Beschrijving
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
How should the maximum working load be considered during installation?
Mount only in applications where the load does not exceed the product’s Maximum Working Load, and anchor to structures equal or greater than that load.
How often should long-term maintenance be performed?
Overhaul and clean at least twice a year. Frequency may increase after a heavy air regatta or passage, or before long-term storage.
What are the disassembly guidelines for inspection and maintenance?
Refer to product drawings or consult Harken custom engineering to understand how to disassemble, inspect, and clean all components.
When should roller bearings be replaced during maintenance?
Roller bearings should be replaced if their surfaces are rough, scored, or have flat spots.
What safety warnings should be observed during installation or use?
Strictly follow all instructions to avoid hazards. Ensure all people and objects are clear of moving components before use.
Who should install or service this V block?
Installation, disassembling, and reassembling must be performed by expert personnel with appropriate training.
How should the block be cleaned for short-term maintenance?
Frequently flush with fresh water, use mild detergent solution, and spin the sheave to distribute and remove debris.
How often is long-term maintenance recommended for this block?
Overhaul and clean at least twice a year and keep a log to determine your specific schedule.
What tools are needed to disassemble the V Block for maintenance?
For V Block maintenance, you need a metric hex key, soapy water solution, solvent to clean grease, and 222 Purple Loctite adhesive.
What should be done if parts turn roughly or make grinding sounds?
Perform long-term maintenance immediately if the sheave turns roughly or there is a grinding sound, especially metal on metal.
What should be used to seal mounting holes against water?
Choose a sealant for fastener holes that effectively prevents water ingress during mounting.
What materials considerations are there for mounting hardware?
Carefully choose fasteners made from A4 (316) stainless steel and isolate dissimilar metals to prevent galvanic corrosion when mounting.
What are key considerations for mounting hardware to avoid corrosion?
Use Tef-Gel between dissimilar metals or fasteners and carefully choose fastener materials to avoid galvanic corrosion.
How should fasteners be selected and installed?
Choose A4 (316) stainless steel fasteners, use large washers/backing plates, and secure with thread-locking solution as needed.
How can block drainage be checked or maintained?
Ensure that holes and drainage channels are unobstructed so water does not collect inside the assembly.
How should the block be mounted for proper load alignment?
Mount so loads align correctly with fasteners and padeyes; incorrect alignment can reduce strength or cause failure.
What is required for short-term inspection and cleaning?
Frequently flush with fresh water and clean with mild detergent. Inspect all fasteners and parts, tighten and replace as directed.
What caution is required when handling the bearing cage during disassembly?
Do not force the split bearing cage during disassembly or it can break. Use the cutout and split to disassemble and reassemble the sheave and bearing.
What actions should be taken if corrosion develops around fasteners?
Remove fasteners, inspect, and if needed remount hardware, carefully isolating with anti-corrosion compound; replace if corrosion persists.
Does the V Block use sideload balls in its bearing design?
No, V-Blocks do not use sideload balls, so there is no need to catch balls during disassembly.
What should be avoided when greasing or lubricating the block?
Do not grease product unless specified. Using grease can cause bearings to skid instead of roll, causing wear. Follow manual instructions for lubrication.
What should be done if the sheave is turning roughly or there are grinding sounds?
Overhaul the block immediately if parts are turning or traveling roughly, or if there is a grinding or metal-on-metal sound.
Should grease be used on V Block bearings?
Do not grease bearings unless specified; improper greasing can cause wear due to skidding instead of rolling.
What should be done before long-term storage?
Perform long-term cleaning, overhaul the block, and store in a dry location without saltwater inside.
What should be inspected for signs of operational problems?
Check for increased friction, scraping, or metal sounds. Do not use if these occur until the cause is determined.
