Inspecting Parts - MCi 102D Series Maintenance Manual

102D SERIES MAINTENANCE MANUAL
solution tanks with a weak alkaline solution. The parts
must stay in the hot solution tanks until they are
completely cleaned and heated.
Drying cleaned parts
Parts must be dried immediately after cleaning. Dry the
parts with clean paper or rags, or with compressed air. Do
not dry bearings by spinning them with compressed air.
Preventing corrosion on cleaned parts
Apply light oil to cleaned and dried parts that are not
damaged and are to be immediately assembled. DO NOT
apply oil to brake linings.
If the parts are to be stored, apply a good corrosion
preventative to all surfaces. DO NOT apply this material to
brake linings.
Store the parts in special paper or another material that
prevents corrosion.
NOTE: make sure all tapered parts are clean and dry,
with no lubricant or corrosion preventative applied to
mating surfaces.

INSPECTING PARTS

Carefully inspect any disassembled parts before
reusing them. Refer to the following guidelines:
1. Inspect and replace any parts that are worn,
cracked, or damaged. Check for cracks using dye
penetrant, magnetic flux, or flourescent particle testing
methods.
2. Measure the king pin bushing inside diameter
using a micrometer and telescoping gauge for taking
measurements (Figure 14).

If the average inside diameter measurement is greater
than the king pin bushing maximum inner diameter in
Table 1 below, install new bushings.
knuckle bore inside diameter in two locations. Always use
a micrometer and telescoping
knuckle bore measurements. Some rounding of the top
and bottom bore edges is acceptable.
Measure the bore in four positions and at two
locations. The two locations must be 90° opposed to
each other. If the average measurement is greater than
the knuckle bore maximum diameter specification in
Table 1, replace the knuckle (Figure 15).
