@ " MANIC MECHANIC " most important thing  i have found for failure in that drive IS generic grease in the bearings . EVEN ON NEW PULLEYS  pocket screwdriver carefully pop off the bearings wide rubber side shield , both sides , carefully wipe out and carb clean flush out remains , when dry repack with lucas  extra heavy duty cassis grease , put seals back in place and install pulleys . that grease is hi temp 560 deg , polyurea rated and also anti sling , no noisy whining bearings , did the grease change over in my 3 decks,  spindles as well as mule drives . smooth solid and quiet ,  my experience , pete

@Snoopy11  thank you for the feed back, just saying what I do to kill off a problem , as referred I  put a lot of hours and  function on any change to verity gain  , works for me , pete

Well, you are 100% right sir.

 

I bought some new pulleys for my deck on one of my recent projects... and there was generic grease in them. The same can be said of wheel bearings.

 

I think, the reason that they do this is so that the bearings won't last, and you will have to buy more bearings. You give advice to outsmart them, @peter lena...

 

Just my thoughts,

@Snoopy11 those same 6203  ( 3/4 )  rsc3  bearings are the most common ceiling fan bearing , suppose you could get  the bearing with a hi temp grease, but from what I  have seen , and the easy replacement of a certified hi temp / polyurea grease , its easy to make your bearings  whining  free. make a point of getting any bearing with a wider rubber side shield , that makes the re grease process very easy  . its also easy to add a press in bronze bushing , to a larger bearing to fit on a 3/8 " mount bolt . like on a drive belt idler pulley , no failure or noise there either . heard a lot of you can't do that , but I  have , keep it greasy pete

Say,

    not that it "should" matter, I wonder if there is a direction for the pulleys with respect to the clips holding the bearings in the pulleys? Clips facing out or in towards the tractor?

" manic mechanic  "  those inner spring clips , do have a slightly concave  outer edge , probably most important detail is some  aerosol lubricate  in their fit grove for easy removal and install . pete

@Snoopy11  long time ago watched a guy beat the hell out of  similar , inner spring clip , the track was loaded with rust , (   sound familiar ? )  since then , spray it down , use the pinch / squeeze tool , to easily move it around and pull it out , like the guy said , keep it greasy , pete

Sorry, not being clear on this here. The flats on the clips I'm aware of, but thanks. Yes, I have freed up many rusty clips. I am refering to the entire pulley, each of the two pullies, which I placed on the mule drive shaft with the clip side facing the tractor. This way the downwards force is against the casting of each pulley and not on the clips.

Should have taken a picture I suppose?

I think I get what you are describing. However, the whole point of the angled pulley shaft on the mule is to balance the forces as the belts turn down from the PTO onto the deck so that there is no major sideways force. If there was force, they'd need a thrust bearing instead of basic ball bearings in the pulleys. If you are getting a lot of sideways force, you may want to check out the other alignments.

Yes, I see, that makes sense to me, no irregular force per say. I thought the angle had to do also with alignment.
