The thrust washers (32a and 32b) inserted in cylinder crankcase and in bearing cap on both sides are similar in design.<\/div>\n
As a protection against distorsion and to avoid assembly faults, the thrust washers in bearing cap are provided with two holding lugs each, with the lower lug placed out of center. In addition, all thrust washers are chamfered at one end.<\/div>\n<\/div>\n<\/td>\n

Main oil ducts in crankcase open (also refer to 01-130). Oil spray nozzles removed (18\u2014040). Oil ducts in cylinder crankcase and in crankshaft carefully cleaned.   Check crankshaft for cracks, dimensional stability and concentricity (03-318). For durability, the 3rd crankshaft bearing (fitted bearing) has been provided with standard bearing shells and thrust washers.   The thrust washers absorb the axial forces of the crankshaft. The thrust washers (32a and 32b) inserted in cylinder crankcase and in bearing cap on both sides are similar in design. As a protection against distorsion and to avoid assembly faults, the thrust washers in bearing cap are provided with two holding lugs each, with the lower lug placed out of center. In addition, all thrust washers are chamfered at one end. 32 Bearing shells 32a Thrust washers in cylinder crankcase 32b Thrust washers in bearing cap 36\u00a0 \u00a0 Cylindrical pin 10m 6 x 16 37\u00a0 \u00a0 Cylindrical pin 8m 6×16 39\u00a0 \u00a0 Bearing cap 41\u00a0 \u00a0 Bolts M 12 x 75 03.8-320\/3 F 2       When reconditioning crankshafts, regrind width of fitted bearing journals to one of the dimensions named in table (section „Data”).

On these engines, do not install connecting rod bearing shells of engine 617.912.   To improve bearing shell seat in cylinder crankcase on engine 617.950, the standout of the bearing shells has been increased from 0.000\u20140.030 mm to 0.030-0.060 mm.
