Tractor Story

[BIGNASTY]

I have been keeping an eye on a tractor thats been parked in the bushes and now that winter has shown up the vegetation is dwindling it became more obvious what it was. Anyway I stopped to talk with the owner while he was attempting to dislodge it from the growth. Frustrated he said " YOU GET IT OUT OF HERE IT'S YOURS" 40 min later he singed over the ownership to me and I loaded it on the flatbed fired up the Dodge and I have a NEW WORK IN PROGRESS


Turned it over by hand and no uneasy sounds came from the motor, put in a charged battery and pulled the coil wire off and removed the plugs squirted oil in the holes gave it a spin sounded pretty decent. Ran a compression test 1st & last hole were 120lbs the center hole was 110lbs

Put everything back together drained & cleaned the fuel tank and fired it up & ran good but smelled like it was VERY RICH adjusting the Zenith carb made no difference. Pulled the air cleaner and it looked brand new Scratching my xxx I noticed that the air intake was almost melted closed, removed the plastic air intake RICH CONDITION SOLVED. Still didn't solve the compression difference so I figure it's a burnt valve or blown head gasket.

Upon more investigation the innards don't look bad and I can see that the hour gauge could be about right with the lack of sludge build up.

Whats your thinking???

How about a pic of the tractor?

10lbs difference in compression is negligible. Get it running and check again after a few hrs. They’ll all probably come up a little.

Agree 10lbs is nothing. If you want to knit pick a leakdown test will tell you a lot without tearing anything apart.

Jeez that looks like a Kubota but I see a carb too!

First pic shows a "Perkins" nameplate...

Yup. Saw that too, but I don’t think Perkins makes a baby like that.

That was my thought as I was reading post 1.

Massey Ferguson?

 

[BIGNASTY]

Yes its another MF 135 like my other one only a year difference. When I noticed it in the rough I was hoping its would be a AD152 motor instead of the AG152 (Gas vs Diesel) a family member seems to always be borrowing my tractor and forgetting it has a home and I have to retrieve it when I need it.

The Perkins is a staple in lots of tractors along with Continental 4 cyl. Never had a chance to get into a Continental so I don't know much about them. The Perkins is a work horse I fill the tank on my other tractor and run ALL DAY without refueling. Both have the 8 Spd foward & 2 Spd reverse trans with 2 position clutch.

When I started in the woods 35 years ago I bought a 1967 Massey Ferguson Treever. It had an AD 152 Perkins in it. Great motor. Sipped fuel. Hated to start below 20F. The slightest wif of starting fluid and the starter would lock. I had to use a propane torch to heat the intake.

Since I don't have a leak down tester I'm going to do it the old fashion way bring the suspect hole to TDC on the compression stroke and screw in my compression tester hose hook the air compressor to it and listen for air in crankcase, exhaust, radiator hoses.

Checking out the rebuild kit for the motor is only about 4 bills I might just as well do a rebuild and rest knowing that my Daughter isn't going to yelling Daddy-O my tractors out in the back forty and it won't run!!

10% difference between cylinders is what the industry says is expectable. You are just under. I'd run it some more maybe fog it a bit with some marvel and see if that helps free up the rings. as long as the valve are not adjusted too tight you shouldn't have a burnt valve, a rusty seat maybe burnt not so much...

Reminds of these ancient proverbs--------- "Mother may have and brother may have, but blessed is he that haveth of his own." "If you need to borrow something more than twice, you need to buy one."

I like this alot,

I have a sign in the top of my tool box that says

all these tools are at their home remember when you finish abusing them replace them from where they came from CLEAN!!!

 

[BIGNASTY]

As I said I put air pressure to each Cyl and found are escaping into the cooling system. Upon pulling the head (about a 1/2 hour you've got love the simplicity) these pictures are what I found

I rebuild Continental for my wife's Grandpa in his MF, they are decent but prone to cracking the block between cylinders and that is what happened to his that caused it to be left in the bushes for 15 years before I dragged it out. Had a very hard time finding a good block as most of them were cracked so that is a big issue if you ever look at getting one.

3/8 UNF 2" double threaded stud Something difficult to find? need one to replace one thats stripped on Exhaust manifold

Tractor parts dealer doesn't sell one for head to manifold.

Big hardware store will have them.

Thanks was at a parts house and they didn't have them and gave no reason, some of these folks aren't real forthcomming with info
