Yes, I have a 702 guard on my 702.  Need some measurements??

 

Elliot, make sure your drive belt is a 5/8 and not 1/2" or less.  The pulleys are made to be able to release the belt out of the notch.  A narrower belt does not do the slack thing properly.

The 702 should have a 1/2" belt shouldn't it?

Right Garry...1/2"...my mistake.  I was going from memory, but I really need a defrag.

Elliot, can you post a couple of pictures of you pulleys and belt set up.  Maybe you have a pulley out of line or maybe a bad bearing in the tension pulley, or the linkage is not right and loose.  Is there a guard on your tension pulley that may be out of line and scraping the belt??

Hi this is with a 1/2 ×71 belt it seems to be the best out of them all.the last 2 pics the clutch  is held down. Thanks

[stevasaurus 22,868]

there is your problem...the belt goes under that stud by the input pulley of the trans.  The belt guard bottom would have the belt in-between that stud.    I have a bolt and a roller on mine...my guard bolts on there.  That is OK but the belt goes under that stud.  That is where you are chewing up belts.

Oh ok I'm on my 4th belt 1/2 ×70-74 using the 5/8 should I go back to the 70inch specs i just reread your reply about taking measurements with all the other belts i had what i thought a unusual amount of rubber debris so their is nothing I'm missing on the guard or block . Thanks i really appreciate  the help i was starting to run out of belts

Great thanks for the info and taking the time to help. That's the way I got it so I thought I was covered

Do not go to 5/8" belts...that was  my mistake.  You want a 1/2" belt that fits.

Okay I'm going to try it later thanks again
