1/4 MAX
The factory timing chains have a lot more slack than the aftermarket chains.
Not much but there will be a little.
The timing chain follower is worn causing a slack condition in the chain. the chain oscillates and so does the timing.
Check for excessive slack in the timing chain.
replace the chain and gears
The 350 Chevy does not have a belt, it has a chain. Slack in the chain is normal as long as it is not excessive. A better determining factor on when to replace the chain, is the condition of the gears and if the chain is noisy.
check timing. timing advance. or slack in timing chain/belt
There is no set mileage to change the timing chain. Chains will usually last the life of the engine. The usual symptoms of a chain going bad are that the engine rattles when you first start it (chain flapping around) and lacks power(slack chain causing camshaft timing to drift around unpredictably). Replacing a chain can cost from $500-$700 so just rest easy, and unless you hear it or notice poor performance it is fine.
Over time the tensioner may have loosened, in addition timing chains can stretch slightly and this can throw off the timing
To install a timing chain on a 125cc four-wheeler, first ensure the engine is at top dead center (TDC) on the compression stroke. Remove any necessary covers to access the timing chain and sprockets. Align the timing marks on the crankshaft and camshaft, then place the new timing chain around the sprockets, ensuring it fits snugly without slack. Finally, reassemble any removed components and check for proper alignment before starting the engine.
It has a chain, and normally they are good for over 100,000 miles. The usual symptoms are that the engine rattles when you first start it (chain flapping around) and lacks power (slack chain causing camshaft timing to drift around unpredictably), the engine will not stay in time, or is performing poorly, it may need a new chain.
A 2000 Skoda Felicia 1.3 mpi has a timing chain. Not a timing belt. A timing chain. So buying a used felicia and not replacing it is not actually risky, as with a car with a timing belt. The chain of course will also develope 'slack', so it is a good idea to change it after so many klms, and/or if it as gotten too noisy. The possibility of the chain breaking is very very very slim. It WILL develope some slack though, and might jump a tooth, worsening performance and fuel economy. Parts are cheap for the felicia.
