VALVE GP-PITCH RELIEF 3G8078 - Caterpillar

TYPE="LEVEL" DEPTH="1" @@@-->PTO stub shaft (A1) can be supplied with the engine. Axial Drives
A Fenner F80 tyre type coupling should be used, as shown in figure (B). The coupling has a flexible tyre (B1) with a taper lock flange (B2) and a taper lock (B3). The assembly fits on the PTO shaft (B4). The maximum PTO capability including both axial and belt drives are: Notes:* Maximum recommended offtake 2 kW per belt.* Multiple belt driven accessories should as far as possible be distributed evenly on the side of the engine to minimise side loads.* Customers wanting to fit a nonstandard drive pulley or coupling, should ensure the inertia of the added components does not exceed 0.0313 kg/m2.* If you are in any doubt, please contact your distributor.Belt Drives
Standard options are:-* Fenner 5" A section pulley with three grooves (C1) and taper lock (C2).or* A Fenner 5" B section pulley with two grooves (C3) and taper locks (C4).In this case the maximum power which can be taken will be limited by the belts, and it will be necessary to calculate for marginal applications.
Additional inertia must not be added to the P.T.O. shaft without specialist advice. Consult your distributor if you need advice about non-standard drive arrangements.
