Cambio de pistón y cilindro de motor.
Visita mi BLOG: http://angelatedo-angelatedo.blogspot.com.es/ Hola a tod@s. Hace unos años que cambie el cilindro y el pistón del motor de mi motocultor. Fue el mismo día que le cambie las cuchillas, es decir que es día estreno "zapatos", y "corazón" Primero les comento, que estuvo tiempo parado ya estaba un poco cascado, lo preste a alguien, y uso gasolina con poca aceite, total que acabo por reventar. Los petardazos que sonaron fueron grandes, total que se reventó por algún sitio el pistón o émbolo y ya no hubo forma de que funcionara, pues parecía que iba a explotar....Al almacén y a comprar uno nuevo. Bien, primero decir que de mecánica de motores no tengo mucha idea. Pero manejo de herramientas, y desarmar y armar es lo mío. Me puse manos a la obra, y desarme el motocultor, depósito de gasolina, mangueras, etc. Luego el tubo de escape, tornillos, anclajes, bujía,.... Y por fin el motor que pieza a pieza fui desmontando. Varios trozos estaban dentro del cárter, otros en el cilindro. Tuve que vaciar todo limpiar a presión, volver a echar aceite, engrasar, y también limpiar la zona susceptible de entrada de polvo, barro, etc. No le hice una limpieza a fondo, pues el que tenga un motocultor sabe, que dura cinco minutos, pues el polvo y la tierra se adhieren rápidamente. Pero sí a la pieza concreta del motor. Este bloque una vez cerrado impide la entrada de polvo, tierra,... En el kit viene completo, sus arandelas, pistón con sus segmentos de cierre, rodamientos, juntas, cilindro,... Una vez visto cómo estaba ya lo pude volver a montar. Colocar las piezas cada una en su sitio, Y con esto aprendí mucho del funcionamiento de un motor, cigüeñal árbol de leva, biela, orificios de compresión, admisión, bujía, culata, cárter, porqué es de dos tiempos, lleva mezcla, es decir gasolina con un 5% de aceite,...... Y así todas las piezas, y lo más importante aprendí que no se debe dejar de echar aceite en su justa cantidad, que la gasolina en un motor parada no es buena durante mucho tiempo,... Bueno sabemos que el funcionamiento de un motor no se explica en cuatro líneas,... pero lo que he querido compartir es que a pesar de no tener mucha idea pude cambiar el "corazón a mi mulilla", que es la que me quita mucho trabajo. Muchas gracias y espero les guste el video. Saludos, Ángel





Piston making for a modeldiesel engine at home (MK-16 rebuild) Part 1
Hello again for a very interesting episode.In this clip I show you,how I make my pistons self. Its a part of the rebuild of my MK-16, aprox.1956. I use always old carengine camshafts.With that material( high grade castiron) I got good expirience in the past. I done a lot pistons so far, but in the begining,I lost a lot work,because the expirience was missing.The diesels got moore closer tolerances than a glow engines,because of the high compression. The old MK-16 was in very bad shape,impossibel ,to be a runner.The rear disc was worn out,the 2 bearings, very bad,even one broken....the prop collector was not from this engine (and broken also) and the most important thing,no compression at al. I buy a lot special tools,what makes it possibel,to do this work.But its stil a kind "on the edge" job. Its not easy to do it with this hobby equipment. In 2 evenings with each moore then 2,5 houers,It was finally done. ...But I make a mistake( also a lot in the text,ha,ha...sorry) ...I shoud first make the final size with the grinding as first step...and after that,drill the wrist pin hole. .Because the holes have a influence on the grinding pattern,its moore accurate to grind a closed surface. Because of that mistake,I got extra work,to get the piston lapped wel and sealing wel.Its now oke,but next time I must not forget it...save much time,and fare better result! I l also dont make the rings on the outer piston. The wal thicknes is less like the orginal piston.I wil risk a crack forming or even a broken part...so I deside not to take the risk.It run fine anyway without it. The MK-17 also dont have it anymoore...But I see this strange aplication also on my Russian K-16 engine from 1950 !..same factory I asume. ) I hope you like the visit in my smal workshop...enjoy part 2!

http://www.colinfurze.com THIS WAS DONE ON A SHIT BACKROAD THAT LEADS TO A FARM NO MOTORBIKES COME DOWN THIS ROAD UNLESS THEY WANT A SACK OF POTATOES BUT TRY PUTTING THEM ON YOUR R1 .The second part was filmed on a more used road but oil had all gone by then so stop worrying i ride a bike to you no. Amazing footage of a set of normal 4 cylinder car pistons moving at normal speed and more. As a petrol head i no this happens but to actually see the speed for real is just wicked. My favirite bit is when they look like there slowing down Poor old rover 200 Honors- #1 - Top Rated (Today) - Cars & Vehicles #1 - Top Favourited (Today) - Cars & Vehicles #1 - Most Discussed (Today) - Cars & Vehicles
