packings on oil transfer tubes when installing the

oil pump assembly. Make certain oil transfer

tubes aline with openings in crankcase and mesh

oil pump drive gear with accessory drive gear

(fig. 7-10). Check oil pump drive gear to be

certain there is 0.008 to 0.012 inch backlash

between teeth of pump drive gear and accessory

drive gear.
