1. Carefully clean crankcase, oil ducts in particulary check for free passage.2. Check walls and bearing webs for cracks.3. Check condition of bearing bores. If wear marks on bearing shells are not noticeable, check bearing bores with precision gauge. Attention:If there are signs of wear on the bearing shells, the line of bearing housings can be reworked to an oversize outside diameter on a line boring machine. It is not permissible to bore out individual bearing pedestals. Refer to Technical Circulars.Checking The Preload
4-14. Fit crankshaft bearing caps, observing the numbering, into the crankcase. Preload and tighten bolts according to instructions.(Fixture No. 101900)Fig. 4-1
4-25. Set precision gauge to the size indicated in the Technical Data, using a micrometer frame (nominal or oversize).Fig. 4-2
4-36. Measure each main bearing bore at the points 1 and 2 in plane "a", then in the same manner in plane "b" offset by 90 degrees, see also Fig. 4-6, in order to determine any contraction, out-of-roundness or conicity.Fig. 4-37. If the recorded values correspond to those specified in the Technical Data, the respective bearing bore is in acceptable condition and the required preload will be obtained when new bearing shells are installed.
4-48. If the recorded bearing bore diameters differ only slightly from the specified values, repeat the measurements with the new bearing shells installed.Fig. 4-49. Insert new bearing shells, mount bearing cap, then preload and tighten up according to instructions.
4-5
4-610. Gauge each bore at points 1 and 2 in the vertical and horizontal positions "a" and "b".Fig. 4-5 and 4-611. If the recordings show that the bearing tolerances are up to 0.020 mm max. above the values specified in the Technical Data, the crankcase is acceptable for further use. Otherwise, it is necessary for the line of bearing housings to be reworked to an oversize outside diameter on a line boring machine. It is not permissible to bore out individual bearing pedestals. Refer to Technical Circulars. Nor is it permissible to restore the required preload by underlaying the bearing shells or by reworking the parting faces of the bearing bores. a) The main bearing shells are made in two halves and supplied in six dimensions, corresponding to the specified undersizes of the journals. No attempt may be made to recondition the shells.
4-7b) Standard and oversize wall thickness "W" should be taken from the specifications.Fig. 4-7
4-812. Measure width of locating bearing journal of the crankshaft.Fig. 4-8
4-913. Assemble the thrust rings on the locating main bearing and calliper the overall width.Fig. 4-914. Measure end clearance. Compare with the values given in the specifications. If necessary, fit new stop rings.Replacing Bearing Bushing (F2L)
4-1015. Remove the radial seal ring from the back end shield.Fig. 4-10
4-1116. If the main bearing journal has not been re-ground and the bearing bushing shows no signs of damage or wear, gauge the bearing bore at two diagonal points.Fig. 4-1117. Compare measured values with the Specification Data. If necessary, fit new bearing bushing.
4-1218. Draw the bearing bushing in flush, with its oilholes in register with those in the housing.Fig. 4-1219. Fit a new radial sealing ring in the back end shield with the sealing lip facing the bearing bushing and press in so that the back face is flush.Checking Alignment Of Bearings And Crankshaft (As From 3 Cylinders)
20. Coat the main crankshaft journals lightly with inking-in paint.
4-13
4-1421. Place crankshaft in position, Fig. 4-13 and fit bearing caps according to the numbering. Tighten and lock down the bolts according to instructions.Fig. 4-1422. Turn crankshaft slowly several times, without axial displacement and without lifting it.23. Remove crankshaft and check contact pattern of bearing shells. Note for installation:Proper alignment of the bearings can only be obtained if all bearings have uniform contact pattern.24. If signs of alignment errors are noticeable, repeat the test. The line of bearing housings in the crankcase can be reworked to an oversize outside diameter on a line boring machine. It is not permissible to bore out individual bearing pedestals. Refer to Technical Circulars.
4-1525. Check all cylinder seating areas, Fig. 4-15, for defects or damages. The seating areas must be plane and square.
4-1626. In case of damage reface the cylinder seating areas on the crankcase with special tool No. 150020.Fig. 4-16
4-1727. Clean all the tapped holes by running down a top. A greased tap should be used for blind holes.Fig. 4-17
4-1828. Check core hole plug cover for snug fit, replace untight or loose core hole plug covers. Coat new cover with sealing compound, then drive in.Fig. 4-18
4-1929. Check the main bearing bores of the camshaft for damage and visible wear.Fig. 4-19Reworking Cylinder Seating On Crankcase
4-201. Clean the seating area and remove paint residues. Place supporting brackets in position.Fig. 4-20
4-212. Mount refacing device No. 150020 and tighten retaining bolts to such an extent that the refacing device is still movable.Fig. 4-21
4-223. Center refacing device by means of the centering fingers (arrows) and fasten.Fig. 4-22
4-234. Withdraw centering fingers and slide the cutting tool holder out to just above the beginning of the inner diameter of the cylinder seating face to be reworked.Fig. 4-23
4-245. By means of the knurled nut, bring the tool holder down towards the face to be reworked until the cutter just contacts the face.Fig. 4-24 Adjust feed carefully. A full turn (360°) of the knurled nut feeds the tool holder by 1,5 mm.
4-256. Turn back the knurled nut until the cutter is positioned freely above the face to be reworked. Distance "a"Fig. 4-25
4-267. Return tool holder towards the middle of the bore.Fig. 4-268. By means of the knurled nut, set the tool over and slightly beyond the distance "a" (Point 6) to permit satisfactory refacing of the cylinder seating surface. The selected cutting depth should not exceed 0,2 mm. This feed corresponds to a 1/8th turn (45°) of the knurled nut. The smaller the feed, the smaller will be the depth of roughness of the reworked surface.
4-279. After adjusting, secure the device by means of the setscrew.Fig. 4-27
