removing rear tire(s)

hello:
I'm new here and own a 54 cub with touch control and i have a few questions about removing the rear wheels. First..what size socket/ wrench do i need to remove the rear wheel from the axle?.. My cub is at our camp and i have to take up tools to work on it.
Second question what size wrench do i need to remove the wheel weights on the rear tires.. and lastly..I'm putting new rims on the back..liquid came out of one of the valve stems and rotted out the rim around the valve stem. I have read that the origional nuts holding the wheel dish to the rim will not fit on the aftermarket rims i just bought and i was told to use grade 8 carriage bolts instead.. what is a grade 8 carriage bolt?.. will it be the right length or do i need to i need to find ones the right length ( 2.. 3 or maybe 4 inch ??).and will i need washers?.. should these bolts and washers be galvanized??
lastly.. i'm sure i read somewhere that lime is added to the calcium liquid in the wheels, to prevent it from being corrosive.. is this true??
thanks in advance for any help you may offer

Off hand I cannot remember the bolt size.. but suffice to say.. one of your wrenches/sockets will fit. Bring ALL of your tools , because for sure.. you will forget the one you do need.

Now, there is a post I just read.. will go and have a look at it again in a minute and add it here, that George Willer responded to.. and he describes this fix well. The carriage bolts will not sit in the repro rims properly, hence the fix is a larger washer used in conjunction with the carriage bolt.

Ok, so I have another question. I just bought a used center hub for one of my rear wheels. The hub is held on by four square head bolts to keep them from turning in the channel they slide into. They were extremely rusted so I went looking for replacements at the local hardware stores with no luck. What are some possible solutions to this problem since I can't seem to find square headed bolts? I tried a standard Hex head bolt which just turns on the channel.


You could use longer hex head bolts with heavy washers under the heads so they don't go inside the "channel". If I remember right it's necessary to do this with some reproduction rims. One of my Cubs is fitted this way.

Now for a neat chart on Bolt Grading.. look here at ASTM & SAE Grade Markings for Steel Bolts and Screws for info on the difference in Bolt Grades. Grade 5 will break under load and are somewhat useful when shearing is desireable prior to attaining shatter points.. but Grade 8 is better when shearing is NOT desireable such as in Tire Applications. Bolts and washers do not need to be galvanized, and in fact if you wish to paint em.. you don't want them galvanized... unless of course you are going to re-galvanize your rims.

As for adding lime to Calcium Chloride.. nope know nudding about that.. but I do know this, I won't load my tires.. on a Cub, rear wheel weights should be sufficient and if not, then double the weights.. forget the CaCl.. in my opinion.

Do get the manuals.. they are a basic requirement.. Glad to see you here.. there are a few in your area that are quite knowledgeable about Cubs and will pop up shortly. Looks like a need for another mini-fest.. Timmy's, and Cubs.. and Cub-a-holics -- a perfect match :!: :wink: :D :D

Ok, so here is the spiel

I would suggest that you read this thread: New Members and Visitors, Please READ Prior to Posting. There are many great links to informative pages such as the ATIS FAQ's 1 and ATIS FAQ's 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. In addition to this basic information, there are also a number of other useful tools available on the server. There is the Specialty Services page which has contact info for neat stuff like getting your seats recovered, buying quality Decals, Serial Number tags and a host of other neat items. Also there are the Parts Pages - both Used Parts Suppliers and New Parts Suppliers pages with links to quality dealers. I am always looking for YOUR favourite dealers for New and Used Parts to include here. These pages are intended to complement our Official FarmallCub.com Website Sponsors:
I would also recommend that you visit Binder Books and purchase the three most important manuals you can own for Maintenance, Repair and Rebuilding your Cub. These are the Owner's Manual, the GSS-1411 Service Manual and the TC-37F Parts Manual. Although they are available on the Cub Manual Server, it is better is you also have your own paper copy. Binder Books is the only Authorized IH Publication Reprint House and they have the best quality manuals available. Most other's are not of the same quality. Just a personal thought here, the I&T Shop Manuals, although helpful in some areas, really are not sufficient for the job. If you wish though, they are good additional reference works.

IF you really want to get the skinny on all things Cub, might I suggest you get a copy of Ken Updike's Farmall Cub and Cub Cadet's :?: . While you are at it Original Farmall Cub and Cub Cadet is Ken's latest addition to the series. Along with Guy Fay's Letter Series Originality Guide, these are three must have's in anyone's collection.

In addition to the above information, don't forget to check out the various articles that are available to help with your Repair, Restore, Rebuild or just your Maintenance Projects. There are a number of sub pages such as Electrolysis or Rust Zapper's, Maintenance Tips, Jigs and Techniques, Implement and Part Sketches and of course the Paint, Decals & Other Finish Questions which has the Paint Chart and the Paint Committee Decisions links.

Oh, and while the program still lasts.. you might want to check the Announcement: Navistar Free Gas Cap Offer - On-Line Form thread at the top of the Cub Forum and send away for the new style safety cap before that program runs out as well.

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

Jamie - grade 8 carriage bolts are bolts with a round head that has a square shoulder underneath. The bolts that hold the rim to the wheel center are 1/2 - 20 and the length will be determined by the length of the mounting loops on your new rims. The 1/2 - 20 means that the diameter of the bolts is 1/2" with 20 threads per inch in the threaded area. Grade 8 refers to the hardness of the bolt. Typical general hardware bolts are grade 2, Grade 5 is a little harder and grade 8 is a very strong sturdy bolt. You can measure the length of the loops on your rims and add about 1" to 1 1/2" to determine the length of bolt you will need. Then go to a good hardware or agricultural supply store and tell them you need grade 8 carriage bolts of that length with nuts and lock washers. The same size bolts are used to hold the wheel weights to the center of the wheel.
If you are replacing just the rims, you will not need to mess with the wheel weights.

What for? When jacking up one rear wheel, wedging the front end only makes it harder to jack up that corner, and if you've got it effectively wedged, you end up jacking up the whole side of the tractor!

Exactly! And the whole tractor is MUCH more stable. Around my shop safety is more important than jacking effort. When I put a jack anywhere the wedges go in the front axle. Sometimes the wedges even make the job easier, such as today when I changed a couple pair of front wheels. My "farmer" type jack only had to lift the right sides.


Consider this: When the rear end is lifted from both jacking points and both rear wheels removed, a five year old could shove it over to the left unless the front axle is wedged.

Keep your wedges where you can find them easily and use them EVERY time.
 
Sorry I don't have the answer off the top of my head.... but 7/8" comes to mind and possibly 3/4"

This may help:

Also, the new rims from TM come with the carriage bolts too, but no idea the size

And as always, thanks for the sage advise GW! Some things you learn the hard way.... Like even when you finally know enough to wedge the front axle, that white cedar is not the ideal (or even good) for those wedges...
 
As George said If you jack up a cub always wedge the front axle as a precaution it ain't good to have one laying on it's side.

Just as a precaution
:wink:

George, do you use wooden wedges? If so, is soft pine or spruce wood an acceptable material?

Do you put them in from the sides (right angle to tractor centerline)? Or from the front/rear?

Thanks,
bald

Yes, wooden. I wouldn't use softwood. Mine are oak and well worn. :shock: Time to make more!

They sit on top of the axle tube and are shoved tightly under the limit stops, (right angle to tractor centerline). Sometimes it's a good idea to give them a tap with a hammer.

I found a picture with this pair of wedges before they were used a lot. I'll make new ones anyway! :lol: :lol: :lol:

thanks for the help everyone! It is good to see some fellow maritimers in here! . i stilll have a question or two.. Is it possible to remove the rear wheels without first taking off the wheel weights.. in pics i have seen it doesnt look like there is enough clearance to get a socket on the axle bolts with the wheel weights in place. and i figured if i took the weights off first it would be easier to take off the tires (less weight). i am gonna use the 2x4 method of taking off the weights first.most of my wrenches are metric so i was gonna borrow my fathers tools when i go up to take off the tires and from what i gather the bolts i have to remove are somewhere between 1/2 inch to as large as possibly an inch for socket size.someone must know the exact size socket i'd need, it would be a big help.. thanks again for you help
 
ummm one more quick question..when you say to wedge the front axle.. is this different then wedging the front tires like when you jack up a car??
 
Jamie,

The socket size you'll need to take the wheel off is 3/4". The wheels will come off with the weights still attached but be careful since your wheels both weighted and loaded.

Jamie..

I don't think I would take the tires off with the weights still on it.. but that is just me. An accident waiting to happen. Do the work safely.. take the weights off first. But that is just my opinion.

NOW for the important stuff... I used to have just METRIC to comply with our Canadian compliance with the world standard.. but guess what... :roll: :?: :?: :roll: :lol: 100% of all parts on a Farmall Cub are SAE !!. Do what I do.. go visit Princess Auto... especially since they always have wonderful sales .. and their tools although not Snap-On, are pretty good. My tool box is well filled now......

As for the sizes of the bolts you are interested in.. they are in the TC-37 series parts manuals on the server. :!:
 
Wedging the tires stops a vehicle from rolling. Wedging the front axle stops the Cub from flipping over. Similar but different!

The Cub is an off-set design, meaning the engine IS NOT on the centerline of the tractor. This makes one side of the tractor much heavier than the other. However, the front axle pivot IS on the centerline and the engine will to succumb to the effects of gravity if you give it a chance. This occurs when you have one or more wheels off the ground and someone leans against the hood or you're wrestling with removing or installing stuff or some kids come bouncing through or . . .

George's picture shows where to insert the wedges and the extent of the offset - that's a lot of weight hanging on one side of the pivot. Locking the front axle pivot with wedges will stablize the tractor.
 
A couple tips from experience :shock:

Don't make the wedges too thick(triangle shaped), they'll squirt out easy under pressure.

Cut your wedges with the grain for strength(like George's picture). If you cut the wedges "cross grain" they will break off piece by piece, just when you don't want it to :shock:

I'm not a wood expert, so I learned the hard way :D

Somebody mentioned removing the wheel with the weight still attached.
I've done that a few times when I was changing tire width and it seemed pretty easy and logical to me. Of caorse you have to do that if you are putting the weight on the inside of the wheel. Last yr while pulling logs up a hill I spaced my tires out as far as they would go with the weights on the inside. That was the most stable config I figured there could be.

That brings up another thing. What I was doing, pulling those logs was right on track for a flip over. But you know, the little Cub never offered to raise in the front. Even when a log would catch suddenly as it came up the hill, which happened quite freqently, It never even felt light in the front. All it would do is spin out. Can a Cub flip? My other tractors---OH YES! They have gotten light or up in the air many times, But the Cub never.
 
I would say if you hook to the drawbar it won't, but hook anywhere up higher and look out. You're asking for trouble.

There was a post about this flip-over topic a few months ago.

Rick
 
Ye Rick, there was quite alot of talk about it. And the larger more powerful tractors seem to me anyway, to be more subsebtimal to it. The Cub however has never givin me any trouble. I do alway hitch to the factory bar, never higher.
