Reply to "GEAR FAILURE AT SCREW PUMP"

Thanks Dave for material. 

 the lubrication is just follow the manufacturer and no any abnormal. The spec for oil is VG100, The oil was maintaining and changing as manufacturer then i have no doubt in oil issue. 

 As see the defect mark, look like a very excessive load effect on gear and broken the teeth surface, the spectrum also shows high GMF relate to gear wear , also indicates very high load. 

then the next question is why the high load on the gear , i keep going my investigation on this way/...

 Thanks 

RM
