Hey Guys,

Having problems with my Power steering belt jumping of once backing out of the throttle around 4-5000 rpm! I think its as a result of fitting a crank dampener pulley!

Fitted a pulley tensioner supplied by Abbey but its still jumping off, so looking for alternative suggestions please!?!

What are you doing?

hmm need more info what crank damper did you fit mate ?

 

[Steveline]

I think its ATI but i would need to pull out the Abbey invoice's.

2.8 RB Stroked Fardon/HKS crank, New N1 05U block, stock pump (64,000 miles) New Engine has covered less then 1500, relatively tentative miles!

Had the same isues when using a dogbox... Use a hks kevlar belt that streches less and up the tension on the belt to the upper limit as per manual

Check that the pulley is straight.

Check that the pulley is straight.

…Thanks…. How, is there a foolproof method for doing this?… …whilst fitted to the car!

Could someone confirm, an under size pulley would it under drive the pump, or over drive the pump, and what are the benefits?

I was thinking of trying a high sided pulley wheel, but there is no clearance between the stock wheel and the PS oil line, so a high sided pulley would touch the oil pipe, but if the pulley diameter was smaller than stock and the walls were the same size, this would achieve the same result (higher walls) right? But my logic says the pump spindle would be rotating faster!?!

Hi Guys, I still haven't found a solution to this problem. I did confirm that Abbey actually fitted a Ross pulley, not an ATI, as the Ross doesn't need to be re-built/serviced!

Can somebody who is running a high sided PS pulley let me know were they found it please?

Cheers,
Steve

This may sound condescending & obvious, but when tightening the belt, are you spinning the engine over even for a couple of seconds to allow the slack to accumulate? Then check again for free play, adjust again & do it as many times as it takes to get it consistently taut. You should be checking deflection at the largest span between two pulleys.

By all means don't over tighten it, but new belts stretch & require re-tightening.

ATI only needs a rebuild once every 10 years.

I just did my HKS ATI with new O ring kit and also swapped to an AEM trigger shell.
It was much easier than I expected.

I would really check the alignment

Mine jumps off at 8000rpm. Heard it was an issue with R32's. Alignment on mine has been checked. Would have thought ATI pulley would improve things though. That is my next upgrade.
