Where is the camshaft located in an overhead cam engine?

Where is the camshaft located in an overhead cam engine?

ThyssenKrupp Presta Chemnitz GmbH / Wikimedia Commons In modern overhead-cam (OHC) engines, the camshaft is located in the cylinder head. Single OHC (SOHC) engines have one cam per bank, usually mounted between the valve stems. Rocker arms transmit SOHC movement to the valves.

Can a camshaft be removed from a cylinder head?

Warning: When removing the camshaft, you want to make sure that it does not fall, as it can damage the bearings in the cylinder head. Step 15: Remove the camshaft gear. Using your ratchet and socket, remove the center bolt on the camshaft gear and remove the gear from the camshaft.

How do you change the head gasket on a Hyundai?

Oil the new cylinder head bolts with clean motor oil. Lower the new gasket on to the engine block and align the dowel pins. Assure the number one cylinder of the engine is set to top dead center. Torque the new bolts in the correct tightening sequence.

What makes a dual overhead camshaft a DOHC?

­­Generally, engines with dual overhead camshafts (DOHC) are higher performance engines, they produce more power, and can run at higher spe­eds. The camshafts have the job of opening the valves that let air into and exhaust out of the engine. The camshaft uses rotating lobes, called cams, that push against the valves to open them.

How do you replace a Hyundai camshaft head?

Another option is to use a helicoil kit which comes with a drill bit and helicoil tap to suit. This means that the soft aluminum casting will need to be bored and tapped very precisely to accommodate the threaded insert which comes with the kit. In this process if an error is made it cannot be corrected and the head will have to be replaced.

Do you need to change timing on Hyundai camshafts?

If this is resorted a used head can be sourced from www.car-part.com. After replacing a Hyundai camshaft sensor on a V6 engine does the timing need to be readjusted? The Hyundai V6 engine has 2 cams one for each head located at the rear. After replacement nothing needs to be done to the timing which remains unaffected.

Where are the cams located on a Hyundai V6?

The Hyundai V6 engine has 2 cams one for each head located at the rear. After replacement nothing needs to be done to the timing which remains unaffected. However, the set codes will need to be cleared.

What’s the proper way to remove a cam head?

The proper way to handle removing the head involves using a foot long piece of firring strip to wedge the chain in its guides before loosening the camshaft gear. You’ll just have to re-time the engine is all. Which means to align the crank timing marks and the cam timing marks to spec, then re-install the timing chain.

How does the timing of the camshaft affect the engine?

Timing is important. Valves must open and close at specific intervals in relation to cylinder position. For example, as cylinder #1 is coming to top dead center (TDC) on the exhaust stroke, the camshaft is opening the intake valves and closing the exhaust valves.

How many camshafts does a 4 cylinder engine have?

An i4 (four-cylinder) SOHC engine has one camshaft, while a V6 or V8 SOHC engine has two. An i4 DOHC engine has two camshafts, while a V6 or V8 DOHC engine has four camshafts. Overhead-cam engines have three to five valves per cylinder, but usually two intake valves and two exhaust valves.

What can a broken camshaft do to a pushrod engine?

Broken Camshaft refers to catastrophic failure of the camshaft. This could be a manufacturing defect or be caused by the camshaft seizing. In pushrod engines, a broken camshaft could significantly damage connecting rods, cylinder block, pistons, or the crankshaft.

A short chain or gear set works well in this kind of application because the camshaft is located in the block just above the crankshaft. In overhead cam (OHC) engines, the camshaft is located high in the cylinder head far from the crankshaft.

Where are the cam marks on a triumph?

To put it simply you always us the cam marks which line up with the wood ruff key. For this article we will assume the bike is stock and not modified with extra gear stamping.

How many gears does a Chevy 262 V6 use?

For example, Chevy has used three different timing gears for the 262 V6 since it first appeared in 1985. The flat tappet engines use a p/n 340235 gear, the non-balancer, roller cam engines use a p/n 12552128 gear, and the balancer engines use a p/n 10144121 gear. None of these gears are interchangeable.

What are the timing gears on a Chevy LT1?

Chevy has also used two different timing gears on its LT1 V8 engines. The earlier 1992-’95 LT1 engines with aluminum heads use a p/n 10128349 cam drive gear with a small hole with 16 splines in the center. On 1995 and later LT1s, a different gear (p/n 10206039) with a larger, unsplined center hole is used.
