Description

Left-hand disc leaf spring 90x13 mm - Part number 57671

Replacement left-hand (LH) torsion leaf spring for disc harrows, cultivators, and flexible tillage units, commercial part number 57671. Engineered to maintain consistent down-pressure on the disc blade while absorbing shock loads, severe ground vibrations, and stone impacts. Manufactured from high-grade heat-treated spring steel, it provides outstanding fatigue resistance and retains its elastomeric memory and load rate through demanding field operations in tough soils. Features a heavy-duty 90x13 mm flat bar profile and a 28 mm mounting hole for secure bolting onto the frame brackets on the left-hand side of the implement.

Key features

High-tensile spring steelHeat-treated alloy steel formulation engineered to deliver high resilience, constant elasticity, and resistance to fatigue cracking.

Left-Hand (LH) specific geometryFormed and angled specifically for fitment onto the left-hand side disc gang elements.

90x13 mm flat profileHeavy-duty cross-section designed to provide optimal disc penetration force without permanent deformation.

Precision 28 mm mounting holeAccurately sized center bore for 28 mm mounting pins or heavy-duty bolts, eliminating slack and play.

Implement frame protectionDampens harsh shock loads and vibration feedback to safeguard the machine's primary frame structure.

Fitting tipsPrior to installing the new spring onto the left-hand side of the machine, thoroughly clean the frame mounting bracket and pin seat, removing dirt, rust scale, and debris. Inspect the 28 mm pivot pin or mounting bolt for excessive wear or grooving that could cause stress concentrations on the spring eye. Position the spring ensuring the correct left-hand orientation and slide the 28 mm fastener through the hole. Torque all hardware to the machinery manufacturer's required specification, verifying that the spring has clear travel allowance throughout its full flex range. Re-torque the mounting hardware after the initial 5 to 10 working hours in the field.
