Timing belt change - parts?

Dead easy job imho...but then I've not changed the clutch yet :lol:

A flywheel locking tool makes life MUCH easier and you'll need another "special" tool to remove the Balancer shaft bolt.

Then it's just like doing the belts on any car really. Thought I posted my experiences recently....
If you change the water pump you'll need to drop the engine, I managed by just taking out the upper and lower engine mounts (belt side) and letting it down the inch or so that it drops.

Edit: I'm wrong, my only post was this:

Not a bad job to be honest...just time consuming :rolleyes:

I can confirm that dropping the engine 25mm (undo the top and bottom engine mounts) will give enough space...although I did have to get naughty and use a crowbar to get the WP pulley wheel out :eek:

So none of that nonsense that the manual tells you!

This might help too:

thanks, Wrinx - I'd forgotten about the flywheel locking too - will have to make one - not so sure about the other special tool that is needed. It'll probably still be two weeks before I have all the stuff. I've never changed the timing belts on a car before - hence my apprehension. I am not planning on changing the water pump - if it fails I will use an electric one instead anyway. Any hints on the problems associated with changing to a 'non ac compressor' config?

thanks, jimn~

Gery has also asked this question http://forum.berlinasportivo.org/showthread.php?t=1279 and I can confirm it was AJ who did this as his post is at the top of this very thread :lol:

Doing belts on cars is fairly straight forward....just make sure the timing marks line up correctly, tension the belt so it's tight when twisting approx. 90degrees by hand, along it's longest run.

These are the timing marks:

Rotate the engine BY HAND at least twice after fitting the belts, to check for valve to piston contact and other nasty noises.

Got to be less difficult than the clutch...few hours work really. I remember you wanted a guide which typically I didnt get round to but I did find one on the Fiat Coupe website:

BTW, when the water pump breaks it doesn't just stop pumping water, it leaks everywhere too :(

...although hopefully you'll get some warning like I did, fluid leaking and copious amounts of steam :rolleyes:

I received my timing belt kit today - I'd like to put it on before I use the car again. Should be interesting. You can see the part numbers of the various components in this pic.

cheers, jimn~

Does someone have a pic of what looks like to mark for the countershaft pulley (intake side)?
I?ve always aligned to the bolt of the water pump iirc.

@jimn, great to have the parts #, thanks!

That is correct - pointing down.

Same as the picture posted above :deal::fp:

Wonder if this would help with the BS?

OK - so I didn't read the post below from Ringman well enough (see below...) - so i DID get soaked! Apart from that removing the belts was (pretty) straight forwards! The belts both look to be in sound condition but the bearing for the lower balance shaft is in very poor condition - I think that just the belts were changed on this car - not the bearings.

I removed the 22mm nut on the crankshaft with a rattle gun. Nothing to it.

The balance belt could be twisted on its longest length about 180 degrees - the timing belt about 110 degrees.


Ok.. The Big Question!!


I think I know how to put the thing back together... but I want to convert the car to a NON air conditioning compressor system by removing the AC compressor. Can I just remove the compressor and use a belt direct from the crank to the power-steering pump in its current position ** OR ** do I have to move the power-steering pump to a new position? Do the AC cars have the correct mounting hardware if I have to move the pump?

thanks, jimn~

It goes through a water jacket so when you take it out, you'll get soaked :-)

I think the only other thing that gave me trouble was that bl**dy PAS & AC arrangement.

I'd guess you can just remove it and stick the non-aircon belt on....was AJ able to help?

wrinx

no - the ps pump will need to be moved for it to be driven direct from the crank belt location that currently drives the AC compressor...the question is does the setup I have contain this new mount point...


jimn~

Doh..the PS pump is the top one! I thought AJ had done this...someone certainly has.

I need to check ePER but there's possibly a different bracket available...which flags up a vague memory of someone fabricating their own as the OE version was too much or unobtainable.

Same guy who fabricated his own inlet manifold I think...does that remind anyone else???

djsly maybe, will need to trawl through over on .org...

Maybe this will help:

I wonder how it is done on an Integrale...

Hmmm, I wonder who knows......:rolleyes:

It's a separate belt which runs between the AC pump and the PS pump which has a twin pulley on it. :smoke:

I had replied to Jim & Gery83, but yes it is possible to do away with the AC pump. The PS pump then moves down slightly (I think taking the upper mount from the original AC pump mount, and the lower of the original PS pump mount).

The twin pulley on the PS pump can then be reversed (3 bolts) and it will be in line with the crank pulley.

You can't run a straight belt from the crank to the power steering pump in the original location. All the mounts are there for it to be lowered if junking the AC pump - nothing extra was needed (on a Coupe 16vt). It might be a bit of a PITA with it all in situ, but far from impossible.

thanks AJ!! Will give it a go today. From what I can see the front cross-member will need to come off first - but maybe not :)
