John Deere Myth- Don't grease those! 

If you add the grease it may help keep the temperature down on the spindle increasing the life of the spindle.

Pretty sad they have a greaser but the bearings can't get the grease... Remind me of our government....😮

Grease 'em. Running bearings "dry" shortens their life (on anything). My D140 has Zerk (grease) fittings on all three spindles (and elsewhere), for the price of grease (both my time and my $$$), it is well worth the cost to try to lengthen the life. Sadly, out of three spindles, only the one on the left is accessible to a grease gun - the fitting on the right spindle faces inward, the fitting on the center spindle faces backward. Put another way, I have to drop the deck, and I shouldn't have to. Bottom line: maintenance is required. Great series of videos!

Drill and tap unit and remove the inter.covers, then hit it with grease gun every 6 hours of mowing I do new decks all the time and it’s going to pay off in labor and high price parts

I appreciate the in-depth look at this and the detail about how it's put together. I've been working on my parents' LA 145 that sounds like a crop duster when you engage the blades. Pretty sure worn bearings or rusty spindles are the culprit now that I've inspected, adjusted, or replaced just about everything else that could cause excess noise/vibration. I'm not a mechanic but I enjoy the challenge of getting in over my head on a project, so getting a good look at the guts of this part is super helpful. Thanks!

Your absolutely correct Lucas xtra in mine over 500 hours 12 year old machine hit em in April again in July works for me once cavity is full don’t require much to make it burp worth it in my opinion

I heard the same story that i dont have to grease the spindels....I grease them regardless....good thing that I do.:) Thanks for this informative video!

Grease is a carrier for oil. The oil will seep out of the grease and slowly travel to other areas , some oil will get past the seal and lube your bearings. Get a paper shop or house towel and put a shot of grease on it from your grease gun. Set this aside and check it the next several days. You will find the oil seeping out of the grease and traveling outwards in the paper towel, same happens inside the spindle housing. 😮

When you pump the grease and the spindle the grease will push that outer seal off eventually... But who cares least you're getting fresh grease through your bearings

Great no nonsense video. in over 35 years, and I've never replaced a mower deck spindle. I have always preformed PMCS on my mower, always greased the spindles. Use a hand pump grease gun pump, and add in grease until you feel resistance, then stop, no need to over grease.

The China bearings are not of good quality. Its proven with everything they copy. Buy USA made bearings

Don’t matter if they are sealed. They heat up and suck grease into the bearings. Stupidest thing you can do is ignore grease fittings! And that spindle that don’t have a grease fitting I’d be drilling and tapping it for a grease fitting before ever returning it to my customers. You save them money by spending an extra 10 minutes fixing an engineering oversight they will see your commitment and you’ll have a return customer for life. I worked in a fabrication manufacturing shop for twenty five years those sealed bearings with no grease zerk is a joke. It’s a ploy to get you to break equipment in 1/3 of time of a normal bearings life cycle!

If one used good quality sealed bearing and perhaps removed one seal and inspected the grease for quality and quantity, the bearing will last a very long time. The seals on quality bearing are a tight fit. The housing cavity is filled with grease to control the heat generated by the speed of the blades and to reduce the possibly of water/ moisture entering the cavity. If one side of the bearing has the seal removed centrifugal force will cause the grease in the bearing to fly out.

One spindle failed on my s120 with 100 hours.. I can’t install the blade normally because the spindle spins when tightening.. i have to hold the blade all the way up as far as I can then tighten it.

Thank you! GREASE RECOMMENDATION?

Great video! I have a 2-ish year old S170 with about 80 hours on the mower deck. I had some trouble getting grease into the spindles the last time I greased it. I want to replace the grease fittings, but I can't find a part number anywhere for the grease fittings on the spindles. What size are the grease fittings on the AUC15811?

THANKS for a satisfying answer I’ve had on greasing my mower blade bearings. Good Luck with your Utube spot, lm now a subscriber.

Very great video thanks for making it thumbs up :- )

That Toro bearing is not sealed. It is a shielded bearing.

I'm getting a John Deere S100 delivered tomorrow from Home Depot. From my understanding a John Deere tech puts these together for Home Depot, not sure if that is true or not. I'm just curious if I should go ahead and add grease to these before I use the mower or assume that the tech already made sure they were greased properly. What do you say?

I assume you've worked on JDX350s so can you tell me how to get the shaft out of a spindle that's on these mowers? These spindles are made different than the ones in your video. I tried hitting the top of shaft with a hammer but it wouldn't budge so I stopped before I damaged something. Thanks!

If you want non sealed bearings buy non shielded bearings.

I grease my spindle bearings on my JD E140 every month.I have 186 hrs on them. The other day after greasing I’m hearing a squeal underneath for the first 4-5 mins then it stops and sounds normal? Is this too much grease? Is grease heating up?

Thank you sir👍

can you let us know where you get the bearing kits for the Z900 series spindles please mate plus details such as part number? I think I asked before but cant find it

Thank you for this video, very helpful! Would you recommend just pumping grease until you see it oozing out. Or just a few pumps each spindle?

I have a John Deere z665 and I thought the clutch went out so I brought a new one but having same issues the clutch wants to spend but blades not in gauging and make like a binding sound. What are your thoughts the closest John Deere dealer wants $1200

i have d140 and have problem with one is it wort to rebuild it or buy anew one?

👍🏼

You are going to go through 2 or 3 tubes of grease trying to get lube to both bearings. The grease will flow to the bearing with the least tight seal. One end will be a mess with excess grease. Just replace the bearings, cheaper than 3 tubes of grease.

13 minutes on such subject is way too much. The average attention span here on RU-vid is approx 5 minutes on an interesting subject alike this. No offense.
