D100 (maintenance and repairs)

[Scrubcadet10]

My local JD dealer has AUC13151 for $307.

 

[StarTech]

I have a John Deere X730 w/54" deck. On line lookup says the spindle is AUC13151, $328.00. Went to my JD dealer, he looked it up and said I need AM14424, $140.00. I compared both and they look the same. Same hole pattern for bolting on the deck, same spindle shaft, same bearings, same blade bolts, etc. why such a big price difference???

I now see what the problem is. You are hijacking the D100 thread.

And you are also posting an incomplete number. It should be AM144424. Plus I hope not just replacing the spindle(s) because of a bearing failure as both AUC13151 and AM144424 uses the same 6205 bearings and seals. The last I rebuilt one is cost the customer $52 in parts plus grease and labor. I don't see any reason to replace the spindle unless the housing is damaged

On top of that the two spindles uses different belt drive pulleys. The AM144424 uses a pulley with OD of 143.260 mm and it is Offset. The AUC13151 uses a pulley that has an OD of 146.8 mm. Not much of a difference but still not the same specs. That is nearly a 1/4 inch difference so that would affect deck belt length especially if you are replacing all three spindle assemblies.

Well I probably never pay what JD has the X730 listed for especially for something with a plastic hood. Boy JD loves the customers.

When I was installing the spindles this evening, I noticed there are shrouds around three of the mounting holes. but one hole doesn't have a shroud. Why would that be?

 

[Scrubcadet10]

is there a slope in the deck that would cause the spindle to sit crooked if it were flat on the bottom?

Put this in the FWIW category! I have 2 versions of the JD Technical Manual for the D100-D170 machines. [The difference is age. The older one does not have my D105 in it because it wasn't out yet. The newer one does] I reviewed the sections in each regarding spindle R&R and there is no mention of that detail(shrouds on 3 of 4) on the bottom of the spindle housing. [Scrub, it's the other side of the spindle housing that mates to the bottom of the deck, which is flat all the way around]

Interestingly enough, the TM's also do not mention taking note of the orientation of the grease fitting on removal or replacement. It does make a difference so that you can grease the spindles without removing the covers or being blocked by parts of the deck. To me, that's the main thing I'd be cognizant of. Orienting the spindle housing with the grease fittings in the direction which gives you the intended/unobstructed access.

Okay, so I'm going to ignore the position of the shrouds and be more mindful of where to locate the grease zerks. Here are pictures of them mounted.

Usually they get fitted pointing backwards so they can be accessed with the deck fully assembled and still in the mower .
This will of course depend upon what type of grease gun you have

Ideally you would give them 1 stroke every month during the mowing season.
