Description

SIERRA OMC Stringer Tilt Worm Gear Shaft – 18-2156

Sierra 18-2156 is the tilt worm-gear shaft used in pre-Cobra OMC stern-drive tilt assemblies. It is cataloged for OMC I/O applications from 1964 through 1986, excluding Cobra, and replaces OMC 980183 / 310613.

• Replacement shaft for the OMC Stringer mechanical tilt worm-gear mechanism.
• Cataloged for 1964-1986 OMC I/O applications excluding Cobra.
• Crosses to OMC 980183 and 310613.
• Also cross-references GLM 22040.
• Inspect worm gear, bushings and housing wear so a new shaft is not installed into damaged mating components.

For marine drive and engine service parts, fitment can vary by model, serial number, gear ratio, casting and prior service history. Compare the original OEM number and physical configuration before installation, and replace related seals, bearings, locking hardware or cable components when their condition requires it.
