Model 37 ih disk bearing?

I acquired what I think is a model 37 IH 12foot disk. One of the bearing housing seems to get a little warm even tho it has plenty of grease. On our other brand of disks they use a large seal bearing tho this model looks different. On the housing I see the number PB3089. I would like to get new bearings before tearing it apart. Any help would be most appreciated. Thanks Bill

According to the part number that you listed, your disk was made between 1955 - 1961.

Here is a picture of the gang assembly.

You should be able to get the bearings from your Cash IH Dealer, BUT they may be somewhat costly.

You can go to the link below and look up the parts for your disk by typing 37 in the search field, then after pressing the enter button select the one that reads: 37 INTERNATIONAL HARVESTER DISC HARROW.

You can still order new casting and sleeves at about 160 bucks a set.I just got some used ones for 35 a set.I was told that you can use the new style brackets and change over to roller bearings if you plan on keeping the disc for awhile. Check the case website for a parts breakdown.

Yes you can change the brackets that hold the bearings. You would need the brackets from a 1962 & newer model disc. Plus you would also need some additional parts as showm in this picture:

They are the BEARING SUPPORT #8.

Both the SPOOLS #11 & 15 (they must be the ones for your disc's spacing.

The TUBE for the center of the bearing #12 (again it needs to be the one for your disc's spacing).

And the BEARING #18.

Your disk should have 1 1/8 square gang bolts, you can get the newer style bearings like the one below:

From a supplier called The Big Bearing Store, (for a sample picture see part #ST491A)on their site.

The #ST491A sells for $15.75 on their site, or they list them on eBay for $11.75 each. To find them on eBay do a search for item #3877223946.

My local IH dealer wanted $31.50 each for the same bearing (and it it had MADE IN CHINA stamped on it).

The link to their site is below.

The 37 disc was avaible with either white iron (greasable) or sealed bearings in both a 7" and 9" disk spacing, we always greased the white iron type bearings till grease came out of them and usuealy both morning and evening and sometimes more, if you hear one start to sweek stop and grease, you cannot over grease the white iron type except the cost of the grease

Do your bearings use 2 halves held around the spool with a U bolt? These are the older style of bearings. I don't know if IH can get them anymore, but I have some I saved out of an older disk. I am not sure of the part number, though. Are you talking really HOT or just warm? After a little use I would think they would all get a little warm to the touch because they are just 2 pieces of cast iron or whatever running inside each other, more like a bushing than a bearing. Don't overgrease these to keep them from making noise, too much grease holds the dirt inside them and wears them out much faster.
