裝載機變矩器呼吸器主要是平衡裝載機變矩器齒輪室內壓力，正常情況下，齒輪空內只有少量的潤滑油液(減壓閥溢流的油液)，如內部的油液增多或存在氣壓，則會擊濺油液到呼吸器通氣孔上并溢出。這種故障一般先檢查變矩器內是否有氣壓增高，即檢查制動系統的壓縮空氣是否進入了行走系。
Shandong loader torque converter respirator mainly balanced converter gear loader chamber pressure, under normal circumstances, only a small amount of lubricating fluid (oil overflow valve), such as increased or presence of oil inside the gear blank pressure will splash and spill oil into the vent on the respirator. Such failures are generally first check whether there is increased pressure within the torque converter, which compressed air braking system checks whether walking into the system.

裝載機由于氣路與行走油路唯一溝通的地方就是變速分配閥，因此檢查變速分配閥隔離桿上的“0“型圈足否損壞，方法是啟動發動機，氣壓在o. 8-1.OMPa后熄火，傾聽變速閥部位是否有漏氣聲，進而可打開變速箱加油口蓋，檢查是否有氣體連續排出，如有則可判定“o"型圈損壞。如以上正常，則由于山東裝載機齒輪室油液增多，一般是變矩器回油散熱回路堵塞，重點檢查異輪座回油路、機械油回油濾清器、機械油散熱器以及其他回油管路是否堵塞。
Shandong loaders due to gas path and walking the oil is the only place where the communication speed distribution valve, so check valve isolation allocation shift lever to "0" type Quanzu No damage is to start the engine, the air pressure in the o. 8-1. OMPa after flameout, whether listening to shift parts of a valve leak sound, and then open the gearbox oil filler cap and check whether there is a continuous discharge of gas, if you can determine the "o" ring damage. As described above normal, due to the increase of oil Shandong loader gear chamber, usually back to the oil cooling loop converter plug, focus on checking different wheel seat back to asphalt, machine oil back to the oil filter, oil cooler, and other machinery back drain line is clogged.
