Vultee BT-15 exhaust shroud query
Wed Apr 23, 2008 9:33 pm
I'm trying to figure out the p/n's for a set of exhaust shrouds covers (exhaust muffs) for the BT-15 - the Vultee Valiant with the R-975-11 Wright powerplant.
I learned the hard way this weekend that the exhaust shroud cover for the BT-13 with the Pratt R-985 is not even close to the correct shroud for the Wright powerplant. Makes sense, as the engine mount is different, the exhaust system is a different (especially in the mount configuration to the cylinders) and of course, the cowlings and the dishpan are different. I guess I just overlooked the muffs...
P/N's for the Pratt 985 engine follow:
74-58033-37
74-58033-1 and 74-58033-2
I've looked thru what few TO's I have here for the BT-13 and -15 and can't find the Wright shrouds (no pun intended!) referenced.
Anybody with the correct numbers able to help?
