Technical 1982 1500 X1/9 timing reference

[Espritstu]

Hi looking for advice on a visual ignition timing mark set up
Just changed all parts in distributer including points as I had a loss of power and misfire
Now it starts up first time but have not driven it yet as looking at timing does anyone explain my set up
Timing belt
Crankshaft white line up at mark pointers and white paint dots at cam pulley for belt line up Rotor points at cylinder 1
I rotate a full turn on crankshaft to markers again and now cam pulley timing etch lines up tdc with cam cover plate arrow
Which I noticed a little square dimple at top of cam now Rotor points at cylinder 4 basically does this seem to be in time
Bit of a story but someone with the knowledge will hopefully understand what I'm trying bto explain also gap seems 0.4 mm
Thank you to everyone again

Looked through some old Technical Data manuals, this is all I got.
Note I couldn't find the 138 AS 000 Engine Series in the old cam belt book as they don't list the X19 at all,, so nearest I got was a 138 B 000 as you can see below, so don't rely on it !!!

Hi and thank you for your reply great information looking at the drawings and data sheet looks more or less there unless I'm not seeing something again thank you I have attached my photos as I mentioned

I’ll try and find my X18 manual, are you absolutely sure on engine code?

Hi never looked at code will have to do that if need be but looks similar to the drawing and points gap setting at 0.4mm

Be sure of the engine code, on…an AS 000 code sounds like a 128

Hi can I find this code on the owners Manuel or on engine thanks

You are just doing ignition timing so ignor cam belt marks.

You want your points to just open at 5 degrees before tdc for cylinder 1 or 4 (it works out the same) as you are not using a timing strobe.

Set crank to 5degrees before tdc then turn distributor body until points go from closed to only just open, tighten the distributor lock screw to stop distributor body from rotating-reassemble everything else=job done.

Ps clean the centre brass contact of rotor arm with green scourer

Hi so just starting to open on the middle pointer of the 3 as I mentioned previously also the photos my points at the position are 0.3mm but if you hold the distributor shaft as in slight play ( backlash ) in the forward movement opens at highest point 0.4 mm then closes again if this makes sense thanks

I don't know which pointer it is.....but measure from centre of crank pulley too pointer in millimetre, multiply that by 2, multiply result by pi = circumference in mililmeters at pointers
Divide that by 360 and you have millimetres per degree
Measure back 5 degrees worth of millimetres from tdc pointer then you know which pointer is 5degrees before tdc

 

[jackwhoo]

Only turn engine in normal rotation to set 5 degrees before tdc.
Lots of reasons why.

Ok so rotate to position pointer 5 degrees and will that be just the point gap opens

 

[jackwhoo]

Turning crank in normal direction only set it to 5degrees before tdc,stop turning crank,

then turn distributor body until points go from closed to only just open,

tighten the distributor lock screw to stop distributor body from rotating-reassemble everything else=job done.

If you have an electrical meter you can be much more accurate than guessing when points open by looking at them.

I went from the Engine Series Number in an old Auto Data for the X19 as it was the only information for that model I could find.
I see the OP mentions distributor bearings worn giving a variation in the points gap, obviously the higher the revs the wider the gap will become.
As a slightily more accurate measure under running conditions a Dwell meter may help, until distributor reconditioned.
The "hooked" cam pulley marker does look similar to the one for the 138 B 000 in my mention at #2 and the only mention of the X19 was that Autodata photo mentioning the 138 AS 000.
Sorry I don't have much information other than that.
I did find an old Haynes manual 1167 of the Fiat Regatta that mentions a 1498cc but it is the 138 B 3000.
Not sure if any good as with X19 rear/mid engine mounting if any major design differences.
In all honesty it was never a model I did much work on as compared with the then current convention of front engine and rear wheel drive set ups which were easy to work on, it was felt some instruction on "gynocology" may be needed.

It was actually easier to work on than the folklore…yes some bits were a pain but service bits were easy…
As for manuals, somewhere I have the Fiat Workshop Manual

In fairness there were very few in our area so a bit of an oddity, any Fiats that came in were more likely 850 saloons and coupes, 900 camper vans, 131 and 132s, once a 2300 saloon and of course the Ladas (124 under license) thinking back it was probably a 1300 X19 when working for the Mazda, Wartburg, Lada and Moskvich Dealership around 1975-82, however as garage had been agents for many different makes over the years, we worked on a wide variety as I had done whilst serving my apprenticeship at a different garage.

Good feedback from all thank you again
