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!)

Hi to All! I`m a new member, recently retired !! My 1939 Ford Coupe Conv. Flathead has a wobble crankshaft pulley. I bought the car recently and that got by me not noticed. I removed the fan and center bolt . The pulley has play left and right and up and down. I tried a 2 jaw puller, but no luck, just tightened up. I tapped, then hit harder a block of wood on the backside, then tried a long steel punch. I can't move it. I haven't tried heat yet, as the engine is all painted for show., but I`m open to all suggestions. Is there a keyway where a key may be broken and lodged? Or could the pulley have worn a groove or burr into crank? I am hoping the pulley would wear hopefully being softer steel. Ive run out of ideas and any help or experience would be REALLY appreciated. Thank You very much.

If you have room to allow use of it, you can try using a slide hammer type of puller to remove the pulley. You may have to remove the grille and its supporting structure to provide adequate space to work.

Thanks car crazy! I`ll look into that. The thing that puzzles me is I can move it left and right back and forth and same top and bottom , so it doesn`t appear to be "stuck" as much as hung up on something??

I would not beat on it to much you might mess up the thrust bearing on the crankshaft and heat would kill your front seal go easy my friend. something tells me the key way is the problem I would try truning it back and forth while pullimg it off the might be A sweet spot

Thanks DanD32! I like your suggestion of turning back and forth while pulling. I have also thought of mounting a thick solid bar of steel left and right using the fan holes, and moving back and forth to try and get by the hangup. Thanks A lot for your advice and knowledge.

You should not need a puller to remove the pulley.

I believe that you have to remove the radiator on order to get enough clearance to remove the pulley. You may also have to jack up the front of the engine.

Don't wobble it side to side or up and down too much, you will ruin the front seal and then have to pull the oil pan to replace it.

Hi Tom, The Bolt & washer came out reasonably easy. Used breaker bar and thin socket. The pulley has roughly 4 1/2-5 inch clearance to radiator, so Im trying puller first. Today I squirted Blaster in the front snout and 1/8" space I see behind pulley. I think Dan is correct that its a key keyway problem because of the pulley play. the puller just tightens up and there's no moving it, I even put a short pipe on wrench but to no avail. Tomorrow I'm going to look for the "sweet spot" that Dan mentioned above, moving the pulley sideways while puller attached. Beyond that, Im at a loss, and need any advice I can get. At that point should I try to cut it off? or would it be impossible not to damage the snout? Any other thoughts?? THANKS, AL

I think the pulley wobbling that I noticed while engine running has already impacted the front seal, as there is a small oil leak.

AS a last resort I would use A small die grinder or dremel like tool with A cut off wheel and try to split it in two using the key way slot for one of my cut line's go very slow checking all the time not to hit the crank leave a 1/32 or so then split it with a chisel or a screwdriver that you use for one ( every garage has one) lol ! Please be careful and Good Luck !!
