The timing system is complex, and severe engine damage will occur if mistakes are made; do not attempt this procedure unless highly experienced with this type of repair, and if unsure, consult an expert. Double-check all work to ensure everything is correct before starting the engine. Begin by disconnecting the cable from the negative battery terminal, then set the engine to the compression stroke for cylinder number 1. For 2015 and later CR-V models, remove the high-pressure fuel pump, followed by the valve cover and the timing chain cover. Rotate the crankshaft counterclockwise slightly to compress the chain tensioner, then install a 0.06 inch (1.5 mm) pin into the alignment holes to lock the tensioner, and rotate the crankshaft slightly clockwise to secure the pin. Remove the mounting bolts and the timing chain tensioner, then take out the upper timing chain guide from between the camshaft sprockets, followed by the camshaft timing chain guide and the tensioner arm, and finally remove the timing chain. Clean all parts with solvent and dry with compressed air if available, then inspect the chain tensioner for excessive wear or damage, ensuring to drain all oil if it is to be reused. Check the timing chain guides and the timing chain for excessive wear or damage, and inspect the crankshaft and camshaft sprockets for chipped or broken teeth or excessive wear, replacing any questionable components. Before starting the engine, carefully rotate the crankshaft by hand through at least two full revolutions; if any resistance is felt, stop immediately as there may be an issue with valve contact. Ensure the timing mark on the crankshaft sprocket is aligned with the pointer on the engine lock, and verify that the chain alignment dots on the VTC actuator and the exhaust camshaft sprocket are at the 12 o'clock position, with the TDC alignment marks on the sprockets opposite each other at the 9 and 3 o'clock positions. Install the timing chain, aligning the crankshaft sprocket with the colored link on the chain, then install the timing chain over the exhaust camshaft sprocket and the VTC actuator with the marks aligned. Install the camshaft timing chain guide and the tensioner arm, tightening the bolts to the specified torque, followed by the timing chain tensioner and the upper timing chain guide, also tightening the bolts to the specified torque. Remove the pin from the timing chain tensioner, slowly turn the crankshaft clockwise two revolutions, and recheck the timing marks and camshaft sprocket index marks for proper alignment. If the crankshaft binds or seems to hit something, do not force it, as this may indicate incorrect valve timing; in such a case, remove the chain and repeat the installation procedure. Finally, install the valve cover and the timing chain cover, reconnect the battery, and run the engine to check for leaks.

Install any removed sprockets with their keys and tighten the bolts.

Install a 0.05 inch (1.2 mm) pin into the alignment holes, then rotate the crankshaft slightly clockwise to secure the pin.

Inspect the chain tensioner, timing chain guides, timing chain, and crankshaft and camshaft sprockets for any signs of wear or damage.

Install the camshaft timing chain guide and tensioner arm, tightening the bolts to the specified torque, followed by the timing chain tensioner.

It comes as shown in the picture. Mounting bolt is sold separately.
