General Description of Model 260 Power Unit
The Model 50 vibrator runs off the APE 260 power unit. The APE 260 has a 260 horsepower CUMMINS
6CT8.3 engine. The engine is mounted to a tubular frame that also serves as a diesel fuel tank. A sheet
metal and tube frame covers the engine and is equipped with locking doors for protection from the
environment. A control panel is located behind one of the doors and comes complete with a 50 foot
control pendant. There are two hydraulic tanks on the power unit. One is the main tank and the other
is a storage tank for extra oil in case the main tank becomes depleted. A hydraulic tank supplies oil to
four pumps. One pump feeds the vibrator motor. A small pump feeds the clamp attachment. The
Vibrator is connected to the power unit via five hydraulic hoses. The two large 1" hoses are the pressure
and return lines for the vibrator motor. The two small 3/8" hoses are for the clamp system and the one
middle sized 3/4" hose is for the vibrator motor case drain line. The hoses are attached to the power
unit by connecting the "quick disconnect fittings" on the end of the hoses leading from the vibrator. The
fittings go on only one way so there is no chance of hooking up the hoses improperly.
WARNING: Clean with ether or a clean rag before installing quick disconnects. Make sure you
seat the quick disconnect fittings all the way tight. Failure to tighten the quick disconnects will
stop the flow of oil and will prevent the vibro from operating. Failure to tighten the clamp fittings
completely tight will cause the jaws to either not open or not close. If this happens you may have
to crack the fitting and bleed off the pressure to release the quick dis-connects.
