Original Makita lever (Lever 51), part no. 416370-1 — a direct replacement lever used in the handle/trigger assembly of Makita jigsaws.

This small replacement lever interfaces with the inner lever (344331-0) and compression spring (233101-1) and is secured in the handle with the countersunk M4x6 screw specified in the parts diagram — it was introduced as the updated Lever 51 to replace earlier versions.

Fits: commonly listed for Makita jigsaw models 4304T and 4334D (service documentation also references related 4305T changes in the same lever family).

Why this part matters: if your jigsaw’s handle/lock mechanism is loose, stuck, or broken, replacing this genuine Makita lever restores proper actuation and alignment without having to replace larger assemblies — sold as a single replacement lever.
