[Healeys] Noise on engaging clutch

Tue Aug 4 13:20:31 MDT 2026

Yes, I’ve heard that. I looked into my files and that bearing is about 18 months old. Just long enough for a dud to play up….?

I recall there was a bad batch of the graphite release 'bearings.' If one was badly chipped it may cause such symptoms.

I'm assuming that this is the standard B&B spring clutch and not the later diaphragm clutch found in the BJ7-8.

When you did the install 18 mo. ago did you by any chance hang up on the PP upon offering up the unit to the pilot beating. In other words, did  you have difficulty moving the trans exactly centered forward and home without any resistance? Hitting something?

The center yoke of the pressure plate is suspended and if you hit one of the hangers it can later manifest into a misalignment and noise at the TO bearing. Feeling it in the pedal is a clue. If it was a later diaphragm clutch and has a broken finger you definitely get pedal vibration.

One other "test"... upon driving; is the noise (vibration) better or worse when in OD or direct?

Probably should not drive it much until issue is found but I'm afraid to say it may involve R & R of the unit.Hank

Simon - 

Your email is a little confusing - a couple quick questions:

1) Does the clutch make the noise while your foot is on the clutch?  While your foot is on the clutch does it do it if the car is in gear?, or not in gear, or both?

2) are there some pinging or slapping noises one you have full let the clutch out, or does it only make noise when your are shifting?

Hi,

I need advice regarding a new issue pertaining to my clutch/gearbox. At least that is my understanding. By “clutch/gearbox”, I include master and slave cylinders….

Car is UK RHD A-H3000 MkII BT7.

Has marginally lightened flywheel.

Centre shift.

Clutch plate is about 18 months old. Not gone long distance nor been thrashed around.

Noise is not related to engine speed.

I did some tests in my backyard……

I made a few notes:-

Reverse out into backyard…..no problems.

Back and forward in first and reverse about 5 times then the noise starts in both gears.

It is a harsh rubbing/grating noise, accompanied by a vibration which I can feel in clutch foot. I get impression that it’s down low on rhs.

Can feel vibration in my clutch foot when the noise is happening.

Noise happens as I lift clutch foot to engage reverse or first. (Didn’t try 2nd)

Noise stops once I lift foot all the way and engage gear whereupon car drives normally ie noise only happens when in process of engaging gear.

There is no noise or vibration when car is in neutral.

Noise does not occur every time. Most times.

Now, my belief is that this may be something to do with the carbon “release bearing”. Maybe not wear because it’s pretty new but maybe because it’s not engaging fully or it’s not aligned right. I’m thinking about slave cylinder or master cylinder issues but they’re pretty new as well. Can’t speak for the flexible hose going to slave as I’ve had so much, basically overdrive, issues in that area that I can’t recall the minor parts.

I absolutely dread having to take the gearbox out AGAIN and am hopeful that it won’t be necessary.

Any ideas??

Yours hopefully, Simon
