(1) 475-1632 Plate
Place 475-1632 Plate (1) and align to front edge of coupler. Apply tack weld.
Ensure that the cover assembly mates properly to the slots in plate (1).

(A) Cover before trimming
(B) Cover after trimming
For machines equipped with electric couplers, extra trimming may be required to the cover assembly. Identify cover assembly (A) and trim as shown in (B).
Illustration 6 g03877889
Lay a 6 mm (0.24 inch) weld all around the bar on both the left and right-hand side of the coupler.
Illustration 7 g03878066
Add a 10 mm (0.4 inch) by 50 mm (2 inch) long weld at location shown in Illustration 7. Repeat process on the other side of coupler frame.
Illustration 8 g03877896
Locate and remove cover plates on left and right side. Repeat this process on the right-hand side.
Illustration 9 g03877906
Attach smaller 388-5207 Plates (gusset) (2) provided in kit to existing base plate and hand tighten bolts for reference. Ensure plates (2) are located on top of the weld on existing gusset plates.
Illustration 10 g03877911
Lay a 6 mm (0.2 inch) weld on either side of the left and right-side plates.
Ensure all metallic debris/weld spatter is removed. Touch up with paint as needed.
Illustration 11 g03877919
Follow Disassembly and Assembly, UENR3731, "Coupler Cylinder - Remove and Install", under section "Installation Procedure", to reinstall electric actuator. Be sure that the actuator is oriented as shown in Illustration 11, with the electric motor pointing downward.
Illustration 12 g03877922
Cycle the coupler tilt cylinders two times (ensuring the coupler hits the lift arm rack stops). On the third time, operate the tilt cylinder gently until only one side is barely touching the coupler stop. Measure largest gap on opposite side.
Illustration 13 g03877932
Low contact for rack stop should be eliminated. Remove material on lift arm or coupler to ensure clearance.Note: If, the measured gap is less than 3 mm (0.12 inch) then no rework is needed.
Illustration 14 g03878465
If the gap is 3 mm (0.12inch) to 6 mm (0.24 inch), remove material either on the lift arm or on the coupler to ensure that gap is less than 3 mm (0.12inch). Use appropriate method to remove material from coupler or lift arm on the opposite side of where it made contact. Ensure no more than 2 mm (0.08 inch) is removed from the coupler cast surface.
Complete update by removing metallic debris/spatter and touch up with paint as necessary.After Rework Procedure
Illustration 15 g03863294
Follow Disassembly and Assembly, UENR3731, "Coupler Cylinder - Remove and Install", to remove the failed coupler, and install the new coupler assembly. Ensure that the actuator is oriented as shown, with the electric motor pointing downwards.
