Pat 12 gets a nose job

[Phil Waterman]

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..

Cheers

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

.....so far so good.

Picture shows as 2.0 MB on my system

Let's see if the MLU system will accept it.

Hi Bob and everybody else who responded to the Need Picture of Left Front Engine Shield

Well I finally got around to fabricating the Left Splash Shield.

Here it is installed, note I did some field modification reducing the number of bolts that have to be removed to access the generator. It now has only three bolts to remove or install.

See next post for dimensions.

Next two photos show the unit being prep for spot welding.

Have not driven the truck much since installing but it noticeably reduces the amount of fan air coming out under the fender. But it also appears to increase the air pressure in the engine box so that any seem or joint on the dog house aimed at the driver now produces a stream of hot air. Spent the morning sealing and closing those gaps up.

My thanks for all the photos provided, once it was clear what the part looked like it was not difficult to cut and fit cardboard template. Once that was done then the steel was easy.

Hi

Hope these panel templates, with more readable dimension for the panels to fabricate the splash shield, are more helpful

W Pat 12 Splash Shield Side.jpg

Note the 1" holes are meant to over lay the side panel mounting bolts, with only 2 of them being used to attach the panel. The tap toward the front is bolted to the radiator frame using a carriage bolt with a thin nut to capture the bolt to the radiator frame which is them over laid by the tap with large washer and nut.

W Pat 12 Splash Shield bottom.jpg

On the bottom panel the two 1" holes over lay the frame rail rivets. This edge is covered with some anti squeaking material to allow for cab movement.

W Pat 12 Splash Shield Front.jpeg

Front of the shield just completes the enclosure.

As mentioned having both Splash Shields in place forces the air from the fan to flow through the engine dog house without all the air from the fan being exhausted into the wheel wells. Did some testing over the weekend in 80F air temp on long 10%+ grades down in second gear to see if it improves engine cooling or not. No clear difference.

Cheers Phil
