Handle the parts in accordance with your WarrantyBulletin on warranty parts handling.Attach. (1-Rework Procedure)Rework Procedure
For Vee engines it is not necessary to removethe main bearing caps to replace the main studs. There is enough clearancebetween the main cap and oil pan to allow removing and replacing the studsone at a time with the main cap in place. If replacing several studs alwaysstart at the front of the engine and work towards the rear. On Vee enginesthe crosstie bolts can remain torqued and only the actual stud nut needsto be removed following the procedure for main removal called out in theDisassembly and Assembly Manual.On Inline engines the cap will have to be droppedcompletely out of the way to allow clearance for the stud removal. Againthe work should begin at the front main and progress rearward. During reassemblypay particular attention to the torque sequence.
Lubricate Stud threads with engine oil.
Torque the 1W0127 Stud to 100 +/- 20 Nm (74 +/-15 lb-ft).
Install the main cap with the part number towardsthe front of the block.
Coat all nuts, bolts and washers with engine oil.
Install all nuts and bolts hand tight.
Torque the right side (tab slot side) crosstiebolt to 215 +/- 40 Nm (158 +/- 30 lb-ft.).
Using the Hydraulic tensioner, tension each stud67,000 +/- 200 Kpa and Hand tighten the nut.
Release tension and repeat previous step.
Tighten the left side (side opposite the tab slot)crosstie bolt to 215 +/- 15 Nm (74 +/- lb-ft).
Torque the right side (tab slot side) crosstiebolt to 1825 +/- 175 Nm (1346 +/- 130 lb-ft.).
Tighten the left side (side opposite the tab slot)crosstie bolt to 1825 +/- 175 Nm (1346 +/- 130 lb-ft.).
