MAINTENANCE
VIBRATING SHAFT BEARINGS
The system is maintenance-free and does not require
lubrication.
HYDROSTATIC TRANSMISSION FLUID (50 HRS)
Inspect the fluid level in the hydraulic fluid reservoir every
50 hours of operation, if low, fill with ExxonMobil Nuto 46
or equivalent.
VIBRATOR CLUTCH ASSEMBLY (50 HRS)
The clutch must be greased every 50 hours of operation
(1 shot). Stop the engine with clutch engaged to check
V-belt tension.
ENGINE AND VIBRATORY SHAFT SPEED CHECK
(100 HRS)
To check the engine and vibratory shaft speed the use of
an "
Vibra-Tak
" tool will be required.
To check engine speed, place the bottom of the Vibra-Tak
tool (knurled cap) on the engine shroud. Move sliding
sleeve to a position where the maximum throw of wire
reed is obtained. Take a reading from edge of sleeve and
multiply reading by 1000. The result is the RPM the engine
is running at.
If the engine RPM speed is too fast or slow, consult the
engine owner's manual on how to adjust the engine speed.
To check the vibrations per minute (vpm) of the roller shaft,
place the bottom of the Vibra-Tak tool (knurled cap) on the
roller drum while the vibrating clutch is engaged. Adjust and
read tool as mentioned above. The
vibratory shaft speed
should be 4200 vpm.
AXLE PILLOW BLOCK BEARING (75 HRS)
Lubricate the axle pillow block bearing every 75 hours with
2 shots of EP-3 grease or equivalent.
STABILIZER ROLLS (75 HRS)
Lubricate the stabilizer rolls in 4 places every 75 hours with
2 shots each of EP-3 grease or equivalent.
SCRAPER BLADES (DAILY)
The scraper blades should be cleaned daily after each
use to prevent the build-up of dirt, mud, tar and any other
foreign matter associated with pavement rolling. Use a
high pressure water jet (500-1000 psi) and a strong brush
to clean the scraper blades.
ROLLER (DAILY)
Clean the roller daily after each use. If using a pressurized
hose keep the pressure between 500 and 1000 psi. Avoid
using harsh chemicals, mild detergent soap will do. Avoid
direct high water pressure to the engine, hoses and decals.
WATER TANK (30 DAYS)
Drain and flush the water tank and spray bars every 30
days. When refilling the water tank, use only clean water.
ADJUSTING OR CHANGING TRAVEL V-BELT
1. Unlock the hood retaining latch and lift the hood to
gain access to the V-belts. To adjust the
travel
V-belt,
loosen the four mounting screws on the reduction
gearbox (Figure 34).
Figure 34. Travel and Vibratory Belts
2.
Use the pry point (Figure 34) to achieve correct amount
of V-belt tension. Tighten gearbox screws and check belt
tension by verifying the amount of deflection when the
belt is pressed midway between the two pulleys. This
deflection should be approximately 3/4 of an inch (2 cm.).
