Hi,
The Cub owner's manual can help you learn about maintenance that the Cub needs.
Below is the 1947 Cub owner's manual. The experts on here recommend people read it. It has lots of info about operation, maintenance, and lubrication. There is a table of contents on page 1.
It shows how Cubs originally looked in it. The lube section begins on page 14.
http://farmallcub.com/rudi_cub/www.clea ... index.htmlIt shows the electrical system that a 1947 Cub originally had.
Cubs made before mid 1964 originally had 6 volt, positive ground electrical systems.
The charging system originally has a cutout, or Relay, IH called it on top of the generator, there is a pic on page 33 of the manual with the hood off, showing the electrical system.
It has a 4 position charge and light switch on the dash, to control the gen output.
It was before Cubs had voltage regulators, you had to choose the charge rate yourself.
The switch has 4 positions, L, low charge, H, high charge, D, dim front lights, and B, bright lights.
The electrical system info begins on page 32 of the manual, and using the switch is explained on page 34.
You should be able to see what it is charging on the ammeter, when the engine is running.
The engine has to be above idle speed for the gen to charge.
There is no Touch Control info in the 1947 owner's manual. It is in later owner's manuals.
The Touch Control uses Case IH Hy-Tran fluid. It is sold at Case IH dealers.
There are other brands, be sure it works with IH hydraulic systems before buying one.
The newer manuals tell how to check or change the Touch Control fluid, and remove the air from the system.
Be sure to check the fluid level with the arms in the rear, or down position. The manual says.
I would check or change all the oils before using the Cub. Using it with low oil in a gear housing can damage the parts in the housing.
There are 3 separate gear housings, with 3 separate oil levels to check, in the rear area of a Cub, the transmission, and 2 final drives.
The manual tells how to check and change the oils.
The transmissions in Cubs commonly get water in them, from rain, or condensation inside the housing over time.
The air cleaner is an oil bath air cleaner. Dirt that is sucked in settles to the bottom of the oil cup. It should have clean, light motor oil in the oil cup to work right.
The fan hub needs oil in it to lube it.
Putting oil in the fan hub is shown on page 28 of the manual.
I use a clean pump oil can to pump oil into the hub.
The hub uses motor oil.
Something sometimes not greased as often as it should be is the clutch throwout bearing, people on here have said.
It tells how on page 21, at number 28 on the page.
You have to remove the hand hole cover under the clutch area, and the grease fitting is inside the housing.
You probably need a light to see it, and have the Cub in a building, so you aren't looking up at the bright sky.
The original style throwout bearing has graphite material. They have said on here to use cheap grease, so the oil in the grease absorbs into the graphite material.
Other manuals can be found at the top of the page at Quick links, then go to PDF Manuals,
or at Cub Info, then go to Rudi's Manuals.
There is a search box at the top of the page, to the right of the Farmall Cub, you can find info in posts that have been made.
