I have a 1973 sierra trail boss, my question is as follows. Instead of the standard belt drive clutch system do you think it's feasible to convert to a direct chain drive system ???? By looking at the design of how everything works i'm thinking a chain drive would be ok sense the drive system to the transmission is a free spinning nutrual type set up.
Has anyone tried this before or does anyone have any comments on this.

ron diter, yes i think it's a great idea, but maybe not for this transmition, yours is among thoughs that are not to dificult to brake apart, best to ovoid the posability,
i would do it to a t-20 trany though as they are verry strong, (the older ones with oridganal lignings)
i can rev my 2 stroke up into 1000's of rpm's and engage the latereals to pop a wheely,
seams this is a good indicater of how strong this type of trany is,
my friend bob had a trail boss with an exploaded trany on one side, the cast iron gears and gear holder broke apart,

Ron,
The belt system, besides being having a clutch also works as a variable transmission which senses engine and vehicle speed and load and makes adjustments in ratios to suit. Going to a chain drive to me means picking a ratio and not being able to change it easily.
