Introduction

The problem that is identified in the technical information bulletin that follows does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.

Problem

Reports have been received from the field of improper functioning of the 150-5030 Air Filter Change Indicator for the air cleaner groups on some 773F, 775F and 777F Off-Highway Trucks. You must check the indicators for the air cleaner groups daily on the machine. The 123-0275 Fitting on the air cleaner groups is incorrectly installed. This causes the hoses to the indicators to be pinched. The indicators do not properly function.

Solution

For the 773F machines and the 775F machines, you must add two 3B-6552 Elbows to the 227-9992 Air Cleaner Gp . For the 777F machines, you must add one 3B-6552 Elbow to the 243-5157 Air Cleaner Gp .

Use the following procedure in order to add the elbows to the machines.
