1.0 INTRODUCTION
Performance of the following procedures by the owner and operator should ensure
reliable PTO operation
.
1.1 Part Numbering System
NACD Power Take-Off part numbers have changed in the way they were displayed in
print over the years, primarily due to advances in technology.
The part number format for an NACD Power Take-Off is 4XXXXXAM, where XXXXX
is a 5 digit alpha number unique to that particular assembly. Sub-assemblies or kits
are designated 3XXXXXAM and individual components are designated 2XXXXXAM,
where XXXXX is a 5-digit alpha number unique to that particular sub-assembly, kit or
component.
Previous numbers may have been displayed as:
4-XXXXX, 40XXXXX, 04-XXXXX, or 4-OXXXXX. The unique 5-digit number remains
unchanged, regardless of how the prefix may have been written at one time or another.
1.2 Locating The Part Number And Serial Number
Refer to the nameplate for part number information. The serial number will be stamped
