As above I am learning all I can about timing belts. As you may know I did my first one couple weeks back but sadly we don't get many in so I'm unsure as to when my next one will be :'(
However, I've looked at many procedures for sohc and DOHC belts and they're all much of a muchness now I know the basics and fundamentals.
So. What's the hardest timing belt you've done and why? Obviously omega would be up there if the handy dvd from oof unavailable.

Think you'll find the 2.5 V6 rover 75 is a barsteward to do as it has 3 of the blighters

Yep the Kv6 isn't the best to do but not so bad with correct timing kit,later Vag diesels aren't that great either especially the transverse ones,bastard engine mount bracket does not want to leave

I believe the fiat coupe was a bit of a pig

2.0 16v/ turbo is easy,20v turbo is engine out job.

If you include chains, the Audi Sx and RSx engines are particularly tricky. Yet also absolute works of art.
-
Anything front wheel drive I'd guess. Especially shitron belingo (?) van. Zero access as the drivers wing is half an inch away from the puley and tensioner.
French shart!

If I am allowed to mention motorbikes, the cammy-engined Sunbeam S8 from my all-too-distant past was an absolute dream to do........ ;D

Yup but same engine is in my LDV pilot and a piece of pish to do as it is located correctly inline and not incorrectly transversely :y
-
Bigger Audi diesels were a pain as the belts were close to the bilk head, even worse when fitted into Volvos.
If its chains think 2.0 diesel BMW ....engine out job and even then its shit.

done few of them so far and must say replacing timing belts is not bad job at all , just get to them that's other story

IIRC SAAB used to use an evolution of the Triumph Dolomite twin cam engine. The tricky bit was that they mounted it back to front with the timing chain facing the bulkhead.

I've been told about...
Bigger Audi's requiring the front end stripping, I mean radiators, bumper, lights - to access the belt.
Some 1 Series BMW are chain at the rear, so engine out
Renault clit 197? Engine out
The worst one for me was the 1.7TD Vauxhall engine (just post full Izuzu), dial gauge on the cam - that wasn't a PITA, no not at all.
-
For Audi read any VW group car with a longitudinally mounted engine...
Later V diesels are chain driven, again at the flywheel end ::)
-
I too have seen images of Audis with v engines (I thijk) where the timing gu bins is at the rear as Mark says near the bulk head.
Firstly, why? :o
Secondly are they also engine out jobs or can the engine drop down enough? How the hell does it fit to the transmission I.e. Where's the flywheel or torque converter positioned :-\

Last time I changed a timing belt-and the only cars I've ever done them on-was on the Mk3 pinto engine Cortina!

Firstly because they're retarded, and secondly you need to split the box... ::)
They are at least chain driven...
-
ah yes rear chain is now ringing bells. :y
are they all like that? is it just the big uns etc?

Al, interesting how in that video he had to loosen the actual sprocket to be able to get his timing pin in.
he then states that to be set up perfectly those bolts should be bang in the middle of the small channel they live in.....yet his ends up slightly off. how could he have got that bang on> any ideas?
-
ignore that, ive answered my own question..... if he'd have started at the crak pulley which is locked in place he'd have been able to feed the belt up and manipulate the cam sprocket where they were centred and withthebelt nailed in place.
I think :y
-
vw t4 2.5tdi, 2 belts one at either end and 3 tensioners,one of which you use to fine tune the fuel timing loads of fun to do not! :y
-
that sounds awful. head mech. is going to give me some more so i can just do as many as poss :y
question....
with a DOHC....
I thought if you had crank at tdc and locked, and cams locked correctly, youd then tension it correctly ad job done....but oh no ::) ;D
if i do this the tension side will be, well err, tensioned lol but not the 'drive' side (or the other side). head mech tried to explain how (generally speaking so dont anyone go all keyboard warrior-ish please!) you can loosen the sprockets and dial it in (like in the vid i posted) but ive got to be honest its gone over my head slightly. anyone care to elaborate?
for work though ill just keep beavering away and hopefully the understanding will come :)
