A 128-4773 Lift Bracket Extension 1
A 128-4775 Lift Bracket Extension 1 Start By:
Install the truck body retaining cable. Refer to Disassembly and Assembly, "Truck Body Retaining Cable - Remove and Install".
Remove the axle shafts. Refer to Disassembly and Assembly, "Axle Shafts - Remove".
Remove the transmission and the transfer gears. Refer to Disassembly and Assembly, "Transmission and Transfer Gears - Remove".
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
The space between the body and the frame becomes a zero clearance area when the body is lowered. Failure to install the retaining cable can result in injury or death to personnel working in this area.
At operating temperature, the oil in the power train is hot and under pressure. Hot oil can cause burns. Remove the breather filter cap when the engine is stopped and the breather cap is cool enough to touch by hand.Slowly loosen the breather filter cap in order to release any pressure in the oil tank. Be careful of hot hydraulic oil when any lines are disconnected from the components of the power train.

The differential and bevel gear must be supported in order to avoid personal injury or death.
Personal injury or death can occur from heavy components falling during removal or installation.Properly support the component with a suitable lifting device during removal or installation.
Remove 26 bolts (9), 26 washers, and 26 spacers (10). Leave two bolts (9) in place until Tool (A) is supporting the differential and bevel gear.
