机型，分为板式和铜管式两种。机油冷却器使用一段时间后，会结有水垢或其它杂物，影响冷
却效果和机油压力，尤其是使用的冷却水水质较差时更应注意。清洗机油冷却器的方法是
:
先把
进出水管及进出油管拆除，将冷却器从机体上卸下，板式的则拆开冷却器的盖板，将芯板子取
下，用柴油对芯板内腔进行冲洗，将内腔的油垢冲洗掉，然后清除芯板表面及水腔内的水垢，
以提高冷却效果。清除圬垢后，用干净的柴油冲洗，并擦拭干净。铜管式的则拆开两端端盖，
用钢丝扎紧干净的棉纱或布条，沾干净的柴油逐条铜管进行通洗，将管内的水垢清除干净，通
洗完后再用干净的柴油冲洗一次，端盖及壳体也要清洗干净。清洗后的机油冷却器组装时应注
意密封垫片应予以更换，组装时螺栓应按对角顺序均匀拧紧，以保证不出现渗漏现象。
Check the oil level in the oil pan regularly and the oil level shall be between the upper
and lower scale of the oil dipstick (Fig 2-25). There is oil drain plug at the bottom of the oil pan
to drain oil. The oil cooler is of water cooling type; there are 2 types: plate and copper pipe
depending on different models. After a period of using, the furring or other impurities will
affect the cooling effect and oil pressure. This will happen when using cooling water with poor
quality. The cleaning method for the oil cooler is that: remove the water inlet/outlet pipe and
fuel inlet/outlet pipe, then remove the cooler from the engine. Open the cover to remove the
element if the cooler is of plate type, then wash the element plate with diesel oil to clean the
oil dirt, then remove the furring on the element plate and in the tank to improve the cooling
effect. After that, wash it with clean diesel oil and wipe it clean. If the cooler is of copper pipe
type, remove the end cove on both sides, use steel wire to strap the clean yarn and cotton,
dip it into clean diesel oil to clean each copper pipe. Replace the gasket when assembling the
cooler after cleaning; tighten the bolts according to the cross order when assembling to
ensure no leaking.
机油滤清器为纸质滤芯，根据不同的用户分为两种型号，一种为旋装式，型号为 JS0818
，此型号滤清器更换滤芯时须和外壳一起更换。另一种滤清器型号为
J1012
，其滤芯清洗干净
后可重复使用。当机器使用工作时间累计
250
小时时应更换滤芯（
JS0818
型）或清洗滤芯，
清洁的柴油或汽油清洗后再用压缩空气吹干（
J1012
型）。安装滤清器时，先用清洁的机油加
