Still sounds like something is binding somewhere

can anyone tell me what should be releasing from this exploded parts view. if I look under my 850 I'm guessing #175 and #178 are baked together and they are releasing fine from #179. Could #176 or #177 be stuck? I have never had this apart so I'm not quite sure how it works under there.

Number 179 should be "Free floating" between the two plates when the clutch is depressed, discs are backed on to 179

#178 is the larger friction disc ( Bolens part # 1714630 )

 

# 180 is the smaller friction disc ( Bolens part # 1717298 )

 

Both of these are bonded to the #179 pulley (sheave).

 

Two #181 Needle bearings ( Bolens part # 1185471 ) are a press-fit in the #179 pulley.  ...These bearings ride on the #182 spacer.

 

When the clutch pedal is pushed down, the #175 rear Clutch flange moves away from the #178 friction disc.

 

The #176 spring causes the pulley assy to move slightly rearward, away from the #183 front clutch flange.

 

The pulley assy now spins freely on the #182 spacer, and the #16 2driveshaft should not turn.

 

When the clutch is released, spring pressure from the large #164 spring compresses the two clutch flanges against the friction discs.

We liked under the tractor today, the pully assembly was stuck to the front friction disk. A couple whacks with a hammer and a brass punch and it was free. Now I have to return the battery to TSC, brand new and it won't turn the Wisconsin over with out assistance.

Ok so it may not be the battery now. Going to try and polarize the start / gen.
