Description
Overview
Sideplates are constructed of hardcoat-anodized 6061-T6 aluminum for strength and corrosion resistance. The ultralight composite bearing system (ULC) rides on a heat-treated stainless steel inner race to handle extremely high loads.

FAQs
What safety precautions should be taken during installation?
Strictly follow all instructions, ensure all people and objects are clear of moving parts, and do not use without being trained or expert. Verify installations meet maximum working load requirements.
Is a sealant required during installation?
A sealant that prevents water ingress should be used in fastener holes during installation.
What is the guidance for choosing mounting fasteners?
Use A4 (316) stainless steel fasteners, large washers or backing plates, and lock washers or locknuts to achieve rated loads. Installer must ensure the fasteners are suitable for the expected loads and application.
What are key considerations for mounting to maintain rated load?
Mount so loads do not exceed Maximum Working Load, and anchors, structures, and fasteners used must meet or exceed this rating.
When should long-term maintenance be performed?
Conduct long-term maintenance after prolonged use, before storage, or if the sheave sounds rough or grinds.
What environmental exposure is the block designed to handle?
The block is designed for use in a marine saltwater environment, provided regular maintenance is followed.
What tools and supplies are suggested for long-term maintenance of megayacht blocks?
A pin spanner wrench, soapy water, Tef-Gel lubricant, and blue Loctite adhesive are recommended.
What should be checked regarding drainage during maintenance?
Ensure holes and drainage channels are not obstructed so water does not collect.
Should stray voltage be considered during installation?
Yes; control stray voltage aboard to reduce corrosion risks, consulting a marine metallurgical electronic corrosion expert if needed.
How should fasteners be chosen for mounting this block?
Carefully choose fasteners made from A4 (316) stainless steel, using large washers or backing plates and lock washers or locknuts, and ensure they meet or exceed the rated load.
What cleaning agents should be avoided?
Avoid exposure to teak cleaners or caustic solutions, which can discolor surfaces and are not covered under warranty.
What should be done if fasteners show loosening or corrosion during inspections?
Looseness or signs of wear/corrosion require tightening, replacement, and using blue Loctite adhesive as directed.
Is a torque specification provided for fasteners on custom blocks?
No specific torque values are given; use guidance from fastener suppliers based on diameter and conditions.
What should be checked during short-term inspection?
Inspect fasteners for looseness, signs of wear or corrosion. Check padeyes, shackles, lashings, and ensure all components operate smoothly without increased friction or scraping sounds.
Should original components be used for repairs?
Always replace components with original Harken equipment to ensure proper strength and fit.
How should fasteners be secured during assembly?
Use blue Loctite adhesive on fasteners as specified to secure them during assembly.
How often should overhauls be performed?
Overhauls should be done at least twice a year, after a heavy air regatta or passage, or before long-term storage.
Should lubricants be used on this block?
Do not grease unless specified. Using grease can cause bearings to skid instead of roll and should be avoided.
What should you do if you find wear or corrosion on ball bearings during inspection?
Replace any bearing balls if their surfaces are rough, scored, or have flat spots.
How should bearings be cleaned?
Flush bearing areas with soapy water while rotating the sheave, then rinse with fresh water to clean and check for smooth movement.
What should you do if the sheave turns roughly or makes noise?
Do not use the block. Overhaul immediately and determine the cause; replace parts as necessary before reuse.
What lubricant should be used on stainless/aluminum contact points?
Tef-Gel should be used where stainless steel and aluminum touch, but avoid getting it on bearings.
