oil pressure in my 1953 ford jubilee

ejensen

Well-known Member
after installing new rod, .001 undersize bearings, and standard mains the oil pressure has made an improvement. Best way , I know is to totally rebuild the engine.
However oil pressure goes to the top of the gauge, 50lbs, when first starting. I do not know the range on the original gauge. Gauge in the tractor looks like it came with the tractor. Checked oil pressure with another gauge and results are the same.
50 lbs first starting, pins the gauge, after warm runs 25-30 at idle , closer to 25, and at 1200 rpm runs at 40 lbs oil pressure. Engine sounds good. Tractor gets limited use. Have a loader on it which I really like. Would appreciate what others think about the present oil pressure on my tractor.
 
a tight red tiger with cold oil at throttle can peg 60 psi, relief open..e tc.

while 25 hot idle is showing wear.. there's lotsa life left in there.

45 running psi is 'good'
 
you're good.
And now that you've been in there, you have the peace of mind
of knowing that things are assembled correctly and tight.
Put it to work.
 
Cheap fix.
Nice job.
If your rod journals were worn .001 and your bearings .003 you tightened it up by .004
That is a lot. Mains by a couple thou too.
What readings were you getting before?
 
Ultradog,
I used plastigage to check the clearance on the rods. Clearance was withing specifications. Unable to get undersize in .001 for the mains so used standard. The engine, in my opinion, like a lot of older tractor engines has only 3 mains. Oil pressure prior to the work I did was 10 - 15 lbs when warm and 25 -30 when cold.
 
NNP,

You are so correct. I use it a lot for moving things at my place. Just recently used the loader to load large wood I cut from a very large douglas fir tree. Loaded the blocks on my 1966 ford F 100 pick up
 
Soundguy,
Present oil gauge goes up to 50 lbs. Do not know if this is the original gauge. Looks old so imagine it is the original gauge. Plus the oil line to the gauge is large like many of the other farm tractors of this vintage I have repaired. The 45 lbs is at 1200 rpm. Goes higher when I increase the engine speed to PTO speed. I really like my ford jubilee. A great old tractor.
 
Ericib,
That is interesting. I do not know what puts hard use on a farm tractor. I would think plowing day after day and other field work which requires full power from the tractor engine, poor maintenance, no oil changes, no filter changes, and poor fuel.
I know the history of the jubilee I have. It was purchased on the farm next door to our place. The farm had a farmall Super C IHC, and a TD6 IHC crawler.Heavy plowing was completed with the TD6 pulling a 16 inch 3 bottom tag along plow. Field cutting was completed with the Super C. The Jubilee pulled a Allis Chalmers piece of equipment which cut field grass and through a series of blades the grass what cut into pieces which went into a silage pit. The AC machine was powered with a Model B AC tractor engine. My knowledge of this equipment was through. I worked on the farm as a hired hand during the summer for many years. The person in charge was also a hired hand and he always did oil , filter changes regularly. My job was to follow his directions and help with the equipment maintenance,run the
TD6 in the silage pit compressing the cut grass from the AC machine. It was hauled in a 1.5 ton IH
C which had a dump. The AC machine had a chute, the dump truck was behind the machine and the cut grass was blown out the chute of the AC machine into the dump truck.
The only thing the Jubilee did was pull the AC machine during the silage making process. The Super C did the cutting of grass in other fields which was baled into hay. Many years of light duty may explain the good condition of the jubilee I have. Unable to provide the oorrect name of the AC piece of equipment. The forum always make me realize that our country has many
people with exceptional knowledge about farm equipment. A great place for me to communicate,learn, and share experiences with other people like me who have interest in farm equipment.
my website , einarjensen.com , shows tractors my wife and I have repaired, restored, during the last 40 years.
 

I think my guage is original too.
I just went out and started it.
1st photo: startup at moderate idle.
2nd photo: 600-800 RPM

I'm pretty sure that my oil pump pickup tube is loose and I'm still waiting for a pan gasket.

"Douglas fir" . . . Sounds like you might be in B.C.

After a little test of time and components . . . I'm really pleased with my tractor too -- noisy vane pump though.

TallT,
Your Jubilee has great oil pressure. Noticed that your oil pressure gauge goes to 80 lbs. Mine goes to 50lbs.
Our place is in the San Juan islands which are near the Canadian border. What part of the country do you live? Is my understanding correct that the Jubilee was made for one year only?

just for info, if yours works, it works.
I have 3 NAAs at the moment. They all have the OP gauge like TallT pictured.

When I went to see about buying it I took my stethoscope and listened to the engine. The sound from within the pan was like an industrial sewing machine. I could see that the head had been off cause it had no red paint on it. So I concluded that whoever had the head off did more than just valves because of the smooth crank sound and the high oil pressure. So I bit the bullet, while naively ignoring this other mysterious noise, which I now know is my old Vickers vane pump. :)

I'm wondering if you have a Jubilee guage and I have like a '54 NAA guage. (?) But it is probable that someone put the lower rated guage in your tractor.

"Our place is in the San Juan islands which are near the Canadian border. What part of the country do you live? Is my understanding correct that the Jubilee was made for one year only?"

I'm in the Canadian Gulf Islands group of islands just north of you.

I spent 5 days last July in Friday Harbor and it blew me away. I have never been to a more friendly, loving place in my life.
when I got back here and told friends about that they said, "Ya just like Salt Spring Island." I said, "No, waaaay more friendly." :)

The Jubilee is a 1953 only tractor indeed. But the body style and size remained for some time. In 1954, the Jubes were known as NAA's and where ours reads "Golden Jubilee Model" the '54 emblem has just a ring of stars. So our Jubilee's are actually NAA's but the '54 NAA is not a Jubilee. :)

Terry,
Good to hear from You. Our place is on Orcas island in the San Juan Islands. You are obviously familiar with the San Juan islands. We have traveled by boat in the Canadian Gulf islands years ago I always wondered what the difference was between Jubes ands NAA's. Now I know. I also ended up with the Farmall Super C and the TD 6 crawler which were on the farm next to our place. Both tractors were in terrible shape . Both rebuild and working now.

Soundguy,

I have an older oil pressure gauge which was used on a onan welder engine.I use this gauge as my test gauge for my ford jubilee. Yes, 1/8 inch pipe for oil pressure line. My test gauge goes to 50lbs. Same readings for oil pressure as the gauge which is in the dash of the Jubilee.
 
your probably right, I had a friend, now deceased, who grew up on a quarter section farm, they had a 8n and a farmall m, the 8n got ran so hard and long it needed sleeves and pistons every 2 years the m could go 4, but that was in west Texas around Amarillo, and he admitted maintenance was a seldom thing, maybe a grease job once in awhile and oil change twice a year , I use the jubilee almost daily, but I maintain it too, grease job before every brush hog job as most of mine are hard if not downright dangerous, I wouldn't let anybody but me do 2 of them, and oil changed 4 times a year , to date I have 1 oil seep on the rear main, but no oil burning , the brush hog u joints are the ones that came in it, even though ive had to weld angle iron skids to the bottom of the deck due to wear from use , I also grease the other implements before use each time, it pays to take care of equipment
 
Soundguy,

My apologies if you thought I was questioning anything you wrote in response to what I wrote.
Yourself and others on this forum have a lot more knowledge than me It seems I am continually asking for information. Maybe someday I will be able to provide info. I put a Paulson loader on my Jube. Keep the front tires at 30 lbs and front end greased. Works good and no signs of wear or breakage of front end parts. Would like to know if
other owners if jubilee tractors have loaders on their jubes
would like to see pictures
 
i have a ford 711 loader on my NAA

i had just put some auction tires and rims ( from a mf i think ) on her in this pic.

Soundguy,
Thank you for the picture of your jubilee and the ford 711 loader. Great picture, loader looks like a well built heavy built loader.
 
I would say that pressure is good you don't need much for a small engine and for as forgive engine like they are they will hold up to a lot, when watching a demo at the fairgrounds those engine get real hot and have probably no oil pressure and the engine will still fun after the show I would think 15 to 20 psi would be fine but you have a step up from that. you could also try thicker oil to help protect and fill the worn space of the bearings and such
 
Zman,

Good information. I would imagine if my Jubilee were run at PTO rated rpm pulling a disc or a plow for 8 hrs the oil pressure would be a lot less than I have now. I have a loader on my jubilee and use it only for moving things around our small piece of property and moving dirt once in a while.
 
Tall T,
I would like to know how his loader attaches to his tractor. The loader on mine attaches at the front under the engine There is a metal piece with two holes in it. Back of loader frame on mine attaches to the axles at back using the fender bolts.
Bracket on mine Looks like it came with the tractor.
My loader is a Paulson, front pump drive but mine does not have down pressure . Up for loader frame and up and down with hydraulics on the bucket. I think the 711 loader on Soundguys tractor is a nice looking addition to his tractor.
