After a loooooong search I found the perfect boots to seal up those big slots in the firewall. Altho these are rubber and will burn after some time my main concern was to keep smoke and fumes out of the cockpit long enough to get the plane safely on the ground. If you can't get it down before these burn through you have much bigger problems. I have seen some nice covers other ZAC builders have fabricated but all of them had a slit and or hole and would let smoke into the foot area. This is a positive seal and will make it much nicer in the winter too. Go to any Yamaha dealer and order these boots and plates. This is a two part deal with the bellows to follow the rod travel and the plates to fasten the boots to the firewall. These are from a 2001 Mountian Max snowmobile so you guys down south will get some REAL strange looks from the Yamaha parts counter guy. The boot part number is Yam: 8CR-2198F-00-00 and is labeled a "cover". The plane # is Yam: 8CR2195E-00-00. Because of the existing rivets in the firewall I was only able to attach the plate with three A-5 rivits and a screw on the bottom. You will have to carve out the top flange of the plate to miss two rivits. For those that have not built their firewalls yet you can incorporate the boots using ZAC called for rivit locations. Also the small end of the boot is 3/4" id and our steering rods are 3/8" od. I had some thick wall round aluminum stock laying around and I made some bushings out of that. You guys can use anything to fill up that space. ie/ take some fuel line and slide it over the rods etc etc. Happy building Ben Haas. N801BH. Note: For additional fire protection, a piece of baffle seal material with a vertical slit can be placed against the firewall in front of the bellows/boot. |
