Farmall Cub

Hi All,

I just picked up '66 IH Cub with a woods mower deck. I have some things to work out on it, between bogging on a incline, throttle not returning to idle, also a low (1000) rpm at full throttle, left brake pad not applying and just now the carb started leaking fuel when off. I am glad to see there are manuals here to go through. This is my first tractor and one of the deciding factors on it was how active of a community and following it has behind it. I also like how the design has stayed relatively the same for many years. Anyways nice to meet you all.

Welcome to the forum.

Welcome to the forum from a fellow Nutmegger.
Suggest you read this; What to do with a Cub you just brought home
After your 2nd post you can access the PDF Manuals in the Quick Links drop down menu at the top left.

Bogging down on an incline could be any number of things. Governor not responding, timing off, valves not fully opening & closing, dirty plugs, etc. Throttle not returning to idle and low RPM at full throttle could also be governor related. Leaking carb, most likely the float is stuck. There are some good posts on servicing the carburetor. Make sure you read them before taking the carb apart. Usually a good cleaning is all that's needed.

Hi,
The Cub operator's manual can help you learn about maintenance that the Cub needs.

Below is the 1965 Cub and LoBoy operator'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, and the index begins on page 75.
It shows how Cubs originally looked in it. The lube section begins on page 59.
Changing the trans, final drive, and steering gear oils are on page 70.

http://farmallcub.com/rudi_cub/www.clea ... index.html

It shows the electrical system that a 1965, and 1966 Cub originally had.
Cubs made after mid 1964 originally have 12 volt, negative ground electrical systems.

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 manual tells how to check and change the Touch Control fluid, and remove the air from the system.
Be sure to check the fluid with the arms in the rear, or down position, the manual says to also.

I would check or change all the oils before using the Cub. Using a Cub with low oil in a gear housing can damage the parts in it.
There are 3 separate gear housings at the rear area of a Cub, with 3 separate oil levels to check, the transmission, and 2 final drives.

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 owner's manual tell how to change the oils, and what oils to use.

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.

Welcome to the Forum! Take some time and read through a few threads to acquaint yourself with the Forum:

Don't know if you have any of the manuals to your tractor, but once you’ve logged your 2nd post, you'll have access to the all the PDF Manuals on this site. There’s a few ways to do that:

• From a desktop or laptop, go to "Quick Links" in the upper left corner of your screen. Hit that and a pull-down appears where you'll find "PDF Manuals".
• You can also go to “Cub Info” in the upper toolbar, then hit “Rudi’s Manuals”. From there, you can access a variety of information.
• If you're using a phone, go to the "Links Directory" (second category down the main page). Once in "Links Directory" , scroll down to the second section "Tractor Parts & Manuals" and you'll find them there.

There are a lot of good threads dealing with Cub repair and maintenance in the How To Forum, located here: http://farmallcub.com/phpBB2/viewforum.php?f=11

We’d encourage you to take the Safety Test located in the Safety Forum: http://farmallcub.com/phpBB2/viewtopic.php?f=33&t=68084

Take some pictures of your tractor and post them, we’d like to see it.
