(Dub) 2 : You Wear More Than One Face

Face ID automatically adapts to changes in your appearance, such as wearing cosmetic makeup or growing facial hair. If there is a more significant change in your appearance, like shaving a full beard, Face ID confirms your identity by using your passcode before it updates your face data. Face ID is designed to work with hats, scarves, glasses, contact lenses, and many sunglasses. Furthermore, it's designed to work indoors, outdoors, and even in total darkness. With iOS 15.4 and iPhone 12 or later, Face ID even works with face masks.

University strongly recommends wearing a well-fitted, high-quality mask indoors (e.g., KN95, N95, KF94 and surgical masks) to reduce the potential for transmission. High-quality masks are available at no cost in several locations on each campus. University units can purchase high-quality facemasks from the Safe and Clean Storefront.

If you or your family member are at high risk for severe illness, wear a well-fitted facemask or respirator, such as an N95, KN95/KFN94 or surgical mask (in order of protection), in indoor spaces especially when the COVID-19 Community Level is medium or high. Respirators, including N95, KN95 and KF94, or a surgical mask provide greater protection than a cloth face covering. Note: UW employees that voluntarily wear respirators must receive this advisory information.

When the COVID-19 Community Level is low, we rely less on the use of face coverings as a layer of protection. When the community level increases we rely more on masks. We understand there are individuals who may not be comfortable with relaxing mask requirements. If this is the case for you, consider wearing a well-fitted facemask or respirator, such as an N95, KN95/KFN94 or surgical mask (in order of protection), in indoor spaces especially when the COVID-19 Community Level is medium or high. Respirators, including N95, KN95 and KF94, and surgical masks provide greater protection than a cloth face covering.

UW Medicine medical facility employees and visitors to UW Medicine medical facilities are required to wear a face covering and/or personal protective equipment (PPE) in accordance with UW Medicine policy.

A face covering can also be a mask that provides a higher level of protection than a cloth face covering, such as a medical procedure/surgical mask, or a respirator, such as a KF94, KN95, or N95 mask.

Individuals required to wear a face covering who have the following medical conditions or health risks may request an accommodation: a mental health condition, a developmental or cognitive condition, or a disability that prevents them from wearing a face covering. This includes, but is not limited to, persons with a medical condition for whom wearing a face covering could obstruct breathing, who are unconscious, incapacitated or otherwise unable to remove a face covering without assistance.

Begin with a polite verbal request for compliance to educate and persuade the individual to wear a face covering. University personnel should ask the individual to wear a mask or face covering, and have a supply of disposable facemasks to offer individuals who do not have one.

If, following a polite verbal request, the individual continues to decline to wear a face covering or facemask, personnel should notify the site manager to assist the customer with determining if accommodations, such as curbside pickup, can be made.

If the individual refuses to wear a face covering and does not indicate a medical condition or disability that prevents them from wearing a face covering, they should be politely informed that they are not permitted to enter and be asked to leave. Personnel should not attempt to physically block an individual or physically remove them from the space and should avoid confrontation but should not provide service. Law enforcement (e.g., University of Washington Police Department or local law enforcement agency) may be called for help as a last resort.

Both designs are fairly easy to fit and maintain \u2014 though bikes built with poor tolerances are prone to all sorts of problems, but we won\u2019t cover that here.\nThe tools required to service them have come down in price in recent years, but if you\u2019re looking to service them on the cheap, a hammer and sturdy block of wood can also do the trick.\nTo be totally clear, the processes involved for servicing press fit bottom brackets vary slightly from standard to standard, so the steps described here may not necessarily apply to your bike. If you\u2019re in any doubt, consult your local bike shop.\nTools required to service a BB30, BB86 or BB92 bottom bracket\nAllen keys up to 10\/12mm\nResin and rubber mallet\nGrease\nTorque wrench\nBudget option: Wood blocks and drifts, plus a hammer\nProfessional option: BB30 tool (e.g. Park Tool BBT-39) or Press-Fit cup drift (e.g. Park Tool BBT-90)\u00a0depending on bottom bracket type\nHeadset bearing press (e.g. Park Tool HHP-2)\n\n You can go either DIY or pro when servicing press fit bottom brackets BikeRadar\n1. Diagnose problems and how to remove BB30 bottom brackets\nTo spot problems with press-fit bottom brackets, drop the chain out of the way so that it doesn\u2019t rub against the chainrings.\nTurn the cranks to feel for roughness or play; feel for sideways play at the pedal end of the arm. As a (very) rough guide, more than about 1mm of play combined with roughness means it\u2019s time to replace the bearings.\nBegin by removing the left arm, which on SRAM\/Truvativ or FSA, and some others, will usually require a 10mm or 12mm Allen key and possibly an extension bar.\nThese can take a bit of hoofing to get off, so reinstall the chain onto the big ring to protect yourself in the event of a slip and work with the bike on the ground if necessary for better leverage.\nWith Shimano cranks, simply loosen the two 5mm pinch bolts, lift the safety latch and unscrew the retaining bolt.\n\n Removing cranks can take a bit of effort, so supporting the bike on the ground for extra leverage can help BikeRadar\n2. How to remove crank\nDrop your chain down off the inside ring; the whole right-side crank assembly might now simply push out. If not, give the protruding end of the spindle a decent tap with the rubber faced mallet.\u00a0Remove any dust caps, spacers or wavy washers and keep them in their correct order of position.\nHold onto the crank as it\u2019s being driven out to prevent it from dropping and getting damaged.\nWe\u2019ve found that some BB30 cranks might require a bit more force and a sharper blow for removal than BB86\/92, which should normally just slide out with \ufb01rm pressure.\n\n Note the order of any wavy washers you remove BikeRadar\n\n Gently tap the cranks with a rubber faced mallet to remove them BikeRadar\n3. How to remove BB30 bearings without special tools\nThere are two ways to remove BB30 and BB86\/92 bearings, and this step describes the budget option. If you\u2019ve invested in the proper tools described above, skip to step 4 (BB30) or 5 (BB86\/92).\nThe methods described here are essentially no different than those used for BMX bearing and one-piece crank removal. They seem somewhat primitive but they\u2019re an effective way of getting the job done.\nFirst, find a suitable drift. This can be a piece of narrow tubing or rod that \ufb01ts into the bearing aperture and allows you to strike the inner edge of the bearing cup for Shimano, or the inner race of a BB30 bearing. Whatever you choose, the edge of the drift should be square enough for a good purchase without slipping.\nAngle it \ufb01rst to one side, strike a sharp blow, then angle to the other side, strike a sharp blow, and repeat until the bearing has been driven out.\n\n Find a suitably sized drift and tap the bearings out BikeRadar\n4. Remove BB30 bearings with Park BBT-39\u00a0\nThese special tools still basically rely on brute force and impact to get the job done, but they differ from a piece of hardwood and mallet in that they offer a bit more control and precision over the process.\nTo use the Park Tool BBT-39, carefully angle it sideways in the bearing aperture to get the wide bit past the inner race as pictured on top. Insert it until it comes into contact and is squared up against the inside of the bearing, avoiding any circlips or internal frame ridges.\nNow give it a couple of good sharp whacks with a resin mallet to dislodge the bearing. Make sure you position and protect your frame in such a way that it won\u2019t fall over and damage vulnerable tubing or paint.\n\n Getting the tool into the bottom bracket shell can be a bit of a fiddle BikeRadar\n\n A few sharp thwacks should get the bearings moving BikeRadar\n5. How to remove BB86\/92 bearings with Park BBT-90\nPark Tool has a special tool for Shimano bearings, the BBT-90, which is a smaller version of its headset cup remover; it\u2019s just a slotted, splayed tube that you hit with a hammer.\u00a0A drift made out of a length of alloy tubing or rod, ideally between 15 and 20mm in diameter, will also do the same job.\nThe bottom picture shows the inner workings \u2014 there\u2019s really not much to it, other than possibly an internal ridge or circlip which you should be careful to avoid.\nNote the sequence of crank, axle and cup disassembly. Once installed, they work just like the threaded versions.\n\n A drift is also used to remove Shimano\u2019s press fit bottom brackets BikeRadar\n6. Inspection\nOnce removed, but before cleaning, spend some time giving the bearings and surfaces a good looking over to check for signs of wear or corrosion.\nNotice the rust marks by the pointer. Water will most definitely work its way in and settle in a pool if it has no way out.\nNow prepare to reassemble or install new bearings. Thoroughly clean the bottom bracket shell and make sure that the circlips are still correctly seated in their respective grooves, which are located just inboard about 1cm from the outer edges of the bottom bracket shell. There\u2019s no need to remove these.\n\n Inspect the bearings for any signs of unusual wear and try to diagnose the cause BikeRadar\n7. How to fit BB30 and BB86\/92 bearings without proper tools\nThere are two ways to reinstall BB30 and BB86\/92 bearings. This step describes the budget option. If you\u2019ve invested in the proper tools, skip to step 8.\nThe BB30 inner shell and crank spindle are usually aluminium, while the bearing races are steel, so copious amounts of grease can and should be used.\nIf possible, support the bottom bracket on a wooden block while knocking in the bearings. Although not the \u2018approved\u2019 method, if done carefully while keeping them parallel they\u2019ll go in just \ufb01ne.\u00a0The Park BBT-39 presses make life easier, but an old bearing or pipe drift will do it in a pinch, as long as it measures 41.5mm in diameter.\nEnsure that any wooden drift is properly \ufb02at, so that the impact is spread evenly through the entire surface of the bearing, and primarily the outer race \u2014 this will also avoid damaging the seal. Never press or drift in a new cartridge bearing by the inner race only.\n\n Make sure whatever piece of lumber you use has a solid, perfectly flat face BikeRadar\n8. How to fit BB30 and BB86\/92 bottom bracket with a headset press\nIf you\u2019re fortunate enough to have a proper headset press, such as the\u00a0Park Tool HHP-2, this can now be used in conjunction with the bearing press plates included in the BBT-39 toolset.\nPosition the headset press as pictured with the press plates up against the bearings and slowly tighten the press, ensuring it stays constantly aligned during the process. Press the bearings in until completely seated into the frame and bottomed out against the internal circlip stops.\u00a0But don\u2019t overdo it, as these can be damaged if forced.\nWith Shimano Press-Fit the process is identical, but more force will be needed. Tighten until you see grease oozing from between the edge of the cups and bottom bracket shell, ensuring there are no gaps left.\n\n While you can just use a sturdy block of wood, a proper bearing press is a wise investment for any home workshop BikeRadar\n9. Reinstall arms and tighten\nGenerously grease the spindle and insert the right side. Tap in with a mallet but protect the finish with a bit of tape.\nGrease the splined area of the spindle and reinstall the left crank arm, remembering the spacers, and tighten to spec.\n\n Protect the finish of the cranks with a piece of tape BikeRadar\n\n Torque up any pinch bolts to spec BikeRadar\nArticle last updated 15 January 2018","image":"@type":"ImageObject","url":"https:\/\/\/production\/volatile\/sites\/21\/2019\/03\/bb30-bb92-how-to-replace-service-1-1507550196740-xpy7tza68ewg-8c12ed7.jpg?quality=90&resize=768,574","width":768,"height":574,"headline":"How to service BB30 & BB86\/92 press-fit bottom brackets","author":["@type":"Person","name":"George Ramelkamp"],"publisher":"@type":"Organization","name":"BikeRadar","url":"https:\/\/","logo":"@type":"ImageObject","url":"https:\/\/\/production\/volatile\/sites\/21\/2019\/03\/cropped-White-Orange-da60b0b-04d8ff9.png?quality=90&resize=265,53","width":182,"height":60,"speakable":"@type":"SpeakableSpecification","xpath":["\/html\/head\/title","\/html\/head\/meta[@name='description']\/@content"],"url":"https:\/\/\/advice\/workshop\/how-to-service-bb30-bb86-92-press-fit-bottom-brackets\/","datePublished":"2018-01-15T11:50:00+00:00","dateModified":"2019-07-26T15:40:37+00:00"}] How to service BB30 & BB86/92 press-fit bottom brackets 10-step home maintenance guide 041b061a72
