1.2.1-Vibratory Exciter
The vibratory exciter head consists of four gears turning four eccentric weights driven
by a Volvo Hydraulic Motor at a rate of 1600 vibrations per minute.
All eccentrics are timed to cancel the side forces and sum the up and down forces of
the eccentric weights to create the amplitude necessary to drive or pull the pile.
The vibration of the exciter case is isolated by the use of 16 rubber suppressors and
provides for a maximum line pull of 60 tons of extracting force. The addition of 4 suppressors may
be used to increase to 75 tons maximum pull.
1.2.2-Diesel Hydraulic Power Unit
The 500 diesel hydraulic power unit is equipped with a Caterpillar 3412 Diesel Engine
with a rated output of 700 H.P. The power unit is mounted on a skid type fuel tank base and is
equipped with full engine and hydraulic instrumentation inside the fully enclosed unit. A 30 foot re-
mote control air operated pendant is standard on the Model 500 and allows the operator to move
around for the best view of the worksite.
1.2.3-Hydraulic Hose Bundle
The 500 unit is also equipped with a 150 foot hydraulic hose bundle, standard, consist-
ing of three 50 foot sections.
1.2.4-Hydraulic Clamp Assembly
Various hydraulic clamp types are available for various types of piling. Consult the fac-
tory or your nearest Factory Authorized Representative for the particular clamp assembly required
for your application.

few minutes to recognize and correct minor discrepancies can prevent major repairs at a
later date.
2) Measure the crankcase oil lever. The oil level must be between ADD and FULL marks on
the dipstick. Refer to the Caterpillar Oil capacities and specifications located on the engine
or in the manual for recommended oil types and capacities.
3) Inspect the coolant level. The level must be to the bottom of the radiator filler neck.
4) All guards must be in place. Repair or replace any guards that are missing or damaged.
5) Check the level of the hydraulic oil in the hydraulic sight gauge located on the side of the
hydraulic reservoir. Add as needed per the hydraulic oil specifications located in Section
4.5.1 of this manual.
6) Visually check all hydraulic hoses and fittings for any visible signs of oil leaks and correct
if necessary.
7) Visually inspect all bolts, pins and fasteners used in mounting the sheet metal enclosure,
radiator brackets, oil coolers, hydraulic manifold, hydraulic reservoir and any other visible
components.
8) Check all nuts, bolts, and visible fasteners for any necessary or required maintenance.
Replace any missing or faulty nuts, bolts, fasteners or components as necessary.

or broken prior to using the Exciter.
10) Check the condition of the Movable Jaw Pin, P/N 33040, and replace if loose, cracked or
broken prior to using the Exciter.
11) Check the condition of the Movable Jaw, P/N 32495, for any possible cracks or
damage and replace prior to using the Exciter.

———————————————————————————–——-
15
SECTION 4-MAINTENANCE SECTION 2-continued
4.1-Daily Maintenance-continued
12) Upon lifting the 500 Exciter to a free-hanging position, check the level of the gear
oil in the sight glass located in the lower left hand corner of the case. Try to position
the case as level as possible to achieve the most accurate measure possible.
13) Check the condition of all Vibration Dampeners, P/N 33036, and replace should
any damage or extensive wear be present before using the Exciter.
14) Grease the Clamp Piston Rod, P/N 32529, by using a grease gun and applying
grease to the two alimite fittings located on the sides of the Clamp Housing. This
should be done at least two times a day.
4.2-General Maintenance
4.2.1-Power Unit
1) Perform all Caterpillar maintenance requirements per the Operation and Mainte-
nance Manual.
2) At 250 hours, replace the pre-charge filter elements, P/N 33119 located at the rear
of the engine opposite the instrument panel side of the Power Unit. See the dirt indi-
cator float levels on the side of the filter housing. Replace the elements before the dirt
indicators are in the red area. Check the condition of the hydraulic elements with the
engine running at maximum R.P.M. to obtain an accurate reading.
3) Replace the Hand Pump Filter located on the Hydraulic Reservoir next to the Hand
Pump every 6 months or earlier if conditions exist.
4) Replace the Hydraulic Oil as necessary due to any contamination by foreign materi-
als such as water, dirt, mixtures of incompatible Hydraulic Oils, or any other substance
that cannot be removed by means of the Filter Elements.
5) Replace the Desigant Material located in the Midland Air Dryer once a year or every
500 hours of operation, whichever comes first.

———————————————————————————–——-
16
SECTION 4-MAINTENANCE-continued
4.2.2-Vibratory Exciter
1) Check the Exciter Case gear lube level for signs of moisture or extreme heat. Re-
place if either condition is evident.
2) Replace Gear Oil every 3 months or 100 hours, whichever comes first.

4.4-Torque Specifications
1) Proper torque applied to all the fasteners and bolts on a Vibratory Exciter greatly
reduces systematic problems and frequent repairs. It is therefore extremely impor-
tant that the following chart be followed with as much precision as possible.
2) All torque specs are for lubricated threads. It is recommended that oil be used to
lubricate threads on all fasteners to assure proper torque. DO NOT USE “ANTI-
SEIZE” IN ANY AREA OPEN TO THE GEAR BOX OF THE EXCITER.
THE USE OF LOCTITE WILL ACHIEVE THE SAME LUBRICATION AS
“LUBRICATED TORQUE VALVES”.
3) Listed below are the major fasteners used in the assembly of the H.P.S.I. MODEL
500 VIBRATORY HAMMER. For any information regarding the fasteners used on this
