Got a new tensioner unit from Keron that I need to put on, the flexing bit has been refurbed but I need to swap the pulley wheel on mine as it has a better sleeve on it apparently ;)

 

So looking at it from this angle, which way do I need to take the bolt out? The assembly appears fixed so cant see if it goest against the flow of the belt and dont want to risk knackering it.

 

Cheers Guys :)

I have big problems now though, I managed to quickly and easily swap the wheel over and remove the old tensioner from the car and put together one good one. Everything was going well and I got it all in place and all that was left to do was to put the belt back on.

I got a breaker bar on the wheel (with the bar pointing to the left) and pulled it up to take some of the tension off to get the belt on, I presume this is the method others use? Again all going well until the last moment when the thread in the tensioner gave out rendering it useless.

 

Trying to put the old one back on and one of the 3 bolts that holds in place has had its head come off, wasn't putting much strain on it but maybe years of getting yanked by the tensioner have made it lose a bit of durability, so stuck trying to get an easy out or something to get that sorted now.

If anyone has any other solutions for relaxing the tensioner when it is back on please let me know :(.

Cheers to David2009 for phone help, I have put a bit of loctite on as recommended (my phones dead now anyway ;) )

The ideal angle to pull on the tensioner bolt head is from below (4-5 o'clock) but this is difficult re access. A 10"-12" ratchet that is horizontal (if you can go lower thats even better) and pointing towards the battery (but just short of it) and then pushing down, is the best compromise between access and not putting too more torque on the bolt.

 

You could always leave the bolt at a lower torque then you will naturally tighten it when you put move the tensioner/the belt on and can check and tighten further once the belts on if it needs it.
