    Eating up spur gear.

    Took the Slayer to our local track as a back up, couple weeks ago landed wrong and got a gear whine, but still running good. Got home looked it over, engine was pushed into spur gear and fins on head are bent. So readjust gear clearance, next week ripped the spur gear in less than a tank, ok guess to much gap. New gear readjust, went to the track, same story, ok try again. New gear readjust and now I notice when looking from the side, the spur gear and the clutch bell sit in an angle, so much that the tube for air cleaner have made contact with spur gear.
    Right now everything transmission and back are of, but can't see any damage or broken parts.
    What parts should I take a closer look at or replace and/or is there a way to adjust the engine angle to spur gear.
    Yes I had fun.

    I'd check the motor mount and the bolts attaching it to the chassis and motor. To bend the head fins it had to take a good hit.

    Agreed. The transmission is light and stayed put, the engine kept moving after the impact and struck the transmission. Replace the engine mount and check the engine block for damage. Replace the head as well.

    So far I found the engine mount broken on the inside where you can't see it. Looked as a small crack, but came apart as I undid the screws. New mount and chassis brace on order.
    It did go fast and high, don't jump as a buggy.
    Thanks for the help.

    Short Course trucks Jump a lot different than buggies. There Suspension travel is shorter than a buggy so if you land hard after a jump you could tear up parts rather quickly. But from what you explain you Slayer took a good hard lick from the ground.
