side mower 1542sc02 parts, plus 520H grease fittings

[Divemaster2000 13]

Good afternoon!

 

I am hoping somebody can help me identify the correct deck belt for the 1542SC02 42" mower deck.  I have not had success with that.

 

Also- the tip of the grease fitting on the center spindle has broken off.  What do I need to replace it?

 

And, as a general question- where are the grease points on a 1991 Toro Wheelhorse 520H?

 

Thanks!

Sounds like you need the 520 and mower deck owners' manuals to answer the belt and grease point questions. 520 will be in the files section, search with "Tractor 1991 520-H", and be sure to select the option for use all my search terms.

 

Search for the deck manual the same way using only model number.

 

As for the broken off grease zerk on the 42, you are not the first. You'll need a screw extactor sized to thread into the hole so you can unscrew the remaining stub and then put in a new one. Some members do the greasing and then replace the zerk with a plug until the next time it needs greasing. Off hand, I don't know the size but I'd guess ¼-28,

Thank you for the assistance.

 

I had seen the manual for the mowing deck, and it lists three sizes of belts, but I don't see where it says which size for which deck.  I have ordered all three sizes, and none I have received so far seem to fit correctly.  The 1594 belt was way too big.  The 106125 seemed to be just 2-3 inches too big.  I have received a Gates 6738 that is too short and too narrow (3/8"x38"), but have a second one coming that (based on the description) is 1/2"x86", which should be right.  Right?  I sure hope so.

 

I understand now why I didn't see the grease zerk on the diagram, as I didn't know it was called a zerk.  I was looking for a grease fitting.  It is listed in the table as item 22, Part No. 1030.   I will search for that.  I was thinking of pumping some grease straight in until I can find a replacement.  Or, where I have greased up the other two spindles, swapping if out for one of the undamaged ones for now.  What plug do folks use?

 

You've given me some direction.  I haven't found the manual for the tractor yet, but I know there are at least the six 'zerks' in the front steering assembly, so I started with those.

 

Have a great evening!

Searching for the Part number 1030, I am getting Part No. 302-5, as well as a 302-56.  The 302-5 matches the 1/4-28 that you mentioned.

The correct SPINDLE BELT for the 05-42SC-02 is OEM #6738 (86" x 0.5") ....as per the Toro MPV. 

If this belt doesn't fit right, either

(1) the belt tension pulley is stuck (MUST) be free floating...or

(2) it is the wrong size pulley...aka not OEM.   

ps...the FREE FLOATING flat bar that the Idler Pulley is mounted on MUST absoultely be FREE-FLOATING.

The grease zerk you need is #1030.  To prevent future breakage of this grease zerk, use a die grinder and trim off 1/4" or so of the 'pointy end' of the lift rod that is near it...

And if you don't do it, the new one will be broken off the next time you use the deck.

 

I went the extra mile with mine and drilled through the rod that goes into the bracket so I could put a pin in to keep the arm away from the zerk.

Pardon my ignorance... (I am a student observer here in this thread) but... is this due to a design failure...?

Yes the lift rod will rub the grease fitting. I replace mine center fitting with a set screw. It's impossible to get to with the deck in place. I only grease that one when the deck is off.

I would say yes... but the strange thing is that before I rebuilt the deck I NEVER had an issue with the zerk hitting the lift arm and shearing off.

 

After I rebuilt it, the first time I mowed with it I looked it over to make sure all the hardware was still tight (it was) I noticed the zerk sheared off.  I had to EZ-out the broken piece and re-tap the spindle.  

 

I ground off the 1/4" and pinned the rod which holds it away from the zerk.  Also, loosened the hardware on the lift carriage and shifted it as far as the bolt holes would allow to give more clearance.  

 

No more issues now, but you still need to be careful when installing or removing the deck because it's easy to inadvertently hit it and snap it off.

Thank you for the responses.  

 

I'll see about the grinding, but I suspect I will get several replacements for the zerk, just in case.

I know that the zerk comes very close to hitting, but I have never broken one.  I would look at excessive wear on the parts suspending the deck and then follow the adjustments carefully.  The zerk breakage may only be a symptom of larger issues.

Yes there are larger issues, but unless you want to replace all the lift hardware with 30 or 40 years of wear just to save a grease fitting, it's not worth it. My old 48" deck has been used 43 years I keep the spindles and bearings repaired and It still mows good. The loose lift hardware sound like a thrashing machine. I do have another 48" deck that everything is tight so I not going to replace the lift hardware on my old one. I remove the setscrew and replace with the fitting when I grease it.

I did that and found nothing out of the ordinary.  And I'll point out again that for some reason, before I rebuilt the deck last year, I never had an issue with this.  Everything was the same... all the same parts, worn or otherwise, were reinstalled exactly as they came off, and after rebuilding, it hit and broke the zerk.

 

Strange..............

Tt's typical Wheel Horse once they made a design change they stayed with it. That lift design was made on the No Names and was never changes. When it was made the spindles did not have grease fittings that was done with 3/4" keyed spindles, late 70's or early 80's.

You have 2 joints on the lift bar, 8 joints on the deck and 2 more on the deck attachment a little wear on each will allow a lot of movement. I had to weld up the mid attachment an grind it back out to tighten it up.

Jeff... would something like this be helpful in this scenario...?

My problem has been solved by drilling and pinning the lift rod and grinding a little bit off the bottom, so I'm good actually.

 

 

Looks close, but the lift arm is actually about an inch away from the zerk (further from the camera).  All the way in the lowest position there's no issue at all, which is where the deck is in these pictures.  I believe it had hit when it was in the cutting position a couple notches higher.  Before I did this the arm was right on top of the zerk position.

 

Also, since that spindle and zerk is spinning, you can't really relocate it with a hose.

 

The yellow is the part I ground off the end of the arm.

 

 

 

A 90° fitting would make greasing the spindle easier when it's installed under the machine, but it would still stick up the same from the top of the spindle no matter what, so probably no help.  A relocation kit sure would help to get at the one for the steering though!  This one is quite difficult to access.  But for how often that needs doing it's not really worth the cost. (IMHO)

 

 

I have a lock'n'lube coupler on one of my grease guns... love it! Not cheap though!

Jeff, thank you for the photos.  I was going to ask those who had done some grinding how much they took off.  When I get under the tractor, I will take a look.

 

Have a great Sunday afternoon, everybody!
