Bearings come in standard sizes. Buy a set of quality bearings and don't over tighten.These are tapered roller bearings with a press in race and a seal on each end of the housing. I have pressed one apart and started to rebuild it but the assembly’s were almost as cheap as the bearing kits.
Do you know what the red grease is for? It is a "sticky" version of grease. Red = sticky. As in it doesn't flow. As in it doesn't move. As in once wiped away, there is no lubrication. Worst grease on the market.I use good red grease
Red and tacky is a #2 NGLI grease. And is recommended for high speed and wheel bearings.Do you know what the red grease is for? It is a "sticky" version of grease. Red = sticky. As in it doesn't flow. As in it doesn't move. As in once wiped away, there is no lubrication. Worst grease on the market.
What you need is the light brown/cream colored old school #2 NGLI bearing grease. Or the black moly flavor. Blue is water resistant for boats.
What would be the best grease to use? I am on vacation and can’t get to the manual from Scag. Seems like I couldn’t find the recommended grease when got the mower.
Hi BrentW,I have the Valvoline Extreme Red in a new dedicated gun just for the spindles. This is the third set of bearings in less than 500 hours service. I am gonna hand pack all the new bearings first and time will tell. None of my bearings have ever failed to the point of seizing up but they had excessive play and noise.
Red and tacky is all I use and buy it by the case. If it were so bad (slomo) how do they sell so much of it? Ha ha 2xDo you know what the red grease is for? It is a "sticky" version of grease.

I use Lucas "Red N Tacky" grease for the 8 zerk lube points on my Liberty Z. It seems to work well for that application.Do you know what the red grease is for? It is a "sticky" version of grease.

All NGLI #2 greases are tacky. Not like Lucas doesn't ever move once coated. Nothing but a sales gimmick. Lucas doesn't make one product that stands above any other similar product.

You are the first I've heard that buy it. LOLRed and tacky is all I use and buy it by the case. If it were so bad (slomo) how do they sell so much of it? Ha ha 2x
Here is Project Farms comparison between Supertech and Lucas Red n TackyYou are the first I've heard that buy it. LOL
Would love someone to show some real testing that proves any Lucas product is better than say wallymart SuperTech grease. Most of it is hype and sales gimmicks. Not just Lucas products either.
What I miss is the old days when you greased driveshafts and front end parts. I, and I know the rest of you old timers, had grease all over yourself LOL. My grease gun today is a filthy EPA slime BIO hazard LOL.
You are looking at it like since the Lucas didn't move it isn't providing lubrication. I see it as the Supertech is no longer lubing because tt has broken down and has been flung out of the bearing. But you are also dismissing that the Lucas had a smaller wear scar, higher resistance to water, lower resistance in rotational force during cold than the Supertech.The heat test was at 191C or 375F. Way hotter than any real world usage. If your bearings are running close to 400F, you got other problems than grease. Is the ST grease even rated that high for temp? I see 300F for ST grease. Lucas I see rated at over 500+F. Lucas is just higher temp rated.
Notice at near 400F, the super extra deluxe tacky red Lucas wonder grease never moved at all. Meaning poor lubrication after one rotation of a bearing or one wiping away of lube. Shows again what I was talking about.
Lucas red is all thickeners. Hardly any oil dropped out at 400F in the video. Thickeners do not lubricate. All they do is thicken.You are looking at it like since the Lucas didn't move it isn't providing lubrication.

I am not saying that the Supertech is a bad grease, and could be adequate for your applications, But for my overall use the Supertech doesn't meet my operational requirements. If I want to repack my wheel bearings the Supertech doesn't meet the temp requirements unless I go to the red Supertech grease.
A few years ago I did use the normal general purpose grease, due to changes in applications had to upgrade to using red grease.
And last year due to another change in operations had to add urea based green grease to the circle. And the green is not compatible with red or general lithium based grease.
But since the new red n tacky is calcium sulfonate thickened and not lithium soap based things could change.
I have seen several cases of grease failure over the years. A couple of those cases was Valvoline synthetic wheel bearing grease. Your trailers don't have brakes and greasable hubs. My trailer has 21 grease zerks. Or how about repacking the wheel bearings on your own vehicles with disc brakes. Can't use general purpose grease on disc brakes systems. Not high enough temperature rating.So you are saying back in the day, you saw failed grease? Now you need a higher temp grease? I can see this in a turbine engine (high revs) but a lawn mower? High temps in spindle bearings at a whopping 3500rpm? Probably faster do to some pulley sizing.
Do you have mower bearings running at 400+F? Truck/car bearings turn super slow. Only reason for the heat requirement is the brake systems. Way different than a mower.
We are talking about the cost difference of a few bucks a tube of regular cheap grease versus better quality red and tacky grease. I like to save money as much as the next guy, however, when it comes to cents per application and giving the customer better quality, the decision is easy. Plus if I use enough grease out of a tube, I charge the customer a small amount.I have seen several cases of grease failure over the years.

I work on some of my own equipment that is not OPE related
Waaaaaaaaay back in time when I was apprenticing automotive, at school the rule was not to overpack grease in wheel bearings, etc meaning pack the bearings properly, apply a thin coat on hub & spindles to prevent corrosion only as it causes heat retention and causes premature bearing wear due to heat. Overpacking a spindle to the point that it oozes out each end to me suggests that the grease is insulating and not allowing ambient air to cool the spindle housing as a whole. Also the waste of grease. Just my 2 cents.Grease not getting past sealed bearings.... In this video, this guy disagrees that bearing seals will block grease from getting to the bearings, and he demonstrates his findings. The seals CAN block the grease if you don't apply grease correctly, and he shows how to do it correctly. The trick is, you have to pump in enough grease to fill the spindle, then pump some more until some squirts out each end. That ensures that grease made its way through the bearings on each end. If you pump in what seems like a normal amount, the spindle won't be full, and if you have sealed bearings, they won't get any grease. It takes a lot of grease to fill a spindle. I have a low end commercial ZTR. I bought it with about 400 hrs on it. When I serviced the deck, I found that none of the spindles were dry, but also, none were full of grease. Two were fine, but one had a lot of play and a lot of wear. I replaced it. I then greased my spindles as the guy in the video recommends. That was only about 30 hrs ago, so I don't have any long term results.
I'm going to disagree that air cools better than grease. Grease will conduct heat way better than air. Wheel bearings have to be removed to be greased. They typically don't get greased through zerk fittings. Any assembly with a zerk fitting (ball joint, tie rod, etc) gets filled until grease comes out somewhere, or until you can feel the boot start to bulge.Waaaaaaaaay back in time when I was apprenticing automotive, at school the rule was not to overpack grease in wheel bearings, etc meaning pack the bearings properly, apply a thin coat on hub & spindles to prevent corrosion only as it causes heat retention and causes premature bearing wear due to heat.

Most people are not going to remove a bearing in a spindle to pack it, before installing it. Nobody is going to remove the bearing once the spindle is installed to pack it at a later date. Pump the spindle full until it comes out is the only practical way. It can take 100-150 pumps sometimes.I'm going to disagree that air cools better than grease.

You are correct that the grease will conduct heat better than the air, but the issue that @woodstover is trying to bring up is that grease also retains the heat longer. Which is/was believed to lead to premature bearing failure. And also the reason most sealed bearings don't appear to have enough grease installed from the factory.I'm going to disagree that air cools better than grease.

I'm having a hard time understanding how this could be. I'm not saying that it's impossible, but I'd like to see proof.That was the concern with overpacking wheel bearings. The extra grease causes heat retention leading to premature bearing failure.

I hope that's not the case. I recently replaced a spindle, and filled it with Lucas Red n Tacky.And something I just thought of was what type of grease is being used in sealed bearings. Are they using urea based grease, and then we are pumping the spindles and bearings full of lithium based grease, and the 2 greases are incompatible with each other leading to early bearing failure.
Agree, The word if true or not about filling housings is anedotal at this point. One source says to not fill a wheel bearing spindle full of grease because the extra heat retention could cause problems. Then there are several trailers with greasable spindles that you are suppose to replace the grease in the spindle every 3000 miles by pumping grease into the spindle until grease comes out clean, basically replacing all the grease in the wheel bearing housing@ILENGINE, I'm no expert in the matter. I'm not a petroleum engineer. I AM an engineer (electrical) and a gearhead (my dad was a professional mechanic), so I'm not totally clueless. But also, my career as an engineer has taught me that I don't know everything. For the assemblies that get filled with grease (ball joints, tie rods, etc), they are typically NOT rotating assemblies. Bearings on rotating assemblies, like wheel bearings, typically get removed and repacked. So I don't know the answer on this one. Filling the spindle until grease squirts out WILL put grease in the bearings, but is filling the spindle going to cause other problems? I don't know. I would like to think that some engineer somewhere knew what he was doing when he put a zerk fitting on his spindle design. Testing this sounds like a mission for Project Farm.
Common sense tells me that grease is good for rapidly spinning parts, and no grease is bad. I think people tend to overthink situations sometimes. I have the original spindles on my 2006 Scag Turf Tiger. Do you think that is because I NEVER greased them?I have learned that the more I think I know, the more I really have yet to learn.
For many years, when I overhaul a deck or replace a spindle, I open the new ones to pack the bearings manually to ensure they have enough extreme pressure (EP) grease. I have always had a great service history using Mystic JT 6 Red EP Grease
I have a Tiger Cat 2 61 in that has gone through way to many spindle assembly's. It has 450 hrs and has already gone through the factory set and now a aftermarket set.

for what it's worth, my soil condition is sandy loam, and the deck bearings on my Gravely were burning out about every 3 months or 30 hours of use. After going through 3 sets of expensive OEM's I switched to Oregon brands spindles. These have lasted over 2 years or around a couple hundred hours .....I have a Tiger Cat 2 61 in that has gone through way to many spindle assembly's.

I enjoy greasing equipment. It gives me a certain sense of satisfaction. When there are not grease zerks where they should be on equipment, I am disappointed.Hi Tiger SE,
I think we both know "common sense" is not common anymore.
I grew up in a poor family where we had to keep everything (vehicles, tractors, mowers) repaired and maintained on a regular basis. We could not easily afford new vehicles or equipment at a moment's notice.
Often times, I still find myself "resurrecting" some old, donated equipment because it still has years of use left in it.
Some I sell and others I keep.
I have not bought a new piece of lawn equipment in 25 years.
For the record: I'm certain you grease spindles like they should be.
Come now! Don’t you know You Get What You Pay For? Life is so simple when one doesn’t question higher and ever higher prices. Just makes the product better! The higher the price the better it must be, right? People wouldn’t pay more if it wasn’t better!Would love someone to show some real testing that proves any Lucas product is better than say wallymart SuperTech grease. Most of it is hype and sales gimmicks. Not just Lucas products either.
