USING LOADER K-SERIES CENTER ADAPTERS ON J-SERIES BASE EDGES
Illustration 1. J460 Tip And Adapter With A K110 Tip And Adapter
(A) 232-2114 Tip Adapter (K110)
(B) 220-9113 Penetration Plus Tip (K110)
(C) 47.6 mm (1.87 inch)
(D) 54.8 mm (2.16 inch)
(E) 159-0459 Penetration Tip (J460)
(F) 159-0464 Tip Adapter (J460)
The angle of the adapter nose on K-Series loader adapters (15°) is steeper than J-Series adapters (8°). However, the resultant position of the tip remains very close. Illustration 1 shows a J460 tip superimposed over a K110 tip for their respective adapters. Reworking a J600 adapter to a K150 adapter is comparable. Reworking a J550 adapter to a K130 adapter will extend the tip forward approximately 25 mm (1.0 inch). Welding instructions are located in the weld instruction section of this publication.
The time and cost of using loader adapters on J-Series base edges may be acceptable. Fatigue life of the base edge is another aspect that should be considered. Increasing the thickness of the base edge improves the fatigue life of the edge assembly. Using a base edge that is 60 mm (2.4 inch) thick instead of a base edge that is 50 mm (2.0 inch) thick can improve the fatigue life by approximately 3.5 times. The change to a base edge that is 70 mm (2.8 inch) thick instead of a base edge that is 60 mm (2.4 inch) thick can improve the fatigue life by approximately 3 times. Using a base edge that is 80 mm (3.2 inch) thick instead of a base edge that is 70 mm (2.8 inch) thick can improve the fatigue life by approximately 2.5 times. Improved fatigue life should be considered for machines with buckets that are working in severe applications.
USING EXCAVATOR K-SERIES CENTER ADAPTERS ON J-SERIES BASE EDGES
Make spacer plates from 10 mm (0.4 inch) thick T-1 or comparable steel plate, if the existing base edge is reused. If metric plate is not available, 3/8 inch (9.52 mm) plate is acceptable.
Illustration 2. Cardboard Template
Make a template for the spacer plate by placing a piece of cardboard under the top adapter strap up to the bevel angle. Mark the outline of the J-groove for the strap. Refer to Illustration 2.
Illustration 3. Template
(G) 24 mm (0.94 inch)
The adapter will be positioned higher on the base edge bevel. A gap will exist at the bevel transition and would be difficult to weld. Add 24 mm (0.94 inch) to the wide end of the template. Refer to Illustration 3. The addition of 24 mm (0.94 inch) is applicable to all three K-Series conversions.
Illustration 4. Side View Of A Typical Spacer Plate
(G) 24 mm (0.94 inch)
(H) Spacer
(J) 22.5°
(L) 10 mm (0.4 inch)
Use the template and fabricate the number of plates that are needed. Grind a 22.5° chamfer on the 24 mm (0.94 inch) extension of the spacer plate. Refer to Illustration
