- In this video, I go over the different quills/madrils/spindles and how they work. I also go over the best way to grease the inside of the closed bearings. I also go over other useful tips on the spindles.
One of the most down to earth presenters/talkers on TH-cam with good common sense approaches to real problems.
thanks
You have to fill the spindles until the grease starts coming out... That pressure pushes grease into the sealed bearings, so no need for all of this work... Removing seals in order to manually grease will invite dirt & dust (grease is sticky) which may shorten the life of your bearings.
Some great advice here! I've always poped the inner seals out just so grease can easily get in them, but i learned tonight that even with them on, the grease gets in. I have a mower in my shop right now with a blade put on wrong, surprisingly that's not the spindle that's bad. When i mowed lawns i had a customer call and tell me i left a mower blade in her yard. I told her that's impossible, but sure enough. The star had enough grip that when the bolt fell out it stayed on and worked fine. It was laying right where i shut the deck on on the way to the trailer. Figured I'd find the bolt next time i mowed, but never did
Smart. Best video on the topic!
Wow, thanks!
I did this in my shop for years and never had a problem by doing it.
i am in uk and not a lawnmowerer. but i subscribe becuase i respect real. 👍👍
thank you
Thank you for a very educational and needed video. Carry On Sir. Some good advice I will follow.
You are most welcome
Here is what I find when you remove the inner seal and you force the spindle full of grease the outside seal will be forced off. Even if you drill a weep hole this will happen. Now you can end up with grease on the v belt. A better way is to each season take the spindle apart, pry the grease seal off, clean and lube the bearing and reinstall the seal. More work yes.
Practical and proven recommendations, thanks for another rally good video. And, keep up the Great work! 👍👍👍
Thanks for watching!
Outstanding shipmate. Press on. USS Kitty Hawk CV-63. Jan 1980 to July 1983. Grass cutter for life.
My daughters mower, a Husky, came new, with a blade torqued down on the star and mushroomed it out. I took my die grinder with a cone shaped carbide bur to it so the blade would actually go on correctly.
Nicely done!
Thanks!
Quality video and good info. Keep up the good work!
Glad you liked it!
Very nice work. Very interesting
great tips thanks Mark
Any time!
That's all good information. Thanks.
Glad it was helpful!
I use a grease needle that connects to a grease gun. I've also removed grease seals as well.
All I do is take off one seal of the bearing, pack the bearing full of grease, put the seal back on, coat the spindle shaft with grease and put it all back together. Filling that whole spindle housing with grease is doing nothing but wasting (now expensive) grease. It's worked for me for 20+ years and I've never had a bearing failure. A special note: Any new sealed bearing you get, take off one seal, pack it and put the seal back on. The bearing will last 4-5 times longer. They put very little grease in them from the factory. On autos or bikes, the wheel bearings are the same way. Very little grease.
Useful info,- Thank you!
Glad it was helpful!
Simple well done advice
Glad you liked it
Excellent ideals, I appreciate your explanation!!
Thanks for watching!
If you ever talk to bearing engineer hr would be screaming right now.
Engineers...
Very good video thank you very much
Glad you liked it!
Great to know, thank you.
Glad it was helpful!
Great video
Thanks!
I just replaced the spindles on a Husqvarna, I was wondering why the zerks were there on the new ones, I wanted to take the shafts apart to see if the other side of the bearings were off so that grease could get in there, thank you for answering the question I had
Glad I could help
Good video thanks man.
Thanks for watching!
We always did that refurbishing Teletype machines in the sixties.
Thanks Forest and that's all I have to say about that.😊
Glad you enjoyed it
Thank you!
You bet!
Great video. What the hell were the engineers thinking?
I know, right?
Another day I got two water pumps from an elderly lady they had grease cups on them for the bearings. Old cars how did grease zerk on the water pump an oiler on the distributor. Some had grease lyrics of oilers on the generators. Nothing is made to last anymore cheap and disposable like life
Thanks! I have an 11 year old MTD Gold lawn tractor and I cannot count the spindles I have replaced. Usually one or both each year. The last ones I bought have grease fittings, and I have been greasing them. I hope they are not sealed bearings as you discussed. I guess I should take them apart and see for myself.
Glad to help
Why not just pop off the seal, fill the bearings housing directly with grease and then put the cap back on? Seems like theyd get the grease they need and itd be sealed from water and dirt
There shouldn't be any water or dirt in there, shouldn't... Lol. Taking them off and filling the cavity with grease keeps water and dirt out though, and the mass of the grease helps dissipate heat from the bearings as well. Only downside is the cost of filing it with that much grease. I got here tonight seeing if anyone's ever put something in there with the spacer to take up some space, but haven't found anything like that.
I have done that on idler pulleys with no issues.
I agree. Just pack the bearings and reinstall the grease seal. Job done.
I’ve replaced hundreds of spindles over the years, and few(if any) were due to lack of lubrication. If you’re concerned just pack before installing, but leave the metal shields alone. The problem with removing inner seals and filling the cavity with grease is now you have to maintain it. You’re more likely to damage the blade mounting area or crack the housing before the bearing goes bad.
grease does penetrate into the bearings. BUT!! You have to pump 70 times into the grease fitting. I just pack the bearings by hand, just like the front wheel bearings on my ole truck.
Great tip!
Absolutely correct! Most people don't fill the spindle cavity.
Will this work on bearings with no grease fittings? My troybilt deck bearings making noise but not squealing
you can try it
I have repacked the idler pulleys on my deck. I always use wheel bearing grease instead of regular grease.
👍👍👍👍 10,000 Times !
👌👌👍👍
The amount of grease in a sealed bearing is very carefully determined. Loading a bearing up with grease is one of the worst things you can do. A lot of people putting front wheel bearings in a car when they didn't have lifetime sealed bearing, would often over grease them and then think they were poorly made bearings, but that was not correct. The volume of grease and temperature play a part in lubrication. Put too much in and the grease does not get thin enough to get into the bearing, they run dry, and causes failure.
I dissagree. I`ve read about this but hav`nt had any problems filling them with grease.
At last someone who really knows overloading bearings with grease is poor practice. Sealed bearings should never be greased more than 50% to avoid overheating and failure. The seals are best kept in place to exclude contamination of the grease...
Not only do the knock off companies use poorer quality metal, and sometimes not grease the bearings enough, they also may not be using the correct grease for your application...and likely a cheap grease as well.
I repacked some North American bearings that sat in a drawer for many decades. When I get to it, they are to replace the arbor and motor bearings in my Dad's old table saw that I cleaned and aligned and repaired....all but the bearings.
I used a superior grease, so this will be the only time this job needs doing.
What sort of grease do you use? It looks rather pale.
KY is best.
You know when they put a greaser on a spindle that's not usable.. that really shows you how much they care about their customer.. if they would do that I wouldn't put anything past them.. I think they try to make sure they sell you a good paint job.. people just love looking at those new shiny lawn mowers... But they don't understand that it's total garbage...😅
Not really.... if you pump enough grease into the spindle to pack it full and pressurize a bit, the grease WILL push past the seals and enter the bearing. These bearings work best with less grease vs more.
@@dontblameme6328 the greasable bearings never have the shields on them so it's just pure laziness
As a long time maintenance mechanic I would advise just buying new bearings. When a sealed bearing runs dry the lubricant has left the vehicle which leaves behind clay,scoring the bearing. Too much grease will wear out bearing as fast as too little. There's a reason that there isn't much grease in sealed bearings. Also taking out the seal will allow dirt to get in. I preferred NICE bearings with stainless steel shields. 35 years of changing bearings. Believe me.or don't.
What do you mean by too much grease? How would that be detrimental?
Sealed bearings are greased for life. It only takes a small amount of grease at the ball contact point. As the bearing heats up more grease melts and fills this contact area. You are most likely doing damage removing the bearings and greasing them. Most people remove bearings with a hammer. Which is a bad system.
I just remove the inside seal and that’s it
Sir, what you failed to mention is that water, dirt will be able to get to the bearings. Also you are using a large amount of grease just to get to the bearings. Best wishes sir, Ken
If you keep an assembly such as he presented packed with grease water and dirt will not get to the bearing. The alternative is that the factory bearings with seals in place do not receive any grease and wear out quite quickly.
Not so much the amount of the grease but the poor quality of greases use in manufacture. I always clean out the old grease and add a good quality product to replace it.
Great tip!
lol
with that much grease balls will slip, wear out and overheat.
Just don't over grease as you will push the outer seal off the bearings then problems ahead!🤔

So you do this when you tell the customer he needs NEW bearings
Save some time and just pop the cover off. Thats all. You're welcome.
Have you ever just one time pumped grease into the assembly and see where the grease goes once the unit is completely filled? Sadly this is another video misleading people on this topic. Those caps will not stop grease from passing unless the unit has a weep hole. Pump those puppies full and stop wasting time taking the assembly apart to remove the shields. Here is a video I did to show the facts on the matter. th-cam.com/video/PwObkilFXN0/w-d-xo.htmlsi=Wnw6dvzX3jTTV4Hm
If your not going to prove that those won’t take grease your just wasting peoples time and feeding them garbage information. This is a disservice to the DIY community. I’m not saying that removing the shields is a bad idea, but I am saying its pointless to take an assembly apart when you could just grease the assembly the way they are and move on with life. Dont believe me? Just try it. It would be crazy to think someone in the business would not experiment a little and find out the facts. Where does the grease go? If that unit is filled with grease it will then pass into the bearings regardless if it has Rubber or metal shields. Those thin rubber lips won’t stop pressurized grease from passing. Plain and simple. Cold hard facts. Prove your point.
this is just the way i do it. there are many ways of doing things, thats why the the usa is the best
@@lmsmallenginerepair4471 I understand that’s one way to do it, my point is that the shields don’t stop grease and there is no need to take the u it’s apart to achieve the same goal. You can simply test it yourself but hay, whatever you like. Just wanted to mention that it’s most certainly not the only way to get grease in the bearings. Your viewers may be lead to think it’s the only way so for those viewers it’s a disservice.
