MalMac 1,332 #1 Posted January 11, 2014 I picked up a 95 single chute snowblower a couple of months back. As I was cleaning it up I had to get a lot of grease off of it. The guy who I got it from was not scared to grease it. He left a lot of excess grease all over the place, guess he thought it would help protect the finish. In some ways it did after a good power washing it looked like new. Anyway upon the finale cleaning I discovered that the thing has got sealed bearings on it. Why in the world would there be grease zerks on there? They come from the factory like that? Share this post Link to post Share on other sites

MalMac 1,332 #3 Posted January 11, 2014 I went back earlier and looked at Hydro post and totally missed that. Still seems kinda goofy to me. I guess a little grease might help keep some water out. But than again what does the term sealed suppose to mean. If it were not for a winter application it would be a good way to attract dirt. A lot of times I have a different take on things VS. the engineers who design things. Share this post Link to post Share on other sites
shorts 182 #4 Posted January 11, 2014 Actually a layer of grease will also help to stop dust from getting to the seal and compromising it's integrety Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,495 #5 Posted January 11, 2014 If these are self-aligning bearings there may be a small hole in the outter race for the grease to enter. Garry Share this post Link to post Share on other sites
can whlvr 994 #6 Posted January 12, 2014 the sealed bearings we tend to use for our garden tractor stuff arnt sealed that great,so once the grease gets moving around and warms up it will work its way into the bearing,i have taken the seal out on one side for mower spindles that come (sealed) Share this post Link to post Share on other sites
Kelly 1,033 #7 Posted January 12, 2014 I replaced the bearings in my tall shoot blower a few years ago, the outer part of the bearing has tiny holes in it to allow new grease in, the older blowers are sealed with no holes so no need for the grease zerks Share this post Link to post Share on other sites
Hydro 131 #8 Posted January 14, 2014 I thought about that whole issue after Shorts explained it and a layer of grease cannot be a bad thing. Especially now that I have $7.00 bearings compared to $60.00 bearings. MalMac I packed mine tight until the grease came out between the keepers...it can't hurt. Ain't no dust in the winter and a change of grease in the summer won't be any different than touching up bearing buddies on a trailer! Share this post Link to post Share on other sites
