Abstract: An engine and transmission spacer with integrated hydraulic tank preferably includes a spacer case, an engine flange and a transmission flange. The spacer case includes an outer peripheral wall, a first outer wall and a second outer wall. The first outer wall is formed on one end of the outer peripheral wall and the second outer wall is formed on an opposing end of the outer peripheral wall. The engine flange extends from one end of the spacer case and the transmission flange extends from the opposing end thereof. A fluid cavity is formed in an inner surface of the outer peripheral wall, the first outer wall and the second outer wall. At least one pump port is preferably formed through a side of the outer peripheral wall. An oil pump is used to transfer fluid from the fluid cavity to another location.
