How do you change cam chain on cb1000 - Cars & Trucks

here we don't have this model. i can suggest check wiring from cam sensor to ecu . if ok then check timing , is it this model use timing chain if yes then it may be timing chain long already. you have to change timing chain.

Hi. It could be the cam adjuster or the Timing chain stretched.

If you do regular maintenance on the engine and do regular oil changes there will be no regulatory period for the chain to be replaced unless it becomes noisy and is affecting the performance of the engine.

One other thing you should check judging it being a 1993. Check the fuel pump pressure for adequate fuel supply to all those new components. If you don't get the correct pressure you will experience back firing and inconsistency in your engine performance.

yes the silverado's have timing chains, just about all v6's and v8's have timing chains, and timing chains should not be serviced, unless you are having problems with a timing chain guide or timing chain tensioner

Same as any other v-8 dis-assemble the front of the engine to get to the timing cover. Loosen the oil pan bolts to allow the timing cover to be slipped out. unbolt and remove the timing cover. Turn the engine over by hand until the dot on the crankshaft gear( the small one) is at the top 12 oclock position, and the dot on the cam gear(large gear) is at the bottom 6 oclock position remove the old cam gear and old chain. Install new gear and chain with the marks in the same places. Re assemble engine. DO NOT be tempted to just put in a new chain, replace the chain and cam gear as a set, wear on the cam gear will cause the chain to be slack, which in turn causes the cam timing to be late.

If it's anything like the six cylinder engines from Audi, which I'm very familiar with, and from what I remember of the V8, you have a timing belt that drives the water pump, crank, and exhaust cams, and also includes a tensioner and an idler roller. The timing chains come into play in the cylinder heads. What Audi did was to only drive the exhaust cams off of the crank, using the timing belt, and inside each cylinder head there is a timing chain assembly that is used to drive the intake cams off the exhaust cams. On a periodic service (like the timing service) you only need to do the timing belt. The timing chains are only replaced if the tensioners fail - you'll know this by a diesel-like clatter from the cylinder heads. Failure of the chain drive assemblies is very rare, which is good because they're incredibly expensive (on the V6 engines they're upwards of $700 each). If you're doing this job because it's due based on mileage, don't touch the timing chains in the cylinder heads - only change the timing belt, tensioner roller, relay arm, hydraulic tensioner, idler pulley, water pump, and serpentine belt. You can leave the chains alone.

These are chain driven. The only issue I have seen with these are the chain tensioners breaking. Generaly with chain driven engines, the chain will last the life of the vehicle, unless something like the tensioner or guide brakes. If it does break repairs can be fairly expensive.

That is an extremely difficult engine to work on regarding the chain. There is on thing you can try is to change the tensioner for the rear chain. You can access it from the passenger wheel well, it looks like a big nut from the outside. Get a new tensioner screw and replace it. if that dosent work you will have to remove either the engine or the transmission to gain access to the chain itself.
