Homelite Trimmer Head Removal: Replace Model U T 33650A (Pro Fix Tips)
Homelite Trimmer Head Removal & Replacement: Pro Fix Tips for Model UT 33650A
As someone who’s spent countless hours in the woodshop and tending to my property, I understand the frustration of dealing with a malfunctioning trimmer head. It’s a common issue, but with the right knowledge and tools, it’s a problem you can easily solve yourself. Not only will this save you money on repair costs, but it’ll also give you a sense of accomplishment and a deeper understanding of your equipment.
Understanding the Homelite UT 33650A Trimmer Head
Before diving into the removal process, it’s crucial to understand the specific type of trimmer head on your Homelite UT 33650A. This model typically uses an auto-feed or bump-feed head, which dispenses line when you tap it on the ground. Knowing this will help you select the correct replacement and avoid compatibility issues.
- Auto-Feed vs. Bump-Feed: Auto-feed heads automatically release line at intervals, while bump-feed heads require you to “bump” the head on the ground to advance the line. The UT 33650A typically uses the bump-feed system.
- Line Diameter: The UT 33650A usually takes line with a diameter of 0.065″ or 0.080″. Using the wrong diameter can lead to feeding problems.
- Thread Direction: The thread direction for the trimmer head is usually left-handed (counter-clockwise to loosen). This is a critical detail to remember when removing the head.
Safety First: Preparing for Trimmer Head Removal
Safety is paramount when working with any power tool. Before you even think about touching the trimmer head, take these precautions:
- Disconnect the Power: This seems obvious, but it’s the most important step. Remove the spark plug wire (if it’s a gas-powered trimmer) or disconnect the battery (if it’s electric).
- Wear Safety Gear: Eye protection is a must. Debris can fly up unexpectedly during the removal process. Gloves are also recommended to protect your hands.
- Clear the Area: Make sure your work area is clear of obstacles and distractions.
- Cool Down: If you’ve been using the trimmer, let it cool down completely before starting any maintenance.
Tools You’ll Need
Having the right tools on hand will make the removal process much smoother. Here’s what I recommend:
- Wrench or Socket Set: The size will depend on the specific nut or bolt securing the trimmer head. Usually, a 13mm or 19mm socket is needed.
- Screwdriver: A flathead screwdriver can be useful for prying or loosening parts.
- Piston Stop Tool (Optional): This tool locks the engine in place, making it easier to loosen the nut holding the trimmer head. If you don’t have one, you can use a rope inserted into the spark plug hole, but be careful not to damage the piston.
- Penetrating Oil (e.g., WD-40): If the nut is stuck, penetrating oil can help loosen it.
- Gloves: Protect your hands.
- Eye Protection: Safety glasses or goggles are essential.
Step-by-Step Trimmer Head Removal
Now, let’s get down to the nitty-gritty. Here’s how to remove the trimmer head from your Homelite UT 33650A:
- Secure the Shaft: Use the piston stop tool (or rope method) to lock the engine in place. This prevents the shaft from spinning while you’re trying to loosen the nut.
- Locate the Nut: Identify the nut or bolt that secures the trimmer head to the shaft.
- Apply Penetrating Oil (If Needed): If the nut is rusty or stuck, spray it with penetrating oil and let it sit for a few minutes.
- Loosen the Nut: Using your wrench or socket, turn the nut clockwise to loosen it. Remember, most trimmer heads have left-handed threads. So, righty-tighty, lefty-loosey is reversed. This is a common mistake that can lead to frustration.
- Remove the Trimmer Head: Once the nut is loose, you should be able to unscrew the trimmer head by hand.
- Inspect the Shaft: Check the shaft for any damage or wear. Clean it with a wire brush to remove any debris.
Pro Tip: If you’re having trouble loosening the nut, try heating it with a heat gun (carefully!) to expand the metal. This can sometimes break the bond between the nut and the shaft.
Selecting the Right Replacement Trimmer Head
Choosing the right replacement trimmer head is crucial for optimal performance and longevity. Here are some factors to consider:
- Compatibility: Make sure the replacement head is specifically designed for the Homelite UT 33650A. Check the manufacturer’s website or consult with a local hardware store.
- Type of Head: Decide whether you want to stick with a bump-feed head or upgrade to a different type, such as an auto-feed or fixed-line head.
- Line Capacity: Consider the amount of line the head can hold. A larger capacity means less frequent reloading.
- Durability: Look for a head made from high-quality materials that can withstand regular use.
- User Reviews: Read reviews from other users to get an idea of the head’s performance and reliability.
Data Point: According to a 2023 survey by Outdoor Power Equipment Magazine, users who opted for high-quality replacement trimmer heads experienced a 25% reduction in line breakage and a 15% increase in overall trimming efficiency.
Installing the New Trimmer Head
Installing the new trimmer head is essentially the reverse of the removal process:
- Clean the Shaft: Make sure the shaft is clean and free of debris.
- Apply Grease (Optional): Applying a small amount of grease to the threads can help prevent the nut from seizing in the future.
- Thread on the New Head: Screw the new trimmer head onto the shaft by hand, turning it counter-clockwise.
- Tighten the Nut: Use your wrench or socket to tighten the nut, turning it counter-clockwise. Make sure it’s snug, but don’t overtighten it.
- Remove the Piston Stop Tool: Remove the piston stop tool (or rope).
- Test the Trimmer: Reconnect the spark plug wire or battery and start the trimmer. Test the trimmer head to make sure it’s feeding line properly.
Pro Tip: When installing the new head, pay close attention to the orientation of the washers and spacers. Incorrect placement can cause the head to vibrate or malfunction.
Troubleshooting Common Issues
Even with careful installation, you might encounter some issues. Here are a few common problems and how to solve them:
- Trimmer Head Won’t Feed Line: This could be due to several reasons:
- Incorrect Line Diameter: Make sure you’re using the correct line diameter for your trimmer head.
- Line Tangled Inside the Spool: Disassemble the head and untangle the line.
- Worn Spool: Replace the spool if it’s worn or damaged.
- Incorrect Line Winding: Make sure the line is wound correctly on the spool.
- Trimmer Head Vibrates Excessively: This could be due to:
- Loose Nut: Tighten the nut securing the trimmer head.
- Damaged Shaft: Inspect the shaft for any damage or bending.
- Unbalanced Trimmer Head: Replace the trimmer head if it’s unbalanced.
- Trimmer Head Falls Off: This is usually due to:
