battery cutoff switch removal

battery cutoff switch removal

(OP)
I installed a battery cutoff several decades ago. thus I don't recall how it did it.
I now want to remove it but can't figure out how.


I just noticed a slight raised center section, that might have been a press in cover with a screw holding the knob to the shaft.
the question is, any suggestions on how to pull that center piece (hoping it is removable)


OR

If anyone is familair with a Lucas SBB103 switch, how does the knob come off

RE: battery cutoff switch removal

Is there a setscrew binding the knob to the shaft? My Austin Healey has a shutoff switch in the trunk(boot) but I never took the switch out or apart.

there is no radial screw access either on the black plastic shaft nor knob outer diameter. even the metal drive shaft for the mechanism is full round with no "keying" ridge/flat.

In my gut memory, I recall thinking this will never come off again when I installed it.

while I want it out (It was erractic during the recent getting the car driveable again work), I don't want to mangle it up.

I am planning on hot gluing a bar on that center emblem and MAYBE it will pull off and expose an axial holding screw.

RE: battery cutoff switch removal

Can't get a pick or something under it?

The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: battery cutoff switch removal

(OP)
my attempts to get a micro flat blade screw driver have only made gouges. I really don't see any division line, it is just a hope as a possible means for the knob to be retained.

RE: battery cutoff switch removal

My recollection from working on the odd classic car is that the knob is a push-fit onto the shaft. I can't remember if it is a D or spline. The visible portion is cylindrical, but the hidden portion isn't. If you glued it years ago then expect it to shatter if you apply force. If you didn't glue it then expect it to shatter anyway. Such is life with old British cars.

RE: battery cutoff switch removal

So, how do you get the knob off it :)

other discriptions of the current offering Berkshire linked, refer to it as a "permanent" knob and the mounting instructions are for a larger hole to hide the mechanism and the flange (and knob) be external

RE: battery cutoff switch removal

(OP)
correct...
My mechanical aptitude has declined a lot in the last few years.

It finally dawned on me, if I couldn’t remove the knob from the switch, then remove the switch from the knob!
Then the hardest thing was getting my "mirror image" dexterity

RE: battery cutoff switch removal

Brilliant!

RE: battery cutoff switch removal

Are you telling us a Lucas switch worked for "decades"? Which position was it stuck in; dim flicker or off?

LOL... when I installed the switch, I left the original ground strap hanging and a wrench to change back under the hood. shortly after, the car was "parked" for those decades and just recently during the work to get it running again was it found in the dim mode, so back to the original strap.

flat blade screw driver

I don't mean to derail this thread, but how many others here call it, or have heard it called a "flat blade" screwdriver?

I personally have always called it that, but lately I've come across a number of people that say "flat head" screwdriver.

I suppose either is correct, but I can't bring myself to say "flat head screwdriver".

RE: battery cutoff switch removal

(OP)
would that be a "flat head screw" driver

RE: battery cutoff switch removal

"flat head screw" says nothing about the drive needed.
It is just a screw style, not a diver type.
It is a flat blade screw driver, or a I guess a driver for straight slotted screws.

RE: battery cutoff switch removal

I was going to say, a flat head screw can be anything with just that; a flat head.

I have always referred the type of screw driven by a "flat blade" screwdriver as a slotted screw.

Consequently, I've heard the term "slotted head" screwdriver as well. Which makes sense to me.

RE: battery cutoff switch removal

For years it was called a "Flat" or a flat blade screwdriver in the trade in my area.
Flat head screw; With a slot, a Phillips or a Robertson socket.

Flat-blade screwdriver, slot-head screw.

Or occasionally, slot-head nail. 😛

disappointed Scotty...I was expecting you say they were turnscrews.

Or is turnscrew what gunsmiths call a screw driver so they can charge big bucks

RE: battery cutoff switch removal

A turnscrew? That's a new one on me. smile

Apart from the slightly amusing entries in Merriam-Webster (a device for turning screws) and Wiktionary (a screwdriver), it does seem to be a term used solely by the shooting fraternity. I guess it is a very old word.

RE: battery cutoff switch removal

It is also a term of endearment for prison guards.
