Put new belt and rollers on the car and for some reason the belt moved like this.
not sure why. Anyone have an idea?
Thanks.

Thom

You mounted the tensioner roller the wrong way around.

Paulyy

Yes I did. Fixed it.
It was the first thing I checked.

Thanks Thom.

easy to get the TB and BB tensioners mixed up on the 86 cars.

Whats the different with later cars?

For the odd reason mine has "late" features on the block like the ballance shaft housing & bearings. Sump. ect. But as far as i know it's the factory engine.
I also have the auto belt tensioner.

So what initially happened was the auto belt tensioner pulley broke and bang goes the engine.
When i got the new pulley, i wasn't sure which way it went on and it seemed right to put the all the same way. When i noticed the belt was out, i first went in the internet and looked at photos then checked mine and found the issue. PITA fix but all sorted now.

Stupidly i post my issue, then go looking for it and go back to the forum finding the same solution i've done.

Fixed now and so is the engine gladly.

82-86 TB tensioner is eccentric and looks like the balance belt tensioner but with the flange on the other side.

87+ "auto" tensioner is not eccentric, just a big gear with centered hole but with the same flange position as the early model

Paulyy

Ah i had thought you ment the gear/flange was different. gotcha.
Yeah well i have a spare eccentric gear because when i ordered the kit i asked for an 86'...
