PSP FOR THE USE OF TWO CLAMPS TO HOLD THE BODY AND FUEL NOZZLE IN POSITION ON 3406, 3408 AND 3412 ENGINES - MAILED WORLDWIDE EXC EPT CANADA, BRAZIL & CACO
The information supplied in this service letter may not be valid after the termination date of this program. Do not perform the work outlined in this Service Letter after the termination date without first contacting your Caterpillar product analyst.
PRODUCT SUPPORT PROGRAM FOR THE USE OF TWO CLAMPS TO HOLD THE BODY AND FUEL NOZZLE IN POSITION ON 3406, 3408 AND 3412 ENGINES, 1252, PS4019 U-74 AU-59 E-47 O-45 TT-12 TA-6 TM-6 This Program can be administered either before or after a failure. In either case the warranty allowances will be the same and contingent damage will not be allowed. The decision whether to apply the Program is made by the dealer. When reporting the repair use "PS4019" as Part Number and "7755" as Group Number. Although products in the field are to be administered as described above, dealers should rework parts stock immediately. Termination Date
September 30, 1986.
Problem
Engines equipped with 4W5719 (3406) or 4W5733 (3408, 3412) Adapter Assemblies use one 4W5717 Clamp to hold the body and fuel nozzle in position. See the Illustration. These adapter assemblies are also used in 0R0977 (3406) 0R0980 (3408) and 0R2659 (3412) Remanufactured Head Assemblies. One clamp does not provide enough force to hold the body and fuel nozzle tight. This permits fuel to leak past the internal parts of the nozzle and cause the nozzle case to bulge or split. This program provides for an additional clamp and bolts to be used with these adapter assemblies. (SEE ILLUSTRATION)
Affected Product
1/850907/01/002
Parts Needed
1-4W5717 Clamp and 2-5P6900 Bolts for each adapter assembly.
Action Required
The new parts should be installed on cylinder heads in parts stock immediately. Only cylinder heads received before this Service Letter need to be checked. The new parts should be installed on products in the field only when the valve cover has been removed for some other repair or inspection. Install the new clamp and bolts 180 deg. from the existing clamp and bolts. Tighten the bolts for the new clamp to 31 +/- 7 N X m (23 +/- 5 lb ft). Check to make sure the bolts for the existing clamp are tightened to the same torque. Then check the torque on the bolts for the new clamp. (SEE ILLUSTRATION)
