Four Wheel Drive.

      Hi  ryf,  here's wishing that  your day goes well for you. 

            Glad to see you get in on this.    wouldn't the belt lose the  " wedge " for grip too soon if the belt was of a diameter that would  "bottom - out  "   in the pulley  ?        Perhaps  a pulley with  holes drilled all the way around the outer sides  for water to escape and to give the belt the needed grip - - - - sorta like traction on a tire  ! ! ! !    of course the pulley would need to be balanced  and  a cast iron pulley would be stronger  and would act like a flywheel - -  - " not wanting to stop due to it's weight " helping  in preventing   the belt from slipping.     Also giving the belt more surface area on the pulley. 

            These thoughts hit me in the form of flying bats going to the far end of the cave to escape the cold.       

            Your input - - - --  -  Have a good one - - - - -Norman

good question, some of the pulley's I've seen that so 5/8th also do 1/2, and the channel is pretty deep for that reason,   they are deep cut stamped steel pulleys, I'm using1 on mine right now for the alternator! I had one for drive as well, but went with a larger diameter cast for more "flywheel"/ inertia weight (it matters for clutch dumping!) and to get the top speed up! that said, the steel stamped one worked fine, and if I wasn't 325lbs, and my cart another 300ish, it wouldn't have mattered, but alas I am a big boy, and still want my fun!

      Hey  ryf,    "clutch  dumping "  ?     I guess  I've been in the cave too long.          Does  that mean that when the clutch is used - - - you lose a bit of forward power  ?        If that being the case - - -  large diameter - - heavy cast iron pulleys would be best all around  ! ! !      Is my thinking on the right track  ?          Sorta sounds like that  "set-up" could be useful in  a  power gain. 

     Your thoughts on this  ?          Take care                   Norman

sorry... no internet.. just getting back...

RAGB= Right Angle Gear Box.../chain = sprocket off the side

what about cogged belts? (kinda like auto belts)  or even grips welded on the inside of the pulley?

      Hey toxic - - - - -  Here's hoping that your day goes well for you,

      I'm not that  "versed"  on these different drive set-ups   BUT   why not concerning the  "  belt drives "       Both ideas sound pretty good to me.   Has anyone experimented with those ideas  - - - if so - - - your findings ? ? ?

     Good thinking  - - - - -Have a good one  - - - -Norman

I have to agree the belt drive may be in an issue with water and such... could go belt at frame level to chain to live axle... that way you could cover the belt with a "scatter shield" and keep all but the deepest water off it. (you'd have to twist the belt 90 deg. and use a jackshaft) just a thought...

   Hi  again Toxic,      Here's wishing that your day goes well for you,

      I've given that idea of twisting the belt  like you suggested  and if  I  remember correct  it would need to be a "long" belt in order to work correct.   I  don't see any problem with a set-up like you mentioned.     Perhaps we can get some of the other members to comment also.    This site is good for  "working out" some of the  "BUGS" before getting into some project too deep only to find more problems. 

      Good thinking - - - -  now all we need is some warm weather  - - - - - sorta like spring         

      Have a good one                        Norman

    Hey  Guys,   Me  Again 

      Another thought came to me some time ago that  I  overlooked mentioning - - - - - I  had decided on going with cast iron "double" pulleys. 

      Sometimes the  "bats"  get in the way  while  I'm thinking                Norman

That's what I have on my Toro. I haven't gotten the cahnce to build the clutch or test it, but I'm thinking having 2 6" double groove pulleys will overcome the deepest of water.

any progress?
