How to check garbage truck crankshaft clearance Install garbage truck thrust washers and crankshaft main bearing caps and position the crankshaft in the cylinder to measure the thrust clearance. The gap between the thrust bearing and the crank arm is measured when the crankshaft moves to the head forward or backward with the scale indicator. If the measured value exceeds the limit, replace the thrust bearing and remeasure. If you still exceed the limit, L crankshaft is required. First, visually inspect the surface of the crankshaft main journal and the connecting rod journal surface for smoothness, scratches, and scratches. Finally, the roundness error and cylindricity error of each crankshaft crankshaft are calculated. The calculation method is similar to the method of measuring cylinders. If any of the journals in the trash can journal is severely damaged or the amount of uneven wear exceeds the limit, regrind the crankshaft or replace it with a new one. The main bearing reservoir clearance calculation method, the main bearing is mounted on the cylinder block and the main bearing cap, and the main bearing arm tightens the main bearing cap bolt to the specified torque. Use the inner diameter gauge to measure the inner diameter of the main bearing. Bearing clearance = main bearing inner diameter - crankshaft main journal diameter. If the calculated value exceeds the limit, select the appropriate main bearing according to the main bearing inner diameter and the crankshaft journal diameter to obtain the specified bearing reservoir clearance. Measured using a plastic feeler gauge, thoroughly removes oil and dirt from the main shaft of the garbage truck crankshaft and each bearing surface. Gently cut the plastic feeler gauge shorter than the bearing width and place it in the axial direction of the crankshaft, avoiding the oil hole. Install the main bearing on the cylinder and the main bearing cap, and screw the main bearing cap bolt to the specified torque. Do not rotate the crankshaft at this time, remove the main bearing cap and bearing, and use the scale on the scale to measure the widest point of the plastic feeler. This width is the bearing reservoir clearance. XCMG Chu Sheng (Hubei) Special Purpose Vehicle Manufacturing Co., Ltd.
