Camshafts

Installation

All vehicles

1. NOTE: If new parts are installed, transfer the reference marks made during disassembly to the new parts.

If necessary, position the camshaft in a soft-jawed vise and install the camshaft phaser and sprocket and the bolt.
^ Align the reference marks on the camshaft phaser and sprocket and the camshaft. Tighten the bolt to 72 Nm (53 lb-ft).





2. CAUTION: Install the camshafts with the alignment slots in the camshafts lined up so the Camshaft Alignment Plate can be installed without rotating the camshafts. Make sure the lobes on the No. 1 cylinder are in the same position as noted in the removal procedure. Rotating the camshafts when the timing chain is removed, or installing the camshafts 180 degrees out of position can cause severe damage to the valves and pistons.

NOTE: Lubricate the camshaft journals and bearing caps with clean engine oil.

Install the camshafts and bearing caps in their original location and orientation. Tighten the bearing caps in the sequence shown in 3 stages:
^ Stage 1: Tighten the camshaft bearing cap bolts until finger tight.
^ Stage 2: Tighten to 7 Nm (62 lb-inch).
^ Stage 3: Tighten to 16 Nm (12 lb-ft).





3. Install the special tool.





4. Install the timing chain on the intake camshaft drive gear.





5. NOTE: The timing chain must be correctly engaged on the teeth of the crankshaft timing sprocket and the intake camshaft drive gear in order to install the exhaust camshaft drive gear onto the exhaust camshaft.

Position the exhaust camshaft drive gear in the timing chain and install the gear and bolt on the exhaust camshaft.
^ Hand-tighten the bolt.





6. NOTE: Releasing the tensioner arm will remove the slack from the timing chain.

Remove the M6 x 30 mm (1.18 inch) bolt from the upper front cover timing hole to release the tensioner arm.

7. CAUTION: The special tool 303-465 is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.

Using the flats on the camshaft to prevent camshaft rotation, tighten the exhaust camshaft drive gear bolt to 72 Nm (53 lb-ft).





8. Remove the special tool.





9. Remove the 6 mm (0.23 inch) x 18 mm (0.7 inch) bolt.





10. Remove the special tool.





11. Install the upper timing hole plug in the engine front cover.
^ Tighten to 10 Nm (89 lb-inch).





12. Apply silicone gasket and sealant to the threads of the lower timing hole plug.
^ Install the lower timing hole plug in the engine front cover.
^ Tighten to 12 Nm (9 lb-ft).





13. Install the engine plug bolt.
^ Tighten to 20 Nm (15 lb-ft).





Automatic transaxle vehicles
14. Install the RH halfshaft and the 2 halfshaft carrier bearing bracket bolts.
^ Tighten to 40 Nm (30 lb-ft).

All vehicles
15. If equipped, install the underbody cover and the 7 screws.
