HOUSING 2S7385 - Caterpillar

Use only E7018 Welding electrodes or similar to install the parts of this reinforcement group. Since the rear lifting eyes must be removed and again installed after the reinforcement group is installed, the welder must have the ability to meet AWS B3.0-40 specifications.
1 Cut two pieces (1) of 30.0 (1.18") thick and 90.0 (3.54") wide steel to 1455.0 (57.28") in length. Bend each plate down to the dimensions shown to make a 100.0 R (3.94" R) at locations (A) and (B). Cut two pieces (2) of 25.0 (1.00") thick and 90.0 (3.54") wide steel to 350.0 (13.78") in length. Bend each piece to the dimensions shown. Make an 18.0 (.71") x 45° chamfer (C) along one side of each piece as shown. 2 Cut two pieces (3) of 25.0 X 90.0 (1.0" x 3.54") steel to the dimensions shown. Make 18.0 (.71") x 45° chamfer (D) along one side of each plate. 3 Make two plates (4) from 16.0 (.62") thick steel to the dimensions shown. Make opening (E) in each plate at the dimension shown. Make a 10.0 R (.38" R) along each end of opening (E). Make a 6.0 (.25") x 45° chamfer along each side of plates (4) at end (F). 4 Remove the hood side doors and panels. Use an Arcair torch or similar tool to remove lifting eyes (5) from each side of the rear frame. Tack weld plates (2) and (3) to each side of the rear frame rails at the dimensions shown. Make 18.0 (.71") bevel groove welds along the top of plates (2) and (3). As an optional procedure, 3.0 (.12") fillet welds can be made around the bottom of the plates. Tack weld plate (4) to the frame rail as shown. Make a 6.0 (.25") bevel groove weld along end (F) of plate (4). Make a 10.0 (.38") plug weld in opening (E). Make an 8.0 (.31") fillet weld along section (X). Do not weld along the front of plate (4) to the dimension shown. Make a 10.0 (.38") fillet weld along the bottom of plate (4). Tack weld plate (1) to the top of plate (4). Make an 8.0 (.31") fillet weld along each side of plate (4). Do not weld along the front 25.0 (1.0") of plate (1). Make a 10.0 (.38") bevel groove weld along rear end (Y) of plate (1). Use the same procedure to install the reinforcement plates on the other side of the machine. 5 Grind all the former welds from eye (5). Tack weld eye (5) in position over opening (E) at the location shown. Make a 10.0 (.38") fillet weld with 1.5 (.06") penetration all around eye (5). Tack weld 6K2198 Boss (6) to the left side at approximately the location shown. This boss will be used to hold the hydraulic tubes. Put the engine side guards in position and use plates (1) as a guide and put marks on the side guards. Use a cutting torch to make modifications as
