PTO clutch temperature

Recommended Posts

Hey guys, so the other day I got one of those infrared "contactless" thermometer the other day as an amazon deal of the day.  Tonight I mowed my lawn and when I pulled the tractor back in the garage I decided to shoot the thermometer at various parts of the tractor and I noticed the PTO clutch seemed to be much hotter than normal.  It read as high as 190F, that seems a little hot to me.  Is it normal for them to get this hot or am I looking at a failure of the clutch?

:twocents-02cents:           190F isn't real hot. The crank shaft dissipates some of the engine heat and the magnetic coil is drawing about ten amps witch is 120 watts of power, about the same as a large light bulb. There is no cooling fan or other heat removal mechanism around the clutch so I guess after mowing the yard that would not be excessive.

My clutch sits right below the exhaust on the 16hp Briggs, most of the PTO linkage gets very hot from that too. 190F isn't too bad, you should be able to notice that burning brake/clutch smell when it starts slipping.

Hahaha there's a lot of truth in that and I do enjoy cold beer, I'd rather take care of a problem though before it becomes catastrophic.  The consesus here is that temperature is nothing to worry about, so I won't.  By the way, I see your from Stillwater, what a beautiful area, I love riding snowmobiles in that area during the winter months.

Yes it sure is, it's amazing the uses you can find for it.

      Looking for a PTO for my 310.  Would like the complete assembly, but at very least I need the inner clutch plate, and outer PTO bearing.

      What direction does the front PTO Pulley turn on a wheel horse D180 with a Kohler K482 as you face the front of the tractor?
       
      I want to get a hydraulic pump for a Johnson 10 loader I will be mounting to tractor and want to make sure I get a pump that rotates the correct direction.

      Its been a while since I was able to work on my 416-8 rebuilt and right now the few brain cells are having a tough time.
      I am in the process of putting the wiring harness back in and the problem is the clutch safety switch.
      The arm with the idler wheel that engages the switch is over ridding the switch arm.
      I had tried adjusting the rod from the peddle to the arm but no matter my adjustment I still have the problem
      I am kinda at my wits end on this one.
      Any help will be greatly appreciated

      The clutch spring  on my 308-8 broke, so the tractor stopped dead.   It was easy to see the broken red spring,  after I removed the right rear wheel.   I  was able to order a replacement spring which I replaced today.  Problem now there is too much slack on the drive belt.  The tractor will move, but barely as if the drive belt is not tight and slipping.  It seems that the clutch pulley isn't applying enough force against the belt.  I have  tried adjusting the clutch rod but that doesn't seem to make a difference.  It only changes the position of the clutch pedal .  I don't see any other adjustment option to put more pressure on the drive belt.  The belt is old, but seems acceptable.  Before the clutch spring, broke, the tractor would jump out in any gear.  No slippage.

      Hi All,
       
      My first post on here so apologies in advance for any rookie mistakes.
       
      First off, I am the proud owner of a "new to me" 312-8. I took it out for a spin yesterday and when I engaged the PTO, currently there is a 42 in side discharge mower deck on it, there were sparks flying from the disk directly below the muffler (maybe the flywheel or clutch?). Any idea what that may be and what needs to be addressed?
       
      Thank you !!
