Chain lube...

Any progress on this? I'm curious to see how the v belt works out.

Sadly no. Crops are ready to harvest now, so I'm busy working I'll see if I can get it done on a rainy day or something..

Rainey day so I went shopping I'll have to wait for another Rainey day to assemble

V-belts work!! I used one on my kart for a clutch system and they work, so you know they will definitely work for a fixed tension on them. Probably even better

Thanks We know V-belts work

What I'm doing is putting a V-belt on a torque converters final drive... I haven't seen any one on this forum do it yet so well see what happens...

Here's a picture. You see the chain.. well that's getting replaced with a belt

What I think anickode is curious to see is how much performance I lose to belt slippage. Torque converters produce lots of torque when starting off...

Yep, that's what I was getting at. Since unlike a chain, which has positive mechanical engagement, belts rely on friction. The 2 ways to get more friction are increased contact area ( bigger pulley) and more tension, which increases wear on parts and further decreases the efficiency. Since your small driver pulley size is limited by the maximum size of the axle pulley in order to maintain gear ratio, if slippage is an issue, your only option is to run the belt tighter, which causes increased wear on the belt and bearings.

Like I said above, I'm skeptical of the long-term performance, but interested to find out for sure. You just don't see v belts used as final drives on much of anything. Chain or cogbelt seem to be the preferred means.

MTNSledder, if you do have slippage issues, you can look into running a rub-on or aerosol belt dressing.

Belt dressing is kind of a double edged sword though... It helps the belt grab a little better, and conditions it to help it last longer, but it also makes dirt stick to it more, which will decrease belt life

Well Rainey day finally..... Tested it and have concluded that V-belts have no place on a TC final drive....... Took the hard way to find out but now I know........

What happened? Why didn't it work? I see no reason why it couldn't work.

Too much torque on too small a surface area I would wager.

Jackshaft pulley slips, engine revs, TAV climbs to a taller gear ratio, smokes the belt before it ever moves.

Well it work for a few miles... But once the belt started to slip and get hot it got glazed and when the belt gets glazed go kart don't move anywhere... Than you have to start walking a few miles with a go kart that doesn't move to get home..

Pros with it was it was really nice and quiet...

Cons with it Belts glaz up to fast and wasn't very fun to drive....

Well I'll just do what most normal people around here do and stick a Chian back on...

 

[anickode]

A cogged belt would be the ticket if you really don't want to use chain.

Or make a housing to protect the chain if dirt and debris is causing it to fail quickly.

 

[MTNSleder]

If I lived in the USA maybe I'd put a cogged belt on.. here in Canada it hard to find stuff like that...

 

[MTNSleder]

I also tried belt dressing like you suggested anickode it help but theirs simply to much HP for a v belt...

We'll sneak you one across the border or send it across the river by inflatable raft.......... TRY EBAY.........

...Would this be a retarded idea, if I some how fabricated a chain case for the chain so the chain is sealed from the dust and the chain take's a bath in oil all day IDK...

Not sure an oil bath is going to work...but the chain case sounds like a good idea actually.

As far as I can visualize it, the case is going to have openings for the engine PTO side and on the bottom end for the axle.
Even if it's just partially shielded, it'll do wonders for cleanliness.

The other possible causes for your catastrophic chain issues, that were never addressed, might be...YOU.
I mean you could have misalignment between your sprockets or craptacular sprocket quality, bent sprockets, mangled teeth (burrs) and what-not causing your chain to "chew" itself to death or fall off over and over.

 

[anickode]

Yeah oil bath not so good with a TAV plate setup. You'd likely wind up with oil on your belt.

Some good O ring chain and an improved chain guard would go a long way.

Also as Hellion mentioned, make sure your sprocket alignment is just right and your sprockets aren't worn down.

Well the sprocket is over 30 years old and sat out side for that time, and was fairly rusted with pitted teeth.. maybe I'll get a new one... I didn't think it mattered but maybe it dose..

So I guess maybe I'm the chain problem I'll buy new sprocket and go with some 40" chain instead of 41" chain... O-ring chain don't have enough Canadian tire dollars for that....

Yeah, in the purest sense of a chain guard I'm thinking along the lines of a simple straight-chain setup; engine sprocket to drive sprocket--which could work. You're correct though, it (and any oil) is not good in the vicinity of whirring belts and such...

I've never seen a chain guard for the bottom half of the drive sprocket on a go kart/buggy, but the bottom end is most vulnerable to mud, dirt and sand, not to mention whatever is kicked up by the front tires.

O-ring chains though...the cyclists swear by them.
