nh rat rod 0 #1 Posted February 3, 2015 while snow blowing with my 416h with 44" 2 stage blower when its under a load I hear a high pitch noise coming from one of the pulleys I think maybe a bearing?? thanks for any help Share this post Link to post Share on other sites
rmaynard 14,898 #2 Posted February 3, 2015 Sounds like a good possibility. Release the belt tension and try turning them by hand. You will soon find which one is the culprit.. Share this post Link to post Share on other sites
nh rat rod 0 #3 Posted February 3, 2015 ok will do I have only had the machine for about a week now so im learning. do you know if you can replace the bearings or do they come free with the pulley?? Share this post Link to post Share on other sites
Don1977 604 #4 Posted February 3, 2015 Those bearings are not replaceable you need a new idler pulley. Share this post Link to post Share on other sites
rmaynard 14,898 #5 Posted February 3, 2015 Idler pulleys are usually reasonably inexpensive. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,499 #6 Posted February 3, 2015 A slipping pto clutch will emit quite a squeal if it is not tight enough to take the load. Try shortening up the trunnion on the clutch rod about 2 turns and see if it goes away. Garry 2 Share this post Link to post Share on other sites

squonk 38,937 #9 Posted February 7, 2015 don't forget the PTO bell bearings. Share this post Link to post Share on other sites
nh rat rod 0 #10 Posted February 7, 2015 I'm not familiar with those. Share this post Link to post Share on other sites
squonk 38,937 #11 Posted February 7, 2015 Undo the PTO linkage and hoop and slide the bell/pulley off. There is a big brg that the pulley rides on the crankshaft with and a smaller outer brg that the stud the hoop pin slides into rides in. 1 Share this post Link to post Share on other sites
