T head cotter pins12/18/2023 ![]() Not a very sophisticated method, but screwing the bolt out of the socket and bending the footwell about 1/8 inch or so gave plety of clearance. I blocked the inboard side of the footwell with some wood, and then drove the head of the bolt into the area of the stainless firewall where the hang up was and dented it out. I used the socket/bolt combination as a jack screw. So instead, I got a nice long thick bolt and nut, and a deepwell socket. Malletizing it just wasn't going to happen. I was taxi tesing my Rocket and the right pedal was hanging up badly on the lip of the footwell. It has also been recommended that if you cut this part to shorten it, when you re-weld the part it's a good idea to slightly rotate the flat upright so that the horizontal cross tube of the left and right rudder pedals are parallel.Īlthough I thought just changing the screw on the rudder pedal that was hanging up on the footwell would solve the problem, it DID NOT. Then you can insert a spacer and shift the outboard part of the mechanism away from the firewall footwell and gain adequate clearance. It has also been recommended that prior to pedal assembly that the rudder pedal cross tubing (horizontal part) be cut from the upright thin hangar, and reduced 1/4 inch. Some builders have simply ground the bolt head down or used a pan head bolt, as well as taking a ball peen hammer to the firewall footwell junction and knocked it back. It is recommended that you have at least 1/4 inch clearance between the bolt head and the firewall. This could be an extremely dangerous situation in the air, and especially on the ground. It seems there have been problems with the bolt head hanging up on the firewall and disallowing full travel of the pedals. ![]() **Service Bulletin: 8/05 a service bulletin was issued by TR to ensure adequate clearance between the outside lower brake pedal to rudder pedal attach bolt. Maybe everyone knows this and I am just the last one to find out!Īnyway, in the picture below you can see how he locked the pin into the nut, and nothing is sticking out past the end of the bolt for my foot to catch. I thought this was a bit novel so I showed it to one of the other hangar rats, but it was nothing new to him.Īpparently this is standard practice in some circles. Today I was discussing this with the local AME (A&P in the USA) and he showed me a way to bend the cotter pin so my foot would not catch it. During the inspection the cotter pin was found to be somewhat straightened out giving rise to the potential of it falling out. ![]() The bolt that pivots the bottom of the brake cylinder has to be installed with head toward the center tunnel and the castle nut and cotter pin inside the rudder pedal - where your foot could rub against it. ![]() These run VERY close to the center tunnel. One of the things I found involved my rudder pedals. Nearly 50 hours on the Rocket, weather is lousy so a good time to do a full inspection. ![]()
