PTO

[JOEPOE1977 0]

Again any help from all you professional people out there would be appreciated. Again I have a 1990 310-8 with a 42 inch recycler deck that is burning up belts. I am sending you a picture of the PTO. I am not really good at this so please be patient. I will answer all emails. Thank you for all the help. Are the bearings good? I tried to get pictures in the sun. I hope this helps. Thank you to all.

Looks good, the only time that bearing spins is when the belt is disengaged.

What does the friction disk (the plate the thing you posted pushes against) look like?

 

Burned belts usual mean drag in teh deck or the mule drive

I hope this is a good picture of it.

Here you go.

Thank you for the invaluable information.

What about the outer bearing on the PTO. They go bad quite often. Napa # PP204RR6

[Ed Kennell 46,557]

Good to see you have figured out how to post pictures and comments on your existing post.     As stated above, the PTO bearing is not involved when the PTO is engaged.   Are you sure you have the correct size belt? If the belt is too narrow it will bottom out in the pulleys and not grip the sides of the VEE as designed.  Can you post a picture of the belt installed and how it fits in the PTO and deck pulleys?

might just be the way it looks in pic but are those hot spots on clutch plate face?

How thick is the clutch lining on the plate?  If is is around 3/32" to 1/8", you are good.  1/16" to 3/32", you are getting iffy.

 

I'm assuming that the belt that is wearing is the one that comes off of the engine and drrives the deck.  Other than maybe a severly worn pulley groove, the PTO clutch normally does not cause wear on the drive belt.  

 

Do all 3 spindles in the deck spin freely?  Does the tensioning puelly on the belt spin freely?  Do both pulleys in the mule drive spin freely?

 

I was mowing one day and started smelling hot rubber.  Turned out that i had a stick jammed in the mule drive that locked up one pulley.

 

to the forum.  You have found probably the best forum for Wheel Horse advice.  Taken as a group, I believe that the regulars here have broken and fixed just about everything on a Wheel Horse that can be broken and fixed.

just a side note don't overdo the grease on that cage bearing, it will bleed out onto you clutch plate and you will have another problem, slipping clutch plate.

[peter lena 9,939]

@JOEPOE1977  that cage bearing  needs a thorough  wipe / and flush out  , first , then a very light  coating of a  POLYUREA  RATED , lubricant , ? mininises sling off , also 550 deg flash point, so it does not, dry out , into a  drag point . lucas xtra hd , green chassis grease , easily  meets those specs . my pto cone easily spins by hand , when disengaged , also  replace the outer  bearing  napa pp204rr6, the burn spots on the disc , are  showing / telling you  what's hanging up , collective / combined  rotational drag , is typically  lubrication failure , that also  shows up in belt  edge wear . every stage of that  , needs , functional detailing  ,  not as difficult as it sounds , pete

burning up belts

Can you see where the smoke is Joe.   If a belt is burning it has to be slipping in the driving pulley(PTO) or the driven pulley(center deck).

[JOEPOE1977 0]

You are talking about the outside bearing of the PTO. Right? Is this the grease that you are talking about? I also check the disk attached to the engine, it is 1/4 inch thick. I check the mule drive the inside pulley or flat pulley does NOT spin as freely as the outside or V pulley. I was informed this is also a good grease. What ever you recommend I will purchase.

[JOEPOE1977 0]

I was intending to just replace all the spindles and the pullys on the deck. Good choice? I am using a Gates 6997 belt. I never had a problem until this recently.

I really did not see any smoke but I could feel and here something unusual, then the belt snapped.

[JOEPOE1977 0]

Here is the belt and picture of it on the PTO. Again thank you for all the help.

[peter lena 9,939]

@JOEPOE1977  yes that is the grease , also have that in all my cleaned out spindle bearings  and mule drive  bearings . personally never trust  any  bearing lube , always based on the cheapest  available , those side grease shields  easily pop off  with a small flat screwdriver or small putty knife , pop them both off , wipe out  and carb cleaner flush , ensuring removal of all related , trouble . repack with lucas green , reinstall  seals , on spindle bearings , leave inner seals   out , so  related grease fitting  can be used . never had any  whyining noise or  related bearing failures , in years of usage , 3 tractors also did this to  my  , units , this is a GOLD MINE AREA , FOR FUNCTIONAL INPROVEMENT . lever action is , solid / smooth / slick and no related , issues . years in use , no failures or issues . never burned out a clutch disc , every  movement hand off  , is seamless , pete
