Help: I broke the Auto-tensioner!

[TalonJohn94]

I recently purchased an automatic hydraulic timing belt tensioner from KarKing.com.They have good service, communication and prompt shipping.

The problem is: the tensioner broke when we were trying to tighten/loosen tension to achieve .15 - .18 on the tensioner 'piston.' It broke right through the hole in the tensioner piston.

We did the timing belt per the VFAQ(s) and little reference in the Haynes manual.

Has anyone had this problem?
Do you think its just a defective part?
Do you think its an error on our part, during installation?

When you compressed it to put the holding pin in (eg. allen wrench), did you compress it VERY, VERY, VERY slowly (like steps of: 1/3 turn of vise handle, then wait 30 seconds for it to settle, repeat)? If not, you have damaged it's seals. Also you should only replace the auto tensioner with a factory one - no after market (or you will be regretting it).

^^AGREED!!^^^ I replaced my tensioner when doing my timing belt with an auto parts store brand, and when it failed my balance shaft hit the oil pump.

....When you compressed it to put the holding pin in.....

It was a new unit, with the pin in it when I got it (from KarKing) It broke when I was doing the procedure to get it within spec (around .15 - then wait 15 mins)

Then I got one from Renner Mitsubishi (Milwaukee, WI - DSM discount) for the same price (around $70) and it worked fine.

I'm hoping for my refund

Does anybody have a part number for the OE part?
