Camshaft

Fix the camshaft with a wrench, loosen the bolt, remove the bearing cap bolts in the specified sequence, then raise and remove the camshaft along with the sprocket bolt and disconnect the camshaft timing sprocket from the timing chain.

Remove the V-bank cover sub-assembly, front suspension upper brace center, air cleaner assembly with hose, intake air surge tank, spark plug, cylinder head cover sub-assembly, front wheel RH, front fender apron seal RH, V (cooler compressor to crankshaft pulley) belt No.1, vane pump V belt, engine moving control rod, engine mounting stay No.2 RH, generator bracket No.2, crankshaft pulley, timing belt No.1 cover, timing belt No.2 cover, engine mounting bracket RH, timing belt guide No.2, timing belt, and timing belt idler sub-assembly No.2.

Check the alignment of the paint marks, install chain tensioner assembly No.1, cylinder head cover sub-assembly, connect the engine wire, install ignition coil assembly (torque: 9.0 Nm (92 kgf-cm, 80 inch lbs.)), install spark plug (torque: 19 Nm (194 kgf-cm, 14 ft. lbs.)), install front wheel RH, and check for engine oil leaks.

Fix the camshaft with a wrench and tighten the sprocket bolt to 54 Nm (551 kgf-cm, 40 ft. lbs.), ensuring not to damage the valve lifter, check the alignment of the paint marks, install chain tensioner assy No.1, cylinder head cover sub-assy, connect the engine wire, install ignition coil assy (torque: 9.0 Nm (92 kgf-cm, 80 inch lbs.)), install spark plug (torque: 19 Nm (194 kgf-cm, 14 ft. lbs.)), install front wheel RH, and check for engine oil leaks.

Loosen the bearing cap bolts in the specified sequence, remove the camshaft, and tie the timing chain with a string, ensuring nothing drops inside the timing chain cover.

Raise the No. 2 camshaft and remove it along with the sprocket bolt and camshaft timing sprocket.

Remove the 2 nuts, tensioner, and gasket, ensuring not to revolve the crankshaft without the tensioner.

Disconnect the engine wire harness clamp and remove the bolts, 2 nuts, cylinder head cover, and gasket.

Remove the 2 nuts, tensioner, and gasket, and note not to revolve the crankshaft without the tensioner.

Align the painted mark with the timing mark of the camshaft timing sprocket, temporarily tighten the sprocket bolt, install the bearing caps and bolts, and tighten the sprocket bolt to 54 Nm (551 kgf-cm, 40 ft. lbs.) while ensuring not to damage the valve lifter.

Install the camshaft sub-gear and timing gear assembly, applying engine oil to the nut and tightening the lock nut to 150 Nm (1,530 kgf-cm, 111 ft. lbs.).

Ensure the camshaft is kept level during removal to prevent damage.

Turn the crankshaft pulley to align its groove with the timing mark 0 of the timing chain cover, ensuring the timing marks of the camshaft timing gear and sprocket align with the bearing caps, and place paint marks on the timing chain.

Align the painted mark of the chain with the timing mark of the camshaft timing sprocket, temporarily tighten the sprocket bolt, and install the bearing caps.
