I'm actually going to try for, wait for it...

Alfa 155 gauges!

The 155 dash has everything you could want...

(and before someone says; 'you can't do that- the gauges don't separate'- Its true they don't, but it doesn't mean it isn't possible...

It's got the oil temp and pressure. Sounds like a good project. Would you have them in separate dials like the VDO dials.

I was thinking of an ammeter but the risk of an electrical fire put me off.

'an electrical fire'!

Ha! don't let that put you off! I'm not sure I've seen an ammeter on a car...? I saw one on a fire engine once...

You'd get a period Veglia voltmeter from an Alfa; but that's not as important I don't think- by the time it tells you anything; it's too late isn't it!?


Yeah-I'm hoping for separate dials; in the ashtray in fact, so I can retract them for the standard look..!

Not sure they'll fit though... looking into it now.

see my other 'instruments' thread...

I do like the look of the veglia gauges. Some of the ones I've seen on ebay look like aviation gauges with the aviation font. Really coolio.


Like these?

Yes. I like the look of that gauge. Already getting bored of the VDO gauges I haven't even used yet lol!

Anymore detail on the sender. I take it it has got the 1.00mm pitch on the thread.

Luvvley!

The ammeter.. it's a gauge thing: to fit as many gauges as possible. Only thing I don't fancy a 60amp wire coming in to the cabin. Maybe drop the ammeter idea.

QUOTE(Desperado @ 28th May 2017 12:06) *
I've just made adapters for mine, the tapped hole in the head [above the thermostat] is M10x1.25 [parallel thread.Although the plug that came out is tapered]

M10x1.5 is a standard M10 thread
M10x1.25 and M10x1.0 is Metric Fine

Photo of the adapter attached

[attachment=17273:oilpress...radapter.jpg]


I cannot find any adapters on the tinternet that have the 1.25mm thread for the plug hole so will get my local engineering firm to make one up.

The sender came from Greece....I havent had time to power it all up yet so I dont know if that sender will work. I expect it will but they're a bit of an odd type. I sent a picture of the gauge to the supplier and they confirmed that the sender was correct. Yes it is m10x1.0 thread. I'll look back through my purchase history and find the supplier.... Original on the Fiat 124 coupe.

a lot of this stuff seems to be in Greece, actually Desperado.

genuine FIAT / Alfa items.

I expect it will work...

I used to go to Greece each year and the second thing I noticed after the women were the number of Alfas there. In the UK it's German cars that are everywhere. Saw my first QV Giulia in Greece. Well nice it looked.

right!

more gauge-sender fun...

I got hold of an equivalent 155 oil temperature sender and lined it up to the blanking plugs on oil filter mount. (as I don't have a 155 sump with threaded-hole in the 'wing' top)

following on from Ganz's adventures; I thought the M18 x 1.5 male to M10x 1.0 female adaptor would be the way to go- but it isn't. And when I look at it- there's no way the sender is M10!

So, I wonder what the next 'likely' combination? would the sender thread be M14 x 1.25..?

Take the guess work out and measure the thread diameter. Digital calipers can be had for a tenner fiver now and get a set of pitch gauges too, theyre pennies if you go chinese. invaluable in the toolbox.

are you going to remove one of the plugs in the oil filter housing and fit the adapter and temp sensor there?

pitch/thread gage would be very helpful as often sensors use not metric thread pitch

Thankyou, yes- that would have undoubtedly been the best course of action.

However, using my calipers, and a bit of 'thread matching', an educated guess (more than a guess really) identified M14 x 1.5 for the sender.

Results!

And; yes- at this point; to prove functionality- I am going for the blanking holes next to the oil filter.
The longer-term and correct orientation for this engine, is the threaded-wing sump from a 155.

Job jobbed.

you dont have any pictures of a 155 sump 'wing' with the tapped hole do you?

I can see on mine a flat area where the hole should be, i wonder if theres enough thickness there to drill and tap a hole or if the 155 sumps had a boss?

As i'm working in that area now with the inlet manifold off, i reckon i can get a hole drilled and tapped there, already got a sender suitable for the vdo gauges

Hey Desperado-

as it happens- I do have pictures of the 155 sump-wing, with gauge-sender in; but they are on my machine at work (oops!)

So, it'll be Monday before I can put 'em up.

My shots also show the 155 oil-pressure sender, which is mounted where we have the low oil-pressure switch (on the rear of the block; between the starter motor & alternator)

And that's next on my sort-out list..!


whilst we are on the subject; does anyone know what the intention of these blanking plugs is on the oil filter housing..? Would they be for a non-thermostatic oil return loop; through an oil cooler..? Would one send, and one return..?

Well it worked for me!

Seriously, the last thing i wanna do on a Saturday night is bleeding defend myself rant.gif

Dante, you must have got a different threaded oil temp sensor to mine because mine is M10 x 1 Female M18 x 1.5.

Attached Image

My oil temp sensor fits perfectly in this adapter. It just does!

This is the baby i brought. It fits right into the LMA adapter.

No freekin' guess work going on here

So there tongue.gif

Oh, sorry Ganz!

You certainly don't have to defend yourself to me- no one could have greater respect for your efforts, or the documentation you have made public for the greater good.

I apologise if I didn't make it implicitly obvious earlier; that yes indeed; I sourced a completely different sender to yours!

And then didn't think anything else about it! But of course I have been trying to sort an adaptor for this particular Alfa 155 sender.

I didn't go into wider detail (as you had yourself) as I didn't think the chances of anyone wanting to repeat the strip-down of both a 155 dash and Lancia dash, and make a combination hybrid instrument pod were very high!


In short- this is a solution to my own problem; and not meant as an alternative to your own solution, which has obviously worked very well, and is likely to be repeated.

Thankyou again for going into such detail.

(Now, does anybody know what time it REALLY is, here in the U.K.!?? The clocks have just gone back..)
