VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

I have a bare engine on the 36 chassis. I need to pull the front crankshaft gear off, and brother do I need a hint.
The pan is off, and I'm staring at a gear. What now, I don't see any way.
The picture is WHY I need it off.

Why do you need to pull the crank gear? I can't tell from the photo. If you do, the crank needs to come out of the block and a gear puller attached to the gear. You may need to use a bearing puller on the back side of the gear then attach a gear puller to it. K.R. Wilson made a tool for the job, but they are hard to find.

Thanks for your thoughts. I guess I don't have to take it off. Is it pressed on AND has a key? I thought it might be work around. My issue is with the timing take a look at the cam gear placement. I think it is incorrectly installed.
The engine starts dependably and runs-but rough. After I opened it up I set up #1 TDC comp. That is the picture if I uploaded correctly. Note the cam timing mark UP, as well as the crank mark. Is that right?
The engine was overhauled in '77 but I am just now getting to finish the vehicle. I think the factory cam timing mark is the 1/4" "notch" in line with the distributor groove.

You do not need to remove your crankshaft gear! You just need to rotate your crankshaft one revolution to have the crankshaft gear and the camshaft gear timing marks line up correctly for TDC on #1 cylinder power stroke. You have them shown at the TDC position of #1 cylinder intake stroke.

The crank rotates twice for every revolution of the cam. The timing marks do not line up at TDC which is typical for the early flat head . You are correct the cam gear timing mark is at 12:00 you can also see the small scratch by the gear teeth as well as the mark on the ID of the gear. The mark on ID of the cam gear should line up with the small scratch in the face of the cam which is about 5:00 from your photo.
Ford used K R Wilson tools and they made a crank shaft gear puller as well as installation tool. If you want to remove the cam gear suggest drilling the ID of the gear next to the cam. This usually releases the press and allows the cam gear to be removed.

So are you saying that the cam gear is oriented incorrectly, as I believe?
There is a small scratch on the camshaft at the cam gear. (a little hard to see)
Is the tiny triangle shaped mark @ 5 o'clock a factory mark? I used it when I reinstalled the camshaft.
That made the valves closed at ignition point, but the intake is late according to the procedure in the FORD chassis repair manual. (checks cam position by flywheel teeth)
This picture is the position I used to reassemble the engine. I don't think it meets the "approximately three teeth before TDC ex." as it is described in the chassis manual. But it starts instantly, runs with 18" vacuum, and sounds so good after 47 years. The difference is that I never had to raise the distributor timing plate all the way up back then.

Bottom line for me is this, and tell me if I'm wrong. The maximum incorrect assembly of the cam gear to camshaft is 1 tooth. So it could be less. I stopped adjusting with both valves closed at TDC ready to intake. Will moving it one more tooth be worth the trouble?

I feel good!
thanks!

Your second photo has a red line on the cam face timing mark, it is just a scratch mark. The cam face timing mark should align with the cam gear inner timing mark. The cam gear outer mark should align with the crank gear timing mark the two timing marks will be adjacent to each other not 180 degrees apart. You have to remove the cam gear to get the marks aligned.

I believe that "carcrazy" is correct!

This should make it more clear. The red marks align the cam gear with the camshaft and the green marks align the camshaft with the crank gear.

TomO, I wish I could edit the pictures like that. That makes it crystal clear because I was already concerned (sure) that the engine shop incorrectly pressed the gear on the camshaft. (In 1977)
I can make that correction in an afternoon, But I don't have an afternoon this week. I will report back though because the adjustment from first picture to second picture made a lot of difference in the start and run. Now I just need Henrietta to idle like she used to.
But one more thing. The slot in the cam with your red dot is more aligned with a tooth than a valley. I think that means I can't get it perfect. Should I put the crank tooth with a dot, one valley before or one after the aligned tooth. I hope that makes sense.
Thank you all for you comments and great editing.
Brad
