165F汽油机连杆系LD1铝合金锻成,连杆材料内含有轴瓦的合金成份,可以直接与轴配合使用,因此该连杆不需另行配用瓦片。我们在废旧零部件回收工作中,发现有大量165F汽油机连杆总成,在使用中由于连杆大端孔缺油烧坏而报废。为了降低农机修理费用,减轻贫下中农负担,对于这些连杆总成,我们采用镗扩连杆大端孔, 165F Gasoline engine connecting rod series LD1 aluminum alloy forging, connecting rod material contains the bearing alloy components can be used directly with the shaft, so the rod without additional use of the tile. In the recycling of used components, we found that a large number of 165F gasoline engine connecting rod assemblies were scrapped in use because of the lack of oil in the large connecting rod bore. In order to reduce the cost of agricultural machinery repair and reduce the burden on the poor middle peasants, for these connecting rod assembly, we use the large hole bore extension rod,
