Re: Just when I thought I understood A timing...
Here's a picture of a crank gear from Brattons, look at my picture. the timing mark on my gear is four teeth to the left of the key, on Brattons it's just to the right of the key

Re: Just when I thought I understood A timing...
'TDC is TDC, if I rotated the crank one turn, it would be right back in the same spot.'
The piston will be "back in the same spot" but the valves will not be in the same spot. See Vince above. Thanks Vince. Rotate it and view it visually and you will get it. The marks are fine, don't worry about them being in the wrong place. |

I think so too. On the following 3 pictures, check the position of the mark on the crank gear relative to the key. Here's Art's... Here's the red book... Here's a pic Tom posted on another thread... The red book and Tom show the crank gear timing mark about 1 tooth to the RIGHT of the key. Art's is about 3 teeth to the LEFT of the key.

Re: Just when I thought I understood A timing...
I actually checked this before I pulled the crank out, who-ever put the engine together before me aligned it the same way... which would only be natural I guess. The mark is very small, I'll make a bigger and better one where it's really supposed to go.

Sounds to me like you have confused yourself with the two dimples in the timing gear. Barring you being super unlucky and having a gear that has been marked incorrectly, you can't go wrong. The crank gear AND the camshaft gear can only go on one way. It's only the relationship between the two that we have to get right.

Re: Just when I thought I understood A timing...
Good catch by Vince and Dick re the crank mark being off. I missed it. Where did it come from?
As my guru says, assume nothing is right. Check and measure everything. |

Re: Just when I thought I understood A timing...
With the Model A ignition timing as flexible as it is (you can move it where ever you want) I guess it really doesn't matter what method Ford used to time the cam.

Re: Just when I thought I understood A timing...
I agree with those saying the mark on the crank gear is off by 4 teeth. Art, your kind of luck is very familiar to me.
I also agree with marking the correct tooth on the crank gear (go 4 teeth clockwise) and meshing them again. I think you'll find things are right then.

Re: Just when I thought I understood A timing...
Actually he needs to move over 3 teeth.

Re: Just when I thought I understood A timing...
Thanks for everyone's input, I know what I need to do now.
Mitch... get a bigger screen. 8^) The mark looks like a punch mark and is hard to see in the picture. |

I've never seen a thread go to 3 pages so quickly. I saw that tiny mark, but thought it was just a nick from handling or some such. I was also wondering if the gear might be on backwards and have a timing mark on the other side? Use a dental mirror to check the back side teeth next to the keyway. |
