SOURCE: vt500 c ticking sound. Cam chain tensioners

You have a self adjusting cam chain tensioner. It is sold as an assembly. Take out the complete unit and replace it with a new one. The springs are not bad , the device that keeps the pressure on the tensioner is slipping causing a ticking sound.

SOURCE: when warm i notice a cam chain type noise. could

it can either be a worn tensioner or need for a valve adjustment. if you rev the engine and noise goes away, you need a new cam chain tensioner. if the noise remains or gets worse when you rev it up, you need a valve adjustment and should replac the tensioner anyway. 36,000 miles on the motor is definitely mileage for an adjustment if it's never had one.

Timming chain broke


place no 1 piston at TDC compression stroke. There are procedures for the timing of the balance shafts but if it is only the timing chain I will go to that
Align uniquely coloured chain link with intake camshaft sprocket timing mark-- INT--. ( this will be pointing at the 2 o'clock position)
install timing chain and sprocket as an assembly
align first matching coloured chain link crankshaft timing mark (5 o'clock position)
align the second matching coloured chain link with exhaust cam shaft timing mark--EXH ( at the 11 o'clock position
There is a special procedure to reset the balance tensioner and it is different to the timing chain procedure.

To reset cam shaft timing chain tensioner push piston fully and turn clockwise until locked
Once the tensioner has been compressed ensure the distance from end to end is 2.83 inches . If not repeat the resetting process
vehicles 30.000 miles the tensioner is released when the engine is first started . In vehicles over 30.000 miles manually release tensioner by tapping the plunger
Note cam shaft and crank shaft sprockets bolts MUST only be used once. If you want details on the balancer chain procedure then make a comment in the box
use tension wrench and a degree gauge
cam bolts are tensioned to 63 ft lbs + 30 degrees
crank shaft pulley is tensioned to 74 ft lbs + 75 degrees

2004 passat engine sounds like a deisel all of a sudden and has some engine lag


Hi, depending on engine fitted it is most likely the cam chain tensioner has collaped or failed. On a twin cam engine like a 1.8 t or a 32 valve V6 there is a chain driving a second chain in the rear of the cylinder head. These chains are tensioned by a oil pressure pressurized piston pushing on a bridge under the chain.

If it collapses, the chain/s become very loose and you will hear a loud clacking noise. It can also collapse due to low oil pressure.

VW is familiar with this problem and the repair involves first checking oil pressure, cold thro' warm. If it is around 85 to105 psi cold and 28 to 35 psi warm at idle, then this indicates tensioner piston is faulty or tensioner guide has broken off.

If oil presssure is good and engine is running synthetic oil...as it should ...then tensioneris suspect. I have also seen these engines with the screen under the tensioner partly blocked . If on removal of valve cover prooves tensioner has collapsed or guide shoe broken or warn then a new tensioner must be installed.

If oil pressure is too low at under 12 psi at warm idle then oil pump is worn and/or engine is worn. Also low oil pressure can be caused by fuel in the oil making it very thin.

If the screen under the tensioner is partly plugged up, then the oil pan must also be removed and cleaned out otherwise plugging will happen again.

To remove and install the tensioner a SST ( Special Service Tool.) is required to compresse the tensioner piston to allow it to be removed from under the cam chain and again compressing the new tensioner to be installed. Cams or chain do not need removing on this job.

Most import shops can handle this as long as they are equipped with the SST tensioner tool.

Can u adjust the timming chain on a yamaha xj 600 1998 model


The XJ600 has a self adjusting timing chain tensioner, although it's robust enough, like the previous post say's they can stick. To remove the adjuster look at the back of the engine on the cylinder head, the tensioner is there, two bolts hold it on one above and one below. to remove the tensioner there is a spring tensioner in the centre of the unit, undo this with care it hold the pressure spring in place on the plunger. Now remove the retaining bolts very carfully, equal turns on each bolts (do not take one out fully, leaving the other in place fully tight).
Once off the engine DO NOT ROTATE the engine. The tensioner should move freely, although there is a rachet system that locks it out, if it moves out freely then it's fine. To re-fit the tensioner release the tensioner make sure it's adjusted fully inwards and use a fresh gasket. The tensioner only firs one way, if it won't fit don't force it and it can be broken easily. Tighten both retaining bolts evenly and per the removal. Re-fit the tensioning spring and retaining bolt (do not over tighten) the plunger is self adjusting from here.

Installing cam chain on 09 CRF 450. It seems that I don't enough slack in the cam chain to fit it around the camshaft sprocket.


check that the new cam chain is roughly the same length as the old one, ensure that it is properly installed on the bottom (crank) sprocket, make sure that your tensioner is backed off fully, even after all of this you will still find that the chain seems too short, tip the cam to the left side of the engine & your chain should slip on..double check your cam timing with cam cap snugged down & tensioner released.

I need the step by step procedure for adjusting the cam chain on my 1982 650 maxim


Pop the cover off, turn the rotor until the C mark is aligned, Then loosen up the 12 mm nut that is on the 10 mm headed screw. Then loosen up the 10 mm headed screw. When the screw is loosened up it will take up slack and put spring pressure on the rod that puts pressure on the cam chain. Now that its taken up the slack tighten down the 10 mm headed stud and then the 12 mm locknut. That should take out all play in the cam chain tensioner. The cam chain tensioner is located under the carb boots from the engine to the carbs.
Hope this helps!
