Guys I have a few questions.i have search everywhere I can and the information that I am needing is how to remove the varidrive pulley and use a double clutch pulley system but I know the transaxle has to be raise in order for the belt to line up right and here the pic of my vari drive pulley. But I'd like have clutch system middle way not so close to the engine pulley so I could swap the engine pulley for more speed The 1st of the double clutch system is what I wanting to change the vari drive pulley out to of a different clutch system

The VariDrive Pulley itself has a snap ring on top holding it but if you're ditching it you may as well just unbolt the whole assembly AFTER you remove the springs and be careful because they are VERY strong springs!
You're right you need to raise it, some 1.5"x1.5" or 2"x2" thick walled tubing would work great and be strong!
What trans are you going to be running and how fast you want to go? Need to figure out pulleys in a hurry! Lol
@Brianator I want to run the MST 206 but I'd like to git up to at least 30 to 35 if I could or faster cause someday I want to enter my tractor in redzzo2 ttc challenge

I have a MST203 (3 speed) that I'm building to hopefully run 35mph, based on a racing mower calculator that no longer exists (of course) I'll be running a 6.5" pulley on the engine and a 4.5" on the trans to get there BUT that's based on MY final drive ratio of the trans, tire size and 3800rpms. I know half size pulleys aren't common but the ratio is almost the same with a 6"/4" combination.
I can only assume your 206 has the same final drive ratio as my 203 but I need you to check and it's really easy! Float the trans so you can spin the pulley by hand without having to chase it around the garage and make sure it's in 6th gear. I like to run a piece of masking tape from the center of the pulley to the outside of the tire to get a good strait line then rip off the tape between them. Then all you have to do is count how many times you have to spin the pulley until the mark on the tire is back to where you started. What I can't remember is if I had to hold the other tire from spinning to get and accurate count or not? On my 203 it was 6.8 turns making it a 6.8:1 ratio.
@Brianator thanks man I will check that out for u an let u know tomorrow morning as I didn't on the motor this morning.and the 6" to 4" if that can git me 35 id be happy with that and if I could git more speed that would be a plus cause I'm want something that is unbeatable and and that will hold to redzzo2 ttc competition
