Landing gear, wheels and brakes (cont.) |

DJ Short has been helping me with the Cleveland wheel and brake conversion. This uses 6.50 x 10 Cleveland wheels part number 40-40A, brake assembly part number 30-56, and brake disc part number 164-30615-1. The wheels are 10 inch diameter (as per original) and the brakes are 6 inch diameter, more than sufficient to brake an aircraft of 1610 lbs gross weight (these brakes are used on Cessna 182’s). The brake disc was selected to be of minimal height, which allows the whole setup to be tucked inside of the wheel and thus inside of the wheel pant. The pictures below will help explain this. |

You can see the holes for the bolts that hold the wheel halves together, I only have two bolts in now. That is where the bigger 10 inch brake disc attached. See how the smaller 6 inch brake disc fits inside the wheel? That small flange area of the brake disc is where the wheel needed a small amount of machining and the three bolt holts drilled. DJ Short machined the wheels. |
|
Notice how the 6 inch brake disc and the brake caliper just fits inside of the 10 inch wheel. |

Cleveland brake cylinders mounted horizontally underneath the floor boards and permitting the use of the original heel brake pedals. |

Looks completely original with newer technology brakes. Plus, spare parts are readily available. |

I ended up having to make a second front half of the tailwheel. There wasn’t enough pivot for my liking, and when I went to install the tailwheel spring, I couldn’t get enough edge distance for the attach bolt without the tailwheel spring hitting the rear half as it pivoted. The new front half only extended the pivot axis aft by about 3/16 of an inch |

I added the steering arm per the Monocoupe print and the 1/4” shock cord for steering. Everything seems to work as it should and there is no interference or rubbing anywhere. |
