Are the belt pully seals hard to change? It doesn't look like it. Does any one know the # of the seal.
Will need one for a 48 H and a 48 M Wouldn't you know they would both be leaking.

You may need to use a shop press and bearing separator to remove the gear and bearings from the pulley shaft. You may be able to drive them off, but I took the assembly to a shop and had them pressed off and back on. There is not a gasket on the flange that mounts the assembly to the housing. There are shims there to set the gear lash. Be sure you put the shims back like they came out and clean them and the mounting surfaces. Make sure they are absolutely clean when you reassemble but even then, you may have some seepage of gear oil due to there being no gasket, only metal shims. When it's back together, put a pint of gear oil in the fill hole on the belt pulley housing. The transmission lubes the belt pulley bearings, but it takes a while for the oil to sling up there, so you need to add some for initial lube. Oil circulates from the transmission to the belt pulley housing and overflows back to the transmission.

My 2 sons & I just re-did 2 gearcases for their belt pulleys on their "H"s".
Remove the capscrews under the pulley mounting flange and the shaft, spacers, & bevel gear will all slide out with a bit of assistance.
Remove the cap screw on the end of the shaft and all the parts can be pulled off.
I was able to obtain replacement bearings at no cost by going to an electric motor rebuilding shop. If my memory is correct you need a 6210 & 6208 bearing for the drive shaft. Remove any shields so the bearing will now lube itself from the transmission oil. Thoroughly clean all old grease residue before installing the used bearing. Factory bearings run $50 or so for the big one so it can be an expensive affair to replace them. NAPA wanted $45 for the 6210 size.
I have a Case/IH dealer in town (Fergus Falls, MN) so obtained the new seal, felt dust washer, and mounting gasket from them at a very reasonable cost.
Carefully clean the metal spacers and put a VERY light coating of silicone on them just before assembly. Don't mix up the cap screws from the drive gear cover with the shaft cover; they are longer (don't ask how I found out) and will not compress the spacers under the pulley flange.
On the drive gear shaft, just remove the 3 cap screws and pull the unit out. Remove 2 fine threaded cap screws & take the bevel gear & bearing off. It is a 6206 size. Watch out for the shift lever plunger & spring as they will jump out if the lever is moved too far. And this will happen as you clean the gear-case. If you need to replace the steel plug in the back of the gear-case, IH doesn't have it any more. Go to an automotive parts rebuilder and get a 1 3/16" soft plug; it can be deeper (longer) than original. Put the spring & plunger back in place, set the large drive gear on the shift lever. Clean & lightly silicone the spacers and reassemble. The 2 long bolts had copper washers but a dab of silicone will work. Be sure to put them in place in the gearcase BEFORE you slip it into place on the tractor. They won't go in later unless you remove the gas tank or pull the gear-case back out. (I know, experience is a great teacher)
It goes without saying to carefully scrape all old gasket residue off before reassembly. Careful use of a 10" or 12" mill file will do wonders. Use it as a draw file ( sideways motion, not forward & back) to locate any high spots on the metal casting also.
I now have 2 belt pulley gear-cases that work just like new at a very minimal cost. Sorry for the long post, I was a Vocational Engines instructor in my past life and just can't quit teaching!!
Good luck.

I will add this to what Wayne said. A gasket is a MUST! I tried mounting the belt pulley gearbox on my M with just silicone, but then the belt pulley would not go into gear. A gasket was needed to space it up 1/16 of an inch so that the gears would mesh properly. You can buy the proper gasket from CaseIH, or just use a cereal box like I did. :-)
