The Metso Nordberg C80 Jaw Crusher Toggle Plate Lug (Part No. ONA-922321) is a dedicated connecting and locating block used on the toggle plate side of the C80 jaw crusher. It works as the support/ear/lug for the toggle plate: it gives the toggle plate an accurate mounting position, keeps the working angle correct, and transfers the crushing force from the toggle plate back to the crusher frame or moving jaw.
Because the toggle plate is a key overload and force-transmitting part in a jaw crusher, the lug that holds it must be dimensionally correct and wear-resistant. This part is therefore supplied as a wear & spare part and is designed to be replaced during regular maintenance.
Fits machine: Metso / Nordberg C80 Jaw Crusher
Function area: toggle plate (toggle) side, between the toggle and the frame/moving jaw
Typical use cases:
Periodic overhaul or mid-life service of a C80
Replacement of a worn, ovalized or cracked original toggle plate lug
When installing a new toggle plate, toggle seat or jaw plates, and correct alignment is required
Aggregate, quarry, mining, cement and metallurgy crushing lines using C80 as primary crusher
In short: if you run a Metso / Nordberg C80 and your toggle plate mounts through a lug/ear, this is the small part that locates and holds it.
Exact C80 Compatibility
Manufactured to suit Metso / Nordberg C80 dimensions and hole spacing, with ref. code ONA-922321, so it can be installed directly without re-drilling or welding.
High-Strength Steel Construction
Made from high-strength cast or forged steel to withstand the alternating compression and tension loads coming from the toggle plate during crushing.
Accurate Positioning of the Toggle Plate
The machined faces and multiple holes provide a stable seat for the toggle plate, helping to maintain the correct toggle angle and crusher stroke.
Force Transfer and Protection
Ensures that the force from the toggle plate is correctly transferred to the crusher frame/moving jaw, helping protect bigger and more expensive components.
Anti-Corrosion Surface Treatment
Supplied with painted / anti-rust surface so it can be stored, shipped or kept as inventory spare without fast corrosion.
Easy Replacement During Maintenance
Small, independent part → can be changed quickly during shutdown, reducing downtime and keeping the crusher available.
Can Be Shipped Together with Other C80 Wear Parts
Frequently ordered together with toggle plate, toggle seat, cheek plates and jaw plates to reduce freight and purchasing cycles.
Q1: What does this toggle plate lug actually do?
It works as the mounting and supporting ear for the toggle plate. Without it, the toggle plate cannot be positioned or fixed correctly, and the crusher may lose its designed stroke and protection function.
Q2: Can I use this part on other Metso jaw crushers (C96, C100, C110…)?
No. This lug is made specifically for the Nordberg C80. Other models have different shapes, thicknesses and hole patterns. Always match the lug to the exact crusher model.
Q3: When should I replace the toggle plate lug?
Replace it when you see:
elongated / oval holes
worn or hammered support faces
visible cracks or deformation
frequent or abnormal toggle plate failures
A worn lug lets the toggle move, which increases noise and impact, and can lead to premature toggle or frame damage.
Q4: Is this part supplied together with the toggle plate?
Normally it is supplied as a separate spare. Many customers replace the toggle plate and the lug at the same time to restore the original alignment.
Q5: What material is it made from? Can it be made harder?
Standard supply is high-strength cast/forged steel suitable for impact and cyclic loads in jaw crushers. For very abrasive or heavy-duty applications, it can be produced to drawing or with upgraded material on request.
Q6: Why is it painted yellow/gold in the photo?
That is a protective / identification coating for storage, shipping and warehouse management. It does not affect the fitment to the C80 crusher.
