I just purchased an International Cub Lo-Boy and I need to find out the year, model and to know if the engine block is correct.
my Serial Number is 2159 with a J behind it. the lock shows 351686-R2 with a L2X below. I was given a single plow, disk, scraper box & Rake. it also has a Woods aftermarket belly mower. any help would be great as I would love to keep it running as long as possible and possibly recondition it.

Your Cub is a 1955 Loboy. The block number you gave is the part number. The serial number is needed to determine if it might be original. That number can be found above the oil cap.

Or a cast code can tell also.

Welcome to the forum. Click on the Cub Info tab at the top of this page. There's also a lot of information on forum sponsor TM Tractor's website. Click on the link at the bottom of this page. BTW the first year of mfg for the offset Cub LoBoy was 1955, beginning SN was 501. Stan

By 1955 when Lo-Boy 2159 was built, the engine block part number was 251341R7. The number quoted above, 351686R2 is the part number of the bell housing. Information on the engine can be found as Barnyard posted.

Thank you all. I will be next to it in January where I can see the tractor. I'm currently 5 hours away. I know it's a 6 volt but having trouble starting without a jump even with a new battery so I have ordered a rebuilt starter to install. hope that fixes the it.

It may not be the starter. Make sure all electrical connections are clean. A little bit of rust can give you a no start condition.

Or corrosion on the wiring, and/or paint that's keeping the system from grounding. The electrical system including the starter must have a clean ground path through the frame to the battery since this is the grounding path. JMHO Stan

Also, a 6 volt system requires excellent cables. If the cables are in poor condition or have been replaced with smaller 12v cables you’ll have the same problem.

I agree with Stan and Gary. Corroded or too small of battery cable could very well be the issue. I recommend using #2 gauge welding cable as a replacement for the lead from the battery to the starter. Make sure the ground cable and connections are good too.

I ordered a rebuilt starter and it worked. I will have the Delco rebuilt so I can reinstall it to keep it all original. it has 12 volt cables so I will have to order larger cables.

Hi,
Below is a listing from TM Tractor Parts, at the bottom of the page, for the battery to starter cable for 6 volt Cubs and LoBoys. You can look at the pictures. It says it is number 2 cable.
That is the size of one that I bought at Case IH in the past, for a 6 volt Cub.

The LoBoy operator's manual can help you learn about maintenance that the LoBoy needs.
Below is the 1957 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 80.
It shows how LoBoys originally looked in it. The lube section begins on page 21.

It shows the electrical system that a 1957 LoBoy originally had.
Cubs made before mid 1964 originally had 6 volt, positive ground electrical systems.
They have said on here that IH didn't make a new manual every year.
I sent you a PM, you get to it at the top of the page.
