Clean the mounting surface before installation and inspect the related sealing components before reassembly. Replace the cover O-ring and any worn check-valve parts if the service diagram calls for them. Tighten the mounting hardware evenly and avoid forcing seized screws, as cracking or distorting the valve body can cause hydraulic leakage or loss of reverse lock pressure.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eRelated Service Parts\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCommon related reverse lock valve service components may include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e25-45711\u003c\/strong\u003e — valve cover O-ring reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30-45712\u003c\/strong\u003e — valve\/check ball reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-45713\u003c\/strong\u003e — retaining washer reference\u003c\/li\u003e\n\u003cli\u003eReverse lock valve mounting screws and related hydraulic hardware as shown in the factory diagram\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eConfirm all related parts by the exact Mercury\/MerCruiser reverse lock valve diagram before ordering.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e45528A2\u003c\/strong\u003e — Mercury\/MerCruiser service part number\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e45528A 2\u003c\/strong\u003e — alternate printed\/catalog spacing reference\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e45528\u003c\/strong\u003e — base\/reference number; verify by diagram and application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eReverse lock valve parts are tied closely to the specific trim system and drive generation.
