一、齿轮室盖安装 以S195型为例,安装齿轮室盖时,虽然喷油泵凸轮凸起部分朝向曲轴方向,但有的发动机仍出现喷油泵尾端与油泵凸轮相撞,导致齿轮室安装困难。遇此情况,若用螺栓的拧紧力强迫齿轮室盖人位,就可能将齿轮室盖顶裂。正确方法是:双手托住齿轮室盖,先让启动轴伸入齿轮室盖之启动轴孔,向里推进,当油泵尾端与凸轮相撞时,右手拿起扳手扳动泵油螺母60～90度,使油泵柱塞弹簧受力压缩,油泵尾端必然向前移,左手就能顺利地推进齿轮室盖到位。然后放回泵油螺母,对称地拧紧齿轮室盖上的每个螺栓即可。 二、连杆瓦拆装 拆卸:拆下缸盖后,首先清除缸套上部积炭,以利于活塞外出。当拆下连杆螺栓,取出连杆瓦盖及连杆瓦的下半片,再推出活塞连杆组时,连杆瓦的上半片很容易掉进油底壳,而取出瓦片非常困难。防止瓦片掉进油底壳的拆法
First, the gear chamber cover installation S195-type, for example, the installation of the gear chamber cover, although the convex part of the fuel pump cam toward the crankshaft direction, but some engines still appear fuel injection pump end collision with the pump cam, resulting in gear room installation difficulties . In this case, if the fastening force of the bolt is used to force the gear cover, it is possible to crack the gear cover. The correct way is: hands hold the gear chamber cover, let the start shaft into the gear shaft cover shaft start to promote, when the rear end of the pump and the cam collision, the right hand to pick up the wrench to move the pump oil nut 60 ~ 90 degrees, the pump plunger spring force compression, the end of the pump must move forward, the left hand will be able to successfully promote the gear room cover in place. Then replace the pump oil nut and tighten each bolt on the gear chamber cover symmetrically. Second, the connecting rod disassembly Disassembly: Remove the cylinder head, first remove the upper cylinder coke, in order to facilitate the piston out. When the connecting rod bolt is removed, the lower half of the connecting rod cover and the connecting rod cover is removed, and then the piston connecting rod set is released, the upper half of the connecting rod shoe can easily fall into the oil pan, and removing the tile is very difficult. To prevent the tile fell into the sump demolition method
