Swing mount location

[Jim Waltz]

Brad,

While castle nuts were used in years past, the truth is you can never get a castle nut tight against the wheel so that it holds the wheel against the axle step.

While it may not seem like a big deal, what happens is the wheel will then work against the axle, causing a thing called "fretting corrosion", which will eventually damage the wheels and the axle.

I use nylock nuts on all my vintage karts with a safety clip.  I tighten the nylock nut to about 150 ft-lbs, and I check the wheels periodically to make sure that they are not wobbling.

Also, don't forget to use split axle collars on each side of the swing mount.  One of our illustrious members showed up at Stockton a few years ago and could not figure out why he would throw his chain every time he went out on the track.

Fortunately I had a couple of spare 1" locking collars, so we got him fixed up right on the spot.

Finally, Teddy's center mount engine is great, but he does usually run a floor-mounted tank.  If you are usding a seat-back, bubble tank it may interfere with the engine/mount location.

Ciao!
