ri702bill 13,016 #2 Posted 7 hours ago My only concern with shoulder bolts - the aggressive undercut between the inner end of the threads and the working diameter. Side force, even not excessive, can shear them in two. I often specified precision shoulder bolts, as the threads are held very close to being concentric with the working diameter.

peter lena 10,053 #3 Posted 3 hours ago @ri702bill , have years on this , never had a failure , then went after related , pto lever start issue , at battery tray , the heim joint in place of sloppy trundle , initial washer filling play point ,shoulder bolt , as soon as you squeeze the swing lever on plow quadrant lever , the amazing ease is showing you its gain over a chronic issue , never had a failure , solid wire , instantly shows you its difference, blade swings with ease , tractor has bins of them . really never had any failures , also graphited my blade face ? snow slide off is ridiculous , lets you back plow , for easier clearing , pete 1 Share this post Link to post Share on other sites

peter lena 10,053 #5 Posted 31 minutes ago @ri702bill ironically most of the stuff I have changed over to , you don't even initially see, when I did the plow frame over , used a roller stool to scoot around and analyze problem function , that lets you hunt around for every stage of movement . thats where you find the problems , use the same theory to eliminate / chronic problems . w/h tractors are a gold mine for improvement , bought my c-85 new in 82 , love that thing , also have 2 other units . keep in touch , pete 1 Share this post Link to post Share on other sites
