Hi,
Reading a Cub owner's or operator's manual can help you learn what Cubs originally look like, and about the maintenance they need.
Here are some things to look at before buying a Cub.
Check the castings for cracks, or broken places on them.
There is a place on earlier Cubs where the engine block can crack. It is at the right front area of the block, where the front end bolts to the engine. Look closely for a crack there, it can be covered by dirt or grease.
Below is a picture of the area, the crack happens in the corner. 1 bolt holding the front end onto the engine is gone in the picture.
There are 5/8" threaded implement mounting bolt holes in places on Cubs.
You could check the threads in the implement mounting holes.
Sometimes the threads are worn, sometimes the threads are worn out and gone. Sometimes the holes are broken.
There are 2 pads on each side of the front area of the clutch housing. Each pad has 2 bolt holes.
There are 6 implement mounting bolt holes on each final drive. 2 on each final drive hold the drawbar on, it's important those holes are good to use a drawbar.
There are 2 implement mounting bolt holes at the bottom rear side of the large square hole under the steering gear. The square hole is for mounting some implements.
Cubs originally came with a cork in most of the implement mounting hole. Some might still be in the Cub you look at. They might be painted over. They can look like a broken off bolt, but are not.
The corks are to keep out dirt.
All the 5/8" implement mounting holes originally have threads. You can screw a good bolt in the holes that have been used, if the bolt is loose and moves sideways, wiggling it, the threads are worn.
If you aren't going to use the Cub with implements, it might not be important to you if all the threads in the holes are good.
Sometimes the left final drive bolts that hold it onto the transmission housing work loose, and people keep using the Cub, I guess, and the bolt holes and threads wear. Then the threads need repair.
People on here have needed to put in repair coils for the threads.
The final drive is held on with 6 bolts in a circle. 2 bolts are under the bottom of the final drive, they come loose also.
They need checking and tightening once in a while.
It's probably not impossible for the right side to have this problem, but I haven't seen it.
You could check the right side bolts too.
I sent you a message, you get to it at the upper right of the page.
