Technical Timing belt 1.2 FIRE 8V 2004 (EVO 1)

[koalar]

Thank you Txuchin
Happily mine looks easier, earlier version (shall we call it EVO 1? I want to call it EVO 1)
But good to see rocker cover stays in place, and timing marks applied.

OK, feeling confident about it now
Jock's guide warned me one of those engine mount bolts in the block is tricky for access.

Interestingly different timing marks used for the crank in those two videos (500 on left, Panda right), although both show VVT 1.2

Will be fascinating to see what timing marks I find on mine

One set with cylinder 1 at top dead centre (bottom photo)

The other is with all the pistons half way down (top photo)

Fiat changed the process when the compression was lifted as it's now an just about an interference engine

Makes no difference when using the tipex mark

I'd be tempted to go with TDC (bottom photo) or use the gearbox inspection home, regardless of the timing marks, as there's no spin back on the camshaft, I believe

If using the half way (top photo) there is definitely a bit of spin back from the valve springs, there certainly is on the evo 2 anyhow

I only use the half way only because I have the locking tools but only use it on the crankshaft if doing just the belt

That's brilliant thank you OK, so
Set crank for piston 1 @ TDC
Mark block, pulleys and belt
Remove tensioner and belt
Transfer markings to new belt
Install, fully tighten tensioner
2 full revolutions, recheck timing marks
Set tensioner

I think even I shouldn't be able to stuff that up.

I shouldn't have said that.

Any further suggestions for a timing belt novice gratefully received

Nope sounds good to me

I did a small job for a 2CV owner and next thing I had several of their local owners club as customers for several years.
I still have a small Sykes Pickavant hydraulic jig that could be fitted over the king pins and made the job of replacement much easier.
In the past I have had Citroen Ami's, Dyannes, Visa (with 650 aircooled engine) etc.

Well that's the price you pay for doing a job well
There were two 2CV gurus near us and they were in constant demand.
Until one of them decided they'd had enough and became a programmer...
Then I remember joining a queue of 2CVs outside Steve Hill's house in Haslemere with his family trying to get him to sit down to dinner
They had to move to France to escape us
Our last friendly mechanic in the area who helped with the Healey absolutely hated 2CVs and refused to touch them!

Sorry, another question about setting the crank pulley to piston 1 TDC...

Some of the references I've seen show it lined up with the step in the casing:

Some with this bump lower down:

Or somewhere inbetween:

How critical is this?
Or should I go by the flywheel instead?

Look at the camshaft pulley if it's keyed and has a timing mark, I'd go a different route

But If it's as I suspect keyless and with no timing marks just make your own tipex marks

Doesn't matter where you start as long as long as the cam or crank don't move in relation to each other

At the end of the day if you mark everything, don't move any pulleys, put it back exactly the same as you took it off, you should have no problems.
One critical thing is once all tight and matching marks etc. Turn engine by hand at least two full rotations of the crankshaft and match marks again.
If nothing comes into contact pistons/valves, then the worst that can happen is it doesn't start.
I always do that on an cambelt job.
I recall some years ago popping into the local Austin Rover Dealership and talking to their foreman, apparently one of their mechanics had just fitted a belt and tried to start the engine on a fairly new Rover 825 KV6 V6 engine causing £2k of damage at the time, so not very popular.

Thank you koalar, Mike

Glad I'm starting on a 8V FIAT
