How to tell 6V from 12V system

[Eugene]

One problem is that (In true Paw Paw fashion) the hand crank is missing, so attempting to free the motor that way isn’t an option. I may have to take the head off and tap the pistons.

Remove spark plugs. Soak piston heads with solvent. Tractor in 3rd gear. Rock the tractor using a rear tire.

Shane N, is there a mounting bracket that fits with that alternator you’d recommend?

Grandpa probably used a Delco 10SI alternator.

Not sure if he still is making them, but Bill (aka Barnyard) had some nice handcranks for sale. You might send him a PM, if you want to make things easier on yourself.

Also, if you do a search, you will find postings with several different ways to use your existing bracket for an alternator. Or you can post on the VINE a request for one...there are forum members who make brackets for alternators.

I'd encourage you to fully utilize the Search box in the upper right of each screen. By typing in a word or phase, you can get quite a listing. But each set of returned results has its own Search box above it on the left side, where you can search that listing for more specific terms.

For example, I typed in "hand crank" in the Search box (upper right corner of screen). That resulted in 2153 matches on the forum. By the way, if you use quotations marks, it will hit all the posts that have the two words "hand" and "crank" together, as well as individually. If you leave out the quotation marks, then it will only return those two words wherever they alone show up. In this case, hand crank returned a list of 2758 matches. Moving on from there, once you have the first batch of matches to the phrase "hand crank", then go over to the left side of the screen above the listing and you will see another Search box. In that I typed "dimensions" (I didn't use quotes in that box since it was only one word). That search returned 34 matches containing the words dimensions, hand, crank. I went to the 2nd posting by Don McCombs and there was a PDF dimensioned drawing of a Cub hand crank. Here it is:

Here's a thread in the How To Forum on properly hand cranking a Cub: http://farmallcub.com/phpBB2/viewtopic.php?f=145&t=46811&p=386701&hilit=hand+crank#p386701

Earlier, I also gave you a link to a posting back in your first thread "Confusion about year of my cub" on What to do with a Cub you just brought home. In it are many, many good tips on what to do in your situation.

You mentioned that this Cub was inherited. I would also suggest that you go back to wherever this Cub originally rested and ask or search for the hand crank and any other Cub-related items. Unless the property was sold, you should have family access and rights to look around for it. Now that you can have a dimensioned drawing, you'll know what to look for.

You're doing good by asking questions. Members here are anxious to help.

I know it would be a 5 hour drive from the beautiful hills of Blue Ridge, Georgia, but if you could make the time to travel to Sneads, FL on Feb 14th and 15th, you'd have such a great time and learn so much from fellow Forum members. They'd welcome you greatly! Here's the links to the CubFest calendar and Deep South CubFest.

Without going back and reading all the posts has anyone thought that this is a 6v tractor that used a 12v coil with a resistor because a 6v coil was not available?

The ballast resistor is used to drop the voltage through the coil and to the points by about 50%. Using the resistor on a tractor with a 6 volt electrical system would drop the voltage to somewhere around 3 volts.

The points need to operate in the 4.5 to 9 volt range.

A 12 volt coil will work ok on a 6 volt electrical system.

Agree with Eugene, remove the plugs and soak the cylinders with your favorite penetrating oil/witches brew. You can't do any harm and it will lubricate the cylinders, maybe free the rings. I would not remove the head unless there is no other choice. The head bolts are notorious for breaking if not been removed in a long time. They penetrate into the water jacket and the threads are usually rusted making them difficult to remove. If you remove the starter you can try moving the crank with a pry motion on the teeth of the ring gear. Try to move it in both directions. While the starter is off you can test it for operation by connecting it to a battery with jumper cables. 12v won't damage the starter as long as you run it briefly. A family tractor is worth a lot of effort to save it, IMHO. Don't give up and Good luck, wish I were closer to your location.
