precision bronze throw-out sleeves.
Magic Clutch Kits have proven to be very reliable. Several cars owned by TRF
employees are fitted with Magic Clutch Kits.
Our Warranty: We will replace this clutch free of charge if it should fail during the
first eighteen months from invoice date with your choice of either of the other two
available clutch brands, OEM or LUK. To qualify for the extended warranty, you
must replace the additional mechanical components listed below.
Important Note: Always be sure that a new throw-out sleeve will slide easily on the
gearbox front shaft after the bearing is installed. Check the shaft for rough spots and
smear a little of TRF's bear grease on the shaft on which the sleeve slides. If there is
too much friction at this point, the clutch will hang up. Note that instances have
occurred where the clearance between the sleeve and the shaft were too great and the
sleeve cocked on the shaft. The point being made here is that you need to pay particular
attention to this area during reassembly.
