Disc Harrow old disc repair

[cedar21]

Hi. I am trying to repair an old disc I acquired. The disc axles go through two housings that seem as though they should have a bearing, though there is no bearing, just some sort of liner of unknown material. The housing and the liner are round, though the axle is square. Any information on how this works would be much appreciated. I am attaching some photos.

:welcome:
To the TBN forum cedar. Glad that you joined and you came to the right place to get answers.

I have never seen a disc with a square axle before, so I am guessing that the liner had a brass bushing which was popular back in the day.

Pics are too dark to see what you have.
There are a lot of common harrow parts.

Shoot me some pics of the disc gangs, the individual discs themselves and the "space bearing itself. Did your disc axle have a big square nut on the end??? This maybe a considerable older disc. I've junked out some old disc, and it maybe similar to a few I've junked.

Have you looked for tag on the disk for a brand name? I do not think they put a square axle in round housing without a turn bearing in there. Square axle would wear such as brass or wood (years ago) bearing out real quick. It looks like the bearing housings may be worn, maybe too much to keep bearings in there but only way to know if find the right bearings for the disk. Square axles are right common on disc, at least ones up to say 12 feet wide. Measure the size of the axle, nearest 1/8 is what I think you need but they do have 7/8 and 1 inch square axles. You will need the bearing housing for the outside diameter and width or thickness of the bearing. Do not be shocked if you are needing more than bearings. Look at the bearing housing to see if any grease fittings there to know if you need grease able bearings or sealed bearings.

I have looked for a tag on the disc, but no luck there. The housing that the shaft goes though has some sort of rubber looking material, and inside of this appears to be a metal tube. I am not sure that there is enough space in the tube for a bearing. I have seen the housings that come apart and hold a bearing, though the housing on this disc is solid. If there ever were bearings in the housings, there is no sign of any bearing left. There is a grease fitting though.

Good luck

The bearing assembly on the Ford diagram is not the same as the disc I have. I have looked at diagrams of Ford discs (since the disc I have is blue), though so far have not found any diagram that looks like the disc I have.
