Genuine Makita 213436-6 — Oil Seal 28: a precision single oil seal listed by Makita as "OIL SEAL 28" (28 mm reference) used to retain lubricant and keep dust and debris out of the barrel/gear area on SDS‑Plus rotary hammers. Built to the original Makita specification, this seal is the exact replacement you need when repairing the crank/barrel assembly; it's a small, low‑profile rubber sealing lip that fits into the tool’s seal bore and seats around the shaft to stop oil migration and protect internal components.
Fits (examples): Makita HR3000C, HR3210C and HR3210FCT — check your model’s spare‑parts diagram to confirm the same item number and location before installing. This is a genuine Makita replacement used across multiple Makita parts diagrams for SDS‑Plus rotary hammers.
Note: if you’re ordering a single seal for a repair, match the part number 213436‑6 to your tool’s parts list to ensure compatibility — this part is intended specifically for rotary‑hammer assemblies and listed as Oil Seal 28 in Makita parts list.. Using the exact Makita parts will keep other power tool parts functioning correctly and prevent premature wear.
