Description

The CENTA CF-R 3227116003 is a highly flexible torsional coupling for marine drivetrain applications using ZF 285 / ZF 286 A/IV transmissions with an SAE 11.5 flywheel connection. The CF-R design uses rubber rollers loaded in compression to help reduce gear chatter, absorb torsional vibration, and provide smooth torque transfer between the engine and marine transmission. This coupling is built for heavy-duty service and is designed as a fail-safe, progressive-characteristic coupling for demanding marine driveline setups.

Transmission Compatibility

This coupling is associated with ZF 285 and ZF 286 A/IV marine transmission applications using an SAE 11.5 flywheel setup. It should be matched by the exact transmission model, flywheel housing, flywheel size, input arrangement, and existing coupling reference before ordering. Supporting product references also note that this specific SAE 11.5 CF-R coupling does not fit Caterpillar engine applications.

Serial Number Fitment Notice

Torsional coupling fitment depends on the exact engine model, transmission tag, flywheel housing, SAE size, spline/input configuration, and duty rating. Always confirm compatibility using the engine serial number, transmission ID plate, and existing coupling part number before ordering. Do not match by “SAE 11.5” alone.

When This Part Needs Replacement

Replace the coupling if there is visible rubber deterioration, cracking, loose or damaged components, worn splines, excessive gear chatter, vibration, clunking during engagement, or evidence of drivetrain shock damage. A worn torsional coupling can transfer harmful vibration into the transmission and driveline.

Installation Notes

Installation should follow the engine, transmission, and CENTA assembly procedure for the exact driveline. Inspect the flywheel, bell housing, transmission input shaft, mounting hardware, alignment, and surrounding drivetrain components before reassembly. Couplings should be selected and installed as engine-matched drivetrain components, not as universal gearbox accessories.

Parts Desk Insight

The key match here is the complete drivetrain combination: ZF 285 / 286 A-IV, SAE 11.5, and the existing coupling reference. A coupling can look correct but still be wrong if the flywheel, input, or engine application is different, so confirming the transmission tag and current coupling number is the safest way to avoid an expensive mismatch.
