If you already have an order in process with us, don't panic!

We are still processing and shipping orders from our warehouse as normal even while our site is offline.

Lower Cylinder Air Deflector Plate, Upright Engines, 10mm Head Studs, 40hp-1600cc Upright Engines, EACH, 311-119-317A
Lower Cylinder Air Deflector Plate, Upright Engines, 10mm Head Studs, 40hp-1600cc Upright Engines, Each, 311-119-317A


 
Lower Cylinder Air Deflector Plate, Upright Engines, 10mm Head Studs, 40hp-1600cc Upright Engines, Each, 311-119-317A is the most critical pieces of engine tin on the whole engine! These deflect air to the lower parts of the cylinders, to properly cool them. If these are omitted from the engine, the cooling air simply rushes down between the cylinders, and the bottoms of the cylinders run much hotter than the tops. This creates such uneven temperatures that the cylinders can distort, and the rings then no longer seal the cylinder because it is no longer round, it's Egg Shaped!

These must be installed BEFORE the heads and push rod tubes are installed, unless you are using Spring Loaded Push Rod Tubes. We prefer these square shaped tins over the "Super Cool Tins" that many people use. These also MUST be used in conjunction with "Sled Tins" to keep air rushing beneath the engine from "backing up" the cooling air's escape, out and back! You need TWO of these do to one engine. These snap onto the lower inner head studs, and "block" the air that flows between the cylinders, fore/aft to cool the lower side of the cylinder. These are often missing, and this results in a significant temperature difference from cylinder upper and lower, and lessens cylinder lifespan because they distort and warp (non round).
