u dont adjust the timing chain tensioner if there is slop or play in chain, u need to replace the chain . good idea to replace timing gears at same time while engine is pulled apart
Always replace the timing chain, sprockets and tensioner rails whenever you remove the head.
You cannot adjust the tensioner. It is automatic, and takes out the slack of a stretching/aging cam chain. Once the tensioner has fully extended, the only fix is to replace the chain and the part of the tensioner the chain rides on if it is worn.
The explorer has a timing chain, not a belt.
No, timing chain doesn't need replacing.
The 4.0 liter V6 engine in a 1994 Ford Explorer has a timing CHAIN
The timing chain tensioner bolt sticks out the back left side of the cylinder head. Take the timing chain cover off on the left side of the motor too see the inside to the chain tensioner.
A loose timing chain can only be repaired by replacing the timing chain . A loose timing belt means the belt is worn out or the tensioner is worn out. Replace worn parts.
The hanes manual tells you how to do it. I will be doing it this next weekend.
It's a load of a job,Remove radaitor, all hoses, pullys, belts,Valve covers, timing chain tensioner and guides. replace pump which is run off the timing chain. Make sure to line up the 3 marks on timing chain so you have correct timing. Reinstall tensioner and make sure it is recharged(all the way out) Turn engine by hand with a wrench to make sure chain is tight and timing is correct(Very important). Reassemble engine in reverse order. This would be a good time to replace the timing chain and tensioner if over 100,000 miles, good luck.
It depends. The explorer has a front timing chain and rear timing chain assembly. While the rear cassette/tensioner rarely fails, it is far more expensive and difficult to fix. If the front tensioner is the problem (which it commonly is), then the repair is quite simple. Either way, a dealership will charge an arm and a leg to repair. I have heard that fixing both can be as much as 2-3 thousand dollars.
It has a self tensioner, Most often you have to replace the chain it self if it is skipping time or is getting very loose.
It has a timing chain.
You never need to replace the timing chain if the engin use timing chain(not timing belt).
Timing CHAIN on the 4.0 liter V6 in a 1993 Ford Explorer
The 2.2 ecotec motor has a timing chain with oil pressure tensioner and chain guides.
The Pontiac Grand Prix has a Timing Chain with a spring loaded tensioner. The tensioner is know to wear, crack and then break. The timing chain and tensioner should be replaced at 100,000 miles. This is a pretty big job that can be done with the motor in the car. $$$ Ray
I am almost certain that the timing chain should last throught the life of the Explorer.
That ACTUALLY means that you probably didn't need to replace the timing chain in the first place. If you did it yourself, did you replace the tensioning rails? Check to see if they're worn. Note that one of the tensioning rails connects to a piston actuated tensioner assembly; if it isn't functioning properly the timing chain tension will not be maintained. Also, if the engine has low oil pressure, the tensioner will not function properly and you may end up with a loose timing chain.
chain. if you hear a clattering noise the timing chain and timing chain tensioner need to be replaced they are usually sold as a kit
To change a Vauxhall Corsa timing change you need to first remove the rocker cover, the alternator tensioner, heat shield, water pump, engine mount, and crankshaft pulley. Now that you have found the timing change, unscrew the timing chain guides, remove old chain, and replace with new chain.
