Doors That Won't Shut Tight
A door that no longer pulls up flush, or needs a firm slam to latch, is one of the most common niggles on a hand-built Aceca, and, reassuringly, usually one of the easiest to put right. Here is why it happens and what the fix involves.
Why coachbuilt doors drift out of adjustment
The Aceca is built the old way: hand-formed aluminium panels over a superstructure of small steel tubes, on a tubular chassis. The doors use wooden (ash) frames beneath their aluminium skins, and they are substantial, carrying wind-down glass and an opening quarterlight. Two things follow:
- The wood moves. The ash frame in the door itself can flex and settle with age, humidity and use, affecting its fit in the steel-tube body structure.
- The doors are heavy, and the load goes through the hinges. All that glass and framing hangs off the hinges, which over decades lets the door drop a fraction, enough that it no longer meets the striker cleanly or sits flush in the aperture.
Add a body that can settle slightly on its subframes, and it is easy to see why an Aceca door that shut perfectly a few years ago now needs persuading.
What "won't shut tight" is usually telling you
Close the door slowly and watch what happens, it points to the cause:
- It reaches the aperture but the latch just misses, or will not pull the door in flush → the striker and latch engagement needs adjusting. This is the common, easy fix.
- The door has visibly dropped: the gap is tight at the top and wide at the bottom, or it catches the sill or pillar → the hinges, or the wood they are fixed to, need attention before the striker.
A door that only latches with a hearty slam, or springs back off the latch, is the classic symptom.
The fix, usually a straightforward adjustment
On most cars the cure is exactly an adjustment, often made at the door:
- Striker and latch: the striker on the body pillar adjusts in and out and up and down, and the latch mechanism sits inside the door behind the trim panel. Moving the striker so the door pulls up flush and latches with light effort, not a slam, cures a great many "won't shut tight" doors. It is a small job in the right hands. This page assumes the latch itself is sound and the door has moved; if the latch is the problem, the mechanism is covered on door latches and strikers.
- Hinges: if the door has dropped, the hinges come first, re-securing or shimming them, making sure their fixings bite into sound ash (tired screw holes in old wood are a common culprit), and occasionally renewing worn hinges or pins. Only once the door hangs correctly is the striker set.
The honest caveat: adjusting the striker alone to mask a dropped door is a band-aid, it forces the door to work against itself and rarely lasts. A good adjustment sets the door on its hinges first, then finesses the latch.
When it is more than an adjustment
Occasionally a stubborn door points to the ash frame, softened or moved wood in the door or the A-post that no longer holds the hinges or its shape. That is bodywork rather than a five-minute adjustment, and it is worth having assessed if adjustment does not hold. It is also exactly the sort of thing to check when buying, uneven door gaps and doors that will not shut cleanly can flag a tired or moved frame (what to look for when buying an Aceca).
Leave it to someone who knows these cars
Door fit on a coachbuilt aluminium-and-ash car is a feel job, and forcing it can crease an aluminium skin or strip a fixing in old wood. A marque specialist will have an Aceca's doors shutting sweetly quickly, which is the right way to have it done.
Common questions
Why won't my AC Aceca door shut properly?
The Aceca's heavy, coachbuilt ash-framed doors drop slightly over time as the wood settles and the hinges wear, so the door no longer meets the striker cleanly. It is usually cured by adjusting the striker and hinges.
Is a door that won't shut on an Aceca a serious problem?
Usually not. It is most often a straightforward striker or hinge adjustment. Only if the ash door frame or A-post has softened or moved does it become a bodywork job.
How is an AC Aceca door adjusted?
The striker on the body pillar adjusts in and out and up and down, and the latch sits behind the door trim panel; if the door has dropped, the hinges are re-secured or shimmed first, then the striker is set so the door pulls up flush without slamming.
Should I adjust the striker myself?
A small striker tweak is straightforward, but door fit on a hand-built aluminium-and-ash car is a feel job best left to a marque specialist, who will not risk creasing a skin or stripping a fixing in old wood.
