Yerfdog 3203 drive set up

[Mr.Pedroza]

I put a predator 212 on this kart and then bought a tav 2 replacement kit with and assembly mounting plate .. But which set up is preferable the assembly mounting plate or the original jackshaft set up ?

 

[firemanjim]

Since it came with the plate, I'd use it. The jackshaft set up might put the centers at a different length than the belt it came with, and might end up having to buy a different one. The plate is the weakest link to that tav,in my opinion, but you're better off running it. It's gonna make installation easier too, since you already have everything you need......

 

[Mr.Pedroza]

Thanks but I've used the jackshaft set up for a short time with a brand new jackshaft and bearings but after I've removed the jackshaft for some upgrades and I've noticed some intense wears where the bearings are which as a matter of fact was the exactly where the old jackshaft had so much wear that we couldn't run the kart and had to buy a new shaft .

 

[Mr.Pedroza]

Little more help ?

[Mr.Pedroza]

This one is the new shaft .. It is slightly rusted but hopefully you can see the wear marks

 

[Mr.Pedroza]

This is the old broken shaft ... Hopefully you can see where the old wearing and new wearing matches

 

[Mr.Pedroza]

Any other opinions

The one that causes wear on the shaft is the one in the link and the one I'm wondering if it's a good install part is the picture

 

[firemanjim]

If you have it, I'd run the one in the pic......
In my opinion, the other type needs some reinforcement, while still new, to endure a decent thrashing on a weekend kart. The sides start to flex outward from over tightening the mounting bolts. This leads to improper angles, eventually causing premature wear..... Sound familiar?

 

[Mr.Pedroza]

Ahh yes sounds very familiar ... Thanks from the advice I'll be sure to get everything on it right after I install the new axle assembly
