SOURCE: 1997AudiA6Quatro2.8L-aligning cam and crankshaft for timing belt

You must find the cam lock bar and crank lock pin to do this job properly, otherwise you can bend some valves and that becomes expensive..the front crank damper has a mark to line up with a mark on the timing cover for #1 TDC, but the cam lock bar is what aligns the cams into position. The crank lock pin is helpful but not 100% necessary...

Line up the timing marks starting with the crankshaft pulley. Rotate the crankshaft clockwise until the marks line up. audi-a4-b5-crankshaft-timing.jpg - See more at: http://www.happywrenching.com/a4/audi-a4-b5-28l-v6-timing-belt-replacement-removal-and-installation.html#sthash.FZPABPk1.dpuf

Diagram for engine timing for a 3100 Chevy V6


It's on TDC so align marks on cam shaft and crank shaft with center of cam & crank shafts and the ECM will go from there. so you will have to change the timing chain if its loose or worn out.

What is the timing procedure for a 2003 Audi A6 Quattro 3.0


there is a special tool as there are no timing marks, in front of the cam gears are plates with two holes in each (for location of tool) there is also a tool that protrudes into the crankshaft position sensor hole.. if you dont have access to the specialty tools , than i would engrave marks on the gears and covers to align to original positions.

I got a audi A6 2.4 v6 multi valve with the timing belt off, I need the cam postions at tdc 1


There should be a place on the front of motor either the left or right side that will show you when it is a TDC. Or look for markings where the timing belt goes on the pullys.

I am having troubles locating the cam shaft timing marks on my 1999 VW passat VR6 engine. any ideas


hi, here is a guide i have come across on this site written by another expert it should be the one for your engine but always double check.

If you are unsure what you are doing then please go out and buy a haines workshop manual as these tell you every detail you need to know so that would be your best solution.

Please dont do this work if your unsure what you are doing as you could damage the engine beyond repair so you have been warned;

it covers single cam and if you scroll down it shows double cam ok
