Main bearing cap bolt tightening sequence - 4E-FE and 4A-FE Non-VVT-i engines

A Rotate the thrustwasher into position with the oil grooves facing outwards

Apply a 2 mm wide bead of sealant to the main bearing ladder

Non-VVT-i engines

B Fit the thrustwasher in the number three cap with the oil grooves facing out

8 Make sure the crankshaft journals are clean, then lay the crankshaft back in place in the block.

Clean the faces of the bearings in the caps, then apply lubricant to them. Install the caps in their respective positions with the arrows pointing toward the front of the engine. The tanged lower thrustwashers should be placed on the caps with their grooves OUT and the tangs fitting into the cap slots (see illustrations).

9 Apply a light coat of oil to the bolt threads and the undersides of the bolt heads, then install them. Tighten all main bearing cap bolts to the correct torque, following the recommended sequence (see illustration).

10 Make sure the crankshaft journals are clean, then lay the crankshaft back in place in the block. Clean the faces of the bearings in the main bearing ladder, the apply lubricant to them.

11 Apply a 2 mm wide bead of sealant

(Toyota No 08826-00080) to the main bearing ladder (see illustration). Install the main bearing ladder within 3 minutes or the sealant will harden.

12 Refit the main bearing ladder bolts, and tighten the inner row of 10 bolts in sequence to the Stage 1 torque setting, followed by the Stage 2 angle-tightening setting (see illustration). Tighten the remaining mainbearing ladder bolts to the specified torque.
