Tools / consumables needed
- Metric socket set (10–32 mm range), deep sockets for large bolts
- Combination wrenches (metric)
- Breaker bar and extensions
- Torque wrench (range to at least 200 Nm)
- Hydraulic jack or floor jack (sized for tractor) and heavy-duty jack stands or axle stands / transmission jack
- Pry bar and dead-blow hammer
- Penetrating oil (e.g., PB Blaster)
- Punch or drift and cold chisel for stuck pins
- Wire brush / rag and solvent for cleaning
- New mounting bolts/nuts, washers, cotter pins / locking hardware (do not reuse)
- Replacement shock absorber(s) - OEM or direct-fit aftermarket specified for Massey Ferguson MF6400
- Replacement rubber bushings / sleeves if worn
- Threadlocker (medium strength) or new nylock nuts as appropriate
- Safety gear: eye protection, gloves, steel-toe boots
Safety precautions (must follow)
- Park on level ground, chock wheels front and rear, engage parking brake, shut off engine and remove key.
- Support tractor with appropriate rated stands — never rely solely on a hydraulic jack.
- Lower any raised implements and make sure PTO disconnected and immobilized.
- Support the axle or component that the shock attaches to before removing mounting hardware to prevent sudden movement.
- Use two people for heavy components or awkward positions.
Step-by-step replacement (general MF6400 procedure)
1. Identify shocks and mounting points
- Locate front and/or rear shocks (two per axle or single pair depending on model/suspension). Note upper and lower mounting styles (bolt-through eye, pin with linchpin, or bracket & nut).
2. Prepare and apply penetrating oil
- Spray bolts/pins, let sit 10–15 minutes. Clean dirt/debris from mounts with wire brush.
3. Support the tractor/suspension
- Use a jack to lift the axle or chassis slightly just enough to take load off the shock. Place jack stands under stable points (axle housing, subframe). The goal: shock should be unloaded (not necessarily fully extended) so bolt can be removed easily.
4. Remove lower mount first (recommended)
- Hold the upper mount with a wrench while loosening lower nut with socket/breaker bar.
- If pin-type mount has a retaining clip/cotter pin, remove it first. Use punch/drift to drive out stuck pins. Use two people if needed to prevent the shock from dropping.
5. Remove the upper mount
- Once lower is free, support the shock and remove upper nut/bolt or pull out the locating pin. Watch for shock to come off suddenly; control it.
6. Inspect mounts and bushings
- Remove old rubber bushings/sleeves. Clean and inspect mount brackets for elongation, cracks or corrosion. Replace worn bushings; if sleeves are collapsed, press in new ones.
7. Prepare new shock
- Confirm replacement shock is correct length and mounting pattern. Compare with old shock. Install new bushings/sleeves if required. Rotate orientation to match original (some shocks are directional — gas-charged rod orientation usually points up).
8. Install upper mount first
- Position shock in bracket, insert bolt/pin, fit new nut/washer/cotter pin. Lightly snug but do not fully torque until weight is on suspension if manufacturer requires a specific sag position (check manual). If no special instruction, torque to spec.
9. Install lower mount
- Align lower eye/clevis and fit bolt. Use new locking hardware. Tighten to spec.
10. Torque to spec
- Torque all mounting bolts to the Massey Ferguson MF6400 service manual specification. If manual not available, use a torque wrench and tighten securely; avoid over-torquing and deforming bushings. (Do not rely on guesswork for critical fasteners — obtain the manual for exact Nm values.)
11. Lower tractor and test
- Remove stands and lower tractor slowly. Cycle suspension by driving short distance and re-check torque after first few hours of operation.
How the tools are used (quick guide)
- Breaker bar: initial high-torque break on seized nuts/bolts. Use controlled force.
- Torque wrench: final tightening to specified Nm; set and apply smooth steady pull until it clicks.
- Jack & stands: jack raises the weight; stands hold it safely. Always place stands on rated contact points and test stability.
- Penetrating oil + punch: frees corroded pins — soak, then tap out with punch.
- Pry bar / dead-blow hammer: align holes and persuade stubborn bushings or sleeves into place without damaging components.
Replacement parts required
- Correct MF6400 shock absorber(s) (order with chassis serial/model to ensure correct length/mounts)
- New mounting bolts/nuts/washers and cotter pins or locking nuts
- New rubber bushings/sleeves if old ones show wear
- Optional: anti-seize on bolt shanks, threadlocker on nuts if recommended
Common pitfalls / mistakes to avoid
- Relying solely on a jack — risk of sudden collapse. Always use stands.
- Removing both mounts without supporting the axle — axle or component can drop and damage lines/other parts.
- Reusing old bolts, nuts, or collapsed bushings — leads to premature failure and noise.
- Incorrect shock orientation or wrong-length shock — results in binding or limited travel.
- Not torquing to spec — under-torque can allow movement and wear; over-torque can crush bushings.
- Not checking clearance for hydraulic lines or wiring — ensure nothing is pinched during installation.
- Ignoring surrounding wear — replace worn mounts or brackets to avoid new shock failure.
Final checks
- Confirm all hardware tight and safety clips installed.
- Verify no interference with hoses, wiring or brake lines.
- Road-test at low speed, listen for clunks, re-check torque after initial operation.
