Baoji Oil Machinery NJ15 original is the model customer refers….. 1. Customer concern start with the overall finish of the product.In the rejected pieces, even the weld spatters were not removed, painting and surface finish was not industrial grade.We had sent some photos earlier….Iet me try to dig that out.2. Gear Train should be silent with cup and cone gears as in the original NJ15. This was the main complaint…..as the equipmentswere put in service, the unit had started making sound and vibrating.3. In terms of marking too, please refer the original NJ15. Hazardous area rating related markings should be on all electrical components as applicable, directions / torque levels / electrical connections marked as applicable, Model number and standard nameplates…. Daisy, I too know that these are just mud agitators and super finishing is not required. However, when the minimum decent look is not given, a “sub-standard material” kind of feeling it develops. That is what creates all the problems I believe. Please have your operations team comparing your MT-NJ15 with original BOM NJ 15…. Please put this on high priority, we need the 41 units order booked by next week…..
