Don’t Trash Your Trimmer: The Ultimate Motor Fix
Your 18V LXT cordless string trimmer is an essential tool for keeping your property looking sharp. But clearing overgrown weeds and accidentally hitting chain-link fences can put a massive strain on the internal components. When a trimmer is pushed past its limit, the DC motor takes the hit. If you’ve noticed a burning electrical smell, smoke pouring from the vents, or a total loss of power, your motor has likely burned out.
Instead of spending over $130 on a brand new bare tool, you can rebuild your reliable workhorse with the FixPartHub 629932-8 Replacement Motor. This simple fix takes less than 30 minutes and saves you a significant amount of money.
Precision Engineering for Garden Tools
This isn’t a generic hobby motor. The 629932-8 (and cross-compatible 629931-0) replacement motor is specifically wound to deliver the high torque and 7,800 no-load RPM required by professional string trimmer lines. It fits seamlessly into the clamshell housing of the trimmer head, ensuring perfect alignment with the cutting spool shaft.

👨🔧 FixPartHub Pro Repair Tip: Before you order a new motor, verify that your battery is fully charged and that the trigger switch hasn’t failed. If the trimmer is completely unresponsive without any burning smell, the switch might be the culprit. If you smelled smoke or the motor housing was extremely hot to the touch before it died, this 629932-8 replacement motor is exactly what you need. Remember to take a photo of the wire connections (Positive/Negative) before disconnecting the old motor!

Yes. This premium aftermarket DC motor is specifically engineered to be fully compatible with popular Makita cordless string trimmers (often called weed eaters or weed wackers), specifically the 18V LXT DUR181 and the 14.4V DUR141 models. It serves as a direct drop-in replacement for OEM part number 629932-8 to restore your tool’s cutting speed.
Trimmer motors typically fail from thermal overload when forced to cut through extremely thick, overgrown, or wet grass. If your weed wacker suddenly loses RPMs (spinning sluggishly), emits a strong electrical burning smell, or the plastic motor housing gets painfully hot to the touch, the internal copper coils are fried. A complete motor replacement is the only solution.
After desoldering the wires from your dead motor and soldering them onto this new aftermarket motor, you must clean the housing. Crucial Pro Tip: Before sealing the clamshell back up, use a brush or compressed air to completely remove all the packed dirt and wet grass clippings inside the trimmer head. Blocked cooling vents are the number one cause of premature motor failure in lawn tools. Ensuring proper airflow will double the lifespan of your new motor.
