Rodajul:
Atentie: Acesta este un subiect foarte controversat!

Aceasta metoda de a efectua rodajul este folosita de tot mai multi avand in vedere rata de succes foarte mare si defectiune putine!
Metoda explicata aici a fost incercata de sute de soferi, care confirma ca metoda aici expusa este un succes desi este in contradictoriu cu manualul de utilizare.
Aici puteti citi pagina originala!

Rezultatele sunt acelasi in toate cazurile, cresterea puterii a motorului pe toata plaja de turatii. Multi mecanici care au desfacut motoare au constatat ca starea pistonului si a camasii sunt cu mult mai bune decat daca este facut rodajul dupa Manualul producatorului.

Sigur ca sunt publicate si metode mai vechi despre cum se face rodajul corect, dar trebuie avut si in vedere ca motoarele sunt de ultima generatie si deaceia informatiile vechi nu mai sunt valabile.

Unul dintre motivele care au dus la aplicarea sistemului nou de Rodaj este ca honarea cilindrului se face cu pietre cu mult mai fine si matricea lasata pe suprafata cilindrului este mai fina decat prelucrarile de pe vremuri. Chiar si utilajele cu care se prelucreaza componentele din ziua de astazi sunt de obicei Utilaje performante CNC. Acest fapt duce si la temperaturi mai scazute in timpul rodajului in motoarele moderne.

Folosirea tehnicilor avansate de honuire si crearea suprafetelor mai fine duce automat la scaderea frictiuni si timpul de asezare a segmentilor.

Cu asta spuse....

Cum sa-ti faci rodajul corect pentru mai multa putere si mai putina uzura!
Cel mai important moment pentru un motor nou este rodajul!!
Indiferent cat de bine este asamblat un motor, puterea finala depinde de tine!!!

Urmatoarele exemple se refera la toate motoarele in 4 timpi, cu cilindrii din aluminiu, Nikasil sau cele composite cum sunt folosite de Yamaha.

Care este cea mai buna varianta pentru rodaj?

Raspuns scurt: dai tare!!!

KTM timing marks for Cams

Did you ever search the timing marks on a KTM which indicate the correct positition of the Cams in TDC? Well, here's the secret: Loook in the opposite side of the Timing chain for the two marks which have to be both visible when in correct position. If necessary turn you Cam until both marks are visible.

Had a Cam Chain tensioner failure ...

After riding uphill I stopped and laid my FR down. Starting it up again, a rattling sound... end of story. ...fact is the hydraulic Cam Chain tensioner or also called the Timing Chain tensioner of my Ktm Freeride 350 stopped its duty cycle causing the Cam to turn over one tooth. Luckily on tooth didn' t damage the Valves, so the got no hit from the cylinder and didn't bent or even break. That would a been a disaster. This is how the Original KTM hydraulic Cam Chain tensioner looks like: Normally oil pressure is even too High causing too much wear of the chain. Testing my hydraulic Cam Chain tensioner on a flat table, pressing it down it remained blocked. It should not happen after only 70 hours. Conclusion:  I will grab a new mechanic Cam Chain tensioner from Mito Racing and get rid of any trouble and noises coming from my engine. Adjusting the new Mito Racing Cam Chain tensioner is pretty simple. I have put a little HowTo and review here.

How to tension your Cam Chain using a mechanic Timing Chain tensioner

How to tension your Cam Chain using a mechanic Timing Chain tensioner... this one is from Mino-Racing This is the buddy from Mino-Racing which I mounted in my KTM four stroke. KTM uses from 2006 onwards a hydraulic Cam Chain Tensioner which gets faulty after only a few hours. I guess it is mandatory to change the original hydraulic timing chain tensioner with a mechanical one to avoid break downs in the middle of nowhere! In this short Video you can see all action it takes to tension your Cam Chain. You have to pre-tension it by hand first until the Cam Chain is firm and afterward give it another half to three quaters of a turn with the hex. After that you can fix the counter hex and be shure no problems will occur. Check your timing chain tension every 20 hours or with any valve clearance check!
