Crankcase Assembly
The VT 275 has four main bearings but replaces the traditional individual main bearing caps with a one-piece lower crankcase assembly. The lower crankcase is made of cast iron and is stronger than the individual caps. The lower crankcase is attached to the crankcase with sixteen 14mm main bearing bolts of two lengths with the shorter bolts to the outside. Three additional 8mm bolts are used on each side at the perimeter. The lower crankcase is sealed to the crankcase with two push-in-place seals.
Crankcase and Oil Pan
The upper oil pan bolts to the lower crankcase and is sealed with a full perimeter push-in-place gasket. The lower sheet metal oil pan is sealed to the upper cast aluminum oil pan with a full perimeter push-in-place gasket. The upper oil pan is wider than the crankcase and allows for greater oil pan capacity without increased depth.
The oil pickup is sealed to the upper oil pan with an O-ring and attached with two 6mm bolts. Oil pulled through the oil pickup tube passes through a passage cast in the upper oil pan to the lower crankcase. The lower crankcase has a machined passage that takes oil to a front cover passage that leads to the oil pump. Openings in the upper oil pan allow oil to return to the pan during engine operation but also serve to keep oil in the pan away from the rotating crankshaft.
