安裝6081強(qiáng)鹿約翰迪爾柴油發(fā)動(dòng)機(jī)氣缸蓋和帶帽螺釘扭矩參數(shù)方法

重要事項(xiàng)：始終徹底檢查新氣缸蓋墊片是否存在制造缺陷。退回任何未通過檢查的墊片。

確保氣缸蓋和缸體墊片表面清潔、干燥且無任何油安裝氣缸蓋

1.將新的缸蓋墊片放在缸體上。不要在墊片上使用密封劑；安裝干燥。

重要事項(xiàng)：如果缸蓋降到缸體上，并且缸蓋在定位銷上的位置不正確，則拆下缸蓋并安裝新墊片。不要再次嘗試將氣缸蓋重新放置在同一墊片上，因?yàn)榉阑瓠h(huán)可能會(huì)損壞。

2.使用適當(dāng)?shù)钠鸬踉O(shè)備將氣缸蓋均勻地降到缸體上的正確位置。確保缸蓋正確定位在定位銷上，并平放在缸體頂部甲板上。

重要事項(xiàng)：僅建議在6081強(qiáng)鹿約翰迪爾柴油發(fā)動(dòng)機(jī)上使用標(biāo)有“特殊”（上圖）的ASTM 180級(jí)法蘭頭螺釘。安裝氣缸蓋時(shí)，務(wù)必使用新的帶帽螺釘。帶帽螺釘只能使用一次。

不要使用多粘度油潤滑帶帽螺釘，建議使用SAE30。

3.將整個(gè)帶帽螺釘浸入清潔的SAE30強(qiáng)鹿約翰迪爾柴油發(fā)動(dòng)機(jī)機(jī)油中。讓多余的油滴下。

4.將標(biāo)記為“特殊”的正確長度帶帽螺釘安裝在所示的正確位置，并使用本組下一步所述的扭矩-屈服擰緊程序擰緊。參見扭矩-屈服帶“特殊”序列號(hào)（-199999）的180級(jí)法蘭頭帶帽螺釘在這個(gè)組中。

3.使用防油筆、鉛筆或記號(hào)筆，在每個(gè)帶帽螺釘頭的整個(gè)頂部繪制一條平行于曲軸的線。這條線將用作參考標(biāo)記。

重要事項(xiàng)：如果帶帽螺釘意外擰緊超過90 在任何一個(gè)順序中，不要松開帶帽螺釘，而是在下一個(gè)擰緊順序中進(jìn)行調(diào)整。

4.依次（從1號(hào)帶帽螺釘開始，然后繼續(xù)穿過帶帽螺釘26），將每個(gè)帶帽螺釘轉(zhuǎn)動(dòng)90. 帶帽螺釘頂部的線將垂直于曲軸。

5.再次，依次（從1號(hào)帶帽螺釘開始，然后穿過26號(hào)帶帽螺絲）將每個(gè)帶帽螺絲旋轉(zhuǎn)90. 帶帽螺釘頂部的管路現(xiàn)在將與曲軸平行。

6.最后，依次（從1號(hào)帶帽螺釘開始，然后穿過26號(hào)帶帽螺絲）。將每個(gè)帶帽螺釘轉(zhuǎn)動(dòng)90度, 使得帶帽螺釘頂部的線盡可能接近于垂直于曲軸。不需要在扳手的一次擺動(dòng)中獲得最后一圈。步驟4、5和6的總轉(zhuǎn)動(dòng)量為270  5..

重要事項(xiàng)：有頭螺釘不得擰緊扭矩，以使有頭螺釘擰緊

Install Cylinder Head and Cap Screws Serial Number ( —199,999)

IMPORTANT: ALWAYS thoroughly inspect new cylinder head gasket for possible manufacturing imperfections. Return any gasket that does not pass inspection.

Be sure cylinder head and block gasket surfaces are clean, dry, and free of any

oil.    Installing Cylinder Head

1.      Put a new head gasket on cylinder block. Do not use sealant on gasket; install dry.

IMPORTANT: If cylinder head is lowered onto cylinder block and the head is not positioned correctly on locating dowels, remove cylinder head and install a new gasket. DO NOT try to reposition cylinder head on the same gasket again since the fire ring may possibly be damaged.

2.      Lower cylinder head evenly to correct position on block using appropriate lifting equipment. Make sure that head is positioned correctly over dowels and sits flat  on cylinder block top deck.

IMPORTANT: Only ASTM Grade 180 Flanged-Head cap screws marked “SPECIAL” (upper illustration) are recommended for use on 6081 engines. ALWAYS use NEW cap screws when installing cylinder head. Cap screws may be used only one time.

DO NOT use multi-viscosity oils to lubricate cap screws, SAE30 is recommended.

3.      Dip entire cap screw in clean SAE30 engine oil. Allow excess oil to drip off.

4.      Install correct length cap screws marked “SPECIAL” in proper locations shown and tighten using the TORQUE-TO-YIELD tightening procedure, described next in this group. See TORQUE-TO-YIELD

IMPORTANT: DO NOT use multi-viscosity oils to lubricate cap screws.

1.      Lubricate cap screws with clean SAE30 engine oil and install in their proper locations as outlined previously.

2.    Tighten cap screw No. 17 to 80 N•m (60 lb-ft), then sequentially start at cap screw No. 1 and proceed through cap screw No. 26, tightening all cap screws to specifications.

3.      Using an oil-proof pen, pencil, or marker, draw a line parallel to the crankshaft across the entire top of each cap screw head. This line will be used as a reference mark.

IMPORTANT: If a cap screw is accidentally tightened more than 90 in any one sequence, DO NOT loosen cap screw but make adjustments in the next tightening sequence.

4.  Sequentially (start at cap screw No. 1 and  proceed

through cap screw No. 26) turn each cap screw 90. Line on top of cap screw will be perpendicular to crankshaft.

5.      Again, sequentially (start at cap screw No. 1 and proceed through cap screw No. 26) turn each cap screw 90. Line on top of cap screw will now be parallel to crankshaft.

6.      Finally, sequentially (start at cap screw No. 1 and proceed through cap screw No. 26). Turn each cap screw 90, SO THAT LINE ON TOP OF CAP SCREW IS AS CLOSE AS POSSIBLE TO BEING PERPENDICULAR TO THE CRANKSHAFT. It is not necessary to obtain the final turn in one swing of the wrench. TOTAL AMOUNT OF TURN FROM STEPS 4, 5, AND 6 IS 270  5.
