tin_indian 10 Posted April 27, 2014 Hmmm...Thanks, Tin Indian. I think that would completely compress the coil springs inside, right? Then back off for slot alignment, just giving the springs the least bit of rebound/compression as steering inputs and road shocks are transmitted. It's a funny old system. And funny that it isn't covered in the shop manual. The picture of your 54 reminded me of the 51 Ambulance, body by Meteor(?-hazy on that) I got back in '79 or '80, on its very last legs, as an engine donor for my 53. And telling you that reminded me of the 57 Pontiac hearse I bought around then, in the hope that its Hydramatic would replace mine. Big disappointment - little in common but the name.Is that vertical chrome ahead of the rear wheel a simulated air intake, like Caddys of the era?In my '49 - '54 shop manual it has a blurry photocopy of the centerlink that's a cutaway. It says, (with an arrow pointing at the end cap) "Adjust end plug by turning down tight and backing off to nearest cotter pin hole" When I had my centerlink disassembled to clean and re-grease, I remember noticing the springs looked heavier than a valve spring. I highly doubt turning the plug in would even begin to compress it. You'd have to really crank it.The vertical chrome is to cover the section of the front of the rear fender that was cut off. There was a rounded front to the fender. To accommodate a straight vertical edged rear door, the fender was chopped and a chrome piece was fabricated to cover the raw end.Heres a shot of one side of the centerlink guts. Note how heavy the coil spring is? Share this post Link to post Share on other sites
Tinindian 1,105 Posted April 27, 2014 There is a special screwdriver that exactly flits the slot. On my car I tighten it down as tight as I can using a 1/2 inch ratchet (approx. 60 ft/lbs) and then back off to insert the cotter pin. You have no idea of the road force shock that is put on those springs and seats when your wheel hits a bump, pot hole or the wheel drops into a rut. Adjusted right and lubricated those pieces will last 500,000 miles. Share this post Link to post Share on other sites
stelor 10 Posted April 28, 2014 Thanks again, Tin Indian. I should have taken a closer look at the manual. Great pictures of your project. Wow, a lot of work to this play, isn't there? Some of the sheet metal and heavier metal work you had to do seems painfully familiar to me for some reason. My 57 hearse furnished an electric wiper motor for my 53, in an easy installation. It still uses the cables to run the pivots, and they're looser than they should be - another situation where I'm tempted to say the manual doesn't give adjustment instructions. But I'll recheck before saying that. Share this post Link to post Share on other sites
stelor 10 Posted April 28, 2014 My thanks to you, too, Tinindian. Years ago, I flattened the shaft of a 3/8" extension for use as an adjusting tool. It has since gone the way of all the earth, and was not among the goods and effects present on our trip south. I improvised using the tire iron. "Some fun, huh, Bambi?" When the apprentice asked the old pro for the torque spec, O.P answered, "As tight as you can get it, plus a quarter turn." Share this post Link to post Share on other sites

Tinindian 1,105 Posted April 29, 2014 At least one full turn. It needs to be tight to be right. Share this post Link to post Share on other sites

stelor 10 Posted May 23, 2014 Hello, Charles, and thank you. I got my wipers sorted out - I used the muddle through, trial and error, take a stab in the dark, if at first you don't succeed, try, try again method that has served me so well, so long. I've admired your impressive (understatement) Pontiac, having seen your posts somewhere. Love the spoke wheel covers. Share this post Link to post Share on other sites
pontiac1953 149 Posted May 23, 2014 hi stelor, i went out to my 53 (not much room around the car in the garage) and tried to take some pictures with my sony digital camera, lol, the air conditioning hoses up inside the dash kept me from getting good pictures. i am glad to read that you sorted it all out. thanks for your opinion of my olds/pontiac wire wheel hubcaps, that was a fun project, i ended up doing two more sets of four for other people, and one for a friend's man cave wall decoration. let me know if you have any other 1953 pontiac needs. charles coker, 1953 pontiac tech advisor.

stelor 10 Posted May 24, 2014 Thanks again, Charles. I appreciate the effort you made, including an advanced application of contortional gymnastics, to get those pictures. You da man. And I relate well to the not much room thing - those two doors take a lot of it to get them open far enough for inside work. I removed one defroster duct, after removing the dash speaker, after removing the glove box, and then I could get my hand (singular - not that I don't have two) in there. Needed light, but the light kept getting knocked out of focus, speaking of which, working at that distance I have to peer over the glasses. The pull-up cable goes on one drum, and the pull-down cable on the other, for each wiper. Simple, once you know how. I suppose that's in a body manual or a wiper supplier manual somewhere.I found another use for those rear fender emblems. I used one of mine as a mold, melted aluminum rod into it, and for a second one, solder, to make a head for my grille center. Sandwiched it between plexiglass circles, put a light behind it, and get along pretty OK until a correct one shows up in my price range of, well, low.

DABJR 1 Posted September 13, 2017 (edited) Picked this 51 up a few months back,I guess I will have to get a pro mech.to get it running right. It's a 6cyl., 3 on the tree.It has about 111 to 115 lbs of compression in the cylinders,all plugs out . I really cant find out what normal compression is in the 239...has a light to medium noise in the middle of the eng. carb side.Starts idles, doesn't rev good , most plugs turn black . I might be off when I brought the no.1 cyl. to top dead center..guessing which plug it pointed to and then went counter clock wise with the wiring.

Bloo 978 Posted September 13, 2017 Compression is ok if it is like that on all cylinders. Most, maybe all flathead Pontiac sixes have a piece of pipe inside the intake manifold that can rust through and let exhaust from the heat riser into the intake. It is directly under the carburetor if you have it. I would look for holes in there. Welcome! 1 Share this post Link to post Share on other sites
DABJR 1 Posted July 7, 2018 Thanks for your quick response.Sorry if I posted too many pics., but I thought some one else could compare and reference with them .My heat ex changer was rusted shut.....Thank you.... I changed a lot of gaskets along with some broken exhaust bolts.I used every thing to break the shaft loose and I think the torch and wax was best.With a pipe wrench,slowly,don't get to discouraged.Stopped the noise but it was fatigued point spring that was cracked and would cut out when reved up, and smoked..Feels good to overcome different problems,even thought I'm not a good mec. It's ready to drive.100,000 mi. and very little smoke now. Ins. will be super cheap...$175 a year,full coverage for $5000 RIG. 1 Share this post Link to post Share on other sites
Randiego 100 Posted September 2, 2018 Gents, Since this is a little used site, I was wondering if there was another site for the "Flatheads" (other than the POCI Early Times Division) that one can go to for help in parts and service for the 1930s Pontiacs? You show a lot of 40-50s cars and with little use of this site, it would be helpful if one could find another source for help. Randy Share this post Link to post Share on other sites
