This drop-in style filter helps maintain clean transmission fluid flow and protects internal gearbox components from contamination during normal operation. Current references identify this kit as a ZF transmission filter with O-rings and a direct service replacement for compatible ZF 45, 63, 68, 80, and 85 series marine transmissions.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOriginal-equipment ZF Marine \/ ZF Hurth transmission filter kit.\u003c\/li\u003e\n\u003cli\u003eDrop-in style transmission oil filter.\u003c\/li\u003e\n\u003cli\u003eSupplied with O-rings for proper service replacement.\u003c\/li\u003e\n\u003cli\u003eDesigned for compatible ZF marine gearbox oil-filtration applications.\u003c\/li\u003e\n\u003cli\u003eCommonly referenced for ZF 45, ZF 63, ZF 68, ZF 80, and ZF 85 transmission families.\u003c\/li\u003e\n\u003cli\u003eHelps protect marine transmission internals from oil contamination and wear.\u003c\/li\u003e\n\u003cli\u003eFilter housing may also be identified with \u003cstrong\u003e3312301037\u003c\/strong\u003e stamped on it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eEngine Compatibility\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis filter kit is used on compatible ZF Hurth marine transmissions, including many \u003cstrong\u003eZF 45A \/ IV, ZF 63 \/ 63A \/ 63IV, ZF 68A \/ IV, ZF 80A \/ IV, and ZF 85A \/ IV\u003c\/strong\u003e applications.

ZF service references commonly call for filter replacement after the first service interval and then at regular annual or hour-based service intervals.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eDrain or control fluid before removing the filter cover, then replace the filter and O-rings together. Lightly lubricate new O-rings with clean transmission fluid before installation, seat the filter correctly, and refill only with the fluid type specified for the exact gearbox model. After service, run the transmission, check for leaks, confirm proper fluid level according to the ZF procedure, and recheck after the transmission reaches operating temperature.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e3312199031\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e3312 199 031\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e3312.199.031\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e3312301037\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e3312301007\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHurth 463772\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eZF 978.26.610.01\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCrusader RP077011\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eIndmar 905005\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMercury 463772\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePleasurecraft Marine \/ PCM RP077011\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eVolvo Penta 3582069\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDriveForce 107691 \/ 107692\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe important check with this filter is the transmission model tag, not just the engine brand.
