How do you find TDC on a Honda Civic D15B7 with the crankshaft pulley attached?

Question

Is there an easy way to find TDC with the pulley attached? I don't want to remove all the accessory belts and take the pulley off. Are there marks on the pulley, or should I use a probe in the spark plug hole to find the top of the stroke? Which piston would I use?

Answer 1

Okay, to find top dead center on any internal combustion motor, do this:

Remove the number one spark plug and put your thumb over the hole. Turn the crankshaft pulley until you feel the air start to push your thumb off of the hole. At this point, place a long socket extention into the hole. when you feel the piston raise as high as it can, and start to go back down, turn the crankshaft back until the timing mark on the crankshaft pulley aligns with the 0 mark on the timing meter. That's it!!
P.S. It's a good idea to make sure that you disconnect the battery to prevent an accidental shock from the wire.

cappi01 is telling you straight. Remember, gasoline engines like this D15B7 are four stroke engines. That means the piston is going to be at TDC twice for each power cycle... quickly reviewing:

1. Intake stroke (down) sucks in air/fuel mixture
2. Compression stroke (up) compresses air/fuel mixture
3. Power stroke (down) combustion forces make you go!
4. Exhaust stroke (up) pushes out the exhaust gases

Top Dead Center or TDC as it is refered to in the books, is at the top of the compression stroke... not the exhaust stroke! That's why cappri01 has you put your thumb over the spark plug hole... to find the compression stroke.

When you are on the compression stroke, stick an extra long screwdriver or a long wooden dowel, or anything that fits and is rigid enough to show you movement of the piston. Now turn the crankshaft until the stick (whatever) is at the very top of it's travel. THAT is TDC. At that point the rotor in the distributor should be pointing toward spark plug #1 which is the closest spark plug to the crankshaft pulley.

If you disconnect the battery, beware that your radio could default to it's anti-theft, does not work without radio codes mode. You needn't worry about spark plug shock if you remove ALL of them and set them aside. Remove ALL the spark plugs or turning the engine over by hand will be very difficult if not impossible.

The question remains as to why you are doing this as it is typically only done when replacing the timing belt. If you are using a timing light to set the timing, the strobe should indiate a value of timing as BTDC or Before Top Dead Center. Spark plugs need to fire ahead of TDC so the air/fuel has time to ignite and produce pressure... to much BTDC and you get engine knock.

Good luck!

Answer 5

there should be a red mark and a white mark (dot) on the inner edge of the pulley , there should be a pointer on the lower timing belt cover just line up the white mark to the cover pointer and that should give you TDC

Answer 6

Word to the wise always disconnect battery when working on an engine...

Answer 7

Use the marks on the flywheel/driveplate to set TDC. If you want to make sure about it, you can probe No1 cylinder. No1 is the piston farthest from the transmission on that engine.

i think TDC is marked on the timing belt

Answer 9

rotate the crank until the number one piston is up of look for a timing mark
