[Healeys] Seeking List Wisdom

[Michael Salter]

To positively determine if the problem lies with the operating system or the unit itself it's best to run it with the gearbox cover off and operate the checking lever.

Hey Bob,
Doesn't sound like the pump - 400 psi is good, but this can be removed/resealed in situ.
Your clue would be that it might engage at high roadspeed but not at low.

I had a solenoid that was 'weak' and behaved like yours.  It functioned, but resistance was high and pull force was low.
It might throw but have marginal force to open the ball valve when under pressure.

Best way to isolate this is to check resistance or current of the solenoid.

Good Luck!

I've had an intermittent issue with my BJ8 O/D. It doesn't engage
reliably, but does maybe 1 out of 10 attempts. I think I've ruled out
electrical issues, as the solenoid activates reliably. I checked the
hydraulic pressure, it's just under 400 PSI. I know that's low per the
shop manual (470-490), but it has worked reliably for years and had the
same pressure after an overhaul.

Q1: Any ideas why it has stopped engaging after years and thousands of
miles?

Q2: If it's the pump, can these be changed out in situ?

TIA,
Bob
