Makita LEAD FLANGE GA4541/41C/5041&C - 310514-4

Makita 310514-4 — Lead Flange (original Makita)

A genuine Makita lead flange designed to mount on the grinder spindle and secure the outer face of the cutting or grinding wheel. It indexes the wheel concentrically and transfers torque from the spindle to the wheel so the tool runs true and the wheel is held reliably during use.

This part is listed in Makita parts diagrams as part no. 310514-4 and is used on both 125 mm and 150 mm Makita angle grinders depending on the model — GA5091 (125 mm), GA035G (150 mm) and several of Makita’s 125 mm cordless grinders such as the DGA514 / DGA513.

Example compatible models in Makita parts lists): DGA513, DGA514, DGA506, DGA508, DGA517, DGA518, GA035G (150 mm), GA5041 (125 mm), GA5091 (125 mm) — the flange is the wheel-side mating flange in these model diagrams. If your grinder’s parts diagram shows part number 310514-4 (or the lead flange at the spindle/wheel assembly), this is the original Makita replacement.

Notes for fitment: the lead flange installs on the tool spindle and works together with the inner flange/locking nut assembly (refer to your model’s exploded parts list for the inner flange and lock‑nut part numbers and the correct wheel diameter — 125 mm or 150 mm — for your tool). Ordering by part number 310514-4 ensures you receive the original Makita lead flange specified in Makita parts diagram.
