Finding top dead center with a 9/16 wrench

[Blue Brick]

I mentioned that already in an above post.

A 1-1/8" socket with a 3" extension.

Thank you. Just to be certain, the correct direction to turn the pulley is counterclockwise or clockwise?

I do appreciate the assistance.

Clockwise. Otherwise, you may risk breaking loose the torque on the balancer/damper bolt.

Thanks. I will try spinning it this evening.

I’m sure you're familiar with motors, but I wanted to share a photo of mine for context.

UNDERNEATH, there is tons of room. If your gonna lay on the ground to turn a torque converter wrench, you can lay on the ground to properly turn the crank bolt.

Nevermind, already established... 9/16" on the pully bolts (200 in/lb), usually 1 1/4" on the crank bolt (135 ft/lb).

Except it’s a 1 1/4 socket not a 1 1/8. Kim

Oops, typo.

If you still end up using the TC bolts-

I'd use a closed end wrench.

It's easy to round off those relatively small, shallow bolt heads.

...and they are not cheap or easy to buy.

It's pretty tight quarters, and I ended up having a 9/16-1/2" offset wrench that fit and was extra long to boot.

I'm currently under the vehicle. The crankshaft dampener has several timing marks on it—how can I identify which one is the top dead center (TDC) mark?

We had trouble confirming compression at the cylinder, so we used the pencil method to find TDC. The pencil did move, indicating piston travel. While under the car, I noticed two timing marks already visible on the dampener, and a third one is approaching the timing tab

My crank wheel has the extra marks. Number 1 is a larger mark, and goes right across the wheel. The other marks go half way across, and are 90 degrees apart. I made a mark on the engine, that I line up the other marls with.

Remove the #1 spark plug, cover hole with finger and turn the crank with the ratchet. When you feel compression, keep turning clockwise until the next balancer mark lines up with the timing mark on the timing cover and you are now at TDC on the firing stroke.

Make sure you know which direction the engine rotates. (Bump the starter)
The added marks may have been added to indicate TOTAL timing, in lieu of a timing tape or degreed balancer.
So, follow 69Bee's suggestion, and when you get to the first mark, keep turning with the finger in the hole (do yourself a favor, pull ALL the plugs) and see if there is more compression. If there is, continue to the next mark.
When compression quits when you reach a mark (second, third, whichever) that will be tdc.

The distributor rotor, and the crank wheel, go clockwise on my 318. I had checked TDC with a dial gauge, to determine that the crank wheel marks were correct.Heads were off for the dial gauge check.

If you do pull that crank pulley mark it and the balancer for re assembly.
