Angry door hinge pin install

Car: 1978 Porsche Targa

Problem: Can't get new door hinge pins to go into hinges with new bushings.

I searched some old files and one guy said that the pins are an extremely tight fit
(no *****) and that the bushings need to be lightly machined. Is this true? Seems ridiculous to me that one new part (bushings) would have to be machined to fit another new part (pin).

Well, my door is off and one new pin is hammered half way into the hinge and that's as far as it wants to go. Did I mention that the hinge is really hard to move now? HELLLLLP!

He was right....pins and bushings need to be sized to work properly.

Kevin, thanks for the confirmation.
The bushing flange also needs to be sized to the other hinge half.
Still amazed that these parts didn't come already machined to fit each other.
Fine German engineering or rich mans' volkswagon, the jury is still out.

Nice thread subject. You have to get an 8 mm reamer and ream the bushings to fit. You also have to fit the bushing flange. The did it that way so you would have a nice no slop door. If you have the tools and the knowhow it is no problem and you will be happy with the door

This is actually quite common for replacement parts, and makes sense. It's impossible to know ahead of time how much wear a piece would have, so you drive in a bushing, ream it to size, which guarantees a perfect fit without having to stock umpteen different possible oversizes, ala cranka and rod bearings.

Well Thom, if your going to bring logic into this then of course that makes sense.
I've owned old American cars for so long I forgot to stop thinking like a caveman.
Jury says 'fine german engineering'.
