AUXILIARY POWER TAKE-OFF ASSEMBLY AND METHOD

摘要

An auxiliary PTO assembly is designed for attaching a front mounted auxiliary rotary driven hydraulic pump to an OEM truck engine. The PTO assembly includes an auxiliary belt drive pulley which is formed by a ring which is shrink-fitted around a harmonic balancer which forms a portion of an OEM fan drive pulley. A bracket attached to the OEM engine is adapted to hold the hydraulic pump and a plurality of idler and tensioner pulleys. Installation of the inventive assembly is relatively simple and straight forward and entails virtually no modification of the OEM components. The entire PTO assembly including the auxiliary drive belt and the hydraulic pump are accommodated behind the original position of the OEM cooling fan such that the fan shaft does not need to be extended.
