| Subject: | Re: Loose exhaust pipes on YAK-52 |
If you are unsuccessful at removing the nut and have to cut it off- we have
nuts and can replace it. It will require you sending the section of exhaust
to us to cut the flare off, install the new nut, and weld the flare back on.
Secondly, if the gasket (donut) has chewed away at the exhaust port, we rebu
ild the exhaust ports of cylinders.
Danny is still chunkin away at tool kits, but we have several exhaust nut
pin wrenches available. (as well as our new Propeller hub but
tool<https://picasaweb.google.com/100241385797629503200/ToolsOfBorderAirLtd?authuser=0&feat=directlink>
).
Best to all,
Cliff
