How to identify a jaw plate drawing number
Use the crusher nameplate, parts book and worn part to confirm the jaw position, drawing number and revision.
Identify the machine and jaw position
Photograph the full nameplate and record the manufacturer, model and serial number. Specify the fixed or moving jaw. Include photos of both sides of the worn plate and its mounting position. One machine model can take different tooth profiles or mounting arrangements.
Check the parts book
Use the machine serial number to locate the relevant parts book. Record the part number, drawing number and revision. Photograph cast-in or stamped markings separately so an engineer can identify the part reference, heat or casting mark.
Supply dimensions when the drawing is unavailable
Measure overall length and width, thickness at the mounting area, locating slots or hole positions and tooth pitch. Include a side photo of the tooth profile and mark where the part is worn and where you took each measurement.
