Timing Gear
 

Replacing Timing Gear on my 29 Tudor and ran into two issues. First of all there is no circle stamp on the Crank Gear. There is a small slot at top of metal guard in front of gear at the key way. Could that be it? Secondly Timing gear teeth are badly chewed and things must have moved. Any tricks for realignment?

Here is a picture of the timing marks.

Check to be sure that the tick mark on your crank gear is slightly clockwise from the key slot. It's pretty clear from Bob's picture what I'm talking about, see also below for my engine. I understand that there were some aftermarket crank gears several years ago that had that tick mark one tooth anti-clockwise and therefore the timing of the crank to the cam would be off.

What you are calling "small slot at top of metal guard in front of gear at the key way" might be the oil slinger (visible in Bob C's picture). That "metal guard" is likely the oil slinger, and it pulls off forward to expose the crank gear. Once you have the crank gear exposed you should be able to see the mark on it.

A picture of what you see and what you are confused about would help us.

If your camshaft timing gear teeth are badly chewed, introducing slop, then you should change it for new. Aluminum camshaft gear, although a bit more expensive, will last longer. If it's your crank gear that's badly chewed you definitely should replace it. A worn crank gear will quickly destroy a new cam gear. It's not trivial, but by no means impossible, to replace the crank gear with the engine in the car. Most folks cut the gear off carefully with a cutoff wheel (two places) then heat the new gear to help it go on.

I've heard of people installing the crank gear backward so the punched mark isn't visible. Might want to check for that.

Re: Timing Gear
 

It is possible to time the crankshaft without any marks by the valve action. But it is much easier just to line up the marks on the gears as noted above.

Took picture as suggested and mark showed up. Can't see it by just looking at it which explains the slit on top of the oil slinger. The mark is down behind the slinger. Don't know how to upload picture. Thanks for the help.

I ground teeth off old timing gear and used it to line up timing mark with crank mark. Worked great. Just and FYI.

Katy what do you do after uploading. The picture comes up and nothing else with it.

Write your message then click on the paper clip to add the picture.

It's usually easier to take a cold chisel that is sharp and crack the crankshaft gear to remove it rather than grind it and potentially put metal shavings all over the place and into the oil pan.

Thank you I will keep practicing.

Re: Timing Gear
 

I would be reluctant to do this. Babbit does not respond well to shocking as you would do with a chisel on the gear.

Yes - The diagram in Les Andrews' book is wrong.

I don't see any paperclip in "Go Advanced." If I click on "add image" I get "enter the URL of your image."

Re: Timing Gear
 

The paper clip icon is at the top of the light blue field, just to the right of the happy face icon, put your cursor on it and it will say "attachments", click on it, simple.

Thanks, Katy, for looking out for the elderly, LOL. My dated eyes failed to see it. Blessings
