    Default Re-Spring a R17 Door Hinge?

    Re-Spring a R17 Door Hinge?
    I'm in the motions of restoring a passenger side door and was wondering how can I repair the spring latch on the hinge. Anyone have ideas/experience?
    The drivers side is also in need too.
    There are just some spring sections still there but presume they have broken bits off.
    Cheers

    It will be a tricky operation to refurbish the door stays. Attached is a pic of a “typical” 1970's Renault door stay, in this case a Renault 12 lower door hinge and stay, the 12/15/17 all share similar design attributes.

    Effectively the plastic roller on the door presses against the spring steel plate on the hinge, with the high density rubber extrusion between the hinge and spring steel plate providing the stay. What happens is the spring steel plate fatigues and fractures, then the rubber falls out leaving the door with no stay, and in extreme cases the door (if the plastic rollers deteriorate) can then open too far with the back edge of the mudguard then dinting the door.

    It will be very tricky to replace the spring steel plate on the bottom hinge. The hinge to pillar retaining bolts in the steel hinge are interference fit, so a press would be required to press them out. Then good spring steel plates would be needed to replace them, but were never sold separately.

    Likely the best bet for replacement would be to look for NOS, I'd be guessing there must be some somewhere gathering dust, with no knowledge of what model they are meant for. There have been three part numbers used for the 15/17, for the RHS; 77 00 530 800, 77 00 577 250, then 77 00 579 303. For the LHS 77 00 530 862, 77 00 577 246, then 77 00 579 305. The earliest numbers are superseded by the latest numbers, each likely an improved design of the earlier part.

    Adapting a friction or roller type rod type stay from another vehicle/model would be tricky, but not out of the question. Then you have to think about reinforcement of the pillar and door, length of the check strap etc.

    Thanks Simon.
    Going by your picture I might be able to mock up something. As you know the bolts tap out.
    I have a what's left of the spring. If I can make up something similar we could be in business.
    Is the round pin steel or hard nylon and what diameter mm is it? If you don't mind measuring for me?
    The pin should be pressed in later, as you said.
    The pic attached shows where mine is broken and missing the pin. The rest of the parts are there on the other section of hinge.

    The round "pin" is high density rubber, 11mm in diameter.
