Is that not where the gear-lever comes through?

Hey mr wolf are you certain that is what it is ... I’m asking for a mate who’s bought the bulkhead @steve_overland on Insta.

As DAZ said for the position looks like the hole for the gear levers


As display in the workshop manual...



Cheers and good luck Eduardo

It’s not the gear selectors , they sit forward (technically it’s towards the rear of the truck ) of that section of the bulkhead.

It’s not to do with A/C either

I’ve just removed the heater matrix from a 2011 a/c fitted defender and the hole isn’t cut out

Aha, the a/c drain is the small round hole nearer the centreline, visible in the photo above.

In which case I have no idea what the big hole is for, but it's definitiely not the levers.

I'm intrigued now! Not because I have one of these in a Tdi, but because that's a pretty big hole, and the accumulated wisdom of Defender2.net hasn't pinpointed it yet - which is pretty unusual.

I'll have to 'follow' this now to satisfy my curiosity.

Also intersting to notice just how much soundproofing is on that bulkhead in comparison to the Tdi. Donald

Wondering whether it might be something to do with a power take off? Not sure if Pumas had these but maybe if the bulkhead was from an ex utility spec vehicle - does your mate know the donor vehicle?

The only PTO options on a TDCi are those which pick up on the LT230 in the same way as earlier vehicles, so it won't be PTO related.

On a fully-assembled vehicle the top of that hole will be slap bang under the heater unit and completely inaccessible, whether RHD or LHD it makes no difference. It really is a bit of a mystery, especially as some clearly have the hole punched out and others just have a flat unpunched area.

The size suggests an access hole. It is possible that it is an artefact like the unused "gearbox mounting" on the crossmember below the MT82, which I think only exists because the MT82 CAD pack says there should be a mounting there. Perhaps it similarly says there should be a hole in the floorpan above the MT82 to allow access to the clutch pipework.

I hope that we can bottom this out, it is fascinating!

What age is the bulkhead with the hole? Is it an early one?

It was introduced with the defenders around 1990 so to lower weight to enhance high speed cornering
