  • Page 67 Volume 53, No. 8 October, 2006 ® ® Taper-Lock and QD Bushing Installation and Removal ® ® Taper-Lock and QD bushing installation is critical to good belt drive performance. Improper installation can damage the bushing and/or the sprocket/sheave. Sprockets/sheaves are commonly mounted to a shaft with a tapered bushing that fits a mating tapered bore in the sprocket/sheave.
  • Page 68 Note: Do not lubricate the bushing taper, hub taper, bushing bore, or the shaft. Doing so may result in sprocket/sheave hub fracture. DO NOT USE LUBRICANTS 4. With the key resting in the shaft keyway, position the sprocket/sheave and bushing assembly onto the shaft allowing for small axial movement of the sprocket/sheave which will occur during the tightening process.
  • Page 69 ® To Remove TAPER-LOCK Type Bushings 1. Loosen and remove all mounting bolts. 2. Insert bolts into all jack screw holes indicated by dark removal holes in Figure 1 on page 1. 3. Loosen the bushing by alternately tightening the bolts in small but equal increments until the tapered sprocket/sheave and bushing surfaces disengage.
  • Page 70 When installing large or heavy parts in a conventional mount, it may be easier to mount the key and bushing on the shaft first, then place the sprocket/sheave on the bushing and align the holes. Note: When mounting sprockets/sheaves on a vertical shaft, pre-cautions must be taken to prevent the sprocket/sheave and/or bushing from falling during installation.
  • Page 71 RUBBER TRACK OPERATIONS MANUAL...
  • Page 73 GENERAL SAFETY AND ACCIDENT PREVENTION Please ensure all safety precautions and instructions are adhered to when installing, operating and/or performing maintenance on the track systems. Every job is different and a risk assessment and method statement should be conducted and adhered to for any maintenance operation.
  • Page 74 1.5 SAFE LIFTING AND HANDLING OF TRACK SYSTEMS Always check the weight stamped on the identification plate before lifting or moving the track system. For reasons of safety and even weight distribution, always use two chains or slings in the positions shown below. Ensure the adjoining sling which connects the chains to the crane hoist has an adequate load rating.
  • Page 75 1.6 OPERATING PRECAUTIONS When travelling up a gradient, the tracks should be driven forward (i.e. idler first, drive sprocket to the rear). When travelling down a gradient, tracks should be driven sprocket first. Always: • Park the machine on flat, level ground. If it is necessary to park the machine on a gradient, the tracks should be solidly blocked.
  • Page 76 1.7 WORKING CONDITIONS Avoid using the rubber tracks in the following situations: 1. Do not use in marine and seaside environments. Saline air will cause the rubber and the internal steel cords to lose adhesion. 2. Do not keep the tracks in exposed sunlight for extended periods of time as UV rays will shorten the life of the rubber track.
  • Page 77 BASIC MAINTENANCE 2.1 CORRECT MAINTENANCE PROCEDURE In order to maintain the reliability of the track systems, regular maintenance is essential. It is imperative that the tracks are maintained as outlined within this maintenance section. ALWAYS: • Perform maintenance on a level and solid surface. •...
  • Page 78 2.2 MAINTENANCE CHECKS (con’t) After identifying any problems, take corrective action immediately; tighten bolts and nuts to correct torque as per Appendix A, replace damaged or worn components, and refill the oil to recommended levels. WARNING DO NOT operate the tracks with damaged or defective components. Any persistent problem should be reported to the machine manufacturer.
  • Page 79 2.3 CHECKING TRACK TENSION Stop your machine on solid level ground and drive 6 feet (minimum) in a forward direction. Lift the center of the belt up gently and measure the sag on the top part of the track in the longest section of unsupported track as shown below.
  • Page 80 2.4 ADJUSTMENT OF TRACK TENSION Track systems use a grease cylinder to keep each track chain in tension. Screwed into the end of the grease cylinder is a grease fitting, enabling grease to be pumped into the grease chamber tightening the track. If this valve is loosened grease will escape causing the track to de-tension.
  • Page 81 2.4.1 Tightening the Track • Loosen one of the two screws and swing access cover away from access aperture on the side of the track frame (if applicable). • Ensure the grease fitting and grease gun adaptor is clean; ingress of dirt into the grease fitting can result in failure.
  • Page 82 2.4.3 Removing the Track Belt • To remove the track belt first ensure the machine is in a safe flat working area on solid ground. • Lift up the machine and support it with the tracks safely off the ground. •...
  • Page 83 2.4.4 Refitting the Belt 1. Support the machine safely off the ground, fit the new belt over the idler end first. 2. With the idler fully retracted fit the belt over the sprocket. This may require the use of a prybar to walk the belt into place.
  • Page 84 2.5 TRACK DRIVE UNITS 2.5.1 Oil Fitting & Draining Below are the 3-common oil filling/draining configurations: To fill, track the machine until the gearbox casing is level with a plug positioned as shown below. Fill from the upper hole until oil reaches the level indicated. To drain, track the machine until a plug is at 6 o’clock position as shown below.

  • Page 87 3.2 LEAKS AND SEIZURES Many components fitted to the rubber track systems, such as rollers and idlers are lubricated with oil. Regular checks should be made to ensure these components are not leaking and rotate freely when the tracks are driven. Any items such as rollers, which show signs of leaking, or fail to rotate when the tracks are driven should be replaced immediately to prevent damage to the system.
  • Page 88 TROUBLESHOOTING 4.1 TRACK TENSION Track systems use a grease cylinder to keep the track chains in tension. Loss of tension in the tracks can result in the sprocket jumping in the belt lugs, and also allows the belt to run off of the idler/sprocket.
  • Page 89 4.2 LOSS OF DRIVE The rubber track systems are driven using hydraulic motors connected to planetary drive gearboxes. The hydraulic motors are driven using the hydraulics fitted to the machine. Begin by making a visual inspection of the tracks, particularly around the sprocket, idler and bottom rollers where material / objects can sometimes lodge.
  • Page 90 4.3 MANUAL BREAK DISENGAGEMENT OF TRACK DRIVE The drives are fitted with negative parking brakes, therefore when no pressure is applied, the parking brake is locked on. Should the host machine need towing due to loss of drive power, there are two different solutions for towing the machine depending on the gearbox installed. Gearboxes with Mechanical Disengagement Function: If the gearbox is supplied with the mechanical disengagement function, it can be identified by a plug situated on the outer face of the gearbox end cover, shown fig.1 above.
  • Page 91 4.4 LOSS OF PARALLEL DRIVE The rubber track systems are driven by hydraulic track drive units. Drives consist of a hydraulic motor connected to a planetary drive gearbox. Power is relative to the hydraulic pressure and speed is relative to the hydraulic flow from the machine’s hydraulic circuit.
