Proper storage and handling of your Nashville Stroker Crank are critical to preserving its precision-ground surfaces and ensuring long-term engine reliability. Whether you are between builds, waiting for parts, or simply performing seasonal maintenance, taking the right steps to protect this high-performance component can save you from costly repairs and lost horsepower. This guide covers industry-tested methods for cleaning, rust-proofing, handling, and storing your stroker crank so that it remains in race-ready condition.

Why Storage and Handling Matter for a Stroker Crank

A Nashville Stroker Crank is machined to extremely tight tolerances. The main and rod journals, fillets, and oil passages are designed to withstand high RPMs and heavy loads. Even minor surface damage, like a scratch or a spot of rust, can throw off the balance, accelerate bearing wear, or cause a catastrophic failure. Moisture, dirt, and careless handling are the three biggest enemies of a stored crankshaft. By understanding how to control these factors, you protect your investment and ensure that when the crank goes back into the engine, it performs as intended.

Preparing the Stroker Crank for Storage

Thorough Cleaning

Before any storage or preservation step, the crankshaft must be completely clean. Use a high-quality degreaser and a soft-bristle brush to remove all traces of old oil, grease, metal shavings, and debris. Pay special attention to the oil holes and keyways. A parts washer or a solvent bath works well for this step. Once clean, rinse the crank thoroughly with clean solvent or water, depending on the degreaser's instructions.

Critical: Do not use abrasive pads or steel wool on the journals. Even non-woven abrasive pads can leave micro-scratches that become stress risers. Stick to soft brushes and lint-free cloths.

Complete Drying

After cleaning, the crank must be dried immediately to prevent flash rust. Compressed air directed into the oil passages and around the journals will remove moisture. Follow up with a clean, lint-free microfiber cloth. If the ambient humidity is high, consider placing the crank in a warm, dry area (like near a low-heat oven) for 30 minutes to ensure no trapped water remains.

Inspecting for Damage Before Storage

Use this opportunity to inspect the crankshaft for any pre-existing issues. Check the main and rod journals for scoring, pitting, or discoloration. Use a micrometer or caliper to measure journal diameters and compare to factory specs. Look for cracks around the keyway, oil holes, and radii. Document the measurements with photos or written notes — this baseline data will be valuable when you reassemble the engine. If you find any abnormalities, address them now rather than after storage.

Applying a Rust Inhibitor

Once the crank is clean and dry, apply a generous layer of a rust-inhibiting oil or preservative. Products like WD-40 Specialist Corrosion Inhibitor, Boeshield T-9, or CRC SP-400 are specifically designed for long-term metal storage. Even a conventional high-viscosity engine oil works, but it may not last as long. The goal is to create a barrier that prevents moisture from reaching the metal.

Apply the inhibitor with a clean brush or spray, making sure to coat every surface — especially inside the oil passages. Use a small nozzle to inject preservative into each oil hole. After coating, let the crank sit for a few minutes to allow the excess to drain off.

Wrapping the Crankshaft

After the inhibitor has been applied, wrap the crankshaft in a material that will keep out dust and moisture while allowing some breathability. Good options: silicone-impregnated cloth (such as Zip-It or VCI paper) or heavy-duty food-grade plastic wrap (the type used for pallet wrapping). Avoid newspaper or regular cloth, which can retain moisture and shed fibers.

For extra protection, place the wrapped crank inside a large, sealed plastic bag with a few moisture-absorbing desiccant packs. Squeeze out as much air as possible before sealing. Label the bag with the date, part number, and any inspection notes.

Safe Handling During Maintenance

Proper Workwear and Cleanliness

Always wear clean, lint-free gloves when handling the crankshaft. Bare hands transfer oils, acids, and salts that can trigger corrosion. Use nitrile or latex gloves, and change them if they become contaminated. Work in a clean, dust-free area. If possible, set up a dedicated workbench with a clean mat for engine internals.

Correct Gripping and Support Points

The strongest way to handle a crankshaft is by holding the main journals — never by the rod throws or the snout. The main journals are the structurally robust areas designed to carry the crank's weight. Supporting the crank by the rod throws can bend the connecting rod pins or distort the crank over time, especially if dropped or set down unevenly.

When moving the crank, use both hands, one under each end main journal. For larger stroker cranks (e.g., 4340 forged units), consider using a padded handling sling or a lifting hook designed for crankshafts. Never let the crank rest on its flywheel mounting flange or the harmonic balancer snout.

Tool Selection and Workspace Setup

Use only clean, oil-free tools when working near the crankshaft. Any grit or metal chips from wrenches or sockets can get embedded in the bearing surfaces. Pad your workbench with a clean towel or a rubber mat. Avoid granite or steel benchtops that can mar the crank's surface if accidentally dropped.

If you need to rotate or position the crank, use padded wooden blocks or plastic bearing separator tools. Never clamp the crank directly in a vise — always use soft jaws or a specialized crankshaft fixture.

Avoiding Common Handling Mistakes

One of the most frequent errors is allowing the crankshaft to come into contact with floor surfaces or dirty tools. Even a tiny particle of sand or metal can create a deep scratch when the crank is moved. Another mistake is leaning the crank against a wall or a tire — this can cause it to bend or fall. Always store and handle the crank horizontally on a flat, padded surface such as a dedicated crankshaft storage rack.

Also, never use the crank as a lever or a pry bar. The precision-machined surfaces are not designed for that kind of stress. Treat the crank like a delicate measuring instrument, because functionally it is one.

Best Practices for Long-Term Storage

Environmental Control

The ideal storage environment for a stroker crank is a climate-controlled space with low humidity (below 40% RH) and stable temperatures between 60°F and 75°F (15°C to 24°C). Avoid basements, garages that see high humidity, or attics that can become extremely hot. Temperature swings cause condensation inside the packaging, which defeats the corrosion inhibitor.

If you cannot control the environment, invest in a large desiccant dehumidifier for the storage area, or place the sealed crank bag inside a sealed plastic tote with an extra pound of silica gel. Check the silica gel monthly — recharge it in the oven when it becomes saturated (most color-changing gels turn from blue to pink).

Using Dedicated Storage Racks or Cases

For the highest level of protection, use a storage rack that supports the crank by its main journals. Many aftermarket manufacturers offer plastic or aluminum racks that cradle the crank. Alternatively, you can build a simple wooden rack with cutouts lined with felt or foam. The rack should hold the crank level and prevent it from rolling.

Avoid storing the crank directly on concrete floors, as concrete wicks moisture and can cause condensation. Even a piece of wood or rubber mat underneath will help. If the crank is stored in its box, ensure the box is sturdy and that the crank is not pressing against the sides. Custom-fitted foam inserts are ideal.

Periodic Inspection and Maintenance

Even the best storage method is not set-and-forget. Schedule a monthly inspection. Unwrap the crank, check for any signs of rust, and compare the surface against the baseline photos. Look at the oil holes — if you see brown discoloration, reapply the rust inhibitor. Rotate the crank slightly on the rack to prevent moisture from settling in one spot.

If you notice any rust starting, remove it immediately with a very fine scotch-brite pad (gray or white only) and plenty of oil — do not use sandpaper. Then re-clean and re-inhibit the area. A light rust that is caught early can be removed without damaging the journal finish.

Re-Oiling and Re-Wrapping Schedules

Rust inhibitors gradually evaporate or drain off. For storage periods beyond 3 months, plan to re-oil the crank every 60 days. This is especially important if you used a conventional engine oil rather than a dedicated long-term preservative. For storage over a year, consider using a heavy-duty cosmoline-type coating that can last for years. Cosmoline is messy to remove later, but it is the gold standard for long-term metal preservation.

When re-wrapping, always use fresh plastic or cloth. Old wraps can trap contaminants or become brittle and shed particles. Replace desiccant packs when they show signs of saturation.

Reinstalling the Stroker Crank After Storage

Pre-Installation Cleaning

When you are ready to build the engine, remove the crank from storage and carefully unwrap it. Inspect it again for any new damage or corrosion. The preservative oil must be fully removed before installation. Use a solvent-based cleaner (e.g., brake cleaner or mineral spirits) and a clean brush to degrease the entire crankshaft. Follow with a soap-and-water wash to remove any solvent residue, then blow dry with compressed air.

If the crank has been stored with a heavy rust inhibitor like cosmoline, you may need to use a specific remover. Heating the crank gently (using a heat gun set to low, never a torch) can soften the coating for easier removal. Wipe off the melted coating with clean lint-free cloths.

Checking Tolerances and Clearances

After cleaning, re-measure the journal diameters and compare them to the original spec. Even if storage was perfect, thermal expansion and contraction over time can cause very slight changes. Verify that all oil passages are clear by spraying solvent through them. Key point: Never assume the crank is still in spec just because it was when you stored it. Use a micrometer and a straightedge to check for warpage. A quick spin test on V-blocks can confirm that the crank runs true.

Finally, install the crank using the same cleanliness protocols you used during storage. Lubricate the journals with assembly lube before placing the bearings. After installation, torque the main caps to spec and turn the engine over by hand to confirm smooth rotation. Your careful storage and handling will pay off with a smooth, reliable engine.

Common Pitfalls and How to Avoid Them

Even experienced engine builders sometimes make mistakes with crankshaft storage and handling. Here are a few of the most common pitfalls and the simple fixes:

  • Pitfall: Storing the crank vertically. Over time, weight can cause the crank to bend at the rod throws. Avoidance: Always store horizontally on a rack that supports the main journals.
  • Pitfall: Using acidic or chlorinated solvents for cleaning. These can leave residues that attack the metal. Avoidance: Use pH-neutral degreasers and avoid chlorine-based brake cleaners.
  • Pitfall: Exposing the crank to high heat (e.g., near a furnace or direct sunlight). Heat can warp the crank and cause the oil to polymerize into a sticky film. Avoidance: Store in a temperature-stable area away from HVAC vents.
  • Pitfall: Forgetting to label the stored crank. If you store multiple cranks, you can mix them up. Avoidance: Attach a durable tag with the part number, date, and measured specs.
  • Pitfall: Skipping the monthly inspection. Small issues become big problems over months. Avoidance: Set a calendar reminder and stick to it.

Summary of Best Practices

To protect your Nashville Stroker Crank during storage and handling, remember these core steps:

  • Clean thoroughly with non-abrasive methods and dry completely.
  • Apply a high-quality rust inhibitor and wrap in VCI paper or sealed plastic with desiccants.
  • Handle only by the main journals, wearing clean gloves, and use padded supports.
  • Store horizontally in a climate-controlled, dry environment on a dedicated rack.
  • Inspect monthly, reapply preservative every 2–3 months, and recheck measurements before reinstallation.

By following these guidelines, you ensure that your high-performance stroker crank delivers the power and reliability it was designed for — even after months or years of inactivity. A little investment in proper storage and handling today can prevent a major headache and expense down the road.
