Student Farmall H project

djsinseia · Feb 2, 2010

I have a student who just brought in a Farmall H for a restoration project and have some basic quesitons.

Serial number is 238651. Can anyone tell us anything about this tractor? Year of mfg.?

The tractor has a belt pulley and no fenders. I'm assuming there were originally fenders for it even though his dad says he doesn't every remember them. Maybe they were removed be someone? maybe to mount a picker?

Tractor has been sitting inside for at least 10 years. His dad thought the engine would turn. Well it won't budge when we put the tractor in gear and try to rock the wheels.

Where do we begin? Maybe dump some diesel fuel in the spark plug holes and let it sit for a day or two?

Tractor has a generator.....am assuming it takes a 6 volt battery....but are these tractor positive or negative ground/

Thanks in advance!!!!

the h is a 1946. it probably did not come from the factory with fenders, they were an option. the tractor was originally 6v positive ground. regarding the stuck motor, there are quite a few different ways to unstick em. personally, i would first drain the engine oil and look for water or antifreeze. pull the spark plugs and peek in to see what the cylinders look like. if you can borrow a bore scope, that would be great. next, pick up a spray can of pb blaster penetrating oil. pull the valve cover, spray up the rocker shaft , and valves, spray the rest in each spark plug hole, put a fresh drain pan under the tractor and let it set over nite. look for penetrating oil the next day in the pan. at this point, fill the cylinders with automatic trans fluid and let the tractor set. check the tractor every day and look for atf leaking out of the drain hole. try rocking the tractor in 4 th gear every day to see if it breaks loose. also see if the valves are loose, and lube the whole works up with trans fluid. he may be lucky and the motor will free up.

you say its there for a restoration project, so i would think that means a complete tear down of everything. that is the way the students will learn how to use specialty tools like cyl. hone , torque wrench, ring groove cleaner, ring compressor, slide hammer and bushing installer and micrometers.and learn what specs are for. dont see any sense in wasting time soaking pistons when you can just start the disassemly process. in the end you have a good as new tractor. maybe this is too much as you didnt mention type of class, or who is responsible for parts and final bill.

There is just too great a chance of doing serious damage by not tearing the engine completely apart after standing that long. Good learning experience. That goes for the power train also. One rusted stuck ball bearing can do a lot of damage to housings and gears very quickly.

First thing I would do is go and get an Operators Manual and a Parts Manual. Can use the Case/IH site for the parts manual but I like the book in hand.

You need to get those manuals that was suggested. I would fill the cylinders with ATF and let it soak. You probably need to split the tractor and tear that engine down completely.
You need to a lot of pictures even some video and take a lot of notes and makes sketches. Keep all the parts from engine separated and marked as to where they were removed. Cardboard
boxes are fine and can be marked. This will save a lot of time when you get in the rebuild.

Need to have head reworked, block cooked, new cam bearings installd, crankshaft cleaned and measured for wear. Your local auto machine shop can get new bearings. Hal

I forgot the manual. Hal

I use heavy duty zip lock frezer bags and 3x5" note cards. I also use a digital camera and print pictures the same day and make notes.

Give us some more details. What part of the country are you in? What type of class? High school shop-FFA? I know I will and I'll bet this community would donate some extra parts.

It's a great project for high schoolers or FFA, Here is mine that I did for my high school senior project in 2008. PB blaster or Kroil penetrating oil and ATF are all good if it is not too stuck but it would be worth tearing it down completely if you want to do a top qaulity job.

You said he is going to restore the tractor then remove the head and go from there. I see lots of tractors that have been "restored" by school groups and they are not very nice new paint and tires is not a restoration . Get all the manuals and look at an H that is correct before getting into a project thats going to be too expensive. You can have 1000 real easy and thats not tires so maybe you better take another look at the job as you as an advisor need to know what he is trying to do. As a starter sleeves and pistons arearound 400 then remove the engine to get the crank ground and new bearings seals gaskets and there is the head it just goes on and on.

This is another example. Doesent sound like the instructor knows is familiar with the project of what it takes to redo a tractor as this subject comes up quite often on this site just because we are in a class doesent mean the instructor knows how to lead. It mean sound mean but i have seen too many tractors out of a class that realy were a mess when they call them restored.
