Materials and Processes
Review the following toggle seat material and process information when assessing specifications and alternatives.
Alloy steel forgings
Specify toggle seat material and manufacturing method from the part drawing. The material must meet support-load, contact-wear and toughness requirements; a generic alloy steel grade is not an OEM standard for every model.
Surface treatment
Verify contact-face heat treatment, hardness and core properties against the part drawing. Do not add a surface-hardening process without design approval.
Fit and contact accuracy
Verify toggle plate and seat contact profiles, mating dimensions and assembly condition against the model-specific drawing.
Wear and Replacement Criteria
Use the following toggle seat wear patterns and replacement considerations during maintenance.
Main wear zones
Wear on the toggle contact faces and locating-groove sides. Seat wear affects toggle plate life and discharge-setting stability.
Replacement Criteria
Check contact-face wear, grooves, plastic deformation and profile deviations against model-specific maintenance limits.
Recommended Actions
Inspect contact-face wear regularly and check the seats whenever the toggle plate is replaced. Follow the model-specific maintenance manual for lubricated or lubrication-free operation.
Information Needed for an Inquiry
Equipment model, such as C140; part number; front or rear seat position; and quantity. Front and rear seats have different dimensions.
