how full should carraige ( or trolley)gearboxes be filled with oil? also -- i cant see a way to add oil to carraige gearbox beyond 50 percent full... (witout removing motor ,etc..) ...trolley gearbox appears easy access / fill
its going to be 3 plugs on all the gearboxes one will be halfway and the other will be on top of the gearbox where you add it in and actually a plug on the bottom as well for draining. All laserwash 4000s and high velocity's have this. I always bought the oil from a PDQ distributor or washworld you will have to make a homemade bottle or a squirt can with a small tube. When oil starts coming out the halfway plug its full.
