Pat 12 gets a nose job

[Phil Waterman]

Hi All

My Pat 12 was missing the left inner panel that gives access to generator from under the left front fender and I need some photographs so I can fabricate a new one.

The truck is running great and the engine overheating problem seems to be solved. Now I'm working on the Driver Over Heating problem and trying to understand the cooling of the engine compartment. We have all seen pictures of Pat 11s & 12s operating in the desert without hood or upper side panels, but I'm coming to believe that this may actually make cab over heating worse not better. My logic for this is that with out all the panels in place the air from the fan is allowed to escape without blowing past the engine in the dog house and pushing the heat out and back under the cab.

Here are some photos of the Cab all repainted.

I spent an afternoon driving the truck around the back roads of town with the air temp in the mid 80sF/30C and the engine did NOT overheat either driving up long grades in 3rd gear or running along flat ground in 4th. I have fabricated new door hooks so that I can drive with the doors open to scoop air into the cab which helps with the driver over heating.

Hope somebody has a photo of the inner panel in their collection. I've searched through all the photos that Bob sent me a couple years ago and have not found a picture yet.

Cheers Phil

If I understand the problem correctly and the hole above the tyre in the first photo is filled by the panel you need to find/make, Bob does have the panel to be able to photograph and measure it. His best panel is already in the truck so not all sides are easily seen/photgraphed but the second or third best should supply views that can't be gotten of the best panel. As always on cab 11/12 it is a wrestle to get the panel in place. If you are fabricating a new one, you can put the holes in place to match your arch bar and fasteners so it should all fit "perfectly". You may also end up loosening or removing the headlight support bracket for installation clearance.

Hi Grant

You are describing the panel I need to replicate, I think.

On the Pat 13s this panel starts off being held in place with 3 or 4 1/4x20 bolts or flat head machine screws in 1942 to an end state of having a twist lock in 1945 so that this panel could be easily removed and more important easily reinstalled. The logic on the Pat 13s to make it easier to remove and instal is so that you could access the fan belt and the generator. As the generator had to be loosened to disengage the fan for fording I suspect that they realized they had to make it easier.

On the Pat 11 & 12 I would not be surprised to hear it is held in place by half dozen bolts and require the removal of 2 other parts to remove the panel. Working on the different Pattern # you gain a real appreciation of the improvements they were making to CMPs in response to field service problems.

I suspect that this panel is also needed to protect the fan, radiator, belt and generator from mud and water being splashed in from the front wheel.

Hi Phil

I will have pictures of the panel in place on mine by tonite. Also have a spare panel I can send you...... can mail from UPS mid of next week.....will include pictures of the spare at the same time.

And if my failing memore is correct there are NO access panel in the original of the cab 11.....will check on a few cab 12 I have just to verify. Now there is a panel on the driver's side near the fuel pump. ....and I may have a panel that was cut up by the previous owner.

It will be a nightmare to install now that the rest of the sheet metal is on place.

Well I am off with my camera..

None of those side panels have access panels like the right hand side.

Will post pics tonite..... and have a donor panel I can mail to you to use or replicate.

Hi Phil

The first series of pictures are actually my cab 11 side panel which I opted to replace with a better one. It would be a good model to reproduce from. It seems that all my cab 11 and cab 12 are the same configuration..... with no access door.

You will noticed that all my trucks are named from who I got them from.... also keeps them easily identified if you have any questions.

You may wish to incorporate them on your site for future reference.

I have included text on each one.

If any one as any questions, comments or if my information is incorrect fire away.

May have to post the pics in more than one email.

Cheers

Note to myself......

next time use larger print size for text
