GENERAL | The DYNAPAC CC 21 vibrating roller is primarily de-
signed for compacting asphalt but is also suitable
for the compaction of base courses and fill,
Wide drums and a high working speed make this roller
particularly suitable for work on streets and roads.
The roller is extremely easy to manoeuvre and it
can also be used to advantage on car parks and
industrial yards on minor jobs, such as pavements
and cycle paths, where space is restricted.

The Dynapac CC 21 consists of a front frame and rear
frame connected by an articulated joint.
The roller features articulated steering, which is
accomplished by pivoting the two frame sections in
relation to one another, Steering is servo-assisted
and movement about the pivot point is achieved by
means of two double-acting hydraulic cylinders. The
two frame sections can also rotate about the longi-
tudinal axis of the roller, allowing the machine to
negotiate irregularities inthe ground.
4 CC 21 D-10052-2 Eng
The roller is fitted with an air-cooled four-stroke |
diesel engine that is used for propulsion and driv-
ing the triple pump for the vibration/steering sys-
tems. |
Roller drive is by hydrostatic transmission. The
engine drives a variable displacement hydraulic
pump which, in turn, drives two hydraulic motors.
These hydraulic motors each drive one drum via
drum gears, which reduce the speed of the. hydraulic
motors to a suitable level.
Drum vibration is achieved by means of eccentric
elements journalled in the sides of the drum. These
eccentric elements are so designed that vibration
can be carried out with either high or low ampli-
tude. The eccentric elements are driven by hydrau-
lic motors.

The engine cooling fan is driven from the crank-
shaft by a V-belt. A V-belt monitor is fitted to
prevent the engine overheating and sustaining damage
if the V-belt should break. This causes the horn to
sound if the V-belt breaks. a

Vibration is generated by an eccentric shaft jour-
nalled in two self-aligning roller bearings (5).
The shaft is completely separated from the frame
bearings (9). |
Vibration is generated by fixed and moving weights
on the shaft. The weights "A" (Fig. 7) are free to
move and assume different positions in relation to
each other, depending on the direction in which the
shaft rotates, Changing the direction of rotation
“and consequently the amplitude is accomplished by
means of a control on the instrument panel. At high
amplitude (Fig. 7b) the weights act in unison, at
low amplitudes, on the other hand, the weights
assume positions which reduce the unbalance.
‚The drum is partially filled with oil via the plug
Vibration should not be engaged while the roller
is stationary as no Lubrication of the drum bear-
ings will then take place. Furthermore, the roller
may dig itself into the ground. |
To keep the drum free from adhesive material the
roller is fitted with adjustable scrapers, ribbed
rubber mats and a sprinkler system — see ''Scrapers,
mats, sprinklers'.

4 Suction filter 10 Pressure line
5 Leakage oil line | - main circuit
7 Variable displacement 11 By-pass valve
The hydraulic system for driving the roller con-
sists of a suction filter (4), a variable displace-
ment pump (7), a valve block (3) and two hydraulic
motors (2).
The hydraulic motors are connected to a multi-disc
brake and drum gear - Renondin or Prometheus. See
also under the heading "Brake System".
The variable displacement pump is supplied with oil
under pressure from the feed pump (8) which draws
oil from the hydraulic oil tank (1) through the
suction filter (4).
The main circuit is a closed circuit in which the
oil circulates between the pump and motors. The amount
of oil pumped round is determined by the angle of the
swashplate in the pump, which also regulates the motor
speed. The angle of the swashplate is controlled by
the forward/reverse lever via a servo valve on the
pump. The direction of flow, and consequently the
direction of rotation of the motors, is controlled
by the angle of the swashplate, positive or negative
as the case may be,
CC 21 D-10052-2 Eng
Feed pump circuit
The purpose of the feed pump (8) is to compensate:
for leakage oil losses and to maintain a minimum
pressure in the main circuit and brake circuit,
The feed pump also supplies the main pump servo
valve with oil for operating the swashplate.

The braking system consists of a multi-disc brake
(1) on each drum gear, The brakes are applied auto-
matically when the feed pressure in the brake circuit
drops below 0.75 MPa. The brake is also controlled
by means of a brake valve (4) which is connected to
the engine "ON-OFF" switch.
The brake valve is fitted with a pressure switch
for operating the brake warning lamp. A pressure
switch is also fitted as a safety switch for use
when the roller is parked, i.e. the engine is
switched off,

Oil is supplied to the vibration motors from the
hydraulic oil tank. Return oil from one of the vibra-
tion motors flows directly to the tank. Return oil
from the other vibration motor flows through the oil
cooler (6) where it is cooled before flowing to the

The hydraulic system for steering consists of one
section of the triple pump (5), pilot valve (1)
with valve block (2), filter (3) and steering
cylinders (4). |
The pump supplies oil to the pilot valve (1) which
apportions the right quantity of oil in relation to
the movement of the steering wheel. The oil pressure
actuates the steering cylinders (4) which turn the
frame in the desired direction.

Check that the fuel tank 1s topped up with diesel
fuel. The level of the fuel should reach up to
the filler pipe. Make sure that the tank is never
run dry as air will then enter the system. This
will render the engine difficult or impossible to
start. If air has entered the systems it will
have to be bled - see "Maintenance Instructions"
@ remove: the engine compartment cover and check the
engine oil level. The oil should be between the
=. marks on the dipstick. If the oil 1s below the
lower mark, top up with Shell Rotella TX 0il
10 W/30 or an equivalent grade of oil from any
other reputable manufacturer.
“Never add too much oil - this may damage the
packing boxes of the main bearings. Use the
funnel provided in the tool box when filling up
with oil.
Raise the lide of the battery box and check the
level of the electrolyte in the battery. It
should be approx. 10 mm above the plates - top

Brakes — check
Check that the fuel tank is full of diesel fuel. The
level of the fuel should reach up to the filler pipe.
Make sure that the tank is never run dry as air may
then enter the system.
Remove the engine compartment cover (on the left-
hand side) and check the engine oil level. The oil
should be between the marks on the dipstick (1). If
the level is close to the bottom mark - top up with
type B engine oil, in accordance with the lubri-
cants listed on page 1, or the equivalent grade of
oil from any other reputable manufacturer.
Use the funnel provided in the toolbox when topping
Never add too much oil - this may damage the packing
boxes of the main bearings, etc.
Checking the brakes
In conjunction with the checking of the engine oil
level, inspect the chain and the spring between the
brake contact and the stop control arm on the injec-
tion pump. |
Check the brakes as follows:
1 Start the diesel engine and run it at approx.
1000 rev/min.
2 Pull out the stop control slowly until the brake
warning lamp goes out - but not so far that the
engine stops.
3 Hold the control in this position and move the
forward-reverse lever slowly either forward or

er than about 1 mimite.

what is not working properly. If the mechanic has a clear understanding of the
problem he will be better prepared for the ich and he will also have the necessary
spare parts when he arrives at the jobsite.
Spare parts should be ordered by using the spare parts catalogue. Be sure to follow
the instructions provided in the catalogue for ordering spare parts. Correct
details will ensure prompt delivery.
