This suspension shock absorber is specifically engineered for full compatibility with the following tractor series:

• MTZ-1025 Series
• MTZ-920 Series

• Routine Inspection: Check every 400 operating hours (or after 15-20 heavy farming cycles). Inspect for rubber element cracks, steel housing rust, and loose mounting bolts.
• Cleaning: Wipe the housing with a dry cloth monthly to remove mud, dust, or residues. Avoid harsh solvents that can damage rubber components.
• Replacement Cycle: Recommended replacement every 1,800-2,500 operating hours, or sooner if vibration attenuation decreases significantly.

• Environment: Store in a dry, well-ventilated area with relative humidity ≤65% to prevent steel corrosion.
• Temperature: Maintain storage temperatures between -5°C and 35°C; keep away from direct sunlight or heat sources to prevent rubber aging.
• Packaging: Keep parts in original sealed packaging; avoid contact with oil, fuel, or fertilizers.
• Handling: Store vertically to prevent housing deformation and do not stack heavy objects on top.

• Pre-Installation: Confirm the part matches 70-4216040 and verify your tractor model (MTZ-1025/920).
• Tools Required: Torque wrench (28-32 N·m), socket set, and wire brush.
• Step 1: Lift the tractor safely using jack stands to access the suspension system.
• Step 2: Remove the old shock absorber by unscrewing the mounting bolts.
• Step 3: Clean the mounting brackets with a wire brush to remove rust and debris.
• Step 4: Install the new shock absorber and tighten bolts to 28-32 N·m (do not over-tighten).
• Step 5: Lower the tractor and perform a test ride to ensure stability.
