Models and Key Dimensions
Metso Superior 42-65/50-65/54-75/62-75/60-89/60-110/70-89
Drawing Number / Part Number
Provide the equipment nameplate, complete model and existing part number so that the installation position and drawings can be checked.
Drawing Revision
Confirm dimensions by measuring the sample or using the customer drawing. Cross-check the drawing revision against the model on the equipment nameplate.
Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
Alloy Steel 42CrMo4
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Forged 34CrNiMo6 steel; confirm the heat treatment, tooth surface hardness and core properties against the original drawing and technical agreement.
Select materials to suit OEM specifications and operating conditions; confirm the final grade and heat treatment against the drawing.
Wear and Replacement Criteria
Common wear patterns and maintenance guidance are outlined below. Determine replacement intervals from operating conditions, processed material and equipment performance data.
Common Wear Patterns
- Contact fatigue pitting of tooth flanks
- Tooth scuffing: inadequate lubrication under heavy loads causes localized welding and tearing of metal
- Tooth root bending fatigue cracks
- Tooth abrasion caused by contaminated lubricant
Replacement Criteria
Assess replacement against the pitting and tooth thickness limits in the gear drawings and maintenance specification. Replace immediately if tooth root cracks occur.
Materials and Processes
Materials, heat treatment, composite construction and inspection requirements depend on the specific drawing, operating conditions and technical review.
Material Grade / Substrate
Forged alloy steel 42CrMo4 / 34CrNiMo6; confirm the heat treatment, tooth surface hardness and core properties against the original drawing and technical agreement.
Heat Treatment Condition
Follow the applicable standard for the material grade; confirm heat treatment and hardness requirements against the drawing
Composite / Hardfacing Requirements
Follow OEM design requirements; confirm any hardfacing or composite construction against the drawing
Dimensions and Inspection
Inspect key dimensions against the drawing for the OEM part number. Check mounting and sealing surfaces individually and perform UT/MT non-destructive testing on castings.
Parts with the same name may not be interchangeable because of differences in machine model, drawing revision, mounting interface or material specification. Use the complete model, serial number, drawing number and drawing before manufacture.
