The Harken 32.2 Two Speed Winch is a robust mechanical device designed for marine applications, specifically for handling lines on sailboats. Its primary function is to provide mechanical advantage, allowing users to trim sails, hoist halyards, or perform other line-handling tasks with less effort. The "two-speed" designation indicates that the winch offers two different gear ratios, enabling users to choose between faster line retrieval (lower mechanical advantage) and greater power (higher mechanical advantage) as needed. This versatility is crucial for efficient sail trim and control in varying wind conditions.
Technical Specifications and Parts:
The winch is composed of numerous precisely engineered parts, as detailed in the provided parts list and exploded view diagram. Key components include:
- Drum (927216 Aluminum Drum / 928534 Bronze Drum): This is the cylindrical part around which the line is wound. The availability of both aluminum and bronze options suggests choices for weight, strength, and corrosion resistance, with bronze typically being heavier and more durable, while aluminum is lighter.
- Center Stem (27215) and Spindle (27218): These form the central axis of the winch, supporting the drum and internal gearing.
- Gearing System: The two-speed functionality is achieved through a complex arrangement of gears, including:
- Ratchet Gear (27219): Essential for the one-way rotation mechanism, preventing the line from slipping back.
- Gear Shaft (27222): Connects various gears within the system.
- Pawl Gear (27560): Works in conjunction with pawls to allow incremental rotation.
- Pawls (008) and Pawl Springs (038): These small but critical components engage with the ratchet gear to prevent backward rotation of the drum, holding the line under tension. The springs ensure the pawls remain engaged.
- Bearings (703192, 726073): Multiple bearings are used throughout the winch to reduce friction and ensure smooth operation of rotating parts, contributing to efficiency and longevity.
- Washers (27791 Plastic Washer, 27908 Washer): These are used to provide spacing, reduce friction, and distribute loads between components.
- Cover Plate (27909) and Ratchet Head (30608): These components enclose and protect the internal mechanisms, while the ratchet head provides the interface for the winch handle.
- Top Screw (6143): Secures the top of the winch assembly.
- Red Line Ring (28168): A visual indicator or decorative element.
The design emphasizes modularity, allowing for individual component replacement, which is a significant advantage for maintenance and repair.
Usage Features:
The Harken 32.2 Winch is designed for straightforward operation and integration into a sailboat's deck.
- Installation:
- Requires a flat mounting surface to ensure proper alignment and load distribution.
- Crucially, the sheet entry angle must be at least 8 degrees to ensure the line feeds correctly onto the drum, preventing overrides or premature wear. This is a critical design consideration for optimal performance.
- Mounting involves drilling holes and securing the winch with five 1/4" (6 mm) flathead machine screws.
- Bedding compound is applied to create a watertight seal and prevent corrosion between the winch base and the deck.
- Drain holes in the base must be kept clear to prevent water accumulation.
- Two-Speed Operation: While not explicitly detailed in the usage section, the two-speed mechanism typically involves rotating the winch handle in one direction for one speed and in the opposite direction (or engaging a different gear with a specific action) for the other speed. This allows for quick line retrieval in light loads and powerful trimming under heavy loads.
Maintenance Features:
Regular maintenance is paramount for the longevity and reliable operation of the Harken 32.2 Winch. The manual outlines a clear maintenance schedule: "Service winch before the sailing season begins and once during."
- Opening the Winch: The process is simple, involving removing the top screw and lifting off the drum.
- Cleaning:
- All parts should be cleaned with rags and solvent to remove old grease, salt, and debris. This is a fundamental step to prevent corrosion and ensure smooth operation.
- The manual explicitly states, "Clean all parts with solvent."
- Lubrication:
- Moving parts, particularly gears, should be lightly lubricated with grease. The manual advises, "Use a brush to spread a light, even coat of grease." This reduces friction and wear.
- Pawls and springs require light lubrication with oil, as grease can sometimes hinder their quick engagement. "Lubricate pawls using oil" and "Use oil for lubrication" are specific instructions.
- Pawl Servicing: This is a critical maintenance task, as pawls are central to the winch's ratcheting function.
- Pawls and springs should be removed, cleaned, and inspected for wear. Worn pawls can lead to winch slippage.
- The correct orientation of the pawl spring is emphasized: "Place spring against pawl with straight leg against pawl." Incorrect installation, such as mounting the ratchet gear backward, will cause the winch to slip, as illustrated in the "Incorrect" image.
- A small knife can be used to free captive springs during disassembly.
- Inspection: During cleaning and lubrication, all components should be checked for wear, corrosion, or damage. Bearings, in particular, should be inspected for smooth rotation.
- Reassembly: After cleaning and lubrication, the winch is reassembled, ensuring all parts are correctly positioned.
Suggested Service Kits:
Harken provides specific service kits to facilitate maintenance:
- BK4512: Contains 10 pawls (008) and 10 pawl springs (038). This kit highlights the importance of these small, wear-prone components and ensures users have replacements readily available.
- BK4513: Contains 100 ml of grease. This confirms that grease is a necessary consumable for regular maintenance.
The emphasis on using specific part numbers (e.g., "When ordering parts, please include a 'B' before each number (i.e. B008)") streamlines the ordering process and ensures correct parts are supplied.
In summary, the Harken 32.2 Two Speed Winch is a well-designed, maintainable piece of marine equipment. Its two-speed capability offers operational flexibility, while the detailed parts list and clear maintenance instructions empower users to ensure its long-term performance and safety on the water. Regular cleaning, lubrication, and inspection of critical components like pawls are key to preventing failures and extending the winch's lifespan.
