How do you lock down the timing belt?
Some manufacturers make a slot on the back side of the cam or a hole on the top of a cam bearing cap to slide in a punch, screwdriver or flat piece of steel through the back to lock down the cams after everything has been lined up at TDC No.1.
Where are the dimples on the timing belt?
Put the transmission in neutral. Rotate the engine (via the crank bolt) clockwise until the dimples on the crank sprockets align with the dimples on the rear timing belt covers, and the line on crank pulley aligns with 0 degrees. The sprocket marks will not align perfectly; these dimples are for reference at this step only.
How often do timing belts need to be replaced?
While timing belts have been steadily getting replaced by chains due to their longer service life, belt manufacturers have made strides to improve their belt life to more than 100,000 miles, in some cases. Even though belts will not last as long as a chain, they are quieter and often easier to line up correctly with the cam and crank locked down.
What’s the best way to remove a camshaft sprocket?
Use a camshaft sprocket holding tool to hold the sprocket in place. Then, remove the sprocket bolt using a long ratchet and socket or a breaker bar. Note: If the camshaft sprocket is not held properly, the camshaft may spin causing, engine damage.
How can I change the timing belt on my car?
Remove all of the parts that might be blocking your access to the engine timing belt cover. Remove the cover and inspect the materials and condition of the belt. Replace the belt with the recommended part number. Don’t forget to also replace the water pump, tensioners and pulleys while changing the belt iteself.
Do you need to replace the timing belt on a water pump?
Water pump: The water pump is generally driven by the timing belt and needs to be removed for the switch. The part is inexpensive and might as well be upgraded while it is already in the shop. The cost of labor far outweighs the price of the water pump itself.
When to replace pulleys on a timing belt?
Pulleys and Tensioner: These parts should be replaced with the timing belt because if they fails, the same damage as a timing belt failure can occur. They provide the force required to keep the belt tight and operating without any slack, also preventing it from falling off of the track.
How to get my timing back correct after?
3. Install the timing belt (4) starting at the crankshaft sprocket (10) going in a counterclockwise direction. Install the belt around the last sprocket and maintain tension on the belt as it is positioned around the tensioner pulley (11).
Why do you need to lock down the timing belt?
Even though belts will not last as long as a chain, they are quieter and often easier to line up correctly with the cam and crank locked down. Anytime the belt is removed, the cam and crank need to be aligned to TDC No.1, which is where the marks on the crankshaft pulley line up with the pointer on the front cover.
Where to install timing belt on Dodge Journey?
Install the timing belt (4) starting at the crankshaft sprocket (10) going in a counterclockwise direction. Install the belt around the last sprocket and maintain tension on the belt as it is positioned around the tensioner pulley (11).
What should I do if my timing belt broke?
Aligning the camshaft if your timing belt broke is something you need to do very specifically or you risk destroying your entire engine. Align the camshaft if your timing belt broke with help from an experienced automotive professional in this free video clip.

How to get your oil pump timing back?
CAUTION: If camshafts have moved from the timing marks, always rotate camshaft towards the direction nearest to the timing marks (DO NOT TURN CAMSHAFTS A FULL REVOLUTION OR DAMAGE to valves and/or pistons could result). TIMING GEAR ALIGNMENT 1. Align the crankshaft sprocket (10) with the TDC mark (9) on the oil pump cover.

Why is advancing cam timing better for low rpm?
This can allow an engine to exceed 100% volumetric efficiency, if even by a small amount. Advancing overall cam timing: Advancing overall cam timing is better for low-RPM power. This is because the valves are closing a little sooner.
What happens when you install a larger camshaft?
When a larger duration camshaft is being installed, unless the lobe centerlines have been changed, the overlap will be increased. If installing larger camshafts in a turbo application, advancing the exhaust and retarding the intake will reduce the inherent increase in overlap caused by upgrading to a larger profile.
What’s the sequence of events in a camshaft?
Looking at a camshaft, the sequence would be as follows: The exhaust lobe pushes open the exhaust valve and the piston comes up to push the exhaust out, then starts to close. The intake starts to open, just as the exhaust is closing, piston goes down, and the intake valve closes.
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.
Where can I find the timing chain procedure?
You can also find step-by-step instructions at www.Autozone.com, setting up an account, and using their repair guides. I just checked, and your ’87 2.4L Z24 engine timing chain procedure is in there. It is slightly involved, so I don’t want to try and retype them here and make a mistake.
Where does the TDC occur on a crank?
Crank TDC is ambiguous, as it occurs at the top of the compression stroke, and the top of the exhaust stroke. You want the ignition to be timed to fire at the top of the compression stroke. The shop manual should explain how to insure you are sync’d to the correct phase.
