When do you replace the timing chain on a Honda?

According to Honda and many other car manufacturers, the timing chain doesn’t have a regular replacement interval. They are supposed to last beyond the 300,000 km (186,000 mi) mark. Okay, so we can drive our car guilt-free until we reach a mileage where it falls apart anyway. Not so fast.

Where is the TDC mark on the K series timing chain?

Now crank the engine clockwise by turning the crankshaft pulley with a ratchet until the TDC marks of both cam gears line up and the marker on the crankshaft pulley points to the arrow on the chaincase. Lined up TDC mark on the crankshaft pulley. In our case, the culprit of the malfunctioning VTEC system was found.

What kind of timing chain do I need for an OHC engine?

OHC engines can have either a single camshaft (SOHC) per head or one for the intake and another for the exhaust valves (DOHC). Timing chain kits for engines with overhead cams differ from engine to engine. The design does require extra attention to detail and often quite a bit more work and more parts to install than the cam-in-block design.

How do you line up the timing marks on an engine?

Consult the engine repair manual, since these will differ by model. Line up the timing marks. Using a wrench or socket on the crankshaft bolt rotate the engine until the timing mark on the crankshaft pulley is aligned with the 0° mark on the timing scale.

What are the bright links on a timing chain?

Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.

What’s the best way to remove a timing chain?

Put the bolt partially back in the bolt hole and use a harmonic balancer removal tool. The tool should not be a jaw type tool, but instead should apply all of the removal force to the center of the assembly. This protects the rubber ring in the harmonic balancer. Remove the timing chain cover.

How do you remove a timing belt cover?

On most timing chain cars and many timing belt cars, the water pump has to come off to get access to all of the bolts or to get enough clearance to get the cover off. Remove the bolts holding it down and gently pry it off. Step 6: Remove the drive pulley.

How can I keep track of my timing cover?

The best way to keep track of them is to draw a diagram of the timing cover on a piece of cardboard and push the bolts into the cardboard as you remove them. Some engines will have a few bolts coming up through the oil sump and down through the cylinder head to the timing cover.

Where is the timing chain on a water pump?

The water pump is attached to an idler sprocket of the left bank of the timing chain. To replace the water pump, both chains need to be removed. This pump has been known to go 200,000 miles or more.

What happens when you remove a water pump sprocket?

If you don’t use this tool, you will damage the chain tensioner. When you remove the pump without fixing the water pump sprocket, the tensioner could ratchet out and cause the tension to increase to the point where the chain makes noise and the water pump fails prematurely.

Where does RTV go after removing timing cover?

But be CAREFUL, after removing TC, you will see a small vertical rectangle on the engine block about 1.25 inches inward from each side, about 1/4-3/16ths wide and ~3/8ths tall. These are for oil return from timing chain and spillage from oil pump back to the oil pan, do not put RTV across bottom of these! RTV basically goes toward outside of those.

How do you remove a V-belt from a water pump?

Some tensioners can be compressed with simple hand tools such as a wrench, and others may require a special tool. V-belts can be removed by adjusting the position of one of their pulleys to release tension. Remove the belt. Once tension is released, the belt should slide off of the other pulleys easily. Remove the heater hoses from the water pump.

How do you install a new crankshaft pump?

When the new pump is installed, you will need to reinstall the tensioner. Turn the crankshaft pulley approximately 20° counterclockwise so that the timing chain on the timing chain tensioner side is loose, and then install the tensioner. Don’t forget to remove the pin holding in the tensioner, and check the timing before you install the covers.

How long does it take to turn a Nissan water pump?

The VQ35-series of engines can be found in 2001-current Nissans and Infinitis. The pump is nestled in the engine block and is turned by the timing chain. Book time on this job can range from two to three hours depending on the model and layout. There are no shortcuts.

How do you remove a water pump from an engine?
