An improved idler gear mounting apparatus for use in a disc cutterbar to rotatably mount the idler gear transferring rotational power between drive gears operatively associated with disc cutter assemblies disclosed wherein a spacer member engages both the upper surface and the lower surface of the transmission casing to provide radial support thereof and also engages the inner race of a bearing assembly rotatably mounting the idler gear. A bolt having a head portion received within a recessed portion of the spacer member extends through the spacer member and is threadably engaged with a securing member which in turn engages the lower surface member of the transmission casing. A lip portion of the spacer member engaged with the upper surface of the transmission casing permits the mounting apparatus to be secured between the upper and lower surfaces of the transmission casing and rotatably mount the idler gear. O-rings associated with spacer member and the securing member seal the mounting apparatus to prevent the leakage of fluid from the transmission casing. |
