1940 9N needs to go back to work.

Client wants to get an old 9N running and working on the farm... always helps to have another working tractor. It came with the property, hasn't run for 15 years. I did some preliminary work on it in 2017, new coil, fixed a radiator leak, cleaned out the carburetor bowl, but never had the time to officially try to get it running. I have it in my shop now, so on with the job.

I know the former owner who last ran it, said it was a good tractor, useful for hauling hay and other work.

Seems to be in recoverable condition:
1. The left brake is very weak, leaking goo out the drum.
2. The electrical system bad. Wires, switches all crummy.
3. Who knows what will show up when I formally get into it?

So, any basic references or guides in going over the ELECTRICAL system? I'll test the 6V generator, and if ok, I may keep the 6V system. Otherwise might go for the YT conversion for $105.

How much of a job is it to pull the left BRAKES and replace seal, clean or replace lining?

What else in general do y'all recommend when putting an oldie back to work?

I started my first 8N project this fall. I had the same break problem. I read as much as I could but I still found it helpful to take many pictures. I took a picture after each part of as removed. I also had room to layout each part as I disassembled the rear end. With advice from this site and my pictures the reassembly was a snap. Great confidence builder. I ended up replacing breaks seals and bearings and loose lower 3PT pins.. Finished rear end below.

Put out the $$ for at least an fo4 manual. Not a hard job, just time consuming. 8n and 9n brakes are 2 different animals.
Looks like your lower 3 point lift arms are leaking also. That requires removing the left trumpet as the nuts are on the
inside. 150 ft lbs torque. Right side can be reached from left side.
Install sure seals on axle. Clean wheel bearings as good as possible then fill them up with wheel bearing grease. I have a
sure seal with a grease zerk in it for filling the bearings..
Keep in mind 9/2N brakes are NOT a strong point on these tractors.
 
Looks like the right rear seal is also leaking. Don't even try to clean the brake shoes, once they are oil soaked you can't get it out. Looks like the left pitman arm seal has been leaking or the transmission top cover. Have fun.
 
I'm a Ford "N" owner with only one year owner ship.....

I purchased a 2-N that had not ran for more than 30 + years from the original family....

I was assured the hydraulic lift cover had never been removed.....

Good thing I listened and removed cover.......

It's your $$$$'s....

I replaced every electrical wire I could see / find...

Cleaned all electrical connections.....

Tractor starts and runs perfect on the 6 Volt system.....

As long as the owner maintains the 6 Volt system......I see and know of no problem with the 6 Volt system..

If and when your Tractor is placed into service, and if the OIL / Hydraulic system is contaminated ....you shall be spending $$$$ on the hydraulic system...

Inspection and cleaning is a small amount of $$$$$ compared to replacing parts...
