Rework Procedure


 
Notice: Review the "Parts Ordering Instructions" section below prior to ordering any parts for repairs!

EXCAVATOR INSPECTION AND CLAIM PROCEDURES (For Group 3)

Excavators with factory installed Center-Lock Pin Grabber Couplers that are affected by this Service Letter (verify the Center-Lock coupler S/N) have been included to aid in locating couplers. It is encouraged to call the owner to verify if the Excavator listed still has a Center-Lock Pin Grabber Coupler installed prior to traveling to the Excavator job site.

Because both the excavators with factory installed couplers and the affected Center-Lock Pin Grabber Couplers are listed, two entries may need to be made to get credit for completion of the service letter. Two scenarios exist and the following explains how to make the entries based off of which scenario applies:

1) If the affected Excavator has an affected Center-Lock Pin Grabber Coupler installed on it, submit a Service Letter claim against the affected Center-Lock Pin Grabber Coupler serial number for the actual expenses incurred up to the allowable claim limits. Also a SIMS Report must be filed against the affected excavator S/N with the Description code "NA", meaning "Does not apply ? Inspected" and the comment "Coupler Attached" entered. Refer to Warranty Bulletin No. 1.16, section "Dealer Inability To Complete A Safety or Priority PIP Rework" for further details. No travel time, mileage, or labor should be claimed against the affected excavator serial number.

2) If the listed excavator no longer has an affected Center-Lock Pin Grabber Coupler installed on it, actual travel time and mileage incurred, along with actual labor up to 1 hour may be claimed against the affected excavator Serial Number. When no travel time or labor exits (such as when the customer is called instead of sending a technician out to inspect if an affected coupler is present on the excavator) and a Service Letter warranty claim for monetary reimbursement is not filed, A SIMS Report must instead be filed against the affected excavator S/N with the Description code "NA", meaning "Does not apply ? Inspected" and the comment "Not Found" entered. Refer to Warranty Bulletin No. 1.16, section "Dealer Inability To Complete A Safety or Priority PIP Rework" for further details.

Note: Couplers that were sold loose for dealer installation will only need to have the service letter claim filed against the coupler S/N. Loose shipped couplers will not have a corresponding excavator S/N listed in the Group 3 Affected Product.



COUPLER REWORK PROCEDURE

Notice: Review the "Parts Ordering Instructions" section below prior to ordering any parts for repairs!

This service letter applies only to the DB-Linkage Center-Lock Pin Grabber Coupler installed on 330D, 336D, and 336E Excavators. All Center-Lock style Pin Grabber couplers can be identified as having the red secondary lock as seen in Image 1.1.1 that is unique to only the Center-Lock product line. The secondary lock is clearly visible from the cab. Other Pin Grabber style couplers are not affected by this issue. Center-Lock couplers on other excavator models are not affected by this issue. Center-Lock couplers on non-DB-Linkage (such as TB-Linkage) 330D, 336D, and 336E Excavators are not affected by this issue.
Image1.1.1
 
1) Order and provide the operator/owner with the Operation and Maintenance Manual SEBU8471-09 (or later revision) "Center-Lock Pin Grabber Coupler". Inform the operator/owner that the Operation and Maintenance Manual now states that a "Hydromechanical Conversion Kit" is required when operating hydromechanical work tools with the Center-Lock Pin Grabber Coupler on 330D, 336D, and 336E Excavators configured with DB Linkage. Inform them that this rework performed under this Service Letter will update the Center-Lock Pin Grabber Coupler and install the Hydromechanical Conversion Kit for use of the excavator and coupler with hydromechanical work tools. The "Hydromechanical Conversion Kit" only affects the coupler hydraulic control system. The machine still needs to be equipped with the proper "Tool Control" hydraulic system to provide the proper flows and pressures to operate a hydromechanical work tool.

2) Remove the Center-Lock Pin Grabber Coupler from the excavator and machine or replace the variable hook, identified by the arrow in Image 1.2.1, and install a Hydromechanical Conversion Kit. Refer the Operation and Maintenance Manual, SEBU8471, "Center-Lock Pin Grabber Coupler" for instructions on how to remove and install the coupler on the excavator. Refer to Disassembly and Assembly, KENR6595, "Coupler Cylinder ? Remove and Install" for the proper procedure to remove and install the coupler hook. Depending on the excavator model, determine the proper Hydromechanical Conversion Kit required and follow the included instructions to install the kit. For correct parts ordering see the "Parts Ordering Instructions" section.


3) Affected Center-Lock Couplers in dealer's inventory should remove the Operation and Maintenance Manual, SEBU8471 from the plastic publications container and replace it with the Operation and Maintenance Manual SEBU8471-09 or later revision. The affected coupler should then have the hook machined. Since there is no machine that the affected coupler is installed on, no further action is required. When the coupler is sold in the future, it will be the responsibility of the customer to purchase the Hydromechanical Conversion Kit if needed for their application. For correct parts ordering see the "Parts Ordering Instructions" section.
Image1.2.1
 
Since this issue affects only couplers used with hydromechanical work tools, customers using these types of tools should receive first priority when reworking the field population.

PARTS ORDERING INSTRUCTIONS

Hooks:

NOTE: Due to very limited availability of replacement 423-7098 and 423-7097 Hooks, the priority should be machining the existing coupler hook per Service Magazine SEPD1525, "DB Linkage Center-Lock Quick Coupler Hook Ramp Profile Modification for 330D, 336D, and 336E Excavators".

If the Hook Assembly cannot be machined due to reasons such as wear, inadequate facilities or remote locations, the Hook Assembly can be replaced. The affected couplers could be installed on a 330D, 336D, or 336E excavator equipped with the DB Linkage. Determine if the affected coupler S/N is contained in "Group 1" or "Group 2" and only if necessary order the "Hook As" for the group the coupler S/N falls into. The "Hook As" are put on a parts ordering freeze due to limited availability. Prior to ordering the hook, provide your GCI Service Tech Rep your dealer code, the part number of the hook, quantity and the reason of ordering and get approval of ordering.

For reference:

The wide body 292-4152 Center-Lock Pin Grabber Coupler contains the 318-2552 Hook that should be machined to convert it into a 423-7098 Hook per Service Magazine SEPD1525, "DB Linkage Center-Lock Quick Coupler Hook Ramp Profile Modification for 330D, 336D, and 336E Excavators", and may have been factory installed on 330D, 336D, or 336E Excavator ordered with arrangement number 392-7794 or 384-9786.

The narrow body 318-7130 Center-Lock Pin Grabber Coupler contains the 318-8307 Hook that should be machined to convert it into a 423-7097 Hook, Service Magazine SEPD1525, "DB Linkage Center-Lock Quick Coupler Hook Ramp Profile Modification for 330D, 336D, and 336E Excavators", and may have been factory installed on 330D, 336D, or 336E excavators ordered with arrangement number 346-1996 or 356-8110.

Hydromechanical Conversion Kit:

Only one "Kit-Hydraulic", referred to as the Hydromechanical Conversion Kit, is required per excavator and is determined by the excavator model that the Center-Lock Pin Grabber Coupler is installed on. Use the following to determine which Hydromechanical Conversion Kit is required:

- 330D and 336D Excavators have the coupler control valve located in the excavator pump compartment and therefore require Hydraulic Conversion Kit 422-2496 (installation instructions GEHS0445).

- 336E excavators have the coupler control valve located at the boom foot and therefore require Hydraulic Conversion Kit 417-4689 (installation instructions GEHS0431)

If the Hydromechanical Conversion Kits are not available, order the piece parts listed in the kit installation instructions.

Note: A very limited number of 336D's near the end of the production run may have the coupler control valve located at the boom foot. For these excavators either replace the 266-1135 hose assembly with the 349-7718 hose assembly, or order and install the 417-4689 Hydraulic Conversion Kit instead.

Operation and Maintenance Manuals:

No special ordering limits or processes apply. The same Operation and Maintenance Manual, SEBU8471 is used for all affected couplers (note that they are not needed for the excavator population listed in this Service Letter). Order paper copies per your normal ordering process.
