FLYWHEEL GP 9Q6550 - Caterpillar

4. Measure the distance between the top surface of the circle and the drawbar. If the distance is less than 1.5 mm (.06 in) replace the wear strip.5. Inspect the wear strip and drawbar. The wear strip should be in running contact with the circle. If they are not in contact, shims can be used. Refer to Special Instruction, SMHS7185 for installation procedures. No more than two shims are to be installed under any one wear strip.Circle to Shoe Clearance
Rotate the blade 90 degrees to the frame. Install the C-clamps before lowering the blade to the ground. 1. Install two C-clamps to the front of the circle and the drawbar. Tighten each clamp until the wear strips are in contact with the top of the circle and the bottom of the drawbar.2. Lower the blade to the ground. Stop the engine. The wear strips should be in contact with the circle and drawbar, 360 degrees around the circle. 3. Make sure the shoe mounting bolts are tight and the wear strips are completely seated in the shoes. 4. Measure the clearance between the bottom of the circle and the top of the shoes wear strip. Maintain a clearance of approximately 0.5 mm (.02 in). Add or remove shims between the shoes, as required, to maintain the proper clearance. The proper clearance will permit free rotation of the circle through 360 degrees of rotation.Adjust one shoe at a time. 5. Loosen the nuts (2) and remove the mounting bolt (1).6. Add or remove shims as required.7. Install the mounting bolt (1) and tighten the nuts (2).8. Check the clearance after each shoe has been adjusted for proper clearance. Make adjustments if necessary. The circle must rotate freely without binding after all adjustments have been made.Circle Pinion and Circle Shoe
The pinion and circle tooth engagement is determined by the circle shoe adjustment. To reduce wear to the pinion and circle teeth and to improve accuracy of adjustment, clean the circle and pinion of dirt and abrasive material. Apply clean lubricant to the pinion and circle teeth after the adjustment has been made.1. Rotate the blade 90 degrees to the frame and lower the blade to the ground. Slowly move (inch) the machine forward and apply the parking brake, this will hold a light load between the front shoe wear strips and the circle. Stop the engine. 2. Measure the clearance between the bottom flange of the pinion and the inner machined surface of the circle. If the clearance is less than 50.0 +2.5 -0.5 mm (1.97 +.10 -.02 in.) adjust the clearance. 3. Loosen the front shoe mounting bolt (1), nuts (2) and adjusting nuts (3).4. Loosen the rear shoe mounting bolt and back off the adjusting nuts.5. Turn the front shoe adjusting nuts (3) in or out to obtain a minimum clearance of 50.0 +2.5 -0.5 mm (1.97 +.10 -.02 in.).6. Repeat the procedure for the other front shoe. The front shoes must be adjusted the same.If the correct
