约翰迪尔John Deere柴油发动机气缸盖厚度燃烧面平整度磨损极限值参数
检查并清洁气缸盖
1.检查约翰迪尔John Deere柴油发动机燃烧面是否有热罐物理损坏或损坏的迹象损坏、机油或冷却液泄漏或垫片故障解决方案。
如果有证据表明存在3.在化学热罐中清洁气缸盖,或使用物理损伤;例如开裂、磨损、溶剂和刷子。变形或阀座“烧焦”。检查所有气缸盖通道是否受限。4.用压缩空气干燥并吹净所有通道。
2.刮去5上的垫片材料、油、碳和铁锈。重新安装从缸盖和缸盖上拆下的螺塞。使用动力黄铜或铜丝刷拧紧至以下规格。
清洁密封表面。

检查约翰迪尔John Deere柴油发动机气缸盖燃烧面平整度
使用D05012ST精密直尺和塞尺检查缸盖平面度。在多个位置进行纵向、横向和对角检查。
如果任何测量值超过规格,则必须重新表面处理或更换气缸盖。请参见测量气缸盖厚度在这个组的后面。

Inspect and Clean Cylinder Head Serial Number (200,000— )
1. Inspect combustion face for evidence of physical damaged or destroyed by hot tank
damage, oil or coolant leakage, or gasket failure solutions.
replace cylinder head if there is evidence of 3. Clean cylinder head in a chemical hot tank, or with
physical damage; such as cracking, abrasion, solvent and a brush. distortion, or valve seat “torching”. Inspect all
cylinder head passages for restrictions. 4. Dry with compressed air and blow out all passages.
2. Scrape gasket material, oil, carbon, and rust from 5. Reinstall plugs removed from cylinder head and head. Use a powered brass or copper wire brush to tighten to the following specifications.
clean sealing surfaces.

Check Cylinder Head Combustion Face Flatness Serial Number (200,000— )
Check cylinder head flatness using D05012ST Precision Straightedge and feeler gauge. Check lengthwise, crosswise, and diagonally in several places.
If any measurement exceeds specification, the cylinder head must be either resurfaced or replaced. See MEASURE CYLINDER HEAD THICKNESS (200,000— )

Cylinder Head—Maximum Acceptable Out-of-Flat Over
Entire Length or Width ....... 0.08 mm (0.003 in.)
Straightness Per Any 305 mm (12
in.) Length ......... Within 0.025 mm (0.001 in.)
Measure Cylinder Head Thickness Serial Number (200,000— )
Measure head thickness (A) from valve cover gasket rail-to-combustion face.

NOTE: If necessary to resurface cylinder head, a MAXIMUM of 0.762 mm (0.030 in.) can be ground from new part dimension. Remove ONLY what is necessary to restore flatness.
IMPORTANT: After resurfacing, check flatness as described earlier and check surface finish on combustion face of head.
Check valve recess after grinding. (See MEASURE VALVE RECESS SERIAL
NUMBER (200,000— ) earlier in this group.) Valve face may be ground to bring this characteristic within specification.
