The latest version of the manual was published in November 2010. Some of the part numbers have changed since that time. Changes are noted in the below marked-up pdf copy of the manual (click on the link below to view or download). A number of the o-rings were Buna and are now Viton.
It is often preferable to order an o-ring kit rather than individual o-rings. Here are the available o-ring kits. See notes below the table for types of recommended grease.
