(4) Install the second countershaft and compression roll dust guards (6).
(5) Remove the timber blocks from the road roller frame (16).
(6) Install the compression roll housing (par. 158) and connect all linkage, leads, and fuel and water lines.
(7) Fill the compression roll with water if necessary. Lubricate the compression roll bearings.
g. Bearing Adjustment. Turn the adjusting bolts (2, fig. 135) clockwise to tighten and counterclockwise to loosen the
compression roll bearings. Tighten the adjusting bolts until all side play is eliminated from the bearings. Make sure that
the bearings are not binding. Secure the adjusting bolts with the lockwire.
220. Sprinkler Tank
a. General. The sprinkler tank is made of heavy gage steel sheets and is directly welded to the compression roll
housing. The capacity of the sprinkler tank is 130 gallons. The tank must be flushed at least once a year and cleaned with
steam.
b. Inspection. Inspect the sprinkler tank for breaks, cracks, and leaks. Check tile inside of the sprinkler tank with a
small flashlight for accumulations of rust, lime, corrosion, and sediment. Check all the outlet holes and fittings for corroded
or damaged threads.
c. Cleaning. Clean the sprinkler tank with steam pressure and treat it with a rust inhibitor of standard issue.
d. Repair. Weld all minor cracks and breaks by the metal arc welding method, using straight polarity and mild steel
bare or light coated electrodes. Clean the welds and fill the sprinkler tank with clean water. Check the welds for leaks and
reweld if necessary.
e. Water. Do not use water with high mineral content. Do not use rusty water, because it will cause additional rust to
accumulate even more rapidly in the tank. Filter the water if possible to remove all foreign matter such as leaves, grass,
and mud. Drain the sprinkler tank in freezing weather or protect it from freezing by adding antifreeze. Use the sprinkler
system only when rolling wet or tacky paving materials.
