Introduction

The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem

A new air filter design is available as a service replacement. The former design is all one piece. The new design has a reusable support frame

Solution

If the 305-0329 Cab Air Filter Element As or the 4I-1278 Cab Air Filter Element is currently being used, the 293-1183 Cab Air Filter can be used as a service replacement. The machines that are currently using the 293-1183 Cab Air Filter , should use the 293-1184 Cab Air Filter Element for the media portion to replace and is a more economical.
