G'day All Have just replaced leaking seal & collapsed bearings on the front L/H axle of my S130 Bobcat, I left the chain drive all attached & rolled it out of the way to replace the bearings without pulling the whole box apart. Have got it all back together now, just wondering is there any set way of setting the preload on the tapered roller bearings? So you just do the sprocket retainer bolt up FT? Doing this bolt up pulls the shaft through the bearing until it's seated. Any little tips that I haven't thought about? Didn't want to over tighten bolt & load up the bearings to much. Or will it just take it up until it sits on the shoulders of shaft & sprocket? Thanks in advance.
it will only pull the axle through until the sprocket washer is against the end of the axle. when tight as long as you have no axle end play, you're good to go. if you have excessive endplay, ie: the cup seat counterbores are damaged, bobcat has a special washer that will take up (either, i cant remember off the top of my head) 0.005-0.010 of endplay. typically we dont use them. put some loctite on the sprocket bolt, and tighten it up. :drinkup
