Properly maintaining and cleaning your M62 crash gear comes down to three core habits: removing packed mud and debris after every use, inspecting chains and hooks for wear or cracks, and applying light oil to all moving metal surfaces before storage. Following these steps prevents corrosion, keeps traction material effective, and extends the service life of your gear significantly.
This guide is written for beginners and general enthusiasts who own or operate M62 crash gear and want clear, actionable instructions without unnecessary jargon.
Understanding What M62 Crash Gear Is
The M62 crash gear refers to the towing and traction assembly used on the M62 military cargo truck and similar platforms. It typically includes heavy-duty tow chains, shackles, hooks, binder straps, and sometimes sand chains or traction mats designed for off-road recovery. The entire kit lives on the front or rear frame rails and takes a beating from dirt, moisture, road salt, and vibration.
When these components get clogged with mud or left wet, they corrode quickly. A single seized shackle pin or rusted hook can make emergency towing impossible when you actually need it. That is why routine care matters more than most operators realize.
Essential Tools and Supplies You Will Need
You do not need a specialized shop to maintain this gear. A few basic items are enough to keep everything in reliable shape:
- Bright wire brush or stiff nylon brush for chain and hook scrubbing
- Low-pressure water source such as a garden hose with a spray nozzle
- Mild detergent or automotive parts cleaner
- Clean rags or shop towels
- Light machine oil or WD-40 brand silicone spray for metal protection
- White lithium grease for shackle pins and binding hardware
- Flashlight for close visual inspection in shadowed areas
Keep these supplies together in a small tub or bag attached to your vehicle or storage rack so you can grab them immediately after field use.
Step-by-Step Cleaning Procedure
Follow this sequence every time the gear sees heavy off-road use or sits exposed to rain, mud, or road treatment chemicals.
- Remove the crash gear from the truck if possible. Lay it flat on a clean concrete surface or work bench where debris can fall away rather than redeposit onto the chains.
- Sweep or brush loose dry dirt away first. Use the wire brush along the length of each chain link and around hook jaws. Do not skip the内侧 of bent hooks where grime hides.
- Rinse with low-pressure water while continuing to agitate stubborn deposits with the brush. Avoid high-pressure washers because they force water into shackle threads and pin seams where trapped moisture later causes hidden corrosion.
- Apply a small amount of mild detergent to particularly greasy or oily sections. Scrub gently, then rinse thoroughly until no soap residue remains.
- Dry every component completely with clean shop towels. Pay special attention to the contact points between adjacent chain links and the threading inside shackles.
- Allow the assembled gear to air-dry in a well-ventilated area for at least one hour before reinstallation or storage. Overnight drying is ideal in humid climates.
Inspection Checklist Before Reassembly
Cleaning reveals problems that washing alone cannot hide. While the metal is still dry and clean, run through this short inspection list:
| Component | What to Check | Acceptable Condition |
|---|---|---|
| Tow chains | Stretch, nicking, cracked welds | No elongation over 5 percent, smooth links |
| Hooks and bow Shackles | Bend, throat opening, cracking near swivel | Closure springs intact, pins thread smoothly |
| Binder straps and turnbuckles | Frayed webbing, stripped threads | Webbing free of cuts, threads engage fully |
Mark any damaged piece with bright tape and replace it before returning the kit to service. Never weld a cracked hook or stretch a deformed link back into shape.
Lubrication and Corrosion Prevention
Once everything is clean and dry, protect the bare metal surfaces before putting the gear back on the truck. Apply a thin coat of light machine oil to all chain links, hook bodies, and shackle pins. Work the oil into the link joints by flexing each segment by hand so the protective film reaches the interior metal.
For shackle pins and turnbuckle threads, use white lithium grease instead of liquid oil. Grease stays in place longer and resists being flung off during transport. Coat the threads evenly, then screw the pin through to distribute it.
If you store the gear indoors or under a covered rack, a light oil coating is sufficient. If it remains mounted on an exterior truck frame, consider a dedicated rust preventative spray formulated for outdoor steel equipment. These sprays leave a waxy barrier that tolerates vibration and temperature shifts better than plain oil.
Storage Best Practices for Long-Term Reliability
The way you hang or coil your crash gear determines how fast it deteriorates between uses. Here are the practical standards most experienced operators follow.
Never stack wet or damp chains directly on top of each other. Trapped moisture between coils creates rapid surface rust within hours. Always allow full airflow around every link during the drying phase.
Coil chains loosely rather than folding them tightly. Tight bends stress link plates over time and accelerate fatigue at the bend radius. A gentle figure-eight or large loop coil keeps metal stresses even.
Hang hooks with the latch facing upward when possible. This prevents lint and dust from lodging inside the closing mechanism, which can stop the spring latch from seating properly during an emergency load application.
Store the complete kit in a labeled canvas bag or mounted rack away from standing water sources. If the gear must stay mounted on the truck in a damp environment, cover it with a breathable vinyl tarp instead of plastic sheeting, which traps condensation against the metal.
Common Mistakes That Damage Crash Gear Early
Avoid these frequent errors to keep your M62 crash gear performing reliably year after year:
- Skipping post-use cleaning after mud or salt exposure. Salt accelerates pitting corrosion far faster than ordinary dirt ever could.
- Using harsh acidic cleaners on galvanised or coated hardware. These strips away protective finishes and exposes fresh steel to immediate oxidation.
- Oiling only the outside of chains while ignoring pins and internal link gaps. Corrosion always starts where you cannot see.
- Tightening turnbuckle ends past their safe travel limit. Stripped threads on a turnbuckle mean you lose tension control exactly when you need it most.
- Leaving binder strap buckles dirty and grit-packed. Grit acts as an abrasive that wears buckle prongs and weakens the anchor point over repeated cycles.
Building a Simple Maintenance Schedule
You do not need a complicated logbook. A consistent rhythm works best for most operators.
Clean and inspect after every off-road deployment, winter road-salt season, or prolonged wet storage period. Lubricate at the same time unless you recently applied fresh coating.
Perform a full functional test once per month during active use seasons. Pull each shackle pin in and out, open and close every hook latch, tension a binder strap through its complete range, and visually walk through the inspection checklist from earlier in this article.
Recoat with preservative oil before long idle periods such as seasonal vehicle layup. A single preventive oil pass every ninety days during dormancy prevents flash rust from forming on unprotected surfaces.
Maintaining and cleaning your M62 crash gear does not require expensive tools or advanced mechanical training. Stick to regular cleaning, thorough drying, careful inspection, and proper lubrication, and your towing and traction hardware will remain dependable whenever conditions demand it. Start today by removing your gear, giving it a complete wash and dry cycle, and running through the inspection checklist before storing it properly.
Frequently Asked Questions
Can I use a pressure washer to clean M62 crash gear?
It is not recommended. High-pressure water forces moisture into shackle threads, pin seams, and turnbuckle barrels where it becomes trapped and causes hidden corrosion. Low-pressure hose rinsing while brushing achieves the same cleanliness without driving water into critical joints.
What type of oil works best for crash gear chains and hooks?
Light machine oil such as SAE 20 or 30 provides good penetration and protection for general use. For shackle pins and threaded hardware, switch to white lithium grease because it adheres longer and resists being thrown off during transit.
How often should I replace damaged M62 crash gear components?
Replace any chain showing visible elongation, cracked welds, deep nicks, or heavy pitting corrosion. Hooks with bent jaws, cracked throat sections, or pins that no longer seat securely must also be replaced immediately. Do not attempt field repairs on load-bearing hardware.
