Genuine Makita shoulder sleeve (part 257742-9) — a small flanged guide sleeve used inside the drive assembly of Makita reciprocating saws to locate moving parts, cut down play and noise, and restore smooth, accurate stroke action.
Key details:
- Part number: 257742-9 (SHOULDER SLEEVE 14).
- Typical fit: designed for Makita JR3060T and also used on JR3070CT reciprocating saws.
- Form and finish: flanged, cylindrical guide sleeve (usually black), made to Makita’s original specification to resist vibration and repeated load.
- Size (approximate): manufacturer listings show a size of roughly 28 mm (for reference when checking fit).
- Supply: sold singly (one sleeve per part number).
Why this part matters: if your saw shows excessive lateral play at the blade holder, irregular cutting, or rattling from the slider area, replacing this shoulder sleeve restores correct alignment between the slider/guide components and protects mating pins and housings from accelerated wear. Installation is straightforward during routine service or rebuilds — it locates into the slider/gear housing as shown on the exploded parts diagram for these models.
This is the original Makita replacement sleeve built to the tool’s specifications, intended to return your reciprocating saw to proper mechanical alignment.
