Installation of the tamping cylinders (cont.)
1. Remove the bars and scrapers, if installed.
2. Put the machine on proper easels, with a minimum height of
31.5" (800 mm), supporting it on the axles. Lock the front
suspension swing yoke properly.
3. Exhaust the tire to 0.34 bar (5 psi) and clean it to ensure a
good tire's assembly on the cylinder.
4. Assemble the tamping cylinders on the tires.
If necessary, lubricate the surface of the tires
with water and soap. NEVER use petroleum
based lubricant (oil, grease or Vaseline).
5. After the assembly, install the tire locks and apply a torque of
140 lb.ft (190 N.m) on the screws.
NOTE: Apply a chemical lock (Loctite) in all fixating screws of
the guide ring.
6. After installing the locks, put the tires in a central position
inside the cylinders, sharing equally the gap between the tire
and the lock.
7. Inflate all the tires with 3.10 - 4.13 bar (45 - 60 psi), according
to the service to be performed, and the soil to be compressed
(for more tamped soils, use the lower pressure limit).
When using the machine mainly as a dozer inflate
all tires with 6,9 bar (100 psi):
8. Apply dry torque of 545 lb.ft - 740 N.m (oiled 487 lb.ft – 660
N.m) on all the screws of the tires.
