Connecting the timing gears is a single chain. The purpose of the gears and the chain is to ensure that the camshaft and the crankshaft rotate in unison. The timing gears are fairly durable, but the teeth on the gears can become worn. More frequently, the chain itself stretches. Fortunately, installing a replacement chain and gears is relatively straightforward. Cyberlink powerdirector 8 serial download cracked software. This is a basic question and I feel stupid for askin but here goes. When installing a timing set on a sbc you put the dot on the crank gear at 12 oclock and the cam gear at 6 oclock right. Timing is everything and it is especially important when building an engine. Al talks about installing a timing. 7: Remove the camshaft gear bolts (arrows) and remove the camshaft gear with the chain These engines are equipped with a timing chain. To replace the chain, remove the radiator core, waterpump, harmonic balancer, and the crankcase front cover. This will allow access to the timing chain. Crank the engine until the matchmarks punched on both sprockets are closest to one another and in line between the shaft centers. Then, take out the three bolts that hold the camshaft gear to the camshaft. This gear is a light press fit on the camshaft and will come off readily. It is located by a dowel. The chain comes off with the camshaft gear. A gear puller will be required to remove the crankshaft gear. Without disturbing the position of the engine, mount the new crank gear on the shaft, then mount the chain over the camshaft gear. Arrange the camshaft gear in such a way that the timing marks will line up between the shaft centers and the camshaft locating dowel will enter the dowel hole in the cam sprocket. Position the hanging part of the chain under the crankshaft gear, then place the cam sprocket, with its chain mounted over it, in position on the front of the camshaft and pull up with the three bolts that hold it to the camshaft. After the gears are in place, turn the engine two full revolutions to make certain that the timing marks are in correct alignment between the shaft centers. ![]() 231 cid Engine See Figure 8. By Jeffrey Smith - November 26, 2014 This article applies to the Ford F-250 and F-350 Super Duty (2005-2014). Your F-250's timing chain controls when the valves open and close by spinning the camshafts. When the timing chain becomes too loose or the tensioner breaks, the most hopeful outcome is a stall or an engine that won't start. The worst case scenario is having a valve hit a piston. A broken valve in the combustion chamber will completely destroy your engine. Avoid this by anticipating the timing chain's failure. There are subtle signs that the timing chain is going bad that mostly occur during start up in the form of a rattle or knocking and pinging sound. If you hear such noises on start up, you should probably investigate your timing chain tensioners and guides. Learn how to do so with our guide below. Materials Needed • 7/16 wrench • Flat head screwdrivers • Impact wrench (optional) • Pry bar • Timing chain repair kit (timing chain, guides) • Harmonic balancer puller Step 1 - Disconnect battery Disconnect the negative (black) terminal from the battery first. Then, disconnect the positive (red) battery cable. Step 2 - Drain the radiator The radiator hoses will need to be removed in order to access the timing chain. Instead of just yanking the lower hoses and letting coolant flood out everywhere, drain your radiator via the petcock valve. It should be a white, plastic bolt (Figure 1) located on the bottom of the radiator. You have two options for draining the fluid. You could unscrew the petcock and let the fluid drain out into a bucket without a hose, which could be messy; alternatively, you could connect a 3/8' tube to the valve and drain the fluid into a bucket (Figure 2). Locate this white nut on the bottom of your radiator. Unscrewing it will cause fluid to drain. Drain radiator fluid into a bucket or used coolant bottle. Pro Tip Radiator fluid smells sweet like candy to pets, and it is too hard for them to resist this deadly poison. If you have pets be sure to clean up any spills and properly dispose of the old fluid. Step 3 - Remove the fan shroud and fan The fan shroud (if you have one) takes up vital space and needs to be removed. The fan itself ought to be removed as well. This will likely take a 7/16' wrench. The shroud is highlighted in the diagram below, and its location and mounting points are plainly visible when looking under the hood. Remove the fan shroud, highlighted in red. Step 4 - Remove the valve covers You will need to remove the valve cover in order to access the timing chain. Blast the cover with compressed air first so that you don't accidentally knock dirt and muck into your valvetrain. You will need to remove the ignition coils and any other components attached to the valve covers that will obstruct its removal. For the driver's side valve cover, you will need to: • Remove the air intake. • Remove the ignition coils. • Unbolt the oil dipstick tube from the block and move it out of the way. • Unbolt the power steering reservoirs and move them to the side. • Remove the PCV tube. • Disconnect vacuum hoses connecting to the valve cover. • Disconnect all brackets attached to valve cover and all wiring harnesses and electrical connectors. For the passenger side valve cover, you will need to. Related Articles: • - Ford-Trucks.com • - Ford-Trucks.com • Figure 4. The serpentine belt tensioner is highlighted above. It looks and operates the same way in most Ford V8s and V6s, including diesels. You will not find it on the new 3.7-liter V6, the 3.5-liter EcoBoost, or the 5-liter 'Coyote.' Rotate this arm clockwise to relieve tension on the serpentine belt. Step 6 - Remove the alternator and bracket Remove the alternator and bracket. Be sure to note the wiring and where they go. Remove the alternator and bracket. Pro Tip Be sure to note where the wiring to the alternator goes so you don't fry it and the battery when you re-install it.

These are held on with clamps that will require pliers to remove. There are two that must be removed. The first connects to the top of the radiator from the water pump. Disconnect this one first as it'll be the easiest to get to. Remove it from the radiator and the waterpump. The next step might be easier if the lower radiator hose is removed, too. Remove upper radiator hose from radiator. Remove lower hose (highlighted above) if needed. Step 8 - Remove the crank shaft pulley The crankshaft pulley must come off, which is the most difficult step in the job. To get the bolt out, you'll need to stop the pulley from spinning. You will need a pry bar or something similar to jam the pulley, otherwise the pulley will spin when you try and remove its center bolt. Be warned: this bolt is a bear. If you happen to have an impact wrench, the job will be easier and you may not need any extra help. Unbolt crankshaft pulley bolt to remove crankshaft pulley. 1 -- Accessory belt 2 -- Crankshaft pulley bolt 3 -- Crankshaft pulley bolt washer 4 -- Crankshaft pulley 5 -- Crankshaft front seal • Figure 10. Crankshaft pulley held tight with pry bar. Step 9 - Remove crankshaft front seal When you get the pulley off, you will also need to remove the crank shaft front seal. This should be replaced with a new one to avoid the potential of an oil leak. Pulling off the seal can be tricky. The key is to pull it out without scoring or otherwise damaging the surrounding hardware. While a flathead screwdriver could will work in a pinch, it could also do damage by accident. Just be careful not to let the let the screwdriver scrape or hit anything other than the seal. Alternatively, there's a special tool just for this task. Crankshaft seal and special tool. Featured Video: Front Main Seal Replacement. Step 10 - Camshaft position sensors You'll need to remove the electrical connectors first, then the bolt that holds the sensors on. Set those aside and consider purchasing replacement O-rings for them. Even a small nick in one can cause oil leakage. • • Figure 12. Camshaft position sensor locations on different engines. Step 11 - Remove the front engine cover There are several bolts and dowels keeping this in place. When the front cover is removed, you'll have access to the timing chain for removal and replacement. Removing the front engine cover. Pro Tip Do not use metal scrapers, wire brushes, power abrasive discs, or other abrasive means to clean the sealing surfaces.

These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant. How To Install Timing Gears On Sbcglobal EmailStep 12 - Replace chain and guides Now, your timing chain and guides will be exposed. Rotate the crankshaft so that the number 1 cylinder is at top dead center. The timing chains have markings on them to make sure they're correctly aligned. On the crank shaft, there's a black mark that should be pointing straight up. How To Install Timing Gears On Sbcglobal.netAlso, the link on the chain nearest to the bumper should have a colored link in the 6 o'clock position. The camshaft gears have marks on them, too. The timing chain will have two colored links that should straddle that mark. Remove the bolts holding the chain tensioners and chain guides to remove the chain. Replace guides and tensioners with new ones and a new chain, if necessary.
