Carrier Fan failures

[Michael R.]

Substituting a flat washer for other components, not using updated locking plate leading to incorrect positioning, installing on manifold where the locating shoulders are cracked or missing. Failing to check the nut assembly.

[kosbie]

Does anyone have a source for the locking plates?

Thank you gentlemen for your interesting replys.
I have done a little research: (I'm an amateur)
Anyhow, I have 7 flathead Ford V8 inlet manifolds. see photos.
I have numbered them 1 through to 7
1,2,3, have carb mounting flanges that look like they would suit 97 Strombergs?
4 is a special unit. Part# C29SR 6520. More later.
5,6,7, have the Holley style carb mounting flange. For those not sure, the carb stud arrangement means all the carbs fit all the manifolds.
1,4,5 are cast iron, the rest being alloy.
1,2,3,7 have the blanked off forward oil filler hole.
6 is from a post war 8BA.
1,5, I cant find a part number, both being similar except 5 lacks the forward oil filler hole.
1 is drilled for positive crankcase ventilation 5 is not.

Ford part numbers, (for those that don't know)
Very basically Ford uses a 4 digit number to identify a basic part.
The inlet manifold for a 4 cylinder tractor made in England, or for a flathead v8 made in Canada is 6520. The thing that differentiates them is the prefix and then the suffix. Example is a Cover, C11A-6520-C (my examples:2,3,7)
There is a system to this: C=made in Canada. 1= 194(1) design. (If you want more check it out)
Anyhow Back to Carriers.
I have been checking out the various engine models in carriers and...........It's complicated.
There are 3 basic engine types (as per origin) American, British, and Canadian (in alphabetical order)
With the British built carriers they used pure British engines, American engines, and combinations of components. Of the British built engines ( 79E 6004) they came with the following suffixes:CS,DS, FS,GS, and HS.
These denote different combinations and applications, the last 2 reworked for Loyd carriers.

Anyhow:
The 1941 Canadian carrier parts list shows a Cover, C11A 6520-B cast iron. I dont know what they look like.These must be fairly common still, in carriers. Do they break?
THe March 1945 British Chilwell (Carrier parts list)63/76 lists a:
Cover C11A-6520-C I have 3 of these (2,3,and 7) They have 2 big ribs running to the front flange. Do these break?
As it happens I have the C29SR manifold that I previously mentioned. It is from a Lynx and is a very robust looking manifold. Was made to support a massive (lets do some arc welding) 90 amp generator. It has the ability to have suplimentary support brackets as was the case with the big generator. This would (hopefully) limit the failures to all the components forward of the manifold (cover)
Can anyone come up with a part number for my two other cast iron manifolds (1, and 5)
I have put up pictures of the big generator from the
Lynx along with a std. Canadian generator/ fan extension to show the comparison along with one of the un identified manifold and the C29SR.
Thank you and stay safe.

We had our one go through the radiator because the front of the cast iron inlet manifold snapped off. We have since remedied this by fitting a manifold which takes the large 12V generator and support the generator at the back using the bolts in the manifold. Plus we have now installed mesh between the fan and the radiator to help protect the radiator when we did that upgrade.

Both of my Belgian Army Loyds which came from the firing range had locally fabricated Dynamo supports which bolted to the cylinderheads under the main body of the Dynamo with a strap over the top to hold down the Dynamo. So I presume in the immediate post war period they had manifold failure problems too.

Hi Alistair, that's a serious looking mount. Would it have held a bigger than std generator? It's a bit hard to tell from the picture.

David, Was your (12volt) manifold the same as my C29SR manifold?
