Timing Belt Manual tension clicking

Noah1798 · Post by **Noah1798** » 16 Oct 2018, 21:52

I just finished changing the headgasket in my 2001 V40 and I went to time the engine and all went well, I manually put tension on the tensioner with and Allen head and then tightened down the bolt for the tensioner. Put the motor mount and serpentine belt on and started the car and heard a consistent clicking noise that was more like a smack! I turned it off and went to check and the arm for the tensioner was all the way forward and the belt was loose! Timing didn't skip or anything but it does this everytime. Hopefully someone can help me out who has seen this sorta thing before??

New tensioner or did you reuse the old one?
On the tensioner there is a pin that goes into the block .... is the pin broken?
If not are you placing the pin where it should be?

Got the whole lot so yes new tensioner. All installed right but when I adjusted the tension to take up slack I turned the Allen head clockwise and have just read I might need to turn it counter clockwise, it depends on the vehicle. Can you confirm this?

CCW on 4 and 5 cylinder, CW on 6 cylinder.

Part marked in Red fits into the block and the block keeps it from moving. If it not done right, it will move and the tension will be lost. The tensioner on the Volvo VDL Nedcars is different but the same principle.

You adjust the tension to temperature using the indicator and tighten the center bolt to 20 Nm (14.75124ft-lb).

See the attached file.

Thank you kindly, sirs! I will retry this later in the evening.

I spec'd the same vehicle using 2014D and looked at replacing cam seals and the procedure there is to turn it CCW to tension. They show similar illustrations and say to turn it to 10 o'clock for slacking to remove and show tensioned at 8 o'clock.

The T belt change uses the same procedure.

What Vida is the procedure copied from that was shown?

Damn weird. I have replaced several and turned them CCW on the 4's.

6's are different as CCW will put the allen wrench hole behind the balancer and makes getting the wrench out hard. CW on a 6 puts it at about 11 and that gets the hex hole out from behind balancer.

2014D AME 2001 V40. Search all for "timing belt", look for "timing belt replacement"

Same thing happened so I bought a new tensioner. Ill try again tonight and examine the one thats presumably shot and see what's going on with it!

The old tensioner seems fine and the new one does the same thing. I don't understand what's going on. After I have the timing set and the tensioner set I push down on the belt between both cam sprockets like it says to do and the tensioner goes all the way right and doesn't return.
