Sunluway Gimbal Bearing Puller & Installer Kit for Mercruiser/Bravo/Volvo – Alignment Plate & Threaded Puller

Sunluway's Gimbal Bearing Puller Remover, Bearing Installer & Engine Alignment Tools Set is a complete kit for removing, installing and aligning gimbal bearings on Mercruiser Alpha/Alpha 1/MR, Bravo, OMC Cobra and Volvo sterndrive systems.

This professional-grade set collects the specialty pieces needed to service sterndrive gimbal bearings and check engine alignment without guessing. The kit combines a threaded puller for extracting worn bearings, a driver for installing new bearings (used together with the alignment plate), and an alignment tool that helps position the engine and protect the coupler and gimbal during reassembly. Each tool is machined for durability and designed to work with common workshop hand tools.

How does the gimbal bearing puller remove a stuck bearing?

The puller uses a threaded central shaft that draws the bearing out as you tighten with a wrench. This creates controlled, straight withdrawal forces so the bearing comes free without hammering or damaging the housing.

• Threaded rod pulls bearing centrally to avoid cocking.
• Wrench-compatible end for simple manual operation.
• Sturdy construction to resist bending under load.
• Designed for sterndrive gimbal bearing sizes common to listed brands.

What do I need to install a new bearing using this set?

Installation requires the alignment plate (engine alignment tool) used as a stable guide and the bearing driver that presses the new bearing into place. The driver fits through a hole in the alignment plate so the bearing goes in square and to the correct depth.

• Alignment plate provides a flat, centered reference surface.
• Bearing driver transfers even force to the new bearing outer race.
• Some kit pieces require drilling a small mounting hole in the plate for driver fitment.
• Use common hand tools—no hydraulic press necessary for most installs.

How does the engine alignment tool protect my coupler and gimbal during service?

The alignment tool lets you set and check engine position relative to the sterndrive before final tightening, reducing misalignment forces that cause premature coupler and bearing wear. It also supplies mounting options so you can suspend or hold components during reassembly for safer, more precise alignment.

• Checks fore-aft and radial alignment to save coupler life.
• Includes eyebolt for hanging or positioning alignment plate.
• Use as a reference while torquing engine mounts and coupler fasteners.
• Helps ensure the new bearing seats squarely to reduce vibration risk.

Which boat drives and situations is this set compatible with?

The Sunluway kit is sized for common sterndrive models, including Mercruiser Alpha series, Alpha 1, MR, Bravo units, OMC Cobra drives and many Volvo setups. It’s intended for routine bearing replacement, preventive alignment checks, and repair jobs where access to a press is limited.

• Fits Mercruiser Alpha/Alpha 1/MR and Bravo models.
• Compatible with OMC Cobra and many Volvo sterndrive gimbal bearings.
• Useful in DIY, marine shop, and dockside repair scenarios.
• Reduces need for heavy equipment by enabling hand-tool service.

Who is this for: boat owners, marine technicians and do-it-yourself mechanics who work on sterndrives and need a reliable, workshop-friendly solution for gimbal bearing service and engine alignment. If you maintain Mercruiser, Bravo, OMC or Volvo sterndrives and want tools that reduce risk to the coupler and ensure correct bearing seating without a press, this set gives the core pieces to complete the job efficiently.
