The Makita 310778-0 Arm is a genuine OEM spare part designed to restore the internal linkage mechanism of selected Makita pin nailers, including the DPT353RTJ, DPT353Z, and PT354DZ models. Precision-engineered to original manufacturer tolerances, this replacement arm is constructed from hard-wearing metal to deliver a reliable, accurate fit. It is designed to restore smooth, positive movement within the firing and feed mechanism when the original arm has worn, bent, or failed under regular use. Suitable for second-fix carpenters and finish tradespeople who depend on consistent pin placement, this part helps keep your nailer driving cleanly and accurately into timber and sheet materials. The smooth, well-finished contact surfaces help reduce friction and minimise further wear during operation. As a genuine Makita part, the 310778-0 offers assured compatibility with the listed models and eliminates the uncertainty associated with aftermarket alternatives. It is straightforward to fit using standard hand tools, making it a practical choice for both on-site maintenance and workshop servicing.
