Conrod Bolts - ARP 2000 L19 Catcams NM088 F1 bolts.



ARP 2000 Rod Bolts are a definite upgrade from 8740 Rod Bolts. ARP 2000 Rod Bolts are a superior choice for any person planning on pushing his/her to its limits. Designed from an exclusive hybrid-alloy to assure superior strength and far better fatigue properties. Although 8740 and 2000's share some similar qualities and characteristics, ARP 2000's are capable of clamp loads in the 215,000 to 220,000 psi range. In this strength level, stress corrosion and hydrogen embrittlement are typically not a problem, providing care and the proper torque is applied during assembly.

L19 bolts
L19: This is a premium steel that is processed to deliver superior strength and fatigue properties. L19 is a very high strength material compared to 8740 and ARP2000 and is capable of delivering clamp loads in the 230,000-260,000 psi range. It is primarily used in short track and drag racing applications where inertia loads exceed the clamping capability of ARP2000. Like most high strength, quench and temper steels – L19 requires special care during manufacturing to avoid hydrogen embrittlement. This material is easily contaminated and subject to stress corrosion. It must be kept well-oiled and not exposed to moisture.

There are three methods that are commonly used to tighten rod bolts: using a torque wrench, measuring the amount of stretch and the torque & angle method. It is important to note that a fastener is like a very stiff spring and it must be stretched a specific amount. The material’s ability to “rebound” like a spring is what provides the clamping force to keep the rod bolted together. If you do not stretch the bolt enough, there may not be enough clamp load to keep the rod cap in place which could result in broken bolts or spun bearings. On the other hand, if you stretch the bolt too much, you can exceed the yield strength of the fastener which will weaken it and cause it to fail. Either of these two conditions can result in catastrophic damage to your engine. Always follow the manufacturers instructions to prevent damage to your engine.

Using The Stretch Method To Tighten Rod Bolts – Measuring bolt stretch is the most accurate method for tightening rod bolts and insures the correct pre-load. Simply measure the free length of the bolt before tightening, lube the bolt threads and rod spotface. Install the bolt into the rod and tighten until the bolt is stretched the proper amount. K1 Technologies offers an economical bolt stretch gage for this purpose.

Using The Torque And Angle Method To Tighten Rod Bolts – Do not confuse this with the “Torque to Yield” method. Torque to Yield stretches the bolt to a point where it will no longer return to the original length when loosened and requires the bolt to be replaced after each use. When using the Torque and Angle method, you lube the bolt threads and rod spotface, tighten the bolt to a low torque value as prescribed on the instruction sheet then, using an angle gage, turn the bolt a prescribed number of degrees to properly stretch the bolt. This method uses the highly accurate pitch of the bolt thread to control the amount of stretch.

Using The Torque Method To Tighten Rod Bolts – Torque does not measure clamp load and only measures the amount of friction that must be overcome to turn the bolt. The friction of the mating surfaces of the threads, rod spotface and bolt flange change with each tightening. When you consider the fact that different amounts and different types of lubes also change the friction, using the torque method is like trying to hit a moving target that you cannot see. K1 Technologies does not recommend the use of or provide torque values for tightening bolts.

evo ga prijevod  radi malo bolje nego google 

Postoje tri metode koje se obično koriste za stezanje povezujućih vijaka (budući da ne znam o čemu je riječ pretpostavljam da vrijedi za sve vijke pomoću kojih se spaja ili povezujei):
korištenje moment ključa, mjerenje količine zatezanja, momenta i kut metoda. Važno je napomenuti da je zatezač-vijak poput vrlo krute opruga koji mora biti pritegnut određenom silom. Materijal koji ima sposobnost "odskakati-odbijati se" poput opruge je ono što daje povezujuću silu i drži vvezu na okupu.
Ako se postigne dovoljno rastezanje vijka, neće biti ostvarena zadovljavajuća veza koja bi pridržala glavu vijka na svome mjesu, što može rezultirati pucanjem istoga ili povetujućih ležajeva. S druge strane, ako se vijak pretegne, možete se prekoračiti preko njegove snage prinosa što će ga ukonačnici oslabiti i dovesti do zakazivanja. Bilo koja od te dvije situacije mogu dovesti do katastrofalne štete na motoru, stoga je uvijek potrebno slijediti upute proizvođača kako bi se spriječilo oštećenje na motoru.

Korištenje metode: istezanja pritegnutih vijaka – mjerenje rastezanja-istezanja vijka je najpouzdanija metoda za zatezanje koja osigurava ispravno pre-opterećenje. Dovoljno je izmjeriti slobodnu duljinu vijka prije pritezanje, podmazati navoj vijka i vrh. Postaviti vijak i zategniti ga na odgovarajući iznos.
K1 Technologies nudi ekonomičan pritezač vijaka za ovu svrhu.


Korištenje moment metode i kuta pritezanja vijaka - Nemojte brkati
ovo sa "pritezanjem do popuštanja" metodom. Pritegnite vijak do točke do koje se on više ne vraća na originalnu dužinu prilikom otpuštanja istog te potrebe kada se vijak mora zamijeniti nakon svake upotrebe.. Prilikom korištenja metode momenta i kuta, potrebno je podmazati navoj i vrh vijka, pritegnuti isti na mali moment kako je to proisano u uputama, zatim koristiti napravu za kut i okrenuti za broj stupnjeva dan u uputi kako bi se vijak izdužio. Ova metoda koristi visoku točnost koraka navoja vijka kako bi se odrediča količina istezanja.

Korištenje Moment metode za pritezanje vijaka - moment ne mjeri učvršćeno opterećenje nego samo količinu trenja koje se mora prevladari kako bi se vijak okrenuo.
Trenja dodirne površine navoja, dodirne točke i samoga vijka mijenja se sa svakim zatezanja. Kada li uzeti u obzir činjenicu da je različitim količinama i različite vrste maziva također mijenjaju trenje, korištenje moment metode je poput gađanja okretne mete zavezanih očiju. K1 Technologies ne preporuča korištenje niti nudi aparaturu za istu za pritezanje vijaka .
