On my way to the LHS to get some new Spur Gears. Said they had 4, better get them all. I have a lot of learning about this truck ahead of me. Seems like I get one thing fixed, run it and fix something else. Ran great in the grass after I installed the new slipper clutch, then one quick trip into the plowed field and no teeth left on the spur gear. Must have had the slipper clutch adjusted to tight. You could still turn it by hand. More learning to do.
