T6 engine baffling?

[Mike Banks]

Hey everyone, had a quick question for the wix brain trust. We are doing a resto on a Pratt 1340 for display. We are trying to find out the proper location for a piece baffling. We have a section of baffling with a 1.5" ish hole in it and can't determine where it goes. The book indicates one way and a friends T6 has it installed another way. I'll try to get a picture of this section, but it's the only one on a 1340 with a hole in it. We figured one of our esteemed colleagues on wix would would know what number cylinder this piece covers. thanks!

The T-6 1340 had 2 baffles with holes for blast air tubes for both magnetos.
There is another one between cyl 1 & 2 that is a slightly larger for a tube that leads to the heat muff clamped to the exhaust for cockpit heat on non Harvards.

Photo from the BE thread-

Cyl 1 is top middle. #2 is to its left in the photo and the larger tube can be seen in between these.
Mag blast tubes are between #3 and 4 along with 7 and 8.
Cylinders are numbered 1 - 9 CCW in the photo. My son is working on cyl #5 which is the Master Rod on this engine.

Enlighten us on the Willow Grove use of SNJs. How many and what work was done there?
Its so sad to have the quiet sky above us here now.

Fresh out of Aviation Machinist Mate "A" school at Nas New York (Floyd Bennett Field) I was transferred to Nas Wilgro and assigned to the Utility/Training aircraft line.We had 5 SNB-5's,1 JRB-4,8 SNJ-5's.These were used by pilots from surrounding Navy offices,Recruiting stations,Navy yard,Mustin Field and station pilots for proficiency flights.Over time I became an SNJ "Plane Captain" which I was responsible for all preflite insp,postflites,refueling,oiling and fixing minor discrepancies.My first aircraft and was I proud of it.Buno 90986.The weekends were a busy time for us with reserve pilots who came in to drill,these would be pilots not assigned to specific a/c squadrons.2 of us would begin at one end and work our way to the other end of the line and start the engines,set the brakes and go on to the next one.By the time we got to the end the 1st one would have been warmed up enough to perform engine run ups as per preflite procedures.A great learning experience and a start to my 20 year career that my last 14 were as a C118 Flight Engineer.The R985,and R 1340 were pretty reliable engines.The updraft carb on the J had a habit of catching fire with too much prime,but easily put out once the engine started.I could go on and on,still good memories.

Thx for the stories.
I have had my only starting fires with a Corsair.
