Description

SIERRA Mercury / Force Gearcase Oil Seal – 18-2052

Sierra 18-2052 is a precision replacement radial oil seal for selected Mercury, Chrysler and Force lower-unit applications. Its 22.2 mm shaft size and 33.4 mm outside diameter make dimensional verification especially useful when servicing older gearcases or drives with superseded OEM numbers.

• Oil seal for marine gearcase and lower-unit service.
• Outside diameter: 1.314 in (33.4 mm).
• Shaft diameter: 0.875 in (22.2 mm).
• Seal width: 0.322 in (8.2 mm).
• Use the OEM number and measured seal cavity/shaft dimensions to confirm fit before installation.

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.
