SAFETY - PRODUCT IMPROVEMENT PROGRAM FOR INSTALLING AN ADDITIONAL HOSE ON CERTAIN 16M MOTOR GRADER FUEL FAST FILL VENTS
MODELS INVOLVED - 16M Motor Graders
Dear Caterpillar Product Owner:
A 1226908/">122-6908 Hose needs to be installed to the vent assembly within the 277-3628 Lines Gp-Fuel - Fast Fill System on the products listed below. When the system is venting, the existing vent without the hose could allow fuel to spill onto unwanted areas on the machine, including the turbocharger. This, in conjunction with other factors and circumstances, may result in a risk of personal injury or death. You will not be charged for the service performed.
Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service.
Please refer the dealer to their Service Letter dated 26Aug2010 when scheduling this service.
We regret the inconvenience this may cause you, but urge you to have this service performed for your added safety and satisfaction.

Rework Procedure
The following procedure is written to provide directions for adding a 8Y3795 Boss to the fuel tank support assembly on 16M Motor Graders, to accommodate the 277-3628 Fast Fill Adapter Group.
PRELIMINARY
Welder Qualification/Safety
All welders must be qualified for fillet and groove welding as outlined in the current ANSI/AWS D1.1, D14.3. The welding operator must also have used the welding process during the last six months or be re-certified for this process before welding. Personal protection should be provided to assure that total weld fume in the operators breathing zone is within safe limits.
Electrode /Characteristics
The SMAW process shall be used with E7018 (ANSI/AWS A5.1) welding electrode. The weld deposited by these electrodes will have the following minimum mechanical properties:
TENSILE STRENGTH 480 MPa (70 KSI)
YIELD STRENGTH 400 MPa (58 KSI)
ELONGATION 22%
IMPACT TOUGHNESS 20 FT LBF @-20F (27J @-18C)
These are low hydrogen electrodes and must be stored in an electrode oven at 120 degrees C (250 degrees F) when not in use. If the electrodes get damp, scrap or recondition to manufacturer's specifications.
The following chart relates to the electrode diameter and approximate current settings for welding:
DIAMETER AMPS
3.2MM (0.125?) 1/8? 70-140
4.0MM (0.156?) 5/32? 110-180
4.8MM (0.166?) 3/16? 190-270
Use the direct current electrode positive (DC reverse polarity) polarity setting and remove the slag after every pass. The weld pass volume shall not exceed two times the electrode diameter.
As an alternative process the FCAW process may be used with E71T-1 (ANSI/AWS A5.20) welding electrode and the manufacturers specified shielding gas(es). The weld deposited by these electrodes will have the following mechanical properties:
TENSILE STRENGTH 480 MPa (70 KSI)
YIELD STRENGTH 400 MPa (58 KSI)
ELONGATION 22%
IMPACT TOUGHNESS 20 FT LBF @-20F (27J @-18C)
Welding parameters will vary due to weld position and manufacturer of the welding electrode. For
