Ensure cross bracing is provided if all support frames and drive units are removed.

Removal of Backplate and Discharge Lip

Support the backplate with a hoist and lift straps.

Remove the capscrews holding the backplate to the support frame.

Lower the backplate to the ground.

Support the discharge lip with straps and a hoist.

Remove the six capscrews and locknuts holding the discharge lip assembly.

Lower the discharge lip assembly to the ground.

Clamp the brace being removed to the mounting tabs at both ends using a C-clamp.

Hold the hex nuts from below and remove all 3/4” capscrews holding the brace to the support frame.

Support the cross brace and remove the C-clamps from one end at a time while lowering the brace.

Safety and Environmental Precautions

Ensure no solvents such as gasoline, diesel fuel or chlorinated solvents were used to flush bearings.

Check vibrator oil for impurities (oil sample)

Check nuts and bolts for tightness or missing fasteners

Check decks for heavily worn hardware or worn cross members

Check that vibrating unit drive sheave is free of debris and tight on shaft bushing

Check that electric drive motor output sheave is tight on shaft

Inspect friction pucks for wear

Check live frame for cracks or broken welds

Check oil level at both sight gauges

Add additional oil through the oil manifold breather pipe if needed

Check oil level at petcocks on each side of vibrating unit

Inspect breathers for clogs and clean or replace if necessary

Check for oil leakage at bearings, shaft seals, and casing plugs
