What this video covers
A MAX-PROP feathering propeller disassembly is walked through step by step, covering barnacle removal, zinc removal, cotter pin extraction, and hub disassembly. Muriatic acid applied by paintbrush cleans barnacle growth from the prop; a respirator and gloves are required for that step.▶ 0:04 Cotter pins come out with needle-nose pliers and a screwdriver to bend stubborn ones.▶ 0:55 A number-5 Allen key driven by a weak impact wrench cracks loose the hub bolts without forcing them.▶ 1:04 Before disassembly, a reference line is marked on the hub to record the feathered position, because the MAX-PROP's internal cone carries pitch markings — in this case, letter B aligned with a dimple — and each blade is numbered and must be reinstalled in its original order.▶ 2:15 A second pitch reference, marked N with a double dimple on the cog, is photographed for reassembly.▶ 2:59 Two small flat-sided retaining pins hold the nut in place; these are removed before the nut, then the cone taps off with minimal force — no gear puller needed.▶ 3:23 Recording pitch alignment marks before pulling the cone is the critical step to avoid incorrect blade pitch on reassembly.
