Hydraulic tensioners.

A back yard mechanic was denied a warranty on a tensioner that failed because it had tool marks on the body where he had put it in the vice to push the pin back in after he had set the timing up incorrectly on his first attempt.

Fair enough or should he have gotten another one for free!

They are actually very simple to do, how "he" screwed up is beyond me.

It was the expensive one with the bearing atttached to it to.

And "he" is "he" and not "me"."Me" works in the parts shop.

Scuffing of the body is not going to damage the internals of the tensioner. The rate he compressed it at might though - they need to be retracted very slowly.

shoulda used a press, had to do it heaps on the engine in the wifes car

Oh.my apologies.

As crzyhrse said, they do need to be retracted slowly or it blows the hydraulics inside the tensioner. What is actually wrong with it! Doesn't hold tension! If it was something like the bearing noisy or an obvious manufacturers flaw I would replace it, otherwise tell him to buy a new one and maybe some instructions to go with it.

Yep.

Damn, maybe we missed out on an add on sale to a Haynes manual with that guy!
