Only ones i could find were the kind you pull tight with a pliers and fold back over itself and hammer these tabs to ghold it on. these didnt stay on either.
what clamps are you guys using? and where do you get them?

The shreddeing was due to heat the best I can gather. I have added a bunch of weight and slowed the rpms down to no more than 7800. Still running hot. Primary is 165 on the outer edges of the shieves and 135 towards the center. The secondary is 155 towards the edge and 135 towards the center. I am not sure where to take the temps at. I would assume I would look for the highest temp. I cannot figure out where the belt is slipping causing the heat, Anyone have a clue what I am missing? I have a Comet Pro-4, 4 arm clutch on the primary with 59.1 grams on each arm X 4 gives me a total weight of 236.4 grams. The secondary is a Team Inds. with 50/40F helix and a stock red spring. With the primary being the hottest I would think the main issue is with it. HELP!!!!! [smilie=dunno.gif]

http://www.minibuggy.net/forum/driveline/13793-crazy-out-box-reverse-idea.html
Tue, 07 Sep 2010 00:40:21 GMTHey I'm new around here, but have been reading posts for ages. I'm currently in the early stages of building a 4x4 motorcycle engine powered buggy. It will be built on a very tight budget, and a fnr gearbox is out of the question. The layout will be front engine, samurai transfer case, to samurai axle, single seater. I'm a crazy out of the box guy and I come up with something I really think would work. You can buy an electric winch replacement motor on ebay for about 85-100 bucks. They spin at 2100 rpm, have 4.5hp, and a 3/4 keyed output shaft. Now that's a common size, and you could put a go kart 5hp clutch on the output shaft of the winch motor. Put a chain on it, and gear it at about 3 to 1. I will be using a midget car driveshaft adapter so I was just going to bolt it up inline with the driveshaft. Pop the bike trans in neutral and engage the clutch and winch motor and backwards you go! Only problem I can think of is ground clearance on the larger gear on the driveshaft, otherwise everything is adding up in my head. Other MINOR issue is the winch motors aren't exactly light, about 20 pounds plus battery cable to make it work. So what do you think, or have I completely lost ya??? :D

I am thinking 630 chain but can't find sprockets with hubs i can attach to my setup. Would a industrial #60 or 60H be as good as a 630 (there are plenty of weldahub sprocket setups for 60 chain)? Another question is, could a 630chain be used on a 60 sprocket? Anyone using a taperlock sprocket? I plan on using a 16 tooth front and 18tooth rear or something close. Any input would be useful.

I...This is for the guys that have tuned your CVT with a turbo charger upgrade. I am having issues with rpm management throughout the shift range. I produce much more boost at higher rpms and is playing hell with me. I get low end tuned and over rev top end. Get top end closer and loose rpms on low end. Is this just a trade off, gotta loose a little here to gain it there? Or can I get the CVT tuned for the whole range? I make 12-13lbs at about 7600-7800 and about 8-10lbs low end. I just shredded my 3rd belt. I did testing at the house and everything looked pretty good. RPMs were good low and mid and over rev top end. Always checked the belt after a test run, never showed any signs of fatigue. I put the paddles on and hit the sand, figuring that the drag from the 2 would pull my rpms down. They did low end and slightly in mid but still over rev on top end. My 6th drag run I heard the belt ticking (like a time bomb) and shut it down. I have been told trying to tune with the boost verying is almost impossible. It is like tuning 2 different motors. What experience has everyone had with this issue. I am not the first to have this issue I am sure with all of the turbos out there. Any insight is greatly appreciated.

Sat, 21 Aug 2010 03:38:49 GMTThinking back to threads about the various ways to turn the axle including belts, chains, gears and driveshafts, I don't remember if this has been posted before but thought I'd share it.
I think this is used in European autocross cars and closely couples the engine to the axle. I don't recall anyone here using this and wonder why.
Seems as though the big gear could be reduced if some intermediate reduction was in the case, maybe with a reverse.

Thu, 19 Aug 2010 16:15:19 GMTI'm thinking about if this will work. Turn the motor sideways and couple it to a rear end out of a independant rear end car. Use a lovejoy coupling or similar. The idea comes from transworks rear diff w/ reverse but there would still be no reverse in my plan but maybe its a cost effective alternative. And no chain to break or wear out. I want ot get away from the chain if possible. Any input is appreciated.

The good:
It ran awesome. Clutching felt pretty damn good. It has way more low end than the ZX14 setup which makes the car feel faster. It feels significantly faster than my last Ecotec/CVT setup on the shotgun. I am not sure if that is attributed to the use of the 2.4vvt motor or what. I had it to 81mph before having to let off in one section so I have a feeling I am not gonna be losing to much of the top speed of the zx14 setup. Forgot how much faster you drive when you always have the right gear and put all the focus on steering and braking. I had second guessed moving away from the streetbike powerplant several times but the first drive in this thing confirmed that it was the right decision.
The bad:
After about 20-30 miles of driving, the belt blew up. I couldn't even find anything of the belt other than all the reinforcing strings wrapped around the drive clutch. I had done some crusing to get to the section of desert I like to go, then drove it somewhat hard through a rough section, then through a higher speed section. Toward the end of the higher speed section I lifted on the throttle for some dirtbike traffic and it seems like the belt came apart right then when I lifted. It may have started to come apart sooner but I am not sure. I definately heard the sound of destruction as I let off the throttle though. The drive clutch was stuck closed about halfway. I yanked all the strings out of the clutch because I though they were holding it open but they weren't. I pulled on the sheave a little bit and it slapped back open. Is this normal? Either way I barely had to pull on the sheave to get it to pop back open. Would that have anything to do with the belt blowing? It seems like the driven would pull it open with the belt when it would backshift. If I start the car without the belt on, the drive will close up a little bit, then when I shut the engine off it stays in the same spot until I pull on it a little bit and then it pops back, I don't remember the last CVT setup I had doing that. Is it bad?
The clutches are used off a Predator x-18 that I got for a really good deal. I wanted to get brand new stuff from ATVracing but I am hard up right now and I took a chance with this stuff to get the car going for now. The drive is a comet, not a 4pro but something different and cheaper looking. Looks like a mushroom like a cheaper go-kart clutch or a idustrial clutch. The driven is a Team rapid reaction. They are lined up just like they are on the x-18 and have the same C2C distance. Real beefy brace and bearing supports the outter ends of the clutches. They seem to work really well, the car can spin the 33" super diggers on pavement with ease. The response seemed really good.
I hope this is something wrong with the clutch or something and I didn't just trade in my chain problem for a belt problem.
I turn to you CVT experts for some help on this one. What should I be looking at to explain the premature belt failure?
