Makita SHAFT A EM400/EY400/KR400 - 326088-5

Original Makita Shaft A — part no. 326088-5. Precision-machined replacement shaft designed to sit inside the shaft pipe of Makita couple-shaft attachments and engage the gear-case/cutter shaft assembly; it’s the wear-prone internal shaft that’s secured by the retaining ring (e.g., S‑7, Makita ref 961003‑8) and mates with the cutter/gear assembly.

Fits Makita Models : EY400MP / EY401MP / EM400MP / EM404MP / EM406MP / EN400MP and EN401NP

Why this part matters: if your attachment’s internal shaft is bent, worn or has excessive play the gearbox alignment and cutter operation will be affected; replacing it restores correct shaft alignment and engagement with the cutter / gearcase so the attachment runs smoothly.

What you’re getting: the original Makita Shaft A (326088‑5), ready to drop into the shaft pipe and be secured with the factory retaining ring — a direct-fit replacement for the shaft component shown in the official Makita parts breakdowns for the listed attachments.
