Maule Tailwheel

[Clarke Tate]

I have a replacement hard Maule tailwheel. There is a rubber molding line down the center of the rubber tire, protruding about 1/16" or more. Is this smoothed with a fine emery cloth even with the surrounding tire? There are also small bumps on one side of the tire also from the moulding process. I am less concerned about the bumps on the side than I am about the ridge on the tire.

I wouldn't do anything. The line will be gone after one takeoff, if not sooner.

lol, been a long time (too long) since I had to clean all the grass out of my tailwheel.

Your tailwheel looks fine Ron, grass and all. My tailwheel was very greasy before cleaning!

All of the tailwheel parts are cleaned up, the new replacement wheel needed is mounted, and I have a question. The lock pin on the steering arm, when the original parts were put back together, allowed a bit of play. I ordered a new lock pin and this eliminated the play to an extent. The difference in the pin length was tangible. The wheel swivels and locks, but the action seems easier than with the original lock pin. Has anyone replaced the lock pin and knows what effect this has on keeping the tailwheel from swiveling too easily. A photo of the original lock pin and new spring only is attached, as well as a photo showing the original Maule lock pin is longer and the new Maule lock pin TW-13 is shorter.

Have changed lock pins before but I always tailor the "breakout" force to suit my taste by tweaking the cam plate. I prefer the breakout to be as light as possible which requires smoothing out the kinks in the stamped cam plate.

Thanks Marty. it is good to know tweaking the cam plate is possible.

The "breakout" force when the parts were simply cleaned and lubed seems correct. The old grease was so gunked up and stiff that merely working normally again seemed easier.
