ReferenceSpecial Instruction, REHS2336, "Reworking Bores on 797, 797B and 797F Truck Frames, Bodies, and Axle Housings"
Description of Change: The dimension on the part of the frame that is used to mount the rear suspension cylinders has been improved. The new dimension will allow the rear suspension cylinders to be mounted to the frame without interference.
Adaptable To: The improved 279-8896 Support became effective in production with machines LAJ523-UP, and WSP130-UP.
If needed, the improvement to the 279-8896 Support is adaptable to machines LAJ1-522 and WSP1-129. At assembly, the rear suspension cylinders may not assemble to the frame at assembly because the distance between the cylinder supports is too narrow. Refer to Dimension"E" in Illustration "9" in "Rear Support Component Dimensions" in the above listed special instruction. The correct dimension needed to assemble the rear suspension cylinders is provided.
