Hey guys, awesome forum!
I'm having some trouble with a custom belt setup I'm running. See, I'm using a B&S 12.5HP vertical motor, connected to a Spicer transaxle, with an idler pulley setup as the clutch. I press the brake/clutch, the idler loosens and applies the transaxle's brake.
Well anyhow, the transaxle is a 6 speed, with a 12:1 ratio in 6th. On the motor I have a 3.75" pulley, and a 1.75" on the transaxle, they're all I had and I wanted some speed. Well with the tranny in 1st or 2nd, it pulls great, gobs of power, just slow. However, with the tranny in 3rd there's a lot of slippage in the belt going up hills, and 4th, 5th, and 6th gears are useless as they slip constantly unless someone pushes to get it started.
So, I'm racking my brain trying to figure out a way of correcting this. There's about 25lbs of tension on the belt right now, and I have no way of adding more. So, I've come up with two possible solutions and would like some input.
A; Get a cogged V-belt to better cope with the smaller pulley and add more grip.
B; Eliminate the clutch and use a chain drive with a cent. clutch. I hate cent. clutches though and I don't think one would hold up well in this situation.
So, any ideas?
