Lower Holes on Bellhousing?

Postby Nautiluscont » Thu Nov 19, 2020 6:28 pm

New to the forum and new to owning a 48 Cub.... I would imagine this has been covered here before but a simple search didn't bring anything up. Can anyone explain what the lower hole shown here is for? It is a thru hole but their appears to be a shaft in the center (drift shaft or cutch lever?) in the way. Is it simple another attachment point?

Thanks

Attachment. It should be threaded for a bolt

Hi,
The holes are for attaching Cub implements to, and originally had 5/8" coarse threads in them.
All the holes in the 4 pads on the clutch housing originally had threaded holes for bolts.

If the 2 holes have no threads, someone probably wore them out somehow.
The Cub 22 mower fastens on using those 2 lower holes, on the left and right sides of the Cub.
I saw one in the past that the holes were wornout, probably from using the mower with the bolts loose.
The Cub 22 mower vibrates lots, and moves around on the bolts.
The bolts have to be kept tight.
People on here drill the holes out, and put in inserts, so it will use 5/8" bolts again, if the threads are stripped.

The shaft inside the clutch housing goes from the clutch to the transmission, and makes the tractor move.

If some of the holes there, or in the final drives, have holes that are not open, they might still have the original cork plugs that IH put in the holes to keep dirt out.
They screw out of the holes usually.
The final drives have 5/8" implement attaching holes too, 6 holes on each final drive. :)

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

Below is the 1949 Cub 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.
It shows how Cubs originally looked in it. The lube section begins on page 14.

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

It shows the electrical system that a 1948 Cub originally had.
Cubs made before mid 1964 originally had 6 volt, positive ground electrical systems.

The 10W oil mentioned in the manual for the Touch Control, was changed later to use 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.
I guess you have no Touch Control, there is none in your pic.

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 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.

There is a search box at the top of the page, to the right of the Farmall Cub, you can search for info on the website that people have posted.

Cubs originally came with a different style seat than the one in your other pic, they have seats with a cushion also.
Below is a listing at TM Tractor for a new seat, you can look at the pics.

http://www.tmtractor.com/new/se/356fp.htm

TM Tractor is at the bottom of the page.

There is also a smaller rod inside the clutch housing, from the clutch pedal to the throwout bearing.
Page 40 in the manual has a pic of the clutch, and what is inside the clutch housing.
Good luck with the Cub. :)
