New guy with 1967 Cub and Questions

[Joe in Grassy Creek]

I bought a 1967 International Farmall Cub about three weeks ago. It’s serial # 230506 J. It seems to be in pretty good shape.
It smoked pretty much (blue smoke) when the PO started it for me, but after it ran for a while, it stopped. I let it sit for a week while we were out of town, and it blew a little blue smoke when started it, but stopped after running for a while. I figure the valve seats and guides are a bit worn, but will last plenty long before I have to tackle that job. It’s got a few drips around the PTO, the steering box and the rear of the engine. Nothing too bad, but probably a winter job to replace the rear main seal and other seals. The transmission is a bit noisey in 1st and reverse, and I've already located a used one--another winter job!
I got the original Operator’s Manual with it, a Preventative Maintenance Manual for Cubs, Lo-Boys and the 140 through 340 series tractors, a Woods Rotary Mower manual and a Cub and Lo-Boy Service Manual. So I’m in good shape manual wise.
I’ve poked around the tractor and read enough of the manuals to come up with a few questions.
1. How do you tell the difference between a Cub and a Lo-Boy?
2. How do you tell if the tractor is a battery ignition or a magneto ignition?
3. The Owner’s Manual shows 3 ½ pints for the transmission, 1 ¾ pints for the rear axle housing, 1/3 pint for the belt pulley housing. Can I drain and replace the transmission fluid without draining the differential and rear axle housing?
4. What is a good substitute for the IH Hy-Tran fluid called for in the Owner’s Manual? I use a good quality synthetic 85 w 140 in my Moto Guzzi transmission and rear end---would that work?

I’ve been reading this forum for a few weeks. This looks like a great resource, and fine community of folks. Can’t wait to see photos from the Cub Fest.

Hi Joe welcome to the forum and yes you was right this is a nice bunch
of guys.A lot of the guys are busy this weekend with cubfest. I wished
I was there but too far for me.

Joe a magneto looks like this with a plastic box on top. The coil for a magnito is under the box. Many times because of cost or availability when a mag coil went bad farmers woul substitute an external coil in place of the defective one.

This is a dist.

A low boy is closer to the ground than a standard cub.
Take alook around the home page and the links it leads you to and the first couple of postings in this forum and you will glean a wealth of info.

All right, question # 2 answered. Mine is a distributor with an external coil and voltage regulator.

I've noticed that many of the Lo-Boys say "Lo-Boy" on the original decals. Mine has the original decals, and they just say "Cub".

I thought seriously about heading up to Ohio for the Cubfest. Just couldn't work it in to the schedule. I'll definitely make the next one. I need to pick a few implements---and learn how to hook them up!

You have found a spot with a lot of teriffic people. Just remember, ask any questions.

Joe:

Welcome to the forum. Will give ya the spiel in a minute.

Ifn your decals say Cub and not Lo-Boy, you got a Cub. It is about 8 inches taller than a lo-boy. A lo-boy is meant more for cutting grass as it is kind of low for row-crop gardening.

3. The Owner’s Manual shows 3 ½ pints for the transmission, 1 ¾ pints for the rear axle housing, 1/3 pint for the belt pulley housing. Can I drain and replace the transmission fluid without draining the differential and rear axle housing?
4. What is a good substitute for the IH Hy-Tran fluid called for in the Owner’s Manual?

K, the easy answer is yes. They are separate entities. Check the GSS-1411 Service Manual, which is your Lo-boy Service Manual. The directions for performing these tasks are there as well as visual indicators (pics) on where to find the correct drain plugs.

As for the Hy-Tran. If you do not have a CaseIH Dealer near you, or a I gotta bite my lip here - John Deere Dealer nearby, I think MSO1285 or equivalent is what is asked for.

a Woods Rotary Mower manual

Which Woods Mower Manual is it?

I use a good quality synthetic 85 w 140 in my Moto Guzzi transmission and rear end---would that work?

There can be a lot of debate on what oil to use. The Owner's Manual says 90Wt gear oil, and that is what I use - right from the CaseIH dealer.

I guess you will have to think on that one. I don't think the synthetic will do much harm.... but I do not use synthetic oils in any of my engines. Ithink my mini-van uses it, but I am not sure as I have not done an oil change or added oil to my van in 3 years. The dealer does it. For $24.00, I let him get greasy..

I need to pick a few implements---and learn how to hook them up!

Well, I guess it is time for the spiel. For you implements look on the Manual Server under Cub Implement Manuals -- see in the welcome text that follows. Also, once you have perused those, visit [url=http://www.tmtractor.com]TM Tractor Parts{/url] and their Implement Gallery to see how things go together..

irst, welcome to the greatest forum on the internet, and to the Cub Family. You will find that all the folks on this forum are kind, helpful and just full of Cub info and knowledge. They also happen to be the finest folks I have ever met

Ok, so here is the spiel.

I would suggest that you read this thread: New Members and Visitors, Please READ. There are many great links to informative pages such as the ATIS FAQ's (both 1 and 2), The Best of H.L. Chauvin who has written very interesting articles on troubleshooting common problems with your Cub.


Also, you might want to visit the Cub Manual Server as there is tons of info on servicing, maintaining and re-building your Cub.

I would also recommend that you visit Binder Books and purchase the Owner's Manual, the GSS-1411 Service Manual and the TC-37F Parts Manual. Although they are available on the server, it is better is you also have your own paper copy. Binder Books is the only licensed IH publication reprint shop and they have the best quality.

I truly hope that you enjoy your Cub and that you will be a frequent contributor to the forum. Again, welcome to the Cub Family

BTW, a LoBoy is EASY to differentiate from a regular Cub. It's "lo(w)" to the ground, hence the name "LoBoy." Classic Cubs look like little tractors, and classic LoBoys look like big go-carts with tractor tires on them.

There are also three other "Cub LoBoy" models, the so-called "numbered Cubs," which look like giant lawn tractors. They're easy to spot too.

[ScottyG]

Funny.

[Buzzard Wing]

I used 80-90 (gear lube) in the steering gear, Hy-Tran in the transmission and the final drives. BUT most folks use gear oil in all 3. Book says it is ok to use in trans and final drives..

Try a search, as there was a very good thread regarding the composition of HY-Tran that convinced me to use it in the final drives and transmission (everyone says it is 'louder' with Hy-Tran)

Easiest way to tell a lo-boy is that the steering arms (whatever they are called) is on on the top and one on the bottom. Cubs are both on top.

[beaconlight]

Buzzard Wing As with everything else in life, what you say is generally true about the steering links. The first lowboys had both on top. Tom at TM explained it to me once but suffering from CRS I am luckey to remember as much as I do. I am sure one of our experts can explain it.

The early ones had tie rods like the standard cub but the Ackerman steering geometry was wrong for the shorter wheelbase. That was corrected with the over / under configuration.

[Joe in Grassy Creek]

Rudi, the Woods manual is for a Model No. 42C-4. It's titlted "Owners Manual and Parts List with Assembly Instructions" form F-4136 (Rev. 3-74) on the cover. Most of the other pages were revised in 1968 and 69. If any one needs a copy of it, I can scan it and email.

[Rudi]

Joe:

Seems I have that manual already. Many thanks though. Do me a favour though would you. Could you check out the Woods Manuasl under OEM Implement and Attachment Manuals on the server. If you have a better copy, I sure would appreciate a good scan. Many thanks.

Hey Joe,

Welcome to the board and the Cub community. Like you, I wish I could have gone to the CubFest, but couldn't do it. Where are you located in Baton Rouge? I work for the LSU AgCenter and go to BR often. We should get together sometime and swap names .

['Country' Elliott]

Hey Joe...WELCOME!!! We'll be happy to swap y'all information for some a those GREAT hot seasoned Louisiana "Mud Bugs". .. a pot a Gumbo. ..AND, a good-sized bucket a Prawns!
