Claims
- 1. In a work vehicle having an engine, a muffler for the engine and an exhaust stack system for the muffler, the exhaust stack system comprising:a vertical exhaust outlet stub pipe on the muffler; a first tapered portion on an outer diameter of the exhaust outlet stub pipe; an exhaust stack pipe having a second tapered portion on an inner diameter of a proximal end of the exhaust stack pipe so as to matingly seat on the first tapered portion of the exhaust outlet stub pipe; means for securing the exhaust stack pipe onto the muffler outlet stub pipe comprising a spring clip member having a hooked end for engagement with the exhaust outlet stub pipe and the exhaust stack pipe, the spring clip member including a generally circular spring wire member having a circumferential inner diameter equal to the outer diameter of the proximal end of the exhaust stack pipe; and the exhaust stack pipe has a longitudinal slot near the proximal end and the exhaust outlet stub pipe has a hole in alignment with the longitudinal slot so that the hooked end of the spring clip member can fit through the longitudinal slot and into the alignment hole.
- 2. An exhaust stack system for an engine muffler, the muffler having an exhaust outlet stub pipe having an outer diameter, the exhaust stack system comprising:a first tapered portion on the outer diameter of the exhaust outlet stub pipe: an exhaust stack pipe having a proximal end and a distal end, the proximal end having an outer diameter and an inner diameter, the inner diameter of the proximal end having a second tapered portion so that the second tapered portion matingly seats on the first tapered portion of the exhaust outlet stub pipe; means for securing the second tapered portion on the first tapered portion comprising a spring clip member having a hooked end for engagement with the exhaust outlet stub pipe and the exhaust stack pipe, the spring clip member including a generally circular spring wire member having a circumferential inner diameter equal to the outer diameter of the proximal end of the exhaust stack pipe; and the exhaust stack pipe has a longitudinal slot near the proximal end and the exhaust outlet stub pipe has a hole in alignment with the longitudinal slot so that the hooked end of the spring clip member can fit through the longitudinal slot and into the aligned hole.
- 3. A method for securing a vertical exhaust stack pipe to an engine muffler having a vertically orientated exhaust outlet stub pipe, the method comprising:providing a first tapered portion on an outer diameter of the exhaust outlet stub pipe; providing an exhaust stack pipe having a second tapered portion on an inner diameter of a proximal end of the exhaust stack pipe; seating the second tapered portion of the exhaust stack pipe over the first tapered portion of the exhaust outlet stub pipe; providing a longitudinal slot near the second tapered portion in the exhaust stack pipe; orienting the exhaust stack pipe relative to the exhaust outlet stub pipe; providing a hole near the first tapered portion in the exhaust outlet stub pipe in alignment with the longitudinal slot; and providing a securing means to secure the exhaust stack pipe to the exhaust outlet stub pipe by engagement through the longitudinal slot and the hole, the securing means including a generally circular spring clip having an open portion for engaging around the exhaust stack pipe and a hooked end for engaging in the slot in the exhaust stack pipe and through the hole in the exhaust outlet stub pipe.
