Maintenance

Vibrating Shaft Bearings (50 hrs)

The double row of self-aligning ball bearings on the vibrator shaft are special bearings that are not available at the local bearing supply houses. Lubrication of these bearings is very important and should be lubricated after each 50 hours of operation. Rotate roller drum so that grease fittings are towards the lower front.

If it becomes necessary to tear down and reassemble the roller, remove wash out and repack bearing housing with specified grease. After cleaning and checking bearings, they should be lightly packed with the specified grease.

It is essential that no end thrust be applied to these bearings. On reassembly there should be approximately .060" (min) to .120" (max) end float on the vibrator shaft, which may reduce when the shaft reaches working temperature.The bearings must be a light slip fit on the shaft to insure axial freedom.

Hydrostatic Transmission Fluid (50 hrs)

Inspect the fluid level in the hydraulic fluid reservoir every 50 hours of operation, if low, fill with Mobil 300, GM Dextron B or Ford MZC-41A type hydraulic transmission fluid. Change hydraulic transmission fluid on a yearly basis.

Vibrator Clutch Assembly (100 hrs)

The clutch must be greased every 100 hours of operation. Stop the engine with clutch engaged to check V-belt tension. See "ensioning g the V-belts"

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's 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 4400 vpm.

V304 — MAINTENANCE

Scrapper Blades (Daily)

The scrappers 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 scrapper blades.

V-30-4 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.Un-lock the hood retaining latch and lift the hood to gain access to theV-belts. To adjust the travel V-belt, loosen the four mounting screws on the reduction gearbox (Figure 33)
