Harken 1.5T Carbon Loop V Block

Yes, only users with appropriate training should specify, install, or maintain this product to avoid damage or injury.

Use fasteners sized, typed, and in quantities as dictated by the product design, choosing materials that meet or exceed the maximum working load. For any mounting that involves different metals, ensure isolation to prevent corrosion.

It's crucial to ensure that mounting structures and anchors are at least equal to or greater than the product’s maximum working load and to follow industry best practices for rigging and load alignment.

When mounting to dissimilar metals (like aluminum or carbon), use isolation compounds such as Tef-Gel or Duralac to prevent galvanic corrosion. Regularly inspect for corrosion near fasteners.

Yes, anti-corrosion isolation (such as Tef-Gel or Duralac) should be used when mounting to prevent galvanic corrosion between dissimilar metals or carbon surfaces.

You need a metric hex key, soapy water solution, solvent, and purple Loctite adhesive for long-term maintenance of V Blocks.

Ensure all objects and people are clear of moving parts. Strictly follow all provided instructions to avoid hazards and injury. Only trained personnel should install and maintain the product.

You will need a metric hex key, soapy water solution, solvent to clean grease, Harken winch grease, and 222 Purple Loctite adhesive.

Overhaul and clean the block at least twice a year and after prolonged or heavy use, or before long-term storage. Immediate attention is needed if operation is rough or noisy.

Store your block in a dry location after performing long-term maintenance. Avoid leaving saltwater on internal components, as this shortens service life.

Always ensure all people and objects are clear of moving parts before operation. Lack of proper maintenance or incorrect procedures can result in injury or equipment failure.

Installation, disassembling and reassembling should only be done by expert personnel with appropriate training to avoid damage or injury.

Replace roller bearings if their surfaces are rough, scored, or have flat spots detected during inspection.

Inspect all aluminum parts for wear or corrosion and replace as necessary during maintenance.

Inspect all components for signs of wear or weakness, ensure fasteners are secure, and check that drainage channels are unobstructed.

Mount and align blocks to ensure load is directly aligned with the intended direction and structure. Misalignment can reduce capacity and increase wear.

Replace lashings and loops only with Harken supplied or specified parts to maintain the proper strength and reliability.

Exposure to teak cleaners or caustic solutions can discolor the part and this is not covered by the warranty.

Do not use the block until the cause is determined and repaired. Immediate overhaul and component inspection is required.

No, V Blocks do not use sideload balls, so there is no need to catch any during disassembly.

Lubrication is specified only for certain areas; if not indicated, simply clean the product. Greasing parts not specified for lubrication can cause bearing skidding and wear.

Use Harken winch grease for bearings and 222 Purple Loctite adhesive to secure fasteners when reassembling V Blocks.

Do not force the bearing cage during disassembly due to the split cage and cutout design, as it may break.

The bearing set uses a cutout in the inner race and a split cage; utilize these features for correct disassembly and reassembly.

Do not grease the product unless specified; improper greasing can cause bearings to skid instead of roll, causing wear.
