Timing chain replacement (2006 Honda Accord)
I have a 2006 Honda Accord with a 2.4 l 4
cylinder engine. I have taken the old timing
chain off the engine.
When I put the new timing chain on I need
to be at top dead center compression
stroke correct????
Is there a way to tell if the Cams and
Crank are in the correct position besides
just the markings on the sprockets???
The cam sprocket's markings also aren't
at 12 o'clock and pointing at each other in
the middle. I am lost SoS. Please
Hopefully this helps check out my YouTube channel for weekly updates

I've never worked on a Honda timing chain but I know it is an "interference engine" meaning the pistons will hit and damage the valves if you rotate the crankshaft or cams with the chain off. I am thinking that you can put the new chain on and it will be "in time" if nothing was moved. Okay. On your "K model" engine, the #1 cylinder will be the first one on the passenger side. Also, Top Dead Center (TDC) occurs on both the power stroke and the exhaust stroke. You want it at TDC on the power stroke, that's when all valves are closed and the cylinder will hold pressure when you apply air pressure. (Exhaust stroke...exhaust valves are open.) Okay. Put the new chain on and rotate the engine clockwise with wrench on crank pulley bolt head to see if the marks line up and they should. Check a video or get help if this is your first one. I would feel awful if the engine gets damaged. I never did a Honda.
Thanks autorepairtips1 for the diagrams! That's the easy/sure way to find TDC. Just don't rotate engine with chain off....and go clockwise only.
Wat if I already rotated with the chain off?? Damnit I probably messed up any chance of this repair turning out good...lol
It probably could not hurt anything turning it by hand while removing the chain. If you came up to some resistance while rotating cam sprockets by hand, it would just stop. Try to think what you did and put it back where it was. Markers on the cam sprockets and crankshaft will hint the shortest way to get back into "time". If you have to use a wrench, be very gentle and feel your way back into proper timing. Take your time and you will be okay. These parts are pretty tough but don't get jammed up, or use too much force with a wrench. You can do it.
These are awesome answers. At least I feel like I have a positive path to head down. If I have any more questions I'll post them w/ pictures. Thanks guys. #Hornet_2497 #autorepairtips1
