The method also includes coupling a second end portion of the component to an opposite wall of the skid steer loader frame by a mounting system that allows for dimensional differences between the component and the skid steer loader frame. ## Claims ### Claim 1 A mounting method for a skid steer loader, comprising: coupling a first end portion of a component directly to a first wall of a skid steer loader frame; and coupling a second end portion of the component to an opposite wall of the skid steer loader frame by a mounting system that allows for dimensional differences between the component and the skid steer loader frame, wherein coupling the second end portion includes making a variable connection between the second end portion and the opposite wall, wherein making the variable connection includes inserting the second end portion through a first ring having a sloped surface and a second ring having a sloped surface, the second end portion being free to displace through the first and second rings during the coupling of the first end portion. ### Claim 2 (depends on 1) The method of claim 1, wherein directly coupling the first end portion includes making a fixed connection that allows substantially no movement between the first end portion and the first wall. ### Claim 3 (depends on 2) The method of claim 2, wherein making the fixed connection includes attaching a flange of the first end portion to the first wall. ### Claim 4 (depends on 1) The method of claim 1, wherein the second end portion is free to displace through the first and second rings when the first end portion is coupled to the first wall of the skid steer loader frame. ### Claim 5 (depends on 4) The method of claim 4, further including fastening the first ring to the opposite wall. ### Claim 6 (depends on 5) The method of claim 5, further including drawing the second ring closer to the first ring such that the sloped surface of the second ring rides up the sloped surface of the first ring. ### Claim 7 (depends on 6) The method of claim 6, wherein the sloped surface of the second ring riding up the sloped surface of the first ring causes the first ring to grip the second end portion of the component to make a fixed connection. ### Claim 8 (depends on 7) The method of claim 7, further including pushing the second ring away from the first ring via jacking to uncouple the fixed connection. ### Claim 9 (depends on 1) The method of claim 1, wherein the component is a pump-motor bridge. ### Claim 10 (depends on 9) The method of claim 9, wherein the pump-motor is hydraulic. ### Claim 11 (depends on 1) The method of claim 1, wherein the first wall is related to a first chain box, and the second wall is related to a second chain box. ### Claim 12 A mounting method for a skid steer loader, comprising: coupling a first end portion of a pump-motor bridge directly to a first chain box of a skid steer loader frame; and coupling a second end portion of the pump-motor bridge to a second chain box of the skid steer loader frame by a compression sleeve that allows for dimensional differences between the pump-motor bridge and the skid steer loader frame, wherein the compression sleeve grips the second end portion when a sloped surface of a first ring of the compression sleeve is drawn up a sloped surface of a second ring of the compression sleeve. ### Claim 13 (depends on 12) The method of claim 12, wherein the second end portion is a portion of a hydraulic motor. ### Claim 14 (depends on 12) The method of claim 12, further including fastening the first ring to a wall. ### Claim 15 (depends on 12) The method of claim 12, further including pushing the second ring away from the first ring via jacking. ### Claim 16 (depends on 12) The method of claim 12, further including tightening fasteners until a fixed connection is formed between at least one of the first or second ring and the second end portion. ### Claim 17 A mounting method for a skid steer loader, comprising: coupling a first end portion of a pump-motor directly to a first wall of a skid steer loader frame; and coupling a second end portion of the pump-motor to an opposite wall of the skid steer loader frame by a mounting system that allows for dimensional differences between the pump-motor and the skid steer loader frame, wherein coupling the second end portion includes making a variable connection between the second end portion and the opposite wall, wherein making the variable connection includes inserting the second end portion through a first ring having a sloped surface and a second ring having a sloped surface, the second end portion being free to displace through the first and second rings during the coupling of the first end portion, wherein the second end portion is free to displace through the first and second rings when the first end portion is coupled to the first wall of the skid steer loader frame.
