RoboFixIt Posted November 2, 2022 Share Posted November 2, 2022 Went to NAPA looking for some bearing grease but they only have the stuff for cars and trucks. I'm not finding that many search results when looking online but I did find a .pdf that recommends A NLGI 2? Quote Link to comment Share on other sites More sharing options...
mrelwood Posted November 2, 2022 Share Posted November 2, 2022 Liqui-Moly Marine Grease is the one that gets easily the most recommendations here. One of it's features is the low viscosity of 100mm2/s. Stiffer greases decrease the range and output power. 1 Quote Link to comment Share on other sites More sharing options...

But it's better suited to that purpose on EUCs than the Mos2 bearing grease I bought before that. Edit: Coming to think of it, I think boat trailer bearings might've been mentioned as an intended target for the product.

I just completely filled both sides of mine with it, and it has never ridden better. Quote Link to comment Share on other sites More sharing options...

MetricUSA Posted November 3, 2022 Share Posted November 3, 2022 You actually should not need grease if the bearings installed were sealed as they should be....you just need to replace only if they fail... Quote Link to comment Share on other sites More sharing options...

Did you find the bearings sounding louder with more friction? I'm having issues with Liqui Moly  Quote Link to comment Share on other sites More sharing options...

RoboFixIt Posted April 10 Author Share Posted April 10 Ok I'm going to call BS on this... Don't use Liqui Moly Marine Grease! Too thick and sticky for bearings! Maybe good for boats but not going to be smooth enough for wheel bearings Quote Link to comment Share on other sites More sharing options...
Cerbera Posted April 10 Share Posted April 10 On 4/1/2024 at 5:34 PM, RoboFixIt said: Is the Liqui Moly Marine Grease still holding up? Yes, but only does so for so long IME. I have done 2 re-greasings in the year and half I have owned this wheel, and I did them to fix a knocking noise that started after I got caught out in a very heavy rainstorm. The first time I did it, the knocking remained gone for aprox 8 months, then came back incrementally, and quieter, so I did it again a month ago, and it remains gone up to the present day. But that's the knocking - you are more concerned with a general rotation / friction noise, which is there on mine, but to much lesser degree, and I haven't noticed that becoming worse since changing the grease, either initially, or thereafter. So perhaps the difference isn't down to the grease at all, but what is going wrong with wear to our various bearings, which is likely to be different, and therefore produce different levels of noise.  Quote Link to comment Share on other sites More sharing options...

I like mine to have 100% grease fill, and a freely rotating wheel bearing, so I dilute the grease first with a quality SAE 75W-90 gear oil.

alcatraz Posted April 11 Share Posted April 11 Bearing grease often liquifies at operating temperature. Meaning it's solid at room temp but with bearing friction it liquifies and as such solid grease is actually an oil when riding. It's also why it escapes your seals if you've damaged them. A tiny tiny gap is enough for it to escape. 1 Quote Link to comment Share on other sites More sharing options...

A tiny tiny gap is enough for it to escape. Unlike in a truck or car at highway speeds for miles and miles, the grease temperature increase would be insignificant in an euc. And the drag in wheel bearings due to grease can be very significant. Even riding in the summer heat, there don't seem to be a perceivable reduction in drag due to the grease. Maybe if the motor is over heated, then the motor covers can get warm or hot. When I examine the grease in my bearings in my T3 after months of riding, the grease fill still appeared to be 100%. Even if grease can leak out, if would take a very long time before enough grease would have escaped to cause bearings noises and premature wear. Bearings failure for me has been entirely due to road salt from riding in the winter months. Â Quote Link to comment Share on other sites More sharing options...
alcatraz Posted April 15 Share Posted April 15 Contaminants can come in too. Not just grease escaping. If the outside of the bearings are sticky with lots of crap it means grease has possibly leaked. Also, the seals can't seal even if new when the alignment is off. So people who constantly replace bearings or pack new grease probably have poor alignment. Bearings that spin fast can reach very high temperatures. Even at slow rpm you can get enough heat to liquify the grease depending on what the grease is. Ideally it should liquify for the lowest resistance (and low heat). Overpacking with grease or using supet thick grease is also bad news because your balls stop rolling. They get dragged around and wear out the bearing in a very short time. The play between the inner and outer race should be and remain very small. Then you get the advertised life of tens of thousands of km. Quote Link to comment Share on other sites More sharing options...

I don't feel any drag or any resistance at all on the wheel and after reading up on this issue I just decided to turn on some music and the knocking sound fades away like a little click track  I'll just replace the bearings in the next week or so anyway and forget about Marine Grease Quote Link to comment Share on other sites More sharing options...
