Damage to timing belt tensioner

[drdouglas]

I'm working on doing a timing belt for the first time. While trying to get the tension right for the 4th time, I forgot to put the pin in the timing belt tensioner while releasing tension on the belt. I backed out the md998738, special tool slowly. In the process, it looked like the tensioner rod fully extended for about 15 seconds. I noticed it and tightned the rod back down. The last thing I want is damage to the tensioner making the belt jump. Is it damaged? It sounds like from the factory service manual I put a hurtin on it What do you guys think?

I would say that you're okey. The tensioner rod only comes out so far and stops. When you push it down with that tool and you definitely feel presssure as it goes down, you're okey.

I did that a few times as well with my belt job - let the tensioner rod come out all the way without putting back in the grenade pin and just pushed it back in with my tool.

you put some pressure on it but i think you did not damage it , are you sure it was only for 15 seconds ?

if you only put some pressure on it for a a few seconds i think you should be fine.

Actually it had no pressure on it at all. The hydraulic rod fully extended. I called a tech at Mitsubishi this morning and he said to get a new one. They said when it's released quickly, it can build up air bubbles in there and fail prematurely.

The cost of an auto tensioner is considerably less than the potential damage caused by it.

Listen to the tech and get a new one.

I did. Its on the way. It was a stupid mistake, but indeed another lesson learned.

ya man i did the same thing... If any fluid leaks out then it is garbage.. Sucks to waste 70 bucks on a tensioner... Better luck this time around...

70 bucks, man Mitsubishi gave the buddy discount for the great price of 90 bucks.
