REAR TIRES

[Sjl]

My cub has 9.5x24 on the rear that are bad should I go back with the 8.3x24 or stick to the 9.5 tires on it

That's totally up to you. I personally like how 9.5X24 tires look, but to each their own.

Size of the tires can affect the ground speed slightly. I believe that I've seen some information that different size tires were optional on the tractor so you have some options and as stated it's up to you. Someone posted that later model FCubs were equipped with 9.5 tires from the factory.

Hi,
Welcome to the website.
You didn't say what year the Cub is.
Both sizes of tires you wrote are used on Cubs, maybe you knew already.

Ok thanks for your help. it is a 74 cub. I was just wondering I didn’t know if the previous owner just changed them to this size or what

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.
It shows how Cubs originally looked in it. The lube section begins on page 59.

There is tire size info and inflation pressures on pages 49, 50, and some tire info on page 74.

This manual shows the electrical system that a 1965 Cub originally has, which was about the same as a 1974 Cub has, except for the ignition switch.
Cubs made after mid 1964 originally had 12 volt, negative ground electrical systems.
The manual shows both 6 volt and 12 volt systems, disregard the 6 volt info.

The Case IH Hy-Tran fluid talked about in the manual is sold at Case IH dealers.

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.

There is a 1974 Cub operator's manual at the top of the page at Quick links, then click on PDF Manuals. I can't post it here.

Thank you so much for the information. I just mine last week trying to get everything working on it. Cranked it for the fist time today the clutch is stuck and not working and the rebuilt carb is leaking out weep hole so needs more work.

However I’m wanting to restore it and keep it going it has been a fun project so far.

Hi,
If the clutch disc is stuck to the flywheel, you might be able to free it by working up through the hand hole under the clutch.
Have someone sit in the seat and hold the clutch pedal down, and with a good light, use a large screwdriver or small pry bar, and gently try to free the disc from the flywheel, and from the pressure plate too, whichever it is stuck on.
There is a pic of the clutch on page 52 in the operator's manual above.

on a 74 the 9.5 works good,---on older ones I prefer the 8.3's. ----helps a tad on the hp and ground speed.
