Gti6 Oil Pump Toothed Pulley Question.

[miamigtimark 3 1 Cars]

Just installed newly ground crank into the bottom end of the engine. All fittings put back in the correct sequence.

Should the toothed pulley spin freely on the crank once fitted?

Ive not fitted the oil pump yet and realise the spacer plate will take up slack but should the toothed pully be fixed somehow so it turns with the crank?

By toothed pulley do you mean the oil pump drive sprocket, or the cambelt toothed pulley.

 

The oil pump sprocket is secured by friction when it is all assembled and the main pulley bolt torqued up. (a horrible idea, most 1600 cranks have a keyway but 1900 don't).

 

The cambelt pulley is keyed to the crank.

Thanks Tom.

The engine is a gti6.

The oil pump drive sprocket is the one i mean.

I can spin it round the crank freely but ive not fitted the oil pump and spacer yet.

Seems a daft set up if the sprocket is driven on tension only.

I'm not a big fan of it but having said that it does the job on thousands of Peugeot engines out there. You just need to make double sure the main crank bolt is tight when you install it. I always use Loctite too.

Revised spec now, Buy a new drive wheel and it will be keyed which is what I always do now
