Portable-type step, rolling, and pulpit ladders The are covered in Section 065-105-803. KS-21415 L1 and L2 rolling platform ladders are covered in Section 065-105-301. The material in Sections 065-105-301, 065-105-802, and 065-105-803 replaces the material formerly contained in Section ,,[ 065-105-801, which is canceled. 1.03
Part 2 covers the piece-part numbers and the corresponding names of the parts which it is practicable to replace in the field. No attempt shall be made to replace parts not designated. Part 2 also contains explanatory figures showing the different parts. 1.04

PIECE-PART DATA
The figures included in this part (Fig. 1 through 10) show the various piece parts of the items and their associated assemblies. The names of parts are also included as far as practicable to facilitate identification.
2.01
The ladders covered in this section have been supplied by the Western Electric Company or by an outside supplier. Parts which are to be furnished by the Western Electric Company are listed by P numbers, while parts furnished by outside suppliers are listed by EP or B numbers. A few parts, peculiar to the older outside suppliers’ ladders, are listed by their KS detail numbers. 2.o2
All ladders manufactured by the Western Electric Company are steel stamped with the characters Western Electric Company, Made in U. S.A., and the ED drawing number. This stamping is located either on the central portion of a side rail or on the bottom of a centrally located step. Old KS ladders usually have the outside suppliers’ nameplate with a stamped KS number located on an inner side rail on the upper portion of the ladder. The newer outside suppliers’ ladders have the KS 2.03
Page
2
number and list number on the outside, the same as Western Electric Company ladders. If no identifying mark can be found on an older-type ladder, it can be assumed that the ladder is a KS ladder. When ordering parts,, the P number, EP number, B number, or KS detail number should be given as well as the name of the part; for example, “Floor Wheel Bearing Detail 20 of KS-5049-01 Ladder” or “P-450354 Wheel Bearing.” Do not refer to BSP numbers or to any information shown in parentheses following the piece-part numbers. 2.04
In the ordering of replacement parts, determine if cotter pins, tab lockwashers, “ANCO” locknuts, mounting screws, or tie rods and bolts are likely to be damaged in the removal of the old part. If there is a possibility that they may not be reused, order the required quantity together with the replacement part. 2.05
lVote: In case of reuse, if a locknut after having been released by a wrench can be backed off by finger pressure it must be replaced by a new locknut.
