A failing gear head announces itself with excess vibration, grease leaks, and rough operation. This replacement gear head and trimmer head is machined to OEM dimensions and arrives pre-greased, ready to bolt onto your trimmer shaft. The kit ships with a bump-feed trimmer head, giving you a ready-to-use setup as soon as the gear head is mounted. It is a straightforward fix that restores smooth, quiet cutting.

Compatibility
This gear head fits Husqvarna 128 LX 128LD 128LDX 125L 125LD 128DJX and similar models that share the same shaft interface. Always verify your trimmer’s model and part number against the full compatibility list to make sure the housing mount and drive splines align.
Installation notes
Disconnect the spark plug wire for safety. Loosen the clamp bolt or bolts securing the old gear head to the drive shaft and pull it free. Clean any debris from the shaft end, then slide the new gear head on and align the drive splines. Tighten the clamp hardware evenly to the manufacturer’s torque spec. Attach your cutting head or blade, and run the trimmer briefly to verify smooth, vibration-free operation.
Common questions
Q: Will this 530096295 gear head fit my Husqvarna 128LDX, and does it also work on the 125L and Jonsered BC2126?
Yes, this replacement is made for the Husqvarna 128LX, 128LD, 128LDX, 125L, 125LD, 128DJX, 125R, and 125RJ, and it also fits the Jonsered BC2126 listed in the compatibility details. It’s important to match your trimmer model exactly, since similar Husqvarna units can use different shaft or gear head setups.
Q: Does this come with the T25 trimmer head already, and can I use it to replace a worn gear head on my Husqvarna 125LD?
Yes, this replacement includes both the 530096295 gear head and the T25 trimmer head, so it’s useful when both the gearbox and head need to be changed together. For a 125LD, it’s a direct replacement style part as long as your machine matches the listed compatible models.
Q: What should I check when installing this gear head on a Husqvarna 128LX, and does it need any maintenance after installation?
Before installation, check that the drive shaft engages fully into the new gear head and that the mounting hardware is tightened evenly so the head sits straight. After installation, periodically inspect for grease loss, unusual noise, or wobble at the head, since those are common signs the gearbox needs service or the head was not seated correctly.
