Description
Overview
The V block delivers another breakthrough in Harken’s loop block series for Grand-Prix racers. Harken engineers have simplified the mechanics by combining the axial and thrust bearings into a single bearing set of V-shaped titanium rollers. The result is a strong, lightweight block that offers unmatched efficiency at high loads, while spinning freely at low loads for smooth easing in light air. Harken V blocks are standard with 3D-molded carbon sideplates, titanium sheave, and captive titanium roller bearings. V blocks are easy to disassemble for inspection and maintenance.

FAQs
Are there specific tools required for V Block long-term maintenance?
You should use a metric hex key, soapy water solution, and solvent for cleaning grease. Harken winch grease and 222 Purple Loctite® adhesive are also specified.
Should V Blocks be greased during maintenance?
Do not grease the product unless specified, as this can cause bearing skidding and wear. Only specific bearings may require grease—follow instructions closely.
What tools are required for long-term V Block inspection and maintenance?
A metric hex key, soapy water, solvent for grease, Harken winch grease, and 222 Purple Loctite adhesive are needed.
What are the loading requirements for installing the V Block?
Mount only where load does not exceed Maximum Working Load; structures and anchors must also meet or exceed this load rating.
Are there application or environmental limitations for V Blocks?
Harken custom products are designed for use in a marine saltwater environment provided regular maintenance is followed.
What should you inspect during short-term maintenance of V Blocks?
Inspect all components for wear, corrosion, or damage. Ensure free movement and check for unusual friction or noise. Replace weak or worn parts immediately.
What are the consequences of improper maintenance or operation?
Lack of adequate maintenance shortens product life; don't use if there is increased friction or a scraping sound—resolve issues before use.
How often should long-term maintenance be performed on the V Block?
Overhaul and clean at least twice a year or after heavy use, keeping a maintenance log as recommended.
What is the correct procedure for cleaning V Block bearings during maintenance?
Use soap and water to clean parts; rinse with fresh water. Avoid grease unless specified, and see manual for greasing instructions.
Should you use grease during maintenance of V Blocks?
Only use grease if specified; using grease in non-specified areas can cause bearing wear due to skidding.
How should V Block fasteners be secured after maintenance?
Secure fasteners using blue or purple Loctite adhesive, per tool and supply recommendations.
What is the consequence of not performing adequate V Block maintenance?
Lack of adequate maintenance will shorten the product's life. Always follow the recommended schedule.
What tools are needed for V Block long-term maintenance?
For long-term V Block maintenance, you need a metric hex key, soapy water solution, solvent to clean grease, Harken winch grease, and 222 Purple Loctite adhesive.
How often should long-term maintenance be performed on V Blocks?
Long-term maintenance should be performed after prolonged use, before long-term storage, or if the sheave is turning roughly or making grinding noises.
What is the guidance for using grease during maintenance?
Do not grease V Blocks unless specified in the instructions; improper use can cause bearings to skid rather than roll and lead to wear.
How should fasteners be secured after V Block maintenance?
Use blue (or 222 Purple) Loctite adhesive to secure fasteners after maintenance, ensuring threads are clean and residue-free first.
What precautions should be taken when mounting hardware to prevent corrosion?
Use Tef-Gel® between dissimilar metals, and ensure fastener holes are sealed to prevent water ingress. Inspect regularly for signs of corrosion.
Who is responsible for proper specification and mounting of the V Block?
The customer is responsible for specifying, mounting, and aligning the product to achieve its rated load capacity.
What safety warnings are associated with installing or using V Blocks?
Strictly follow all instructions to avoid hazards that may kill or injure. Make sure people and objects are clear of moving components.
Are there torque specification guidelines for assembling V Block fasteners?
Torque settings for most custom products are not available; consult fastener supplier guidelines based on diameter and lubrication.
If bearings or sheaves are damaged, what is the recommendation?
Replace any worn or damaged roller bearings, and return sheaves with worn bearings to Harken for service.
Can bearing cages be forced during disassembly?
Do not force the bearing cage during disassembly, as it can break. Use the cutout and split cage to separate as directed.
What should be done if the sheave turns roughly or makes noise?
Overhaul the V Block immediately if the sheave is turning roughly or there is grinding, especially metal-on-metal.
Can the bearing cage be forced during disassembly or assembly?
No, do not force the bearing cage or it can break. Use the cutout and split as indicated in the instructions.
When should V Block components be replaced?
Replace any worn or damaged components after inspection. Use only original Harken parts for replacement.
