Follow Les Andrews book. (it also helps if you mark the correct teeth to mesh in white highlighter). I've sent you an email of an article I wrote a year ago for our local clubs in UK and Australia.

Re: Change timing gear easy way?
You'll need to lift the front of the engine a little to remove the front motor mount and timing gear cover. I then keep the gears from turning by placing a rag between the crank and cam gears. I then use the special nut socket to remove the cam nut. Here's a picture of a tool I made to fit the cam nut. The dealers also sell a good tool to do the job.

Re: Change timing gear easy way?
Here's a picture of the timing marks. Some books give wrong information on the timing marks and they might have you set it one tooth off. As the picture shows, the cam gear dot lines up with the crank gear tooth directly above the RIGHT side of the keyway.
Be sure to put some grease on the cam gear plunger, and I also grease the gears so they don't start off dry. |

Re: Change timing gear easy way?
With engine remaining in car, & not removing radiator, just installed an aluminum timing gear manufactured by Mr. Dan McEachern.
To insure engine remaining in a fixed position, used a Model A screw jack, (as opposed to hydraulic jack), with wood block on top to avoid denting oil pan or scratching oil pan paint. Also used same methods explained by Tom in reply #3 & #4 above. Used a 1/2" socket w/plastic screwdriver handle, turned with pliers, to remove the front oil pan bolts. Broke off plastic handle so it would fit in this tight space & could clear the tie rod below. Small mirror helps to see timing marks. Last edited by H. L. Chauvin; 04-17-2013 at 01:26 PM. Reason: added mirror |

Re: Change timing gear easy way?
I understand the timing marks line up on the gear with the dimple and "0", but my question is my new timing gear can only be put on one way right? The top and bottom hole look to be offset. This is my first model a and i just want to be 100% before i put the timing gear on. Its been a real chore to get the old one off since the fiber gear that was on there completly came off the inside middle of the gear....

Re: Change timing gear easy way?
Be sure the cam gear is NOT a 2 piece, like you old one.
Make sure the cam gear dimple lines up with the right side edge of the keyway, as this picture shows. |

Re: Change timing gear easy way?
It is not a 2 piece, its a billet one piece. And i will pull the crank pulley off so i can see if the keyway is aligned as shown. Thanks again

end quote I'm not sure that you really want to pull the crank gear, its a real job. It does not have to come off to change just the cam gear. |

Even if you have no idea what I just wrote when you are done the marks must line up like in Tom's picture.

Im not planning on taking the crank gear off, but between it and the nut a round piece of metal just big enough to cover the gear all the way around so i cant see the mark on the crankshaft timing gear. |

Re: Change timing gear easy way?
See that keyed circular piece of metal laying above the cranksahft, that's what im talking about, its just big enough to cover the "0" mark. Guess i could just go off the tooth just to the right of the key and hope thats it...

Re: Change timing gear easy way?
Randini509: Where are you in Washington? There are a LOT of Model A guys in WA who would be glad to come over and advise you during installation. If you're in Vancouver, I'll cross the river and give a hand.

Re: Change timing gear easy way?
Just pull the pulley and the slinger and install the gear. It is hard to see the mark on the crank gear with the slinger in place.

Re: Change timing gear easy way?
Well what I did was turn the crank until I saw the key, and stuck a small screwdriver between the slinger and gear, I can see the zero on the tooth :-) problem solved
