Door mounted spare latch mechanism..help.

[HingsingM37]

Can somebody post a pic of the inside cab lever release mechanism for the B1 door mounted spare? I bought one in pieces and I am not sure of the assembly sequence. Does the lever face forward, backward? How is it meant to operate?

The release lever faces to the rear, lifting it rotates the latch shaft unlocking the tire carrier arm.

THanks Carter!!!!!!!!!

The latch is installed, the spare tire carrier is on, the spare is on it and it works! That is a nice dead lift putting the tire on that arm.
I must have open and closed it 50 times in amazement I recall about three years ago saying "someday I will be at the point where I will install that cool spare rack".
I will post a pic link ASAP

GOOD MORNING ALL, I HAVE A "NEW" NUBBIES STILL ON THE SIDE WALLS, SPARE ON A RIM. I SEE SOME MOUNTED INSIDE THE BED AND SOME ON THE DOOR. QUESTIONS: DOES THE DOOR MOUNTED TIRE INTERFERE WITH THE DOOR SWING? IS THE DOOR STRONG ENOUGH TO CARRY THE SPARE W/O CAUSING DAMAGE OVER THE LONG RUN?
I SEEM TO FAVOR THE BED MOUNTED SPARE, BUT MAY NOT WANT TO GIVE UP CARGO SPACE. WHATS THE ADVANTABGES AND DISADVANTAGES OF BOTH? WHERE CAN I GET THE HARDWARE TO MOUNT THE SPARE?? THANKS BOB

Hi Bob,
The door mounted spare is a bit of a misnomer, as it is actually mounted to the door post. It swings open, then you open the door. The M37B1 trucks had this type. There are reinforcements from the dash to the door post, so it is more than meets the eye. The early trucks used the bed mounted spare. The door mounted spare hardware is a bit hard to find (complete) but they are out there.

There is also a 1/2 inch spacer block that goes on the left front and rear springs to add a little height. This compensates for the extra load the spare puts on the left side.

GOOD MORNING, OK I THINK I WILL GO WITH THE BED MOUNTED SPARE. I SEE BED MOUNTING HARDWARE FROM SNAKE RIVER, CAN IT BE MOUNTED AGAINST THE FRONT OF THE BED??
THANKS
BOB

4 bolts hold it in place-it sits in the passenger side front corner of the bed. It might just be me but I inspected mine (not yet installed) and those mounting bolts appear to be pretty small for holding such a large item.

The weight shouldn't be a problem. The mount bar is pretty stout and will support the weight easily. The bar is secured with two bolts to the bed floor and two more to the top rail of the front panel, which effectively transfers the weight of the spare tire to the frame of the truck. In other words, "it ain't gonna go nowhere."

If that thing ever broke loose, first there be nothing left of the truck, second, you'd probably see the spare still on the bracket, standing up right along side the road like nothing happened! I bought mine from MWM - John has the correct bracket, spinner, and the cast mounting plate.

Thanks Carter for posting this, it answered a question I might have posted. Now where can I get the hair pin spring shown? As mine is missing and my handle is currently pointed forward.

I bought the inside latch and spring from Memphis Equipment, I already had all the outside stuff I found at a local fire company's M37 graveyard but the latch with spring were long gone.



I found the in cab reinforcing bracket at the graveyard also so I didn't need to get it from Memphis and I made a sketch of it in case anyone else needed an idea what it looked like.
I know the drawing states that it fits an M37 but that is for retrofit only and not as orig. issued.
