Figure 1-40 Cylinder Head Measurement Locations 3. The natural warp contained in the casting must be considered when inspecting firedeck straightness with the head unbolted and unclamped. Natural warpage is not a cause for correction. The firedeck (unclamped) must be straight within 0.279 mm (0.011 in.) front-to-rear and 0.076 mm (0.003 in.) side-to-side. Cylinder head specifications are listed in Table 1-32.
If the cylinder head flatness is outside of the specifications, Detroit Diesel Corporation recommends replacing the cylinder head. (Rev. 2005) All information subject to change without notice. 1-50 6SE483 0507 Copyright © 2005 DETROIT DIESEL CORPORATION
