一、利用开口扳手巧拆零件 1.巧拆495A型柴油机的活塞连杆 在不分解495A型柴油机的情况下,要拆出活塞。连杆等零件时,一般是在油底壳拆检窗口用扁长木棒往上顶的方法来拆取。这种方法费工、费时。现介绍利用开口扳手巧拆的方法: (1)拆去柴油机缸盖、连杆瓦盖等,用三角刮刀仔细刮去缸套上部的积炭。 (2)把需要拉出的活塞、连杆转到活塞上止点后少许。 (3)选择17-19mm或19-22mm的开口扳手一把,取直径为φ1.5～2毫米的铁丝若干弯成长环状,套在开口扳手(19mm)一端的开口内。 (4)以活塞涡流坑缺口处把开口扳手
First, the use of open-end wrenches cleverly disassemble parts 1. Clearance demolition 495A diesel piston rod without breaking the 495A-type diesel engine, to remove the piston. Connecting rod and other parts, the general is in the oil pan inspection window with a long stick upstairs to dismantle. This method takes time and effort. Now introduce the use of open wrench clever disassembly method: (1) Remove the diesel cylinder head, connecting rod cover, etc., with a triangular scraper scrape the top of the cylinder liner coke. (2) Need to pull out the piston, connecting rod to the piston after a little bit of top dead center. (3) Select a 17-19mm or 19-22mm open-end wrench, take a diameter of φ1.5 ~ 2mm iron wire several turns into a ring, set in the open end of the wrench (19mm) end of the opening. (4) Piston whirlpool pit openings open the wrench
