Door hinges and end play

Postby gt350fme » Thu Jan 28, 2010 5:15 pm

Just wondering if anyone knows what would be the best I could hope for as far as DOOR END PLAY with new pins and bushings, when the door is slightly open and you can rock it up and down, I have replaced the bushings but not pins yet, still seems to loose to me, inch or so seems sloopy to me, I should replace the pins anyway but still I don't think this is going to be a porsche fit ? which has no end play at all, just checked.

Im doing body work on the doors now and I would like to get this right before paint.
Thanks

I have sold many GM door pins and bushings. There is a slight amount of play between the pin and bushing when new but it should not be that much. If I slide the bushing on the pin it is not a real tight fit but that's the way it is supposed to be, just enough clearance to allow everything to move freely. If you need any arts let me know. Unfortunately with the hinges welded on to the door and body there is not a lot of adjustment. The only way to do is is by "tweaking" the hinges. cjbiagi@yahoo.com

Clyde, I've been meaning to ask you this out of curiosity for several years now. You seem to be the man to ask about parts. My 1978 Fisher Body manual has a short section on h-body doors and it talks about replacing the hinges. Like you say, the hinges are welded to the doors and body. However, it states that the replacement hinges bolt to the door. it describes how to drill out the welds and shows the replacement hinge with countersunk bolts and uses an anchor plate inside the door with threaded holes to bolt to. Knowing that such a replacement hinge exists, would you be able to find a part number for it? The Manual gives part numbers for the bolts (two ea. 7667647 and one 8746511) and anchor plate (9840410) but no part number for the replacement hinges.
As an aside, it describes removing the body side of the hinge by cutting it apart with a torch (essentially destroying it) then after prep, tacking the replacement on and checking alignment prior to completely arc welding it to the body.

I don't think I would want a bolt on hinge on those doors.

There are a lot of part numbers to these hinges. Each hinge consists of 2 parts for a total of 8 different parts for both doors. That''s just the main "straps" as they are called. There are also a number of different anchor plates listed. There are also different numbers for HM, H07, & H27 cars. If you are seriously interested in something let me know and I'll try and research it more and see if I can locate what you need. Interestingly my manual does show the hinges being mounted with bolts.

You can buy new hinges and split them. Change the side that bolts to the door. That is usually the side that goes bad. If you find another way let us know what you do.

Couple little tricks of the trade I will share with you, but you must be very careful. First you can try a piece of 2x4 on a floor jack along the bottom edge of the door. Open the door slightly and place the board to push on a longer area than the saddle would do by itself near the rear of the door. This will bend the door frame inward at the top hinge area, BUT BE REAL CAREFUL because the door will get very close and maybe even touch the fender and could chip the paint, or you could roll the lower edge of the door so use your judgment. Another way is to place a big hammer in the lower hinge with the door open, then, with steady pressure force the door close. Not all the way, just until you feel a little movement. This will stretch the lower hinge and raise the door. This will most likely chip the paint in the hinge area. Last thing would be to drill out the spot welds in the factory hinges on the door and replace them with bolts. Then you can slot the holes and or shim the doors as needed.

Be very careful with whatever you do. These are proven methods I have used over the years sucessfully. Good luck. Mark Adams

There is a body tool made just for this purpose, it's a flat bar about 6 ft. long and loops over the body striker bolt and a bracket slips into the door striker. It allows you to almost close the door when in place and then lift up on the bar to pull the door up to the proper heigth, being careful to not pull up too much. It's usually the bottom hinge that gets pushed into the door frame. This bar just pulls the door frame back out. I was going to take a picture of the tool but my friend had lent it out to someone, and it isn't returned yet.

Zip.

Yes, Zip is right. I checked toolsusa.com and put door alignmnet in the search box. They have the one he is talking about for $54.

the best way to cure this is to shim between the door and the hinge. very simple fix and you can make shims in the size you need... should take you about 20 min. Owned alot of novas... by far the fastest way to fix it

I shall soon join the replacement hinge party.

Clyde if you have any updated info on the oe replacement parts please do let me know. You can email that to me at toddandchris1@cox.net.

I am also looking at doing much the same as above and making new pins and or bushings. The ss is a good plan also. I do like the replacement bolt on idea but looking at the hinge...removing that weld spot is going to be hell. The nice part however would be the adjustments offered. A larger backing plate to sandwich the sheet metal would work.

Todd, if you know exactly what parts you need let me know. As I mentioned, there are a lot of part numbers that make up these hinges. Each hinge is 2 different numbers, body side & door side. Then you have upper and lower RH & LH side. If you get to the point where you think you know what you need I'll see what I can do.

FWIW, I had to tweak the part of the hinge on the body of the car with a 3 lb hammer to take away the play and get it to line up right.

Not sure yet but thanks. Like someone above I'm a bit leaning towards some alternatives but maybe not....

Before I can really evaluate this thing I need to figure out how to remove the pin. She's not a-budgin' now! I'm guessing bull nose air chisel on the pointed end?
