It turns out there are two clutch types available for the MGB GT…
Here’s the summary…
HK9679 (Heavier Duty Version):
Heavy Duty Fits all 63-80 MGB’s & MGB GT’s.
The HK9679 has smaller driven plate friction linings as the larger linings were prone to judder.
The reference numbers of this kit are…
– HE3517 cover assembly
– HB8752 driven plate.
– HD9108 roller release bearing
Includes the pressure plate, disc, and release bearing. It will fit any 1963 – 1980 MGB or MGB GT. These clutches are a little bit cheaper than HK9679 clutches.
The HD may be referring to Heavy Duty, as the standard version of the kit; HK9694 which has a different cover, drive plate and the old type carbon release bearing (HD3317).
The HK9694 reference numbers are…
– HE3331 cover assembly.
– HE9711 driven plate.
– HD3317 carbon release bearingThis is the second time in five years that the carbon thrust bearing has shattered, and I wonder if the judder mentioned above has anythng to do with it. The first I suffered this issue was soon after I purchased the car, (it hadn’t been driven much prior to my purchase), and then again the other day after not being driven for a year. Whilst I can’t tangiblhy prove this, I also wonder if the standard carbon bearings don’t like being laid up, and maybe seize up if not driven regularly. Please note: I don’t know what make the original (shattered) clutch was, so the picture of the Borg & Beck clutch is for reference only.
A few days after returning home, back luck struck, whereby the carbon clutch bearing had shattered/disintegrated. I don’t know what caused this, so I can only put it down to being laid up for a year and something seizing up.
So, using the opportunity while the local garagae, (Church Garage on Stockbridge Road in Winchester), had the engine out, I managed to get the day off, and went there armed with paintbrush in hand…
Before… flaky red paint.. just a mess really!
After… Racing Green… It’s a complete transformation… loving it! 🙂
Engine bay… stay tuned!
