Have you tried http://partstore.caseih.com
It's a completely different interface. So far I like it much better than the pvassociates one. Way less annoying.
It shows you thumbnails of each page so you can find the page you want right away instead of having to guess and reload page after page. It lets you have multiple parts books open at once.
You can click on the part in the picture and it highlights the part in the list. Then you can add it to your shopping cart and get a price on it from your local dealer.
