Looking for info on a Cub in N. Florida

[PFord]

Hi,
The Cub looks good in your pictures.

Thanks. I took a couple more pics today. Needs a bath, but I like the look of it pretty well so far.

I remove the spark plugs with the hood on, using a 7/8", 6 sided, deep socket, and a 3/8" or 1/2" drive ratchet up under the hood.
The ratchet has to go lengthwise with the engine.
Wear good leather gloves so you don't bang your hands on things.
Before removing spark plugs, clean all dirt from around their bases so it doesn't fall in the engine.
Dirt can be packed in the side you can't see from the left side of the Cub. Use a screwdriver, and run it around behind the plugs, and scrape it loose.
Compressed air will blow it out when loosened, wear your safety goggles when using the air.

I didn't try this but will this week. Need to get a deep 7/8 socket. And good call on cleaning all the way around the plug hole. I wouldn't have thought to do that. Thank you. And now I've gotta drag the compressor out too! LOL!

I guess you meant they are so tight you couldn't get them loose with the box end wrench.
If they are that tight, the ratchet up under the hood might or might not loosen them, that is for normal conditions, when the plugs come out easily.

No, I just meant I couldn't get onto them with the wrench. Socket should work ok.

My Cub has the underaxle exhaust, it's not hard to remove the transmission oil level plug.
I use an 8" Crescent wrench to remove the plug.
The trans oil drain plug is at the bottom of the trans, visible from under the platform.
I would change it's oil.
Cubs commonly get water in the trans, from rain, or condensation in the housing over time.

I'll see if my long crescent can get onto the plug from above. I was able to get onto it with a socket and a universal joint, but I need the correct socket.

The operator's manuals for Cubs beginning in about 1958 say to use Hy-Tran fluid in the trans and final drives.
Nowadays it is Case IH Hy-Tran fluid.
It is sold at Case IH dealers.
It is used for the Touch Control too.
There are other brands, be sure it works with IH tractors before buying one.

I need to learn more about this Hy-Tran fluid. I was aware people used them in the hydraulics, but not the transmission. Never heard that mentioned before. I downloaded the 1974 manual so I'll go through that a bit more thoroughly. I don't believe I have a Case IH dealer nearby so I'll have to see about sourcing that.

The manuals in Rudi's Manuals say you can use gear oil if you want in the gear housings, before serial number 248125.
They don't have every year of operator's manual there.
That is at the top of the page at Cub info.

Thanks for the heads up. I'd found the manuals and that's a great help. Guess I'll be doing some light reading tonight!

I use the (12-point) box end of a combination wrench to remove spark plugs. Put the wrench on so it angles down away from the plugs. A couple of them you may have to go in 1/12th increments to get started. Once they are loosened, it goes quicker.

Yep, that's what I am going to try. Thanks!

I have same problem with the cub and Super C as well as the JD plugs so I ground down deep socket exteriors until they fit

You should be able to get the sparkplugs out and in with a 7/8 box wrench.

Nope. Didn't work. I tried.

It didn't work for me because I was trying to use the box end with half of it sticking out from the hood. When the suggestion was made of using the wrench with all of it under the hood going parallel to the motor instead of how I was doing it, I thought that might work.

Be careful not to break off the tops of the other spark plugs while doing this. I know it’s cramped for space in there.

Cramped is an understatement!

As it turns out, the 7/8 wrench still didn't work for me. However, a friend loaned me a 7/8 deep socket and that seems to be going better. I got #1 and #2 changed. I'll try the other two later. They look to be a bit more challenging.

Thanks for everyone's advice and assistance.

[PFord]

Well,

I'm a bit embarrased to admit that working from the RIGHT side of the tractor was MUCH easier. At least for Cylinders 3 & 4. A deep socket 7/8 was all that was required and it was as easy as you please.

Sigh, so much to learn still. Thanks everyone.

I use the wrench pictured to remove plugs. Works well.

I don't have any of those and asked my friend who literally has a 2-car garage FULL of tools if he had any and he said no. That is JUST what I was looking for wrench wise, but wasn't positive it would work. Thanks for confirming they do.

At least now I have a couple ways to solve my problems, and hopefully I won't need to change the plugs for a few seasons.

That is exactly where the name Hy-Tran came from. "Hydraulic" and "Transmission" combined names for a dual purpose oil.
It is worth knowing that Case IH changed their manufacturer of Hy-Tran and it seems to be a different oil now. You may be better off with something that states it is compatible.

[Don McCombs]

If you choose to look for an alternate fluid, you want something that is MS-1207 or MS-1209 compatible.
