Randy - I'm not sure but I think that's a hardened roll pin that goes in there.

I called the tractor store and was told it was a 5/16 by 1 1/2" bolt.

First, Image to the greatest forum on the internet, and to the Cub Family. You will find that all the folks on this forum are kind, helpful and just full of Cub info and knowledge. They also happen to be the finest folks I have ever met :!: :D

Well, not having a Numbered Cub.. I have no expertise to help, so I will just rely on the engineers and mechanics at IH.... You should be able to find out what it is.. and I am sure that Big Dog is probably right... in the TC-131 Parts Catalog Revision 8 Index - Power Train Section on the Cub Manual Server :!: :idea: :arrow: :wink: :D Best I can do. I do not have a Service Manual for the 154 yet... hopefully someday, but not yet....

Ok, so here is the spiel Image:

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 are intended to complement the businesses who support the Website.

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.

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

Randy, I'll have to check with my Dad, but as I recall he had a similar problem a few years back with his 154.

Can't recall all the items off the top of my head, but his problem turned out to be a bearing not installed properly? This particular sleeve bearing was meant to be slid onto the shaft, then turned 180 degrees before sliding the assembly together. He (nor did any manual explain this) never realized the problem, kept ruining bearings, shafts, breaking a bolt, etc.

I need to give my folks a call this weekend anyway, and I'll check with him and see if he can provide any further info.
