Technical Why Cant I Get This Door Hing Pin Out?

Discussion in 'Traditional Hot Rods' started by Mark Jenny, Jan 3, 2015.

  1. A hammer and drift pin is many times more likely to bend the sheet metal the hinge is attached to. An air hammer is a better choice.

    Heat is going to do the trick getting the pin out almost every time. It's also guaranteed to fuck up the paint 100% of the time. Here's the thing to consider though, if you heat carefully and protect surrounding areas you just need to repaint the hinge. If you twerk a hinge or supporting structure you multiplied the amount of work exponentially.

    Hard to say what you have there, but the flange should not be on the bottom.
    Do not try to drive the knerls thru the hinge. If someone installed the pin bottom side up and you drive it the other way you'll really be hating life.

    Joeycarpunk brings up a good point. The wax trick is pretty amazing, recently a customer of mine had some bulldozer pins froze solid not even hinting of coming out. He heat & beat in them for hours on end. Not wanting to be made fun of by his pals, he waited until they left then lit some candles on the suckers , let them melt down soaking with wax ..... Low & behold he is a believer every single one came out easy!

  3. I had the same problem with the sloted hinge screws on my A . Some pb blaster and a 10 dollar impact driver from harbour freight got them all knocked loose. Give that a try if you end up having to take the hinge off. Beats having to drill them out.

    I had the same issue on all my door pins. I had to grind off the tops, lots of heat(cautious to paint or pannels) and a air hammer. Good luck!!!

    I used the Bob Drake tool to get my pins out. Cranked the tool down after hitting it with PB Blaster and let it work overnight. Cranked it down some more the next day and finally got it out. The tool broke just as I was getting my last pin out but I did get them all out using that method over a period of a few days.

    Here's what my '31 coupe hinge pins looked like after we go them out. The top two, I'd already drilled out with a 12" long 1/4" bit for hing pin mirrors. Note that Model A original hinge pins are NOT 1/4" OD

    I thought it would be easy too but it took me 8 hours to do all four of my pins and hinge bolts it was a nightmare I drilled them then air hammered and I had to drill and tap all of my flat head counter sunk screws then had a hell of a time getting the plate out you want to knock them out from the bottom and out the top when drilling make sure you step the bit from small pilot to a larger hole but keep it strait it is hard to do with the door on the car then punch it out with some heat and a crayon heat it and sweat the crayon in like your sweating solder in a pipe then it will pop out You can use it for bolts too I know you may not want to heat it but sometimes you just have to. I whish I wasn't so cheap I should have just bought new hinges but I like driving my self insane with an air hammer

    This particular pin had no mushroom shape at the top of the pin...it was cut off flush with the top of the hinge...the bottom had a slight flange to it..not from pounding on it in the past, but a machined lip...a couple of my 6 hinges have this scenario, the others have standard mushroom tops as seen in your pic that you posted

    I have no clue 31 Vicky...I'll try and remember to take a shot of the other door , it has a hinge with the same type of pin...then 4 hinges have the mushroom shape
     
  27. Mark,
    I think that I saw a set at around 400.00. They're all custom made. nice but steep.

    It just depends on how they decided to to the chop. My 31 is chopped and has 3 hinges. The doors are light enough and the hinge area strong enough that two is fine.
