Sooty.......80 TDi Timing Belt Help

[als2]

Well, finally ive a bit of time to myself and life's back on track for the first time in a while.... so, its time to give Sooty a make over which i promised her !!

So mechanicals first ive been doing al the bushes, arms, links, brakes, servicing etc etc but im off to do the timing belt and wondered if anybody could point me in the direction of any guides etc or any choices tips or tricks??

I was planning on bumper left on but slam panel and rad out. Is this enough room or better bumper off as well? and lock up tools, special needed or the usual drill bits?

Any help much appreciated guys as always.



Ps. paint next, followed by new interior bits and a fresh set of alloys.

I'm not that familiar with the 80 but would think you'll have sufficient room to work without taking front end off I may be wrong. On later a4s I use sliding pins to bring front end forward 12 inches which allows easy access. Looks like process is as follows.
Set to tdi using flywheel to bell housing marks.
Make sure cams set by placing locking tool in rear of camshaft against top of head.
Lock fuel pump in situ with timing pin.
Loosen cam sprocket from taper and remove belt.
Replace timing belt and tensioner ensuring timing marks aligned.
Set tensioner by lining up pointers and torque up.
Tighten cam sprocket.
Remove locking pins and turn over by hand a few turns put crank back to tdi and ensure cam setting plate can be inserted and fuel pump pin can be inserted.
Check tensioner.
If all lined up rebuild and enjoy.

Thanks Monkey much appreciated, anyone confirm if the whole front end need to come off???

Personally, I would favour dismantling the front end to get full access as removing the front bumper and slam panel is a doddle.

if avant is same as my coupe then i would second that. however did my brothers 16 valve petrol recently and access was good and job done in 1.5 hours. taking the bumper off would have created work on that occasion

I havent dont the timing belt yet but my alternator belt went a few months ago and for the extra 5-10mins it took to get the bumper off I would say it makes life a whole lot easier when accesing the lower pullies etc.

as i say not familiar with this engine in 80 so not sure about it. can only comment on 4 cylinder petrol and there is an acre of room ha ha. just did alternator on petrol coupe and very easy. but as everyone agrees front end comes off very quick and allows you to see square ahead without bending head round corners.

You will also need a new rocker gasket as there is a locking tool for the rear of the camshaft which you will need, as the cam belt sprocket is on a taper. Is your engine code 1Z?

Do the water pump at the same time, my mechanics never took the bumper or rads off I think there's plenty of room

As last comment says you will need a rocker cover gasket just remove the Rad fans more than enough room 6mm allan bolts on the crank pulley and the rest is straight fwd no grief whatsoever
use a CV joint bolt to lock the pump out from A4 if you have one handy use a file to lock the cam out and remove tensioner and idler pully and refit

and replace water pump it is a pain you have to remove the oil pump pulley on some models
