PROBLEM
Show/hide table
| The existing exhaust system on certain 12M 2, 120M 2, 140M 2, and 160M 2 Motor Graders may contain an incorrectly manufactured venturi. If the venturi is incorrectly manufactured it may result in excessive exhaust heat being transferred towards the pre cleaner. The misdirected exhaust heat may lead to deterioration of certain hoses, discoloration of the exhaust check valve and deformation of the pre cleaner. Reference Image 1. This issue potentially affects the machines that were not originally ordered with the Snow PreCleaner Group. |

ACTION REQUIRED
Show/hide table
| Inspect the existing exhaust system for any signs of heat damage present at the pre cleaner assembly, hoses, and exhaust check valve. If there is heat damage present remove the existing 350-1282 Venturi and replace it with a new 443-8156 Verturi. Reference Image 2 for the venturi location. In certain instances machines may have been modified per the instructions provided in TIBU7763, "The Air Cleaner Housing and Hoses May Experience Heat Damage On Certain M Series 2 Motor Graders". If a machine has been modified in an attempt to prevent damage to the pre cleaner assembly by plugging off the venturi line that machine may be reworked under this service letter. When updating a machine determine the original pre cleaner group and replace any damaged components as required when installing the new exhaust venturi. Note: Groups 1 and 2 do not have the 1W8620 Check Valve (3) shown in Image1. |
