I'm the happy owner of a '67 Sno-Cat. It's fully functional and in good running shape, but I'm having a bit of an issue with the front set of tracks. I have some excessive wear on the roller bearing support ears which look like they've been wearing against the bottom edge of the guide rail. Most of the rollers still have some decent flange left to them, but I'll have to replace some eventually. I found links to these guys as potential replacements, but has anyone actually used them? https://www.pcimfg.com/portfolio_page/track-rollers/
Back to my original reason for posting though, does anyone have a guide of some sort for how to properly align the tracks and pontoons? How much "sag" or tension do the steelies need? Is it just mis-tensioned if it looks to have toe-out or is that a sign of something else broken? I checked all the axle nuts and tightened them up, is there something else I should be checking? The front tracks seem nice and snug, about 3/4" give if you pull up on either side of the drive gear. Is that too tight? The back tracks seem very loose in comparison, like 2" of give on either side, but they don't have the same wear issue or seem toed-out.
I'll see if I can post some pictures to better show what I'm working with. I've already gone through this: https://ibb.co/jzLR3td and measured up the adjustments to the front pivot plate, got it aligned to within 1/4", but I have nearly 3" of toe out between the front guide rails (inner pontoon side) to the back of the front pontoons. The rear is within 3/4".
Thanks for your help!
