6 Super Service Ride Control & Ride Control Trucks 70, 100 & 125 Ton Capacity Proper functioning of the Super Service Ride Control and Ride Control Trucks is dependent on the satisfactory condition of the control elements. Although the life expectancy of these cannot be predicted in terms of years due to the many service variables involved, they function as friction snubbers so some wear is inherent in their action. Wear in such a system can take place on: 1) the column friction plate, 2) the shoe face, 3) the shoe slope and 4) the bolster shoe pocket slopes. These are shown in the figure at the right. In all cases the wear is such as to permit the shoe to rise in the pocket with a consequent relaxation of the spring and a reduction in the "column load". Hence, A MEASUREMENT OF SHOE HEIGHT IS A COMPREHENSIVE MEASURE OF TOTAL SNUBBING ELEMENT WEAR. 1 The most accurate method of measuring shoe height is with a yoke type gauge, page 8, or shoe height gauge, page 9. Both drawings are fully dimensioned for manufacture and contain instructions for use. Note that this measurement can be made with the car light, loaded, or partially loaded. With Ride Control Trucks manufactured after mid 1976, built in visual indicators are provided, and are also capable of indicating total wear and are also independent of the load in the car. See page 7, for proper use of these visual indicators. All Super Service Ride Control Trucks have these visual indicators. In addition to both of these, a limit of wear groove is cast into the shoe face. This, when it is reached, indicates a need for shoe replacement based on shoe face wear. (See page 18) (1) Reduction in "Column Load" can also result from a decrease in Ride Control spring capacity due to springs taking a permanent set. Control spring free heights should be checked as shown in instructions on page 44. DATE OF ISSUE 1/1/94 (REVISED 3/1/95) RC 6

10 Disassembly of Super Service Ride Control and Ride Control Trucks The first step in dismantling must be to retract and pin back the friction shoes using either of the methods, hydraulic or manual, shown on drawing (page 11). Both methods require clearance for insertion of the retraction blade between the top of the shoe and the underside of side frame top member. If the shoes are badly worn, or the truck is of the low profile or low level type, this clearance may be inadequate without a load on the truck bolster. In such cases, it is frequently more convenient to place a block between the top of the bolster and the side frame before removing the weight of the car. Of the two methods, the hydraulic is the preferred (though more demanding of working space). Its construction is detailed on drawing , pages 14 and 15. With the shoes retracted they should be pinned back by use of a 5/8" x 6" long assembly pin. (Longer pins with a hook eye are preferred by many railroad and carbuilding shops.) With all shoes pinned back, remove the truck bolster from the side frames in the usual manner. To remove assembly pins, friction shoes and springs from the bolster, use any of the methods shown on page 12 (drawing ), page 13 (drawing ) or page 16 (drawing ). WARNING Unless restrained, friction shoes and control springs will be propelled out of the bolster pockets when released, potentially causing serious injury. Inspection and Repairs Repairs or replacement may be required to any one, or a combination of parts including: 1. Slope surfaces of bolster pockets 2. Bolster gibs 3. Side frame rotation stop lugs (if present) 4. Side frame columns *5. Replacement of worn or broken friction shoe castings *6. Replacement of missing, broken or worn side frame column wear plates *7. Replacement of control springs * Should one element at a bolster end require replacement, it is important that all companion elements at the same end also be replaced.

11 Method Of Disassembling (1) INSERT FRICTION SHOE DEPRESSOR, AS DETAILED ON DRAWING , BETWEEN TOP MEMBER OF SIDE FRAME AND TOP OF FRICTION SHOES. ACTUATE DEPRESSOR TO COMPRESS RIDE CONTROL SPRINGS UNTIL RETAINING PINS SHOWN A CAN BE INSERTED. IF NECESSARY, BLOCK BETWEEN SIDE FRAME AND BOLSTER SPRING SEATS TO PREVENT LOAD SPRING DEFECTION. (2) RAISE BOLSTER AND REMOVE LOAD CARRYING SPRINGS. WARNING When actuating depressor keep hands clear (4) AN ALTERNATE METHOD OF INSERTING RETAINING PINS A IS TO INSERT SHOE RETRACTOR, AS DETAILED IN FIGURE 5, BETWEEN TOP MEMBER OF SIDE FRAME AND TOP OF FRICTION SHOE. USING AN OVERHEAD CRANE OR FORK LIFT WITH A MINIMUM CAPACITY OF TWO (2) TONS, LIFT VERTICALLY AS ILLUSTRATED TO COMPRESS RIDE CONTROL SPRINGS UNTIL RETAINING PIN A AT THAT POSITION CAN BE INSERTED. REPEAT OPERATION AT THE OPPOSITE FRICTION SHOE TO INSERT THE SECOND PIN A. (3) LOWER BOLSTER AND REMOVE THRU LOWER OPENING OF SIDE FRAME. WARNING Because forces of 6,000 pounds potentially can be developed in using either of these devices, it is imperative that they be used as illustrated and all safety precautions be followed. If devices are not used as illustrated or in an otherwise unsafe manner, serious personal injury could result. It is imperative that all welding be done on devices in accordance with ANSI/AWS D , or later, to ensure quality and strength, and that all materials incorporated in the assembly be of a quality and strength to maintain its integrity. Frequent inspection of the devices should be made for the purpose of identifying any weld or material deficiencies which, if present, should be corrected before resuming utilization of the device. WARNING Friction shoes are spring loaded and will eject forcefully from pocket causing serious injury if pins are removed before bolster is installed into bolster opening of side frame. Only remove pins after the bolster is installed into the bolster opening of the side frame. WARNING Improper installation of friction shoes may cause serious personal injury and/or damage to the shoes. Never strike friction shoes with hammer, or other like tool, since this could cause the shoes or tool to break, and pieces could become airborne. Always use a fixture and constant pressure to install shoes into pockets. (5) SHOE RETRACTOR REVERSE THE ABOVE PROCEDURE FOR ASSEMBLY. AFTER ASSEMBLY, IT IS IMPORTANT TO REMOVE ALL RETAINING PINS TO RELEASE FRICTION SHOES FOR PROPER PERFORMANCE OF TRUCK DATE OF ISSUE 1/1/94 (REVISED 2/1/98) RC 11

17 Recommended Inspection And Repair Procedures This Maintenance and Repair Manual incorporates all recommendations as covered by AAR Standard M 214 for the repair and maintenance of ASF s Super Service Ride Control and Ride Control truck elements. Also included, are many gauges not required by the AAR but deemed necessary by ASF for repair of these trucks. The following procedures and wear limits are recommended for repair of the Super Service Ride Control and Ride Control elements for trucks of 70, 100 and 125 ton capacity: A. BOLSTER POCKET SURFACES 1. WEAR DETERMINATION Determine the amount of slope wear using angle surface contour gauge (page 20). With this gauge in position, if a 3/16 shim can be inserted between gauge and the slope surface at any point, repairs to this surface should be made. If a 1/4 gap exists at or above the scribe line on the gauge, and increases to no more than 3/4 at the top of the bolster, the wear is within the limits of repair. If a gap greater than 1/4 exists at or below the scribe line on the gauge, the wear is not within repairable limits. NOTE: When a fin or protrusion has been formed due to wear, it is to be removed prior to gauging. 2. REPAIR OF AS CAST SLOPE SURFACES Worn slopes should be resorted by the puddle weld method shown on drawing (page 21). Before welding, pocket construction point gauge (page 25) or (page 27) can be used to determine amount of weld material required. Check flatness and alignment of both surfaces using winged clearance gauge (page 23). An alternate procedure is to insert a winged friction shoe casting to the full depth within the pocket. If a shoe is used, some casting clearance is essential as a snug fit could cause binding in service. 3. REPAIR OF SLOPE SURFACES HAVING WEAR PLATES Remove and replace all broken or cracked slope surface wear plats. Repairs should be in accordance with drawing (page 22). Check flatness and alignment of both surfaces using winged clearance gauge (page 23). An alternate procedure is to insert a winged friction shoe casting to the full depth within the pocket. If a shoe is used, some casting clearance is essential as a snug fit could cause binding in service. 4. REPAIR OF SLOPE SURFACES INTENDED FOR APPLICATION OF SLOPEGARD WINGED FRICTION SHOES Repair of bolster slope surfaces for application of Slopegard Winged Friction Shoes is dependent of the pocket design and the amount of wear, as follows: A. AS CAST BOLSTER SLOPES Rebuild to new conditions per drawing (page 28), or grind worn surfaces per drawing (page 30). If ground, limit of wear on bolster slopes should not exceed 3/16. B. BOLSTER SLOPE WEAR PLATES Remove and replace all broken or cracked slope wear plates in accordance with drawing (page 29) or remove slope wear plates and grind smooth per drawing (page 29). NOTE: The above optional procedures are for Ride Control truck bolsters only. Super Service Ride Control truck bolsters are to be repaired per drawing (page 28) or drawing (page 29) only. The proper Slopegard Winged Friction Shoe is to be applied depending on the bolster slope repair per chart shown on page 43. NOTE: Rebuilt slope surfaces must have a minimum surface finish of SCRATA Level H2. NOTE: Bolster slopes are not to be lubricated when Slopegard Friction Shoes are applied. DATE OF ISSUE 1/1/94 (REVISED 2/1/98) RC 17

18 Recommended Inspection And Repair Procedures (Continued) 5. REPAIR OF SIDE WALL If side wall wear is 1/8 or more, restore by using the puddle weld method shown on drawing (page 21). 6. REPAIR OF BOLSTER GIBS Bolster gibs may be restored by the puddle weld method or removed flush with the casting surface and a separable gib welded in place. Gauges , and shown on pages 24, 33, and 34 will be required to ensure proper dimensions. It should be noted that bolsters cast prior to 1987 may require the inner gib trimmed and the outer gib build up to suit these gauges. For certain designs, the outer surface of these inner gibs must also be built up to provide a minimum 5/8 anti rotation stop lug contact surface. See drawing (page 24) for procedure. With gauge (page 24) in place, a 3/32 maximum shim must not go between gauge and either outer AAR Standard M 214 allows standard Ride Control bolsters cast prior to January 1, 1987 to be rebuilt to the previous 5/8 outside, 1/4 inside column gib clearance. Although allowed by the AAR, ASF recommends these bolster gibs be restored to the latest standard of 1/2 outside, 1/2 inside gib clearances. See drawings (page 24) and (page 33) for gauge drawings. 7. BOLSTER ROTATION STOP GIBS Using gauge shown on drawing (page 31), move gauge to one gib and measure distance between opposite gib and gauge. If measurement indicates 1/4 or more clearance, restore gibs to nominal new conditions with welds as shown on drawing (page 21). Both inner gibs may require rebuilding to ensure proper centered fit into side frames. 8. REPAIR OF BOLSTER LANDS (WIDE LAND) With gauge shown on drawing (page 32) in place and moved to one side, repair by the puddle weld method if a 3/16 shim can be applied at the opposite land surface. 9. INSPECTION AFTER REPAIR After repairs are completed, recheck using gauges previously used for determining amount of wear. See page 3 for complete list of bolster gauges as covered in this Maintenance and Repair Manual. B.

Replace all friction shoes if the limit of wear indicator groove is obliterated (see page 8). 3. Replace Slopegard shoes if pads are broken or missing. Friction shoes normally would not be replaced until the wear indicator groove is obliterated, but replacement is recommended with 1/8 or less remaining to ensure adequate service life until next repair period. IMPORTANT To ensure proper function if one casting is replaced due to wear, the opposite casting in that bolster end should also be replaced. DATE OF ISSUE 1/1/94 (REVISED 12/16/08) RC 18

19 Recommended Inspection and Repair Procedures (Continued) C. CONTROL SPRINGS 1. Replace all springs which do not meet the minimum free height specified on drawing (page 44). 2. Replace all control springs not in accordance with latest standard for increased column pressure. See drawing (page 44). D. SIDE FRAME COLUMN NOTE: Ride Control Springs used on 70 ton low level D5 trucks differ from standard due to car design and usage. These coils must be replaced in kind. 1. FRICTION PLATES Many styles of side frame column friction plates have been used during the time Ride Control and Super Service Ride Control Trucks have been furnished. These include welded only (various styles), bolted only (1/2" & 3/4") and combination of welded and bolted. A great number of the early styles have not proven satisfactory. In addition to replacement of friction plates that are cracked, broken, or worn below 1/4" in thickness, representing 1/8" wear from 3/8" nominal new, we recommend plates be applied using two 3/4" diameter fasteners per AAR Manual pages D 121 or D Many of these early style designs will require the drilling of two 13/16" diameter holes in each column. See drawings (page 36) and (page 37) for drilling the side frame column and for application of friction plates to Ride Control and Super Service Ride Control side frames. See drawing (page 38) for Ride Control and Super Service Ride Control column friction plates. 2. COLUMN Using gauge drawing (page 39), check for wear on sides of column. With gauge moved to one column side, if a 3/16" gap exists between opposite column and gauge, restore columns to nominal new conditions as illustrated on drawings (page 36) or drawing (page 37). Rebuilding of both surfaces may be required to ensure proper centered fit with bolster. 3. ROTATION STOP LUGS (IF PRESENT) Using gauge shown on drawing (page 42), check for wear on stop lugs. With gauge moved to one stop lug, if a 3/16" gap exists between opposite stop lug and gauge, restore stop lugs to nominal new conditions so that no more than 1/8" gap exists between opposite stop lug and gauge. Rebuilding of both stop lugs may be required to ensure proper centered fit with bolster. 4. INSPECTION AFTER REPAIR After repairs are completed, recheck using gauges previously used for determining amount of wear. See page 3 for complete list of bolster gauges as covered in this Maintenance and Repair Manual. E. ASSEMBLY Reassemble the trucks by reversing the procedure outlined in "How to Disassemble the Super Service Ride Control and Ride Control Trucks" (page 10). See drawing (page 11). Prior to assembly of friction shoes in bolster pockets, surfaces are to be lubricated in accordance with drawing (page 35). NOTE: Bolster slopes are not to be lubricated if ASF's Slopegard friction shoes are to be applied. NOTE: ASF recommends that cars equipped with Slopegard shoes, in high speed service, also be equipped with constant contact side bearings to reduce possible deterioration of Slopegard pads.
