IntroductionSMCS - 1202-010
When the words "use again" are in the description, the specification given can be used to determine if a part can be used again. If the part is equal to or within the specification given, use the part again.
When the word "permissible" is in the description, the specification given is the "maximum or minimum" tolerance permitted before adjustment, repair and/or new parts are needed.
A comparison can be made between the measurements of a worn part and the specifications of a new part to find the amount of wear. A part that is worn can be returned to service if an estimate of the remainder of its service life is good. If a short service life is expected, replace the part.
Reference: See 3176B Diesel Truck Engine, Form No. SENR5561, for Systems Operation, Testing and Adjusting.

C21099P1
NOTE: Take care to avoid mixing metric and inch fasteners. Mismatched or incorrect fasteners can result in mechanical damage or malfunction, or possible personal injury. Original fasteners removed during disassembly should be saved for assembly when possible. If new ones are required, caution must be taken to replace with one that is of same part number and grade.
Metric thread fasteners are identified by material strength (grade) numbers on bolt heads and nuts. Numbers on bolts will be 8.8,10.9, etc. Numbers on nuts will be 8, 10, etc.
Standard Torque For Metric FastenersExceptions to these torques are given in this specification module where needed. Refer to Torque Specification module, Form No. SENR3130, for additional standard torques for both metric and inch fasteners.

Locate as close to the engine inlet manifold as possible (do not mount on engine).
Do not mount in a location that subjects valve assembly and cylinder assembly (1) to temperatures greater than 93.3°C (200°F).
Install valve assembly so cylinder assembly (1) can be installed in a vertical position as shown.

Piston Group.
NOTICE
When handling the piston assembly, be aware that the piston pin plug which fits on the end of the piston pin, is only used to prevent the
piston pin from scuffing the cylinders. It does not retain the pin in the assembly, once the piston assembly is removed from the cylinder, the
pin is free to fall out of the assembly at any time.

Push the crankshaft up against the top bearing. Write the measurement for bearing clearance on line 1 in column (C).
2. Divide the measurement from Step 1 by 2. Write this number on line 1 in columns (B) & (D).
3. Turn the crankshaft to put the dial indicator at (A). Adjust the dial indicator to "0" (zero).
4. Turn the crankshaft counterclockwise to put the dial indicator at (B). Write the measurement in the chart.
5. Turn the crankshaft counterclockwise to put the dial indicator at (C). Write the measurement in the chart.
6. Turn the crankshaft counterclockwise to put the dial indicator at (D). Write the measurement in the chart.
7. Add lines I and II by columns.
8. Subtract the smaller number from the larger number in line III in columns (B) & (D). The result is the horizontal "eccentricity" (out of round). Line III, column (C) is the vertical eccentricity.
