    Hello Everyone! Hope you are having a good weekend!

    I have some questions. I hope that you can help answer them.

    I replaced the timing belt.
    I didn't notice that something was wrong. Everything looked good.

    I turned it a 1/2 or 1 turn (I don't remember) to see if the chain was right, but the cam wasn't attached. It turns out, the pin wasn't in place.
    Everything was tight, but the pin wasn't all the way in place.

    Accidents happen.

    I know that now that the motor timing is off.

    Here's what I've done: I took off the rockers.
    And this means that the cam is free/loose/not connected, right?
    And it doesn't look like the rocker pins are bent at all.

    In order to put it back together and get the timing right to the stock position, is the following right?
    1) Can I manually move the crank shaft and put it in TDC now that the cam is loose since the rockers aren't there?
    2) Nothing will get bent, right?
    3) And that will put everything in time (technically without the chain) when I put the cam pointing to the crankshaft, right? Then I'll put the chain and gears on and will make sure the pin is in place in the gear.
    4) And then I can move the distributor to cylinder 1, right?
    5) I've seen online that many people use a timing wheel. It seems they use it to advance/change degrees. I'm keeping mine in stock position. Can I do this without a timing wheel?

    Will my plan work?

    Thank you for your time and feedback!

    You need to put the pin back in so the gear can turn the cam. There is a small punch hole in both gears. You need to set them up to where punch holes are perfectly aligned. Than tighten both bolts.

    Thanks! Does this mean my plan outlined above will work as I described?

    No, you not need to have it TDC when installing the timing chain. When you line up the to marks on the gears and install the chain it's already TDC. If you removed the distributor than you would need to find TDC.

    looks like I need a large Pin. I'm installing A double roller chain , and the pin is not long enough to keep the eccentric in place.

    If you add a little ball bearing to the cam side of the short pin that will push the pin out enough.
