布切奇SR—113、SR—113N型汽车,发动机是SR—211型,四行程汽化器式顶置汽门V型8缸发动机。曲轴轴向定位的止推轴承圈(以下简称″止推片″)是由两对厚2.5毫米的半圆形高锡铝合金——钢双金属片组成的,装在缸体中间主轴承座的两侧。止推片有合金的一面对曲柄方向,以承受曲轴的轴向压力和调整曲轴的轴向间隙。经修理后的发动机容易产生止推片“磨铁”、脱落、导致曲轴轴向间隙过大、离合器不分离,最后将曲轴、缸体及主轴承座磨成深0.3～0.8毫米的圆形环凹沟,致使发动机达报废程度。我们曾报废过4台发动
Buchery SR-113, SR-113N cars, the engine is SR-211 type, four-stroke carburetor overhead valve V-8 cylinder engine. Crankshaft axial positioning of the thrust bearing ring (hereinafter referred to as “thrust plate”) is composed of two pairs of thick 2.5 mm semi-circular high-tin aluminum alloy - steel bimetal mounted in the middle of the cylinder block main bearing On both sides. The thrust plate has an alloy facing the direction of the crank to withstand the axial pressure of the crankshaft and to adjust the axial clearance of the crankshaft. The engine is easy to repair after the thrust piece “grinding iron”, off, resulting in crankshaft axial clearance is too large, the clutch is not separated, and finally the crankshaft, cylinder block and main bearing mill deep 0.3 ~ 0.8 mm circular ring Ditch, causing the engine up to scrap levels. We have scrapped 4 units
