need advice. working a 2000 A6 2.8 Q timing belt.after seting the crankshaft on marks,i took apart the timing belt,H20 pump, tensioner, tensioner lever andpulley all of them to be replaced with new parts, the question is, without moving the camshaft and crankshaft sprukets should i be concern about timing upon replacing the new belt? im puzzled at why seemingly every or most are of the oppinion that the timing needs to be done. secondly can any one tell me where to locate the crankshaft holder opening on this car? i use ALLDATA online manual which has a crapy sketch of this. plz help am alittle desperate at this point

 

its not the sketch you should be worried about its the use of special cam locking tools you need otherwise your in deep **** as the CAMS WILL BE OUT OF ALLIGNMENT I suggest extreme caution and get someone to give you advice and assist


quick edit: hopefully this will help you might find some useful pictures in there

Since you already pull the timing belt out, use of the crank shaft lock is irrelevant at this point. Crank only locks at one location. If the orientation of the crank is not aligned, then you would have the turn the crank, which means that your crank is out of alignment with the cam. I say you go find a crank locking tool and a cam locking tool if you are planning to do the job right.

Otherwise you can put the belt back on as is, but you are risking misalignment once the belt is tensioned.

FIY, crank locking bolt hole is located on the driver sider toward the bottom rear of the block.

 

thanx guys for your quick rescue. am gonna go try will keep u updated

 

ok. i have replaced all the new parts. surprisingly every thing fited tailor perfect without dificulties making me wonder where is the catch.i must admit i have little knowledge ofwhereto put the marks on the cam, but those i put matchedafter the two crankshaft rotation test post assembly.I had a localy made camshaft locator bar which was used, but it would seem to have made no difference any way. i tried locating the crank lock pin opening after directions from you nice folks, but still could not find it, so i delt without. to be mention is the fact that, upon many 360 turns on the crankshaft post assembly, the belt at certain point seemingly feels kind of less tense on both side from the water pump pulley to the cam sproket left and right, while tension is maintained otherwise elsewhere. should this be of concern or is it a normal finding. i am still afraid to crank the engine, plz i need you opinion and encouragement

 

hopefully they are large enough for you to see, last thing we need is a skewed engine

thanx Dave, this is nice of you, youve tried to guide the best way you can through this adventure of mine. i did follow those steps except for the crank lock,using ALLDATA which is truely similar to what youve attached.because every thing is gone smoothly without me seeing the specific impact of the tools not otherwise used as directed, im kind of concern there is a catch. should i go ahead and crank the motor?

 

Sounds like the way the installation went, the worst case senario is a CEL coming on due to minor misalignment. If you are lucky, everything should be fine.

FYI, the whole point of using cam and crank lock, and loosening the cam gears is so that you can pre-tension the belt, and have equal tension on all sections on the belt. If one setion has more tension than another section, one cam can sligtly misalign once the tension on the belt equlizes. Hopefully it is not to great to throw a code.
