I bought a new one as I thought the old one wasnt very good. Just put the new one on, think I dont it how the manual says, let the bolt out that holds the tension in, and it never really pushed out. Thats why I bought a new one as the old one didnt do that. Do they not push out, only not stop pulling back in. Or dont they push as hard as I think they will?

bumpety bump...

Piston extension should be ~4mm which they are pretty much set to with the bolt. If you've set the tensioner correctly then it won't move much. Have you turned the engine over yet(clockwise)? This will pass any slack through the system and the tensioner will then probably push out a bit...

crunch time :p

LOL thats another reason you turn it by hand, so if you have got the belt set wrong you won't bend a valve (unless you force it round with a breaker bar :rofl: )

but youll have to disconnect everything on the engine then to turn it over!

 

mind u that will make tub changes that little bit easier.

I've turned the engine over and it all seems fine. The tensioner hasnt moved out anymore. Its just stayed at the setting when I pushed it on my hand. The movement of the belt where it says to check is within tolenrace.

Just seems like I wasted £175, lol.

The only thing that normally goes is the bearing in the roller and you can buy a new one of them for 20 quid.

I bought a new bearing for the other one when I changed the cam belt.

 

One thing I did notice with the old one was when you pulled on the belt, the plunger moved back in a little bit.

 

Spose it was worth buying a new one.

always worth replacing a timing part, cheaper than a set of replacment heads :(
