ORDERING REPAIR PARTS
ILLUSTRATIONS
This catalog has been arranged to simplify ordering repair parts. Exploded views of various sections of
the mechanism are shown so that the parts may be seen in their actual position in the machine. On the
page opposite the illustration will be found a listing of the parts with their part numbers, descriptions and
the number of pieces required in the particular view being shown.
Numbers in the first column are reference numbers only, and merely indicate the position of that part in
the illustration. Reference numbers should never be used in ordering parts. Always use the part number
listed in the second column.
Component parts of sub-assemblies which can be furnished for repairs are indicated by indenting their
descriptions under the description of the main sub-assembly. Example:
48
29105AK
Crank Assembly, looper driving lever ........................................................... 1
49
22587K
Screw, bearing cap ,(upper) ............................................................ 2
50
56343C
Guide, ball joint ................................................................................ 1
51
56343E
Splasher, oil ....................................................................................... 1
52
22559A
Screw, bearingcap (lower) ............................................................... 2
It will be noted in the above example that the eccentric, ball stud, and bearing are not listed. The
reason is that replacement of these parts individually is not recommended, so the complete sub-assem-
bly should be ordered.
At the back of the book will be found a numerical index of all the parts shown in this book. This will
facilitate locating the illustration and description when only the part number is known.
IDENTIFYING PARTS
Where the construction permits, each part is stamped with its part number. On some of the smaller
parts, and on those where construction does not permit, an identification letter is stamped in to distin-
guish the part from simil’ar ones.
Part numbers represent the same part, regardless of catalog in which they appear.
IMPORTANT! ON ALL ORDERS, PLEASE INCLUDE PART NAME AND STYLE OF MACHINE FOR WHICH PART IS
ORDERED.
