6-5 FEED RAM ASSEMBLY REPAIR INSTRUCTIONS

removed with a chain wrench. Slide nut and lower gland off end of kelly bar. Loosen the set screw that
locks upper packing nut in place. This nut has left hand threads and may be removed with a chain wrench
even though the amount of working room is limited. Allow nut and upper gland to slide down main drive
until they rest against main drive housing. Start digger engine and very slowly actuate the kelly bar valve
handle as to apply up-pressure to the assembly. This will force both the upper packing set and the lower
