TR2 Overdrive Switch Position ?


Recommended Posts

Hi,

could I get some thoughts on the attached TR2 dash photo please.

There are holes in the metal dash (under my A & B stickers) and the holes have been trimmed over. I want to fit an overdrive switch with a separate neon indicator fairly soon, but leaving a thought for a heater switch at some point in the future.

Bill P's books show a variety of combinations and layouts in this area of the dash and I was looking for some standard positions to follow.

Many Thanks

Bob

A is where the heater rheostat goes, the overdrive switch is at the same height & is to the right of A now "B" below:1216734632_DashRHside.thumb.jpg.8efd6b0f3212be0659b8507695e4c771.jpg.77b1b51570db3ca27609b9ce48e99a23.jpg

You want the switch where your fingers can reach it without having to take your hand from the steering wheel.

That's probably B on Bob's mock-up, but your original B might be suitable (and would avoid the need to drill a further hole).

On my 3A, the egg-shaped overdrive switch is at your original B position and it falls easily to my fingers without moving my hand from the wheel. Depends what you priority is: originality or convenient use (if Bob's B position is not so convenient).

If you are going to instal an 'overdrive on' indicator, I do not think this was ever standard. I installed one and used a new dash bulb mount with a green lens and a green LED. Works well. Picture below if it helps.

Just for the record, I find the O/D switch in "my" position is easily flicked up or down without taking hands off wheel. Of course TR2's actualy had a push pull switch in that position ( like the panel light switch)

I agree with Bob.  When I rebuilt my car and converted it from LHD to RHD I acquired a S/H dashboard which was ready drilled for overdrive in the position Bob recommends. Initially I thought about moving the switch but I use one of the original egg style switches and it falls beautifully to hand.

I thought that too Bob so purchased the push-pull switch. Turns out only very early TR2's used that one, later ones (mines Sept '55) were eggshaped switch according to Bill P's books.

Same dash hole though I think.

I take your point Ian C about switching the OD in/out with the fingertips, I personally prefer the stalk type switch (as fitted to 4A & later cars) so the eggshape switch in a way is the closest to this as its a lever action not a pull action which is near impossible with one finger!

Miles: yes your OD indicator looks good. A neon indicator (or LED) is planned for mine, but it will be mounted alongside the switch since as I already have a spare hole there.

Thanks All

Bob

Precisely the layout in the link I gave from the Triumph Laycock installation manual.

Thanks again all, photos very clear & I think that has answered the question on switch positions, it appears my dash was probably swapped as there is no hole in the OD position and it was an OD car from the factory.

However, I'm now investigating the egg shaped switch for the OD which I read is not only correct for the late TR2 (from TS6266) but also allows single-finger use.

I found a reference to this in Bill P's book 'TR2, 3 & 3A in Detail" on P186 and Bill refers to the egg shape switch as the "Drum-Type overdrive flick switch" which I assume is the one. This was May '55 so some months before TR2 production ending.

Regards

Bob
