Mugen MBX5 Prospec - Crankshaft type?

[HeartBreak]

I'm getting a mugen MBX5 Prospec coming up soon, and need to know what type of crank shaft on the engine that the clutch needs. Does it need a "pilot" shaft, a standard crankshaft, or a shortened one?

[vbgagnon]

the long one...i think its called a SG shaft. Most .21's or larger come with the "SG" shaft, so thats what you need.

SG crank is the norm on the buggies.

SG and pilot are the same thing. Also you can not run a pull start mill in a prospec! I learned the hard way when building my truggy.

Heh, no worries about the pullstart; goin all new on this car, including the starter box. It's getting an OS V-Spec.

If I am not mistaken I was told that a "pilot" shaft is an adapter to change a threaded shaft to work like a "SG" shaft.

That's primarily the reason I posted the thread - I wasn't too sure if the SG and pilot were the same thing, or what... Thanks everyone for clarifying the issue - when the MBX5 arrives, pics shall be posted.

yes the pilot shaft is an adapter......

oops, i read somewhere it was the same. Damn false forums. Make shure when you get the v-spec, to tear it down and whipe it down with baby whipes,j/k,lol.

LOL - I intend to dissect the engine and clean it out thoroughly with DA, inspecting for stripped holes in the crank case (had a megatech engine that came with a stripped backplate hole), and reassemble it as best as can be.
