On my naa 134 motor my dip stick is 11" long to the collar. The oil pan is 3 1/4 deep to the base of the block .I put 4 qt of oil in the dip stick is on full this is with new filter also. I think 6 qt is what it should hold . is the dip stick to long? or is the pan to short?
 
As per the NAA owners manual it holds 5 qt plus 1 for the oil filter so yes 6 qt.s is right if your changing the filter. So yes you may have the wrong dip stick which is not good. Had that problem years ago with my 841 and that in turn cause the engine to have to be rebuilt
 

I thought all Ford tractor engines 8N through 64 took 5 qts. including filter replacement oil. Am I wrong?
 
The dip stick on my 801 diesel is 11.25 inches long to the collar and the parts book shows it as the same part.

But with that said I believe the pans and stick are the same but the tubes might be differant.

At any rate the motor holds 5 qts with the oil filter. Remove the oil and filter. Install a new filter and 5 qts oil. Run tractor to fill filter and put a mark on the stick where full should be.

Right out of the true as in not a reprint owners manual page 6 capacities Engine oil pan 5qts. with filter add extra qt. and that is word for word from the manual
 
Sorry that info is WRONG you most have a very poor brand of manual there since the 1954 NAA owners manual on page 6 says it takes 5qts for the oil pan and ADD 1 qt for the filter so 6 total. By the way this is not a reprint manual it is the one you got with the tractor when new
 
Upon reflection, the 8Ns hold 6 qts with filter, as per the owners manual. The 172s closer to 5 1/2 with filter (owners manual says 5 with filter but this is not quite enough to fill to the full mark).

I usually let my engines drain overnight after pulliig the plug at operating temperature. I always remove the canister on the 8Ns for cleaninig, draining all of the oil in the process.

So Dean a question for you. The NAA owners manual I have says 5 qts plus 1 qt for the filter so is this 1954 NAA manual incorrect or what. Note I say 1954 manual since it is not a reprint
 
Funny here is the cap. page out of the 1954 NAA not reprint owners manual I have. Your manual doesn't even look close to the manual I have as for the front cover. My manual cover page is Red

We may both be right.

I looked around to find a answer. I noticed that your book is 1954 and mine is first run 1952 when the tractors first came out.

In 1952 at serial #18094 they changed the tube but left the stick and pan the same. It went from 10.47 inches long to 11.25 inches long. This in turn would raise the stick 0.78 inches.
So more oil would be needed to read full on the stick. I wonder if .78 inches works out to one quart.

Ford may have found out 5 qts was not cutting it and changed it to 6 qts.

The question I now have is why the 600 to 801 manual says 5 qts but I am not able to access that info right now.
Like Dean my 801 is suppose to hold 5 qts but I believe 5.5 is more about right.
 
THANK YOU JOHN,OLD ,LARRY AND DEAN.I AM GOING TO PUT 6 QT IN AND MARK THE DIP STICK. THANKS FOR TAKING THE TIME TO WRIGHT.
 
yeah.. if buying by the quart I grab a 5qt jug plus a spare qiurt when I do a 4 cyl oil change. I usually dump in all 6 and go.. it may be a hair out of the crosshatch.. but has never caused an issue that I know of..
 
Don't know as I've never had an NAA manual.

My reprint of the original Ford hundred series manual lists crankcase capacity with filter as five quarts but, as I said, all four of my 172s take about 5 1/2 quarts to bring the level to the full line.
 
Bottom line is that engine oil level is not an exact science nor need it be. The "operating range" crosshatch encompasses about a quart.

There were two owners manuals issued for the NAA. Yours is the first one published in 1952, form number T400-K52. The second one with the red cover is form number SE5943, published in 1954. I've read them both cover to cover and the red one is a better manual. Explanations are more clear and the writing is easier to follow.

I just checked the oil capacity specs in both books and the red 1954 edition does add an additional quart over the first manual with the tan cover.

The real cause of the oil crisis is that all the oil is in Texas and all the dipsticks are in Washington DC :lol:
 
Guess I should look in my 601/801 manual since the owners manual that came with them new covered both series tractors. Again this one is not a reprint so I will look at it later and see what it says
 

If you are in hilly country as I am and you add only 5 QTS. you'll be looking at "0" oil pressure on some of the down hills. I pour in 6 QTS. on an oil/filter change.
