Couple of Hydro questions

Recommended Posts

porschpow

I got a couple of questions here, my (1997-ish) Toro Wheel Horse 520H (hydro) was doing a couple of things that I noticed. First thing I noticed is that after an hour or so of cutting grass, I noticed the hydro temp light went on. The fluid level was fine. I even changed the fluid at the beginning of this season. So I am at a loss as to what is going on.

 

Secondly, I noticed after riding the tractor for a while, when I back off the throttle, I can hear squeaking. It sounds like it is coming from the pulley under the seat ( I am guessing where the hydro fluid pump/fan is).

 

Ay help/ advice/ comments would be appreciated. thanks in advance!

I would pull the seat and rear fenders, oil seepage plus grass dust/chaffe equals a mess on the hydro pump/fins (I thought just using compressed air was enough to remove the gunk) and quite possibly your hydro fan is broken or the bolt has worked loose and not keeping speed with the pulley, Jeff.

I get it, yeah I could see how that can happen.  Do you access the fan/ fan bolt from the side of the tractor?  Do you have to take the rear right tire off?

Depends on how flexible you are, and whats wrong. :-)

 

I would for sure pull the wheel first to check the state of things, and then if repairs / cleaning is required, I would remove what ever part was in the way for that job.

 

You can do it from above too, guess it is a matter of temperament.

      Hey all!
       
      Replacing the drive belt on my 252-h. Anyone know the torque specification for the center screw when I put this pto clutch back on? I know it was on there tight it took a minute for the impact to break it loose. Thanks!

      Hey all,
       
      This pully blew up on me yesterday. Having a hard time IDing the part # or replacements. the 308-8 schematics I've found don't list this part.  Its the pully in the front that runs from the motor to the mowing deck. 
       
      Thanks in advance!

      I need a little part number help.   I'm looking for the part number of the idler pulley that tensions the drive belt on my 857.  The diagram shows the left side of the tractor.  And I can't seem to locate the pulley on the parts drawing.  The bearings have gone out on my tractor's idler.
