Folksvagen Sharan/Sharan repair>> The diesel engine>> Cranked shaft and radical bearings>> Definition of an axial backlash of a cranked shaft

Fig. 440. Bearings of a cranked shaft: 1 — loose leaves of bearings № 1, 2, 4 and 5. Loose leaves with flutes for greasing are located in the block of cylinders, in covers of bearings loose leaves without lubricant flutes are located; 2 — bolts of covers, 65 Нм + 90 Нм; 3 — covers of radical bearings, the cover №1 is located from outside pulleys, the cover № 3 has dredging for adjusting washers; 4 — bearing loose leaves № 3. The loose leaf with a flute for greasing is located in the block of cylinders, in a bearing cover the loose leaf without lubricant flutes is located; 5 — adjusting washers for the bearing № 3; 6 — a cranked shaft; 7 — adjusting washers of the bearing № 3, located in the block of cylinders





Before removing a cranked shaft that it is possible to make only on the dismantled engine, measure an axial backlash that the nobility at assemblage, whether it is necessary to change adjusting washers on the average radical bearing (fig. 440).

Fig. 441. Measurement of an axial backlash of a cranked shaft with the help щупа





Insert щуп on the average bearing (number 3) between a cheek of a cranked shaft and the inserted adjusting washer as it is shown on fig. 441 and check up size of an axial backlash which should settle down in limits from 0,07 to 0,17 mm. The greatest backlash should not surpass 0,37 mm.
Pay attention to, that the axial backlash has been chosen completely, for what rest the lever (is better the wooden handle of any tool to avoid damage) in a cheek of a cranked shaft and with its help wring out a shaft aside. Inserting various on a thickness щупы, establish exact size of a backlash.
It is possible to measure an axial backlash by means of the indicator which should be attached to the face party of the block of cylinders, and to establish a measuring finger on an end face of a cranked shaft. After that press a cranked shaft in an indicator direction. Establish the indicator on a zero and press a shaft in an opposite side. Look backlash size on the indicator.
