198386-5 for Makita Bump & Feed String Trimmer,Linetrimmer Head Spool Assembly,Replacement XRU11Z XRU12 XRU04Z, fits All M8x1.25LH Trimmers

What It Is

This is the Makita 198386-5 bump & feed spool assembly, a direct replacement for the trimmer head on Makita XRU11Z, XRU12, and XRU04Z string trimmers. It holds and feeds trimmer line when you tap the head on the ground, keeping your trimming work continuous.

Fitment & Compatibility

Before buying, confirm your trimmer model is one of these: XRU11Z, XRU12, XRU04Z. The spool assembly fits all trimmers with an M8x1.25 left-hand threaded shaft — this includes most Makita cordless trimmers, but not all. Check your existing head’s thread size and direction (left-hand means it tightens counterclockwise). If you have a different Makita model (e.g., XRU09, XRU13), measure the shaft thread; M8x1.25 LH is not universal across the brand. This is an OEM Makita part, not aftermarket, so fit is exact for compatible models. No deck size to worry about — it’s a head-only replacement.

Key Things to Know

• Quality concerns: With a 3.4/5 rating from only 22 reviews, some users report the bump-feed mechanism jamming or the head cracking after moderate use. Check reviews for your specific model.
• Installation difficulty: Easy if you have the right tool — use a hex wrench or screwdriver to lock the shaft, then unscrew the old head counterclockwise (left-hand thread). The new spool comes pre-wound with line, so no winding needed.
• Common gotcha: The pre-wound line may be thinner (0.065” or 0.080”) than what you prefer for thick weeds. You can re-spool with heavier line, but the head’s capacity is limited.
• Left-hand thread trap: Do not force the new head on clockwise — it tightens left-hand. Cross-threading will ruin the shaft.

Should You Buy It

Buy this if you own a Makita XRU11Z, XRU12, or XRU04Z and need a quick, drop-in replacement without winding line. Skip it if you want a more durable head for heavy-duty use, or if your trimmer has a different thread size — in that case, look for a universal head with adapters.
