how do i find catalog

how do i search item #'s in catalog

A bit more detail of what catalog you are asking about and an idea of what you are trying to search for, would help get you a better answer.

If its a paper catalog, there's an alphabetized index, usually in the back. If its an online catalog, there's a search box somewhere near the top of the page, and there might be an index page or table of contents near the first page.

I assume you must be talking about the YT store.
Easiest way is to just click the rectangular box at the
top of the forums that says ..Tractor Parts.. Then
select anyone of the tractor brands that comes up in
the drop down. That will take you into the parts
catalog. Then at the top there is a Search box that says
..What can we help you find?.. When you click in it a
drop down pops up but just ignore that and type in the
number you want to search it will override what the
drop down wants you to select. Then hit enter or click
the search magnifying glass on the right of it.

I have bought very few parts from YT but I have long
thought they would sell a lot more parts if their search
function worked better. However, they must have done
some upgrades because I just tried a couple of part
numbers of two different manufacturers and behold it
worked. Of course I got the part numbers out of one of
the descriptions in the actual store offerings. There
was a time that you could simply type in ..Farmall H
Valve Cover gasket.. and the search would say it could
not find your parts. As I said they apparently did some
upgrades because that now produces some legitimate
returns.

Thanks,It worked!!
