Good Year Wheels and Brakes

'G'day Guys,
Has anybody any experience with Good Year wheels and brakes. I have been given two sets of AS NEW 6.50x10 wheels and brakes ex military helicopter. They have single piston one puck calipers and as new tyres and I would like to use them on my F24W41.I believe they are similar to the original equipment on DeHavilland Beaver. I know they would not be as good as Clevelands but the cost of buying with Australian dollars then shipping makes these ones very attractive. A bonus is not only do the wheels fit the axle but the calipers will bolt onto the Fairchild brake torque plate with just the holes opening out to 5/16".I would be most interested if anyone has an opinion on this.

In order to install these wheels and brakes you will have to come up with APPROVED data for a field approval or hire a DER for engineering approval.
For approved data start by finding out if these are TSO'd, what aircraft they were installed on, if the Hayes original master cylinder will be compatable (ci displacement, amount of pedal travel, etc..)You would be better off to bush the backing plate installation down to 0.250 than to drill tourque plate to 0.3125 because drilling will effect the edge distance and you would then have to prove the tourque plate strength. You will have to prove the brakes will hold for the horsepower and stop at the aircraft at gross wieght adequatly, there is a math formula for that. If you can find the same brakes installed on a aircraft with more horsepower and heavier gross weight (find out that aircrafts master cylinders size) it will make your installation much easier. Will you have to move the axle like the Cleveland installation?
Or you can pay a DER
It sounds harder than it is, make if fun by thinking of it as a challenging research project.

'G'da Jim,
Thanks for the advice. Here in Australia we do not have field approvals as such unless such a mod has been done before and then that approval can be followed. The original approval needs to be done by a certifying engineer who I am sure would require the data you have outlined. It is because of this that I am anxious to find someone who has done it or knows of it being done in order to find out if the system is worthwhile. Yes the axle would need to be moved out just a little, probably the same amount as with Clevelands.
