Yes, that's where the water pump sits.

Just corrected my earlier post - that's obviously the inlet cam I've removed, not the exhaust... blush.gif

The inlet cam is off so I can replace the variator....

To remove the variator, I clamped the inlet camshaft in a vice using the old cambelt as padding. It took a long breaker bar (with the correct removal tool) to shift the variator but it came off without too much of a struggle.

Below is the new variator in place ready to be tightened onto the camshaft (the tool is already in place) - and the finished product.

There is an oil seal for the variator (which I will also replace) and top and bottom bearing shells. These look in good condition, so there's no need to replace them.

Will be re-fitting and getting the car back on the road over the weekend!

Today I refitted the inlet cam plus all of the timing belt gubbins, completed the timing, and refitted the cam cover, coil packs and top engine cover.

Had some minor dramas along the way, as follows:

When I removed the water pump, I noticed it had been fitted the wrong way round (rotated by 180 degrees) and that the bracket used to attach the front part of the belt cover had been snapped off. I assumed this was to facilitate fitting it the wrong way round - as in this orientation the bracket fouls a moulding on the front engine cover.

I could see the screw that would have attached to this bracket was present on the belt cover - but seemed to be screwed into a blob of mastic. You can see this in the centre of the photo below:

So I decided to remove this section of the belt cover. This is where the second drama hit me - the screw at the other end of the belt cover, located on the side of the head, was seized:

Attached Image


Unfortunately, it sheared - but left enough of a stub to locate the belt cover on re-assembly.

On looking at the back of the belt cover, I discovered that behind the mastic was the broken piece of bracket from the water pump flange. I wondered if the screw had seized - but it came out easily. Here are the bits:

So I was able to fit the new pump in the correct orientation:

... and re-attach the belt cover as normal (apart from the sheared screw at the other end).

Weird. I have literally no idea why the water pump was installed that way - or indeed, why it was taken out then re-installed that way - because that's what must have happened... or how that bracket had been snapped off at all...

Anyhow, the rest of the belt installation was straightforward enough and the belt is now timed and tensioned up nicely:

The final drama came when refitting the cam cover - when I discovered one of the nine retaining screws was missing. And it was missing because the threads on the hole into which it should have screwed had been stripped.

Now, given this car had a full Alfa specialist history it's a bit disappointing to discover the above bodges. For example, anyone with the slightest knowledge of working with these engines would know not to overtighten the cam cover bolts - they only need to be torqued to a few Nm.

Anyway - no major harm done... just the balance belt to fit tomorrow and then we should be good to go...

I've also got a new cam cover gasket coming next week... I'm considering polishing the cam cover so am expecting to take it off again soon. I may try a helicoil to fix the stripped thread at the same time.

Finally, I discovered that my variator is of the old type and therefore not repairable using the repair kit I bought last week... hey ho...

My old variator was a b**ger to shift. It took a MAP gun and a pneumatic drill with socket to shift it.

Good work. Yeah defo polish the alloy. I do this at least once a month if not more. Stops the furring.

terrifying & fascinating stuff, Jeremy!

I've never seen such footage documented of the variator removal; great technique.

I wish I had your skills

You're most kind...!

Finished up today with the balance shaft belt:

Started the engine - it ran first time, as I'd expected. It was a bit clattery while the new variator filled with oil, also as expected.

Then refitted the cam belt covers, aux belt pulley and aux belt. The aux belt tensioner has seen better days so that will go on the non-urgent list of Things To Replace.

Re-fitted the header tank and topped up with coolant (Blue Paraflu) and drained some of the engine oil (I'd over-filled it when I changed the oil before Xmas).

And here it is - looking, well, exactly the same as it did before... rolleyes.gif

Went for a spin round the block and loved it, of course... rapid little cars, aren't they?

Well, here's a surprise... I had a "missed delivery" card from the PO when I got home yesterday - odd, as I hadn't ordered anything that would have been delivered via the Post Office.

Anyway, on collecting it today I discovered it was my long-lost delivery from Bulgaria:

These are 3D-printed replacement headlamp adjusters for a 145/146!

You may recall I considered this solution when trying to fix my shattered headlamp adjusters (see post #98)... but after several weeks of silence and crap excuses from the vendor, I gave up and (successfully) filed a request for a refund via PayPal.

Now here they are - although obviously many months too late...

crikey what a find-

do they look like they'll work..??


what kind of a mileage or time period would you put on the belts interval then, Jeremy..?

furthermore; is it accurate to say that the 2.0 has three belts, and the Junior & 1.8; two belts..?

The headlamp adjusters look right, for sure... I'm sure the adjusters on the other headlamp will break at some point so I'll try them then...

Timing belts - official replacement period is 36,000 miles or three years - whichever comes first. Based on the service record, mine had done approx. 10k miles, but hadn't been changed in 8 years.

The 2.0 is the only Twinspark engine with the balance shafts so it has the extra belt (although apparently you can leave this off if desired).

So yes, if you're including the aux belt then the 2.0 motor has three and all others have just 2 belts.

right.

(just thinking about the belts interval on your former/my 146!)


could you share your source for the 3D printed headlight adjusters..?

Yes, here's the link: http://manoloff.com/product/headlights-adj...lfa-romeo-1456/

On your car - don't forget I had changed the cambelt prior to it becoming yours... so you've probably got a few miles to go yet...

Had a meeting to go to today so decided to take the 145.gif for an extended test drive.

Total travel time there and back was about four hours of mixed driving - towns, A roads, motorway - and I'm pleased to say the 145 tackled it all with ease - excellent news!!!

Only a couple of problems:

1) The cheapo washer pump I bought to get it through the MoT will now only squirt the back windscreen - I've got a genuine Fiat/Alfa replacement, so will swap this in. This means I can also re-fit the original piping! Sad, I know, but - yay!

2) Re-fuelling takes a long time as the pump keeps cutting out... I've resurrected an old post on this question here: http://forum.alfa145.com/index.php?showtopic=20681

3) The car stalls at idle when cold. I'll try cleaning the throttle body first - but diagnostic info on this site is not always helpful as most relates to the CF2 motor on this subject. I may be back for more help if cleaning the TB doesn't help...

4) The tyres are 3x Goodyear and 1x some no-brand crap tyre - which is on the front right hand wheel. Left hand turns at speed feel somewhat vague - so a pair of decent new front tyres are probably a good idea.

Still, really pleased with the way the car went today - aside from the above, absolutely spot on!

that all sounds very encouraging Jeremy- amazing to think how you've turned it around into an everyday-usable vehicle; good for you


Do you think the stalling-at-cold issue could be related to the idle control valve, on the side of the throttle body..?

The FIAT-garage guys used to call it the 'stat valve'...

or is the CF1 setup different ?
