Don't believe anything here. It's just a collection of words and images.

Apology. I promise, this will get sorted soon :-/

From: Carl Sweden. on 08 March 2005 at 08:14:13 (UK time) GoMy old cambelts (VVC) looked like new BUT the alternator belt seems to be of dubious quality. Hundreds of small cracks in the ribbed inner material,hard to notice as the outside of the belt looks fine. Roger P. has a very useful remark in his write-up on how to change the headgasket. By sligthly move the crank just a few degrees anti-clockwise when refitting the new belt it comes spot on. With the indication marks totally lined up at the crank it can be very difficult to get the belt on! As the Atlas camshaft bolts are kown to shear I changed them for Mikes "Lifesavers". Can be done without disturbing the installed belt according to supplied instruction. / Carl. |

(UK time) Dave, I've seen a DIY electric impact wrench for about £25, if I remember rightly. I don't know if you can hire these (you may even be able to hire an compressor and air impact wrench, but some hire firms are scary about the maintenance on compressors). Whether an electric impact wrench is man enough for the job is another thing. If it gets the pully off then after you've used it to refit and tighten the pulley you could get your garage to check the tightness with their kit. Perhaps a mobile mechanic with a compressor could crack and retighten the pulley nut for a few notes. Don't, by the way, fit the camshaft locking tool until the crankshaft pulley is loosened (does that sound obvious?). Loosen the pulley bolt a little, line up the pulley mark, check that the cam sprockets are aligned, fit the camshaft locking tool, take off the crankshaft pulley, then swap the belt Don't turn the crankshaft AT ALL! There must be absolutely no slack on the drive side of the new belt between the crankshaft pulley and the exhaust cam sprocket (that's obvious too). Check that the pulley mark is correct (the cam sprockets will of course be correct). Just hand-tighten the pulley bolt, take the slack out of the belt with the tensioner, remove the cam locking tool, and tension the belt as per the manual. Tighten the pulley bolt with whatever means you loosened it. I think that's it. If I've made any glaring errors someone will correct me. Good luck, just don't hurry, and check those cam/pulley marks again! Regards, Kes.

UK time A few things to consider: Make sure you set the cams with the markers on the pulleys facing each other. Also put a reference mark on the crank pulley (the timing notch is on the BACK flange of the crank pulley don't be confused by the one on the front flange!) You will need to use the breaker bar to undo the hex bolt holding the tensioner and a cranked 8mm ring spanner to remove the slider bolt. Water Pump and pipes The rubber hoses will be a bit of a pain to remove from the metal coolant pipes, be careful not to damage the rubber pipes. Re-fitting the cam belt. Now just the waterpump and tensioner. From experience I have found that it is easier to place the belt around the waterpump and then fit the big tensioner bolt (if you fit the big bolt before getting the belt around the tensioner you'll make your life a lot harder) you can just about see what you're doing if you bend the metal wheel panel into the wheel arch (bend it back again afterwards. Setting the tension is fun. use a LONG screw driver to push the slider up and use the 8mm setting bolt to hold it whilst doing up the big hex bolt with the breaker bar. Bleeding coolant. Do a 'sanity check' and make sure there is nothing loose in the engine bay. REMOVE the cam locking tool and start the engine if you hear 'chirping' the tensioner is too tight, adjust it and try again. (Note: don't re-assemble every just yet incase you need to re-adjust.) Sorry I can't help with the other VVC belt, I haven't done this before (shouldn't be too tricky if you can do the main belt). Don't expect to do all of this in one day, it may be possible if you have done it before but not as a novice. It's not worth rushing. These are not full and comprehensive notes but highlight a few of the main points you'll come across. Good luck Tim

NOCKENWELLENANTRIEBSRIEMEN –KONVENTIONELLE VENTILSTEUERUNG Ausbau VORSICHT: Nach dem Abbau eines Zylinderkopfes oder dem Austausch von Nockenwellenantriebsrädern müssen immer die Nockenwellenantriebsriemen erneuert werden. Nockenwellenantriebsriemen müssen vorsichtig gelagert und gehandhabt werden. Nockenwellenantriebsriemen immer flach ablegen und nie stärker als 50 mm biegen. Ein verdrehter oder zu stark gebogener Nockenwellenantriebsriemen darf nicht weiterverwendet werden, da die Faserverstärkung dadurch beschädigt worden sein kann. Nockenwellenantriebsriemen dürfen nicht weiterverwendet werden, wenn vom Abriebstaub abgesehen Schmutz oder Fremdkörper unter ihrer Abdeckung vorhanden waren. Nockenwellenantriebsriemen dürfen nicht weiterverwendet werden, wenn Kolbenfresser aufgetreten sind. Nockenwellenantriebsriemen, die mehr als 77.000 km hinter sich haben, dürfen nicht weiterverwendet werden. Ölverschmutzte Nockenwellenantriebsriemen nicht verwenden. Die Ursache der Verschmutzung MUSS behoben werden. 1. Massekabel der Batterie abklemmen. 2. Fahrzeug hinten anheben und auf Montageständer(n) absetzen. WARNUNG: Arbeiten Sie nicht unter dem Fahrzeug, wenn es nur durch einen Wagenheber abgestützt ist. Setzen Sie das Fahrzeug immer auf Montageständern ab. 3. Laufrad hinten rechts abbauen. 4. Motor-Hydramount rechts entfernen. Nähere Angaben in dieser Sektion.
