ARMA Super Modified Twin for 2010

I dont think it would hurt to try...thats advancements and how racing evolves. a cog belt is somethin that i wondered about when we put a vaccuum pump on our pullin truck with the gilmer drive set up. just not sure where to begin!! and that route could be quite costly

[jerb]

i think a cog belt would be the bomb......im sure it would work really well.....but not cheap, i gonna try the sepentine drive mostly cause i have the parts laying around, and the only thing im out if it doesnt work is the cost of a belt and time.....i still think it be way better than the belts we run now, just my opinion!

[Burwell555]

a feller would only think the serpentine would do well...like i said i wouldnt think twice about tryin it. i am one of them hillbillies with way more time than money

I like the looks of your mower, Jerb. It still looks like a mower! And I agree about the serpentine belt. If you use one about an inch or more wide. They are WAY stronger than a v-belt and they run a lot cooler, because they flex so much easier. That's what destroys v-belts (the heat the belt makes from being hard to flex)  I think its an excellent idea and as long as you can make your own pulleys it shouldn't be any more expensive. But I think pulley alignment is a lot more critical for a serpentine belt to last.

You would have to make the mounts strong so you could get the right tension on the belt.

You would have to make the mounts strong so you could get the right tension on the belt. 

Maybe just use an automotive tensioner?

[Burwell555]

i would imagine so..they are stout though

well got the shaft made up to extend out from the ragb, i used 7/8'' hardened shaft....cant wait to mill the keyway in it... , also got the outside bearing put on, there will be another bearing on the other side of the sprocket, but the store only had one...


 sorry for not so good photos, keep forgetting the camera so phone has to do the job...

[PitGuy]

If it is only cased hardened  ( first .025 )   take light passes till your through the case   Shouldn't be a big problem

i decided i didnt like how this turned out, i was too tired and in a hurry so with some sleep and some time this evening my outboard bearings are gonna get redone....i want to try and keep the ragb and outboard bearings as solid as can be...to prolong the life of the shaft and the ragb....pictures later tonight

[jerb]

well i got it redone much more to my liking, everything is 1/4'' material, this puppy isnt gonna move....the step through chassis are pretty light to begin with so weight is not really an issue, especially if you have the horsepower.....it might be an intek...but it gonna have the hosspower..


still not done, there will be another bearing on the other side of sprocket....as soon as somebody in town has the bearing and flanges...

man tim i wish i had the shop machinery you do... i could build sooo much lol...

[jerb]
