Cat® Service Information System (SIS) is the electronic service tool that covers all information for Cat products from 1977 to today. With 2 million service graphics, 1.5 million parts numbers, and 44,000 parts/service documents, this tool is the equivalent of over 25,000 books; accessible a mouse click away! From SIS, you can identify and add parts to a SIS shopping cart, then bring your cart over to Parts.cat.com when you are ready to order and check-out.
Caterpillar has now released the new SIS 2.0, with enhanced search features, seamless navigation across parts, and a new look and feel that is mobile friendly. Available in 10 languages, give it a try by clicking on “SIS” in the top menu of the Parts.cat.com homepage.
