MK-II* Carrier trivia question
 

Many, if not all factory original engine cover ventilation screens from the UC NO2 MKII* have a small framed rectangular shape opening.

A similar opening is not observed in the MK-I* or UC-2 series carriers.

Trivia question:
What is the opening for? :teach:

Adaptor, Grater, Cheese, Type 1, Mk.IV ?

.... “ and their off . . .”
 

I do enjoy MLU Forum over the FB version.... it has a more intimate feeling developed over years of friendship and supporting each other in our illnesses.

I have wondered! Although it's never kept me awake....Till now. I await the answer with trepidation. Ron

I await the answer with Parmesan.

Wrap your pasties in foil and leave them on the grate until lunch time?

But seriously, is it not for exhaust air from the cooling system; in from the front and out through the top. Without this the fan would have nowhere to vent the hot air from the radiator and the cooling system would not function efficiently. All tracked AFVs that I can think of have a similar system.

When I worked with Challenger 2 Recovery Vehicles the hot air outlets were a very popular place to dry off after recovering things from water!

Tom you missed the point! it's not the actual grill that is in question. It's the formed rectangular hole within the grill. :confused Ron

If you look down to the hull floor through the opening I believe you will see a hull drain fitting. If I remember correctly, on my (now someone else's) carrier, this is where the shaft came through to open and close the drain.

Not so Perry! The 'T' handle drain rod has its own location. Ron

It appears my memory is not that good after all!

I now see the drain shaft in the first post.

Grate thoughts ...
 

. . a few are kinda cheesy though.

Two framed openings within the engine ventilation screen of the MK-II. The round hole with brass grommet frame allows the rear hull drain seal assembly opening/closing rod to pass through. The MK-II* rear hull drain is unlike that found on the MK-I* series of three models of carriers.

Then there is that pesky rectangular shaped opening.

Was it to let one fit a wrench in on the nut for the bolt in line with the cutout?

I can't see anything in easy reach of a spanner! The only things that line up under that aperture are, the clutch rod pivot and the bush that the gear change rod runs through. If dripping oil onto those components were the case, then it could easily be done through the diamond mesh without the need of the rectangular hole.......I dunno!?? Ron

Is it for access to the screw type fuel change over valve?
In A MkIIIw the screen has a hinged section which is held shut with a spring and a hooked catch like is found on early race car bonnets (hoods) and 3 inch mortars.

I'll chip in again Lynn. The MK2 has a change over lever between the driver and gunner seats. Ron

I know I know I know......but will see if anyone else gets it. :teach: :thup2:

Ron Pier... it kept me awake, on and off over some seven years.
Was it a left-over from an early stowage design? Did a portion of the BREN tripod some how touch that area? If the PIAT or Boys was mounted on the engine deck, did a portion of either somehow need clearance?

What about the change from the smaller engine ventilation screen of the MK-I* and UC-2 made of copper wire? The screens are not interchangeable between the MK-I* and the MK-II*, could that be a clue?

Is it anything to do with the oil filter? Mine hasn't got one, so I can't check it.

Otherwise I haven't got a clue! Ron

Oil filter sits on the drivers side roughly mid engine bay.

I know there was a canvas winter cover that went over that grill for cold weather operations . Does it have something to do with that ?

Quite right! And you can see it through the hole in question in the second picture of the original post. Ron

Top of the fitting has the hose coming out of the side, from memory nothing comes out of the top... need to dig my filter housing out of storage as you have me thinking now !!

I Know, I Know, I know too! :) Ron

Donald Rumsfeld once said: "as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns; the ones we don’t know we don’t know.”

I think that applies to this thread. Some people Know. Some people Don't Know. And lots of people Know they Don't Know, and others Don't Know they Don't Know. :bang:

I sorta think I Know where I fit in? :confused Or do I? I Dunno!

It leaves me pondering the unknown. How long should I let the thread run before revealing what I think I know? Does anyone know? :drunk:

Don’t hold us all Ronson anymore :giveup

The word is ‘ransom’.

It may be a relief for some when the details are revealed.

So.... What about the rest of us? :giveup :giveup :giveup :giveup

Oh! Oh! Oh!

Was "Ronson" a clue, or a typo?

Or was he just maintaining the lighter mood? :doh:
