HUH? You mean turn it for a valve adjust?
Put a 19mm socket on a long extension then find the webbed hole in the splashshield behind the drivers side tire. Turn the steering all the way to the left.
Jam the socket/extension thru the hole and fish around till it gets on the crank pulley bolt.
The engine will be way easier to turn over with the spark plugs out.

Thanks a lot. so i don't need to take the driver side wheel out. a question why it will be easier with spark-plugs out?

If you remove the wheel, you'll be less likely to forget that your socket & ratchet-handle are attached when you start the engine.

make sure you use a duct tape to tape the 19mm with the extension, the arsehole in the plastic guide will drop the 19mm once you try to pull it out.

That should work. On my 6th gen, I used two 4 inch (I think) extensions.

i have a 3/8th's extension, 12 inches long(i think) plus . you dopn't have to take your tire off just turn it all the way so u have clearance. Also make sure you turn the pulley counterclockwise DO NOT ROTATE CLOCKWISE

don't mean to hog the post, but i just learned something if you remove your plugs, turning the crank pulley will be a lot easier. My ? is do you take them all out or just one.

All. If you remove one, you will get 0 compression in only one cylinder. When you get to the compression stroke of the other cylinders, it will become hard to turn again.

i remember that the haynes manual said to reach the TDC position, turn the crankshaft clockwise. afterthat, turn it counterclockwise to set valves, am i right?

The reason you only turn it forwards (counterclockwise for these Hondas) is the timing belt has a small risk of jumping teeth when turned opposite the normal direction of the engine.

Default Re: how to rotate the crankshaft? (JimBlake)

do i have to open the distributor cover to make sure that the distributor rotor points to the number 1 cylinder when position number 1 piston to TDC on the compression stroke. the description on Hynes is a little bit confusing.

am i right that when the camshaft turns two 360 degree (one for compression stoke, one for exhaust stoke), it goes back to the same state. so there are two states when the arrow on the camshaft pointing "UP".

bump for that....hate to steal the thread but tdc instruction on the haynes manual SUCKS. if someone could explain how to get tdc for piston 1 in detail id appreciate it

That blade is off-center, so it should only fit one way. Problem is, it's not too too far off, so it's possible to force it in backwards. Don't force it, it should go together nicely.

When the marks on the crankshaft are lined up, the #1 piston is up. If the arrow on the camshaft happens to be pointing down, that just means it's at the top of the exhaust stroke, not the top of the compression stroke. In this case, turn the crankshaft one full revolution. The camshaft will turn 1/2 revolution, so then the arrow will point up.

Honda used a couple different types of markings over the years.

Thanks. just figured out the relationship of camshaft and crankshaft this afternoon. i found that it is pretty straight foreward for 97 accord that the TDC of the number 1 cylinder is just the position when the arrow on the camshaft pulley points up. so there is no need of check the distributor rotor. only thing i found somehow usefull is that i can check whether the TDC on the crankshaft is sychronized with the camshaft marks or not. it looks pretty accurate for my car. don't know whether it means that the timing belt alignment is good.

If your timing marks all line up in the proper manner, that DOES mean your timing belt alignment is good. That's exactly what those marks are for.
