Repair Sharan/Sharan Volkswagen>> Diesel engine>> Cranked shaft and radical bearings>> Definition of an axial gap of a cranked shaft

Fig. 440. Bearings of a cranked shaft: 1 — loose leaves of bearings No. 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 N · m + 90 N · m; 3 — covers of radical bearings, the cover No. 1 is located from pulleys, the cover No. 3 has dredging for adjusting washers; 4 — bearing No. 3 loose leaves. The loose leaf with a flute for greasing is located in the block of cylinders, in a cover of the bearing the loose leaf without lubricant flutes is located; 5 — adjusting washers for the bearing No. 3; 6 — a cranked shaft; 7 — the adjusting washers of the bearing No. 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 gap that the nobility at assembly, whether it is necessary to change adjusting washers on the average radical bearing (fig. 440) .

Fig. 441. Measurement of an axial gap 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 size of an axial gap which should settle down in limits from 0,07 to 0,17 mm. The greatest gap should not surpass 0,37 mm.
Pay attention to, that the axial gap was chosen completely, for what rest the lever (best of all 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 thickness щупы, establish exact size of a gap.
It is possible to measure an axial gap 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 the indicator direction. Establish the indicator on a zero and press a shaft to the opposite side. Look at gap size on the indicator.
