Remove the receivers from the scrapers only if necessary. If the receivers are removed, an alignment procedure must be followed for proper operation. The receivers on each side of the rear axle permit bowl angle adjustment for compensation of tire wear or to level the scraper bowl.
1. Remove spring (1). Pull hose assembly (2) from the receiver. 2. Loosen nuts (4) and setscrews (3). 3. Install a strap and hoist on receiver (6). Remove nuts (5) and receiver (6). The weight of the receiver is 82 kg (180 lb). The following steps are for installation of the receiver.4. Put receiver (6) in position and install nuts (5).5. Tighten setscrews (3) and nuts (4).6. Put hose (2) in position and install spring (1). After the brake assembly and spindle are installed, the receivers must be adjusted using the following procedure:a. Park the scraper on a flat surface and put the bowl in position so the cutting edge is approximately 152 mm (6 in) from the ground. Check the air pressure in the scraper tires. Both tire pressures must be equal and within specifications before an adjustment to the cutting edge is made.
Engage the parking brakes and put blocks in the front and the back of the drive wheels. Put wooden blocks under the cutting edge of the blade. The blocks must be small enough to allow measurement of the cutting edge height and large enough to hold the weight of the bowl when it is lifted off the ground. Keep hands and feet out from under the cutting edge or personal injury could occur.
b. Measure and record the distance from each end of the cutting edge to the ground.c. Put the weight of the bowl on the wooden blocks with the machine hydraulics.d. Loosen the setscrews and the nuts that fasten the receivers to the bowl.e. Five turns of the setscrews will change the cutting edge height approximately 12.7 mm (1/2 in).f. Lower the rear wheels to the ground and again measure the distances from each end of the cutting edge to the ground.g. Do adjustment procedures again if necessary.End By:a. install brake assembly (rear) and spindle.
