Spindle Shaft bearings parts sequence

[Brockport Bill 1,660]

Been doing first ever spindle bearing replacements on 48 inch SD from 1990 vintage -- so moved next to what I thought was going to be the same design and working on different deck, model 05-42mr01, rear discharge -  early 80's vintage -- only to be surprised as newbie its different bearing # and design, plus different sequence of various parts on shaft -- wasn't paying close enough attention and got distracted in middle of project - plus, stupidly didn't take photos -- so need advice from the Forum brains how to put it back together? Looked at online parts diagrams ... but still not sure?

 

First surprise was its not the bearing at the top of shaft but some kind of spacer seal #106075 ? And as attached photo shows the spindle itself has an extra deep seating to accommodate the bearing plus the seal spacer. Second surprise was a smaller shorter tube spacer piece #106070 - that has  two little cut out notches in it -- what the heck to they do?  but most importantly, do the notches point up to top of deck, or face down?

 

Also, where in the sequence does the smaller shorter spacer tube go on the shaft? Is it immediately stacked on top of the main tube  -- or is it at the top of shaft inside the spacer seal? I included photos of both positions. From online diagram, it appears it goes at top inside the top seal?

 

I also noticed the two grease weep holes in the shaft - do the notches in the small shorter spacer tube somehow align with those holes or related in any way???

 

Lastly, the bearings I used on different deck had only one side with rubber seal and the other side no seal - in this deck the top bearing has no rubber seals on either side of bearing -- apparently by design -- thus, i assume i remove the rubber seals when i get the bearing?

 

thanks much!!!!!!!!!!

This should do it for you. Click on the fuzzy picture in the link. On the page that comes up are two pages showing the breakdown of the original spindles and those that replaced it. Just click on them to view.

The IPL (illustrated parts list) can also be downloaded from that page to identify parts.

 

If you want to download the illustrations they came from this manual

Pictures aren't that clear and I am in the same boat. I know the sequence but not whether notches face up or down. Did you figure it out?

@Brockport Bill since you have that shaft removed I recommend  that you use a dremel or sawzall  to cut the the big nut off. Do it in two places but being careful not to damage the threads and use a chisel to spit the nut where you cut to aid in removal. Then use a 3/4-16 die to extend the shaft threads to the end of where the old nut was plus place blue locktite on the new threads just cut and thread on a new 3/4 NF fine jam nut.

 

I have done this about a dozen times now because over  time the big nut will spin on the shaft and you can't remove the blades!

 

The upgraded spindle design used by wheelhorse eliminated the big oversize nut and used a ordinary jam nut in its place.

 

As for question about the spacer I place the Groved side up then plus I remove/delete the woodruff key and use a lock washer. There is a service builten in the files section explaining in more detail.

@Brockport Bill  looking at your rebuild and bearing detail , did you upgrade the lubrication in those bearings ? basically do the similar set up, leaving top and bottom side of bearings with dust seal in place , leaving the inside bottom of bearings exposed to the grease cylinder they are mounted in . since going over to lucas xtra heavy duty , hi temp  polyurea grease, anti sling . no bearing noise or failures . all my decks and , same PTO BEARINGS , have this treatment  . no bearing whining , or related noise . very questionable  lubricant in those bearings, causing failure . this lucas grease  , is made for brutal work , worth a look , pete

That  is a different spindle setup then mine. My interior sleeve has a small hole through both sides to let the grease out and doesn't have the the notched piece. That notched should go on top of the spacer tube.

I would put the notches up to force the grease to the upper bearing gravity is going to take care of the lower one.
