Steel Winch Cable Maintenance for 12V Winches

Winch maintenance

Taking care of your winch cable will make it last longer.

One of the most important parts of your 12V winch to inspect on a regular basis is the cable. If the winch cable breaks under load, you risk significant damage to any vehicle or person in the cable’s path. You also risk damage to the vehicle being recovered, since it could roll back down an incline or slide backwards into a tree, rock, or other object.

Inspect the Cable

Steel cable holds a tremendous amount of energy under load. If it snaps, the force of the lash-back can cause injury or death. Make sure you inspect the wire rope before and after the winching process.

If you notice kinks or fraying, it’s time to replace the cable. Cut wires are also a major warning sign. The more wires get cut, the weaker the cable becomes and the more likely it will be to break under load.

Inspect Adjoining Parts

Inspect the winch hook and hook pin for signs of damage as well. If you notice anything amiss, replace any damaged parts before use.

Protect Your Hands

Always wear thick leather gloves when handling wire cable. Not only can the wire slice into your palms, but the factory coating on the rope can irritate your skin.

Keep It Clean

Wipe off dirt and debris after using your winch rope. Keeping a dirty cable spooled on the winch can lead to rust and corrosion. Wipe it down with a clean rag or use a hose to wash away dirt and debris. If desired, you can add a light coating of oil to the wire rope and winch hook to protect against rust and corrosion.

Prevent Damage

Make sure the winch cable doesn’t rub against anything sharp during the recovery process. Rig up the pull as straight as possible. Sharp angle pulls increase the chances of damaging the winch cable.

Spool Evenly

Keep an eye on the winch cable as it spools into the drum. Don’t let it pile up too much on one side of the drum. Uneven spooling can lead to a bird’s nest (which is very difficult to undo) or cause the cable to pile up high enough inside the winch housing that there’s no room left to spool in more cable.

How to Keep a Winch Motor from Overheating

Winch motor

Take breaks from winching to keep your motor from overheating.

Why does my motor overheat?

Every once in awhile we’ll get a question from a customer who complains that his winch motor is overheating. Most often, the problem is operator error.

If you run an electric winch for too long, especially when it’s close to the maximum load rating, the motor will overheat and possibly overload the contactor.

12-volt electric winches are designed for intermittent duty, which means that you need to take a break and stop winching every once in awhile in order to let the motor cool down.

How do you know if the motor is going to overheat?

If the winch motor is starting to get too hot, the winch will slow down to a low RPM. As the heat builds up in the motor, the winch begins to sound like it’s stalling.

If you continue to winch as the motor approaches stall speed, the contactor (which acts like a circuit breaker) will trip and shut off the motor to prevent permanent damage to your winch.

You’ll also know the motor is about to overheat if the motor is too hot to touch. Stop winching and let the motor rest until it is cool to the touch before you start winching again.

What if I need to keep winching for a long time?

In that case, you’ll need a hydraulic winch. Since hydraulic winches use power from your vehicle’s power steering pump, you can winch all day as long as the engine is running.

Hydraulic winches are best for farming, ranching, and commercial use. Some rig owners prefer hydraulic winches for offroad recovery, but the cost is higher than for electric winches and you’ll need to make sure your vehicle can handle the strain.

Keep Your Winch Working

ATV winch

Use your winch at least once a month, even if just to power the cable out and back in.

Use It or Lose It

We highly recommend using your winch regularly (at least once a month). Even if you don’t need to use the winch for anything, get the motor running and warmed up to keep the winch in good working condition.

Simply power the cable out 5 feet, spool out another 2 feet, and then power back in. This will keep all components in good working condition so that the winch will be ready to use when you need it.

Maintenance

Every so often, check the mounting bolts and electrical connections to make sure they are tight and free of corrosion or damage. Remove any dirt and corrosion that may have accumulated on the electrical connections.

Lubrication

The gearbox and drum bearings are permanently lubricated. No internal lubrication should be required for the life of the winch. Re-lubrication is necessary only after repair or disassembly.

Cable Safety

Always check the condition of the wire or synthetic cable before using. If there are signs of damage that could compromise the safety of the cable, do not use your winch until the cable is repaired or replaced.

Never substitute a heavier or lighter wire rope as a replacement. The rope should have the same diameter and load capacity as the original cable.

Wire Winch Rope Safety

Electric winch

Use the winch strap and leather gloves to spool out winch cable.

Handling wire winch rope is one of the hazards of using an electric winch. Although steel cable is rugged and durable in tough winching conditions, it can also be dangerous if handled carelessly. Here are a few tips on learning to handle wire winch rope safely.

Hand Protection

First off, protect your hands. Stray wires from the cable can tear up your skin if you’re not careful. Wear thick leather gloves any time you handle winch cable, and do not let the rope run through your hands. Grab hold of the winch saver strap to spool out cable, and use the hand-over-hand method to guide the cable back onto the spool.

Dampen the Cable

Although the chances of your winch cable breaking are low, it’s better to be safe than sorry. Dampen the winch cable by draping a heavy mover’s blanket or similar object over the rope. Place it about midway between the winch and the anchor point. Even a tree branch, heavy winter coat, or a length of chain draped over the winch cable will work in a pinch.

If the cable happens to break during the winching process, the extra weight will slow down the backlash effect. Just like a rubber band, your wire rope can snap back if broken. Besides dampening the cable, make sure bystanders are standing well out of the cable’s path. The winch operator should also be careful to stand out of the cable’s path as well. If you are operating the winch from inside your vehicle, consider raising the hood for an extra measure of protection in case the winch rope fails.

Winch Cable Replacement

Check your winch rope often for signs of damage. If your cable shows signs of deterioration beyond the usual wear and tear, replace the cable before using your winch again. For safer cable, consider switching to synthetic winch rope.

Prevent Winch Rope Failure

Winch rope

Winch rope must be underwound on the drum.

Winch rope failure is most often caused by operator error. There’s a lot to know about how to safely operate a winch and take care of your winch rope. One small oversight can lead to winch failure or rope failure.

Causes of Winch Rope Failure

One of the most common causes of rope failure is friction. Overloading the rope is possible but less likely. You can usually tell the reason for the rope breaking by examining the cut ends. If most of the rope fibers are cleanly cut, the culprit is friction—for example, rubbing on a sharp rock or the edge of the winch plate. If the rope fibers are stretched out in long, thinning frays, the culprit is overloading. Sometimes you’ll see a combination of both, in which case a majority of the strands are cut by friction and the rest are frayed by the resulting overload.

Winch Rope Spooling

To prevent damage to your winch rope, make sure the rope is spooled onto the drum in the underwound direction. When the rope comes off the winch drum, it should be coming from underneath the drum, not on top of it. If the rope comes over the top of the winch drum, it will go through the fairlead at an angle, which leads to friction and possibly cutting. If the rope comes out from underneath the drum, it will go through the fairlead straight on, which eliminates friction and cutting.

Angle Pulls

Sharp angle pulls are another possible hazard for your winch rope. Straight pulls prevent the rope from rubbing on the sharp edges of a winch plate or bumper, but if an angle pull is your only way out, make sure the rope is not rubbing against anything. Same thing with sharp rocks. Don’t let the rope fray on a rock or other sharp object while you are winching. Use a rope sleeve to protect the rope.

Do I Need a Winch Cover?

Winch cover

A winch cover keeps rain, dirt, and grime out of your winch.

Constant exposure to the elements can break down your winch line prematurely and allow abrasive grime, sand, and dirt into your winch’s gears and other moving parts. To make your winch and cable last as long as possible, use a winch cover when you are not using the winch.

For Synthetic Rope

If you run synthetic line on your winch, a cover can slow down the fading. Even with UV inhibitors, exposure to the sun will eventually fade the color on your rope. Synthetic line is designed to withstand harsh exposure to the elements, since it was originally developed for marine use, but it will last longer (and look better) if you keep it covered.

For Steel Cable

If you run steel cable, a winch cover keeps out abrasive substances and protects against rain, UV rays, and other elements. Mud, dirt, road grime, salt, sand, and ice can get into your winch gears and other winch parts and act like sandpaper, keeping your winch from running smoothly and possibly causing damage.

Even with a winch cover, it’s still important to use and maintain your winch properly if you want to get the most life out of it. There’s no substitute for taking good care of your winch with regular maintenance and cleaning.

How to Replace a Winch Cable

ATV winch

Replace the cable on your winch with the same diameter and length.

When replacing the cable on your ATV or recovery winch, use the cable width and length recommended by the manufacturer. Never replace cable with heavier or lighter rope. If the cable is too thick, you won’t be able to fit as much cable on the spool. If it’s too thin, it won’t have enough strength for the load rating on the winch.

If preferred, you can switch to synthetic rope for safer winching, plus no frayed wire or kinked cable.

You do not need to remove the winch from the vehicle (unless the winch is mounted in a way that restricts access to the drum) or take the winch apart to replace the cable.

How to Replace Wire Winch Cable

  1. Spool out the entire length of the old cable.
  2. a
  3. Remove the winch cable where it is attached to the drum. Release the tension on the cable and push on the end of the cable where it feeds through the small hole in the drum. If the rope is kinked over and pulled tight into the drum, simply push the cable out of the hole until you can straighten out the kinked cable. Then pull the end of the cable through the hole to remove it from the drum. If the cable will not come out by pushing, try using a pin punch (or something similar) and a hammer to drive the metal button or keeper out of the hole. If your cable is attached to the drum with a bolt, you’ll need to remove the bolt to take off the cable.
  4. a
  5. Attach the new cable to the drum. For wire rope, slip the end of the cable through the hole in the drum and tighten the set screw to hold the cable in place. For recovery winches, apply Loctite (or similar product) to the cable clamp thread to prevent loosening of the screw. Tighten the clamp screw (but be careful not to overtighten).
    a

    If you are replacing your wire cable with synthetic rope, push the end of the rope into the hole in the drum. Pull the rope through the hole, wrap it around the underside of the drum and over the top, tuck the rope underneath itself where it exits the drum, and then depress the end of the rope back into the hole in the drum. You may need to use a screwdriver to force the end of the rope into the hole.

  6. a
  7. Respool the cable in the underwound direction so that the winch spools in and out correctly. Respool under a load of at least 500 pounds so that the outer layers will not draw down into the inner layers.

ATV Winch Cleaning and Maintenance Guide, Part 3

This is the third and final part in this series on ATV winch cleaning. See ATV Winch Cleaning and Maintenance Guide Part 1 and Part 2 for steps 1 through 22 on how to clean your ATV winch.

Thanks to Todd Sandberg for the following information and photos on cleaning and maintaining your ATV winch.

Winch Cleaning Instructions (Steps 23-32)

a

Step 23

Once the motor is cleaned up, place the motor end cap on your table; then carefully put the motor into position on the end cap. Ensure that the armatures are aligned properly and that all 4 springs are in their respective areas and not bound up.

Position the motor on the end cap

Step 25

Reinstall motor housing bolts into motor housing; then mate that assembly to the gear housing, making sure that the motor end cap never loses contact with the motor and motor housing. If this happens, redo steps 23 and 24, as you risk having the armatures out of place and damaging your winch. Once everything is back together properly, tighten down the motor housing bolts to secure the motor housing assembly to the gear housing assembly. If you wish to add another level of water protection, you can run a small bead of silicone on the gear housing so that once the motor housing is mated up, it forms a good weather seal. That is optional, but it won’t hurt anything, so it’s worth your time in my opinion.
