Part 1 - Don’t trust the “Experts” Grease your mower deck sealed spindle bearings Common sense.

In this video I test the theory of bearing seals preventing grease from entering a bearing. I show a bearing before and after greasing a deck mandrel assembly and prove that grease does penetrate into the bearings. as a side note, consider getting a locking grease fitting for your grease gun. They are worth every penny and will stop the gun from coming off the fitting. one of my top 10 best tools in the shop and i use it every day. here is the link to the one i use. https://amzn.to/3cWBkYA its absolutely impossible for a inner seal on mandrel bearing to prevent pressurized grease from penetrating into the bearings. a grease gun can exert 1,000 to 5,000 PSI. hand held grease guns are extremely powerful. the actual pressure passing through the assembly is relatively low and only a fraction of what can be exerted but my point is that the seal / shield can not stop pressure and grease will pass. I would rethink any advice given from a “mower Mechanic” that is trying to tell you that greasing a deck spindle / mandrel / bearing housing will not Benefit your bearings because of a light duty dust seal / shield that is not capable of stoping grease From passing. Why not test it for yourself if you don’t believe me. But hey, here is a video that can save you time money and iv done the work to show the results. Rather than just blabber on about a theory that I have not tested, I Actually get dirty and show the proof. I highly recumbent buying a locking grease fitting. its something i wish i would have known about a long time ago. the regular style grease fittings pop off with even a small movement or putting the connection at a slight angle but with a locking connection it will save grease and also makes it so you don't have to hold the grease coupling on the zero. now i have both hands to work the gun and I don't waste grease or get greasy. here is also a link for the deck repair rings as i have installed in some of my other videos in case you came from watching one of those videos here is a link the MTD / cub cadet style deck repair rings https://amzn.to/3oGQeok . and here is a link to the john deere 100 series deck repair rings. https://amzn.to/3OF3Ta5 .
