Jimy:
Let me be one of the first to say welcome to the Greatest Forum on the Net and to our wonderful Cub Family
A good source for parts for a 154 will probably be
JP Tractor Salvage. John and Jamie should have it. If not then possibly Tom over at
TM Tractor Parts might. Either way, one of them will know where to get one. They are good people and a pleasure to do business with.
Many of the questions you might have could probably be answered in some of the knowledge sections/links available at this site. Might I suggest that you read
New Members and Visitors, Please READ. The
Cub FAQ's are filled with a lot of really good general knowledge and the
Cub Info has some good trouble shooting tips. The
Best of H.L. Chauvin puts a humourous yet very helpful tone to fixing your Cub. Also, the [urlhttp://www.cleancomputes.com/Cub/index.html]Cub Manual Server[/url] has lots of info to assist you as well. The Owners Manual and the Parts Manual for the 154 are on the server under Numbered Series Cubs.
A lot of the maintenance issues for the Numbered Series Cubs are very similar to the Farmall Cub and the International Cub Lo-Boy.
Again, Welcome to the Cub Family
