D6R Track-Type Tractor LGP 4HN00001-UP (MACHINE) POWERED BY 3306 Eng... 2/4 Components of rotating bushing track. (1) Bushing. (2) Inner seals and thrust rings. (3) Outer seals and thrust rings. (4) Pin groove. (5) Inserts. The bushings are located between the track links and are not pressed into the bushing bores. Inner seal and thrust ring (2) and insert (5) are located in each bushing bore. Insert (5) is factory installed and is not serviceable. A portion of the pin boss is extruded (pressed) down and into groove (4) in the end of the pin. The process of pressing the link material helps to retain the pin in the joints. The extrusion process (method) of retaining the pins is a factory assembled procedure. Tools are not yet available to do this type of pin retention in a field repair situation. A welding procedure is available, however, for use in retaining the pins in a field repair of rotating bushing track. The procedure given in this Special Instruction can be used to replace a damaged joint in rotating bushing track (RBT). When this procedure is followed precisely, the joints can be welded without causing damage to the non-metallic parts, including the seals, that are inside the joint. Do not perform any procedure, outlined in this publication, or order any parts until you read and understand the information contained within. Reference: For more detail refer to, Special Instruction SEHS8957, "Repair Procedure for Non- Restrained Seals and Lubricated Track". https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sis... 2020/4/27

Standard tools for the D6H Tractor can be used in the procedure. 1. Inspect the track and locate the dry joint. 2. Follow the procedure given under the topic entitled "Link Section Removal of Damaged Joint" in the reference Special Instruction. 3. Pressing out the pin, sometimes cuts off extruded material from the pin bores. Inspect for loose extruded material in the seal cavities after the pins have been removed. Assembly 1. Use the following Weld Procedure as a replacement for the procedure given under the topic entitled "Link Section Buildup with 8T7780 Track repair Group" in the reference Special Instruction. 2. Equalize the pin projection in each joint to be repaired. Set each joint to zero end play. Weld Procedure NOTE: Equalizing the projection at each end of the pin permits an approximate 6-10 mm (1/4-3/8 in) fillet at each end of the pin. Pin projection (solid end of pin shown). 1. Use an E6011 Weld Electrode to make a weld bead for approximately 120 degree (13 the distance) around the circumference of the pin end as shown. 2. Immediately after the 120 degree weld bead is completed, put a wet paper towel (1U9579 Paper Towel) directly om the weld bead. https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sis... 2020/4/27

Leave the towel in place 3-5 minutes while welding the ends of the other pins. Wet paper towel on the end of pin. 3. The ends of the pins must be cool to the touch before continuing the weld process. Repeat Steps 1 and 2 until the bead covers the entire circumference of the pin ends. Completed weld (end of pin shown). Completed weld (hole end of pin shown). Note the undamaged stopper and plug in the end of the pin. 4. After all welding has been completed, refer to the topic entitled "Link Section Installation" in the reference Special Instruction for the track assembly and joint lubrication information, and for track installation information. 5. For track adjustment, refer to the topic entitled "Recommended Track Adjustment procedure" in the reference Special Instruction. Copyright 1993 - 2020 Caterpillar Inc.
