Randy:
First,
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
I have a 154 and I keep breaking the bolt from the coupler to the input shaft ot the tranny.The last time I used a grade 8 bolt but it also broke
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 
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
:
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
FarmallCub.com 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,
to the Cub Family
