A65 cylinder cooloing baffles

Post by roady0309 » Sun Jun 17, 2018 12:19

Hi can some one help me with some info on my A65 cylinder baffles? I'm trying to find info on how they go between the cylinders one is larger than the other which is top/bottom? I found a PDF a few weeks ago looking for something else and remember it showing each in different colors but did not print it because I was looking for something different. Mine only has 2 pcs plus the spring/wire. I believe what I found the best that I can remember there were more pcs and the baffles were reversed compared to mine. Any help would be appreciated.

Going from memory and at my age that has proved falable, but the inner cylinder baffles the large is on the bottom and the small piece is on the top. Air entering the front is directed to the top of the engine and the rear baffling forces it to be directed down through the cooling fins. The large inner cylinder pieces further redirects it across the bottom of the cylinders for more even cooling.
