Remove the bolt attaching the Air Control Solenoid to the top of the Waterpump. The problem with a belt though, is that if it is kept in service too long, it can break. By taking the financial hit early you can avoid major engine damage which can cost thousands of dollars to repair. Tap the oil seal out of the front of the oil pump and install the new one. So now, what do I do, the large gear will only fit on one way. Remove the crossover air tube that goes between the airbox and the intake.
You may find the need to replace your timing chain at some point; however with the right tools, a service manual and some mechanical know-how, you can do it yourself. Like the lower timing chain gear, the dampener also features a slot that slides over the metal pin on the tip of the crankshaft. Reinstall the timing cover with 6 pound-feet of torque to each bolt. Second question, when I removed the small gear I noticed there was a concave ring around the shaft about where the front of the gear would have been, is there something that goes in there to hold the gear on? There are lots of sharp, hard things for you to cut and bruise your knuckles on over there if your breaker bar were to slip… This is a tedious, slow, messy process since the steering gear fluid line is soaking your tools with dripping power steering fluid. Belts are quieter, but that is not part of this question. These components are connected with rubber hoses attached with clamps. Each hose connects to the water pump with a band clamp secured with a screw.
If the distributor was removed, install it now, with the rotor pointing toward the 6 plug wire location. Align the seal in the opening and then using a soft mallet tap the seal into place in the timing chain cover, alternating as you go until the seal has fully seated into the cover. You may need to use a gear puller to break it loose. There is a ground wire that goes to the block for now leave this attached and set the alternator in the bottom of the engine compartment The alternator bracket bolt is one of the bigger 14mm Timing chain cover bolts. The crankshaft turns to move pistons up and down inside the cylinders. Three bolts possibly another if it has a brace. The timing chain on your vehicle is the connection between the crankshaft and camshaft.
However, according to another leading timing component supplier, over the past 20 years belt applications have been fading out. Says another technical expert, the biggest change in timing sprockets has been a move from machined cast iron to sintered powdered metal. Clean the timing chain cover. Chains are more durable than belts and typically have a longer service life. When the engine runs uneven at low rpms, the gears can rattle. As engines continue to be physically downsized, belts are seen as the more cost-effective choice by many manufacturers. Now, using your trusty chisel and hammer, drive the chisel in between the steel bar and the timing gear.
The shafts are gear driven off the cam, and there are two different gear sets, one with wide teeth and one with narrow teeth. This distroys the aluminium gears fast, especially the straight cut ones. At idle, the time interval between valve openings for each cylinder is about a fifth of a second. It's quite a job for no purpose if the timing is correct, so try this last. Slide the camshaft gear onto the cam, aligning the hole in the gear with the dowel in the front of the cam.
When a belt breaks, the valvetrain is no longer kept in time with the crank piston and rod assembly, so usually the pistons hit 1 or more valves, resulting in lots of damage. Drain the antifreeze from the radiator by removing the petcock plug at the base of the radiator with a wrench. Often, if the timing chain is worn the engine may feel sluggish, low on power or have troubles starting. Install the timing chain cover and the water pump. The engine may continue to run but will experience a loss of performance because of the altered valve timing. Starts very good and quick when you pump a little gas but I know it could start better.
Article Summary To change a timing chain, remove the radiator cap, drain the coolant out, and remove the radiator hoses. This is the weakest point on the gear. Break loose the bolt holding the distributor drive gear and cam gear on. All other aspects of doing this work are very straight forward and relatively simple. Third question, I hadn't thought about replacing the Oil Seal on the chain case cover, should I? When this happens, ignition timing will be off because the spark plugs are not being fired in time, or in order. I set it on 6 with the dots together in the middle.
When you step up to a 5. Bolt the cam gear and distributor drive gear down to prevent it from popping off. Right in front of the cam gear, directly below where the distributor drive gear was is a small pool of oil hiding the bolt. If the mileage is not known, replace the belt. When I change my cam, heads and intake, the timing chain will be replaced also. Since the eccentric has already been removed, simply pull the upper timing chain gear off of the camshaft. Replacing the timing chain is a complicated job, and the labor costs can be quite high.
Remove the famed hidden timing chain cover bolt that is not mentioned in any shop manuals even the Toyota shop manual. Scrape and clean the gasket surfaces of each. Contain and dispose of coolant properly. This is critical for maximum performance and to prevent engine damage. Disconnect the bottom radiator hose, the heater hose and the intake manifold hose from the water pump. Modifying your puller to this configuration will greatly ease the job, and will keep you from having to pull the fan, shroud, and radiator out of the car.
Line up the rotor to where it was pointing when you removed it and set the distributor to the mark you made before removal, this will get it close to the correct timing. They last much shorter than the chain. Allow yourself a day for a leisurely pace of wrenching and beer drinking. This will secure the hose to the pump. As for my situation: I have a low-mileage bike, but I am all for replacing known weak links before they become problems. The rotor should end up about centered on the 1 cylinder contact inside the distributor cap. The last two engines I have put together I have had to purchase 2 sets of timing chains to get 1 that worked - and these were not cheap junk sets either.
