A power take-off system and isolation mounting therefor including an isolation member mounted to a vehicle frame bracket. A support brace is fixably mounted to the isolation member. The support brace has mounted thereto a linear displaceable casting aligned to displace in a radial direction relative to the vehicle\s engine torque shaft. The casting is biased in a nominal position. One end of a PTO shaft is rotatably supported within the casting. A first pulley is rotatably mounted to the PTO shaft in close proximity to the casting. The other end of the PTO shaft is rotatably mounted to a frame brace to permit limited pivoting of the PTO shaft thereabout. A second pulley and PTO clutch assembly is drivingly supported on the engine torque shaft and load supported by the support brace such that the belt tension loads between the first and second pulleys are isolated from the engine torque shaft.

A power take-off assembly and isolation mounting arrangement for mounting to the frame of a vehicle having an engine mounted to said frame, said engine having an output shaft in driving communication with the input shaft of a transmission comprising: a formed bracket with a hole therein operatively

A power take-off assembly and isolation mounting arrangement for mounting to the frame of a vehicle having an engine mounted to said frame, said engine having an output shaft in driving communication with the input shaft of a transmission comprising: a formed bracket with a hole therein operatively connected to said frame; a brace having a generally elongated hole formed therein and a key formed thereon; an isolation member mounted to said bracket and said brace such that said bracket radially aligns said hole\s elongation of said brace to the axial extension or projection of said output shaft, thereby permitting limited deflection of said brace from a nominal position; a casting having a keyway formed therein and a bearing seat having a bearing mounted therein, said keyway being sized to slidably receive said key therein and being oriented to maintain radial alignment of said hole\s elongation to said output shaft; means for slidably mounting said casting to said brace such that said key is received in said keyway of said casting and such that said casting can slidably displace coextensive relative to said elongation of said hole in said brace from a nominal biased position, whereby said nominal biased position positions said key in first extreme position in said keyway; a PTO shaft rotatably supported in said bearing seat at one end and extending through said elongated hole of said brace; means, supported by said brace, for providing driving communication between said output shaft of said engine and said PTO shaft; and means for rotatably supporting the other end of said PTO shaft such that said PTO can experience limited pivotal motion thereabout.
