Craftsman Large Oil Filter Wrench

Trying to remove an oil filter that’s been over-tightened or simply stuck can be a frustrating experience, especially if you don’t have the right tool for the job. I recently had the chance to put the Craftsman Large Oil Filter Wrench, model CMMT14121, to the test, and it proved to be a reliable companion in the garage.

First Impressions and Build Quality

The first thing that struck me was the tool's robust build quality. The wrench features a stainless-steel auto-adjusting band designed to fit oil filters ranging from 3-3/4 inches to 4-3/8 inches. This versatility is immediately apparent and makes it suitable for a wide range of vehicles, from sedans to larger diesel engines. The full polish chrome finish gives it a sleek look, but more importantly, it seems to add a layer of durability to the tool.

Handling and Comfort

One of the standout features of this oil filter wrench is the swivel handle. This aspect of the design allows for easy maneuverability, which is crucial when working in tight spaces under a vehicle. The handle can rotate, giving you the flexibility to approach the filter from different angles. This is a significant advantage over traditional fixed-handle wrenches that can be cumbersome in confined spaces.

The comfort grip handle is another thoughtful addition. Made from a soft, yet sturdy material, it provides a firm hold even when your hands are greasy. During my use, I found that the grip didn’t slip and allowed me to apply the necessary torque to loosen stubborn filters without straining my wrist.

Performance

The performance of the Craftsman Large Oil Filter Wrench is where it truly shines. The dimpled band design is a game-changer. The dimples increase the grip on the filter, reducing the likelihood of slippage. This is particularly useful when dealing with over-tightened filters or those that have become slick with oil.

In one instance, I had to remove an oil filter that had been over-tightened by a lube shop. Traditional tools like large channel locks were ineffective, but this wrench managed to grip and turn the filter without damaging it. The auto-adjusting band mechanism worked flawlessly, accommodating the filter size without requiring constant readjustment.

For those working on larger diesel engines, this tool is a boon. I used it on a big diesel generator, and it performed admirably, gripping the large filter securely and allowing me to remove it without any fuss. The stainless-steel band didn’t show any signs of wear or deformation after multiple uses, which speaks to its durability.

Durability and Maintenance

Craftsman backs this tool with a full lifetime warranty, which is always a reassuring sign of quality. The stainless-steel construction and full polish chrome finish make it resistant to rust and corrosion, two common issues in tools exposed to oil and other automotive fluids. Cleaning the wrench is straightforward; a quick wipe down with a cloth is usually sufficient to keep it in good condition.

Pros and Cons

Pros:

• Adjustable Band: Fits a wide range of oil filter sizes, adding versatility.

Final Thoughts

Its adjustable band, swivel handle, and dimpled design are all features that contribute to its excellent performance and ease of use.
