CYLINDER SQUISH BAND CLEARANCE CHECK

A proper squish clearance can give your motor 10% more power. Most aftermarket cylinder kits are not made to this close tolerance of 0.6-0.8mm proper piston clearance. We check the squish band clearance and usually have to close the gap from .18 -.13mm down to .8mm gap for proper squish band function to work properly.

DIO MONSTER RACING PISTON PROBLEMS
54MM piston is too tall and will hit crankshaft. The skirts must be shaved to supply clearance for full piston/crank rotation.





OPENING THE INTAKE PORTS BY 10%
I am enlarging the aluminum crankase intake ports by 10% to see if it will increase performance at FULL POWER.





DIO 54mm Piston Clearance TIPS
Small aluminum corners have been removed and piston has full un-opposed travel throughout its 360 degree range. Cylinder deck height will me measured and fitted next.





(3)- Mating the 54mm cylinder to Stroker Crank
This is the tricky part of compressing both rings while trying to manouver a 4 kilo iron cylinder above them. It does not help with my slightly stiff, 50 year old hands. It should be a snap for you young guys. RH

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
