This is, I truly hope, the final update which you deserve after all your =
advice.
=20
Cross yr fingers and toes but I think it's fixed. Not 100% sure what was =
wrong but it was like this:-=20
1) Removed gearbox.=20
2) Inspected release bearing. Still had about 2mm of carbon but ordered =
new one anyhow.=20
3) Removed clutch. Looked good as new, which it is/was virtually. Had my =
mate at local garage look too. He said it was fine. Had I had it in the =
right way round? Yes.=20
4) As clutch passed visual and road test, slippage was now very likely =
to be within the driving half of the overdrive as I had +/- 520psi on my =
gauge. (Dave=E2=80=99s gauge said 550psi)
5) No way was I was taking that half of the OD apart. Arranged to be up =
at ODSpares by 08:00 for Dave Twigger to dig into it.
6) He said there was some wear in both clutches, "cone" and =
"uni-directional". He'd replaced them both as silly not to once he'd got =
that far. He said that he wasn't sure if the wear was sufficient to =
cause the problem, but that it could. Not v. satisfactory. However, =
he=E2=80=99s the expert.=20
7) Reassembled it all.=20
8) So far, on two test runs, it's performed =
perfectly...=E2=80=A6=E2=80=A6..Frankly, I don't know where I am with =
the ****** thing. Not sure I trust it.....rather dispiriting actually. =
If it happens again, the gearbox can go in the attic and I'll look for a =
Toyota 5 speed!=20
Thanks again,
Simon

Simon-it sound to me that your slippage is in your driving clutch. If =
OD is in direct and the 8 springs doing their job, the engine clutch is =
suspect if slipping occurs. Healeys are known for that issue from the =
early days of oil on the disc. In rallies they sprayed the clutch with =
brake cleaner to stop the slipping.
Then too I remember that you had issues with your pressure plate when =
replaced...your model had 3 different PPs depending on the year and =
upgrade and the absolute correct one must be used with the correct =
gearbox.
=20
Slipping when it gets hot (or saturated) in direct drive (or in OD for =
that matter) indicates engine clutch issues. Hank

Subject: [Healeys] Overdrive pressure or clutch slip Step 3=20
Just when you thought it was all over......
So, thanks for all the replies and advice so far. I've only been able to =
get back to the car in the last few days. Better weather and negotiating =
various domestic hurdles (usual stuff). Mindful of specific advice:- 1) =
I swapped the relay for a new one left over from the last bout. The one =
in the car passed the tests but it could have been marginal I suppose. =
2) I swapped the solenoid for a new one left over from the last bout. =
Ditto above. 3) I adjusted the Throttle Switch. God, that's a wretched =
thing. 4) Checked oil, electrics etcetc. 5) Pressure good at +/- 520psi =
6) OD going in & out per usual tests ie when sitting in the garage =
Etcetc Took the car out for a longer trip today. Performed very well for =
about 10 miles then the slippage(?) started again. Especially on hills. =
Removed the OD's fuse which, I reckon, puts the OD out of the game. =
Symptoms continued. Now.....I know and I've experienced low OD pressure. =
All's well until oil warms up and pressure drops. But, now I've =
supposedly taken the OD out of the equation, I'm asking myself, "ODs are =
effected by their oil's temperature but the flywheel/clutch connection =
is friction. So, it either slips or it doesn't ie regardless of =
temperature." Is that right??? Despite that question/worry of mine, I am =
leaning very much towards clutch slip as opposed to OD, which is pretty =
new don't forget. The slip is pretty drastic and seems to have worsened =
noticeably. I'm reluctant to take the box out until I've ruled out a few =
alternatives. If there are any! Besides an issue at the clutch plate to =
flywheel connection, is there anything else that can cause this? Or are =
there other areas yet to be explored. I really need to get this thing =
fixed as am hoping to take it over to Ireland in July. Simon =
