Disassembly.
Trailing beam weighs 150 lbs (68 kg). Attach suitable lifting device prior to removal
to prevent possible injury to personnel.
Force required to remove beam end bushing and beam center bushing may exceed 30 tons
(27 metric tons). Use of a press of 60 ton (54 metric tons) capacity or more is required to
remove and install bushings. Use care when pressing out bushings to prevent serious
injury or death to personnel. Always wear eye protection when operating press.
(1)
Position press plate on press.
(2)
Using a lifting device, position trailing
beam (1) on press plate.
(3)
Using beam end bushing remover and press
adapter, press beam end bushing (2) out of
trailing beam (1). Discard beam end
bushing.
(4)
Inspect outer edge of beam center bushing
(3). If outer edge of beam center bushing is
“mushroomed” over face of trailing beam (1),
chisel or file mushroomed steel away.
(5)
Using beam center bushing remover and
press adapter, press beam center bushing (3)
out of trailing beam (1). Discard beam

Cleaning/Inspection.
Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face
shield, and gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and
clothes, and do not breathe vapors. Keep away from heat or flame. Never smoke when
using solvent. The flashpoint for Type II Drycleaning Solvent is 140 degrees F (60 degrees
C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). Failure to do so may
result in injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and
medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts
eyes, immediately flush eyes with water and get immediate medical attention.
(1)
Clean trailing beam with drycleaning solvent.
(2)
Clean trailing beam bushing bores with crocus cloth to remove all scale, rust, and corrosion.
(3)
Inspect trailing beam for cracks, obvious wear, and damage. Replace if damaged.
