Makita 345237-5 Spare Part - CRANK PLATE 4340/SMA400

Makita 345237-5 — genuine Makita crank plate for jigsaws

Description:

A small but critical stamped-steel crank plate that forms the heart of the jigsaw linkage. This original Makita part converts the motor’s rotary motion into the reciprocating/orbital motion of the blade, restoring smooth stroke, accurate tracking and lower vibration when the original plate is worn, bent or cracked. Sold as a single replacement plate, it’s made to Makita’s original specification so it aligns with the tool’s linkage and mating parts for reliable performance.

What it fits:

Commonly used in Makita jigsaw models including (but not limited to) BJV140, BJV180, DJV180, DJV182 and the 4340 / 4341 / 4350 series (examples: 4340CT, 4340FCT, 4341CT, 4341FCT, 4350CT, 4350FCT, 4351FCT). Confirm your tool’s parts diagram or the reference number 345237-5 on your service sheet before ordering.

Notes for fit and replacement:

- The plate is part of the jigsaw’s crank/linkage assembly and is typically secured with the tool’s small hex socket bolts (M5-style on the related parts diagrams) and works together with the leaf spring and base plate within the lower linkage. Replace the plate if you see play, cracking or uneven blade stroke.

Why this part:

If your jigsaw produces a shaky, uneven cut, excessive vibration, or the orbital action no longer functions cleanly, a worn or bent crank plate is a common cause. Swapping in this genuine Makita 345237-5 crank plate restores correct geometry in the linkage so the tool cuts as intended.
