XF0747 69 Posted April 6, 2015 hey all as the topic says can you change the size of the power steering pulley or the pulley on the harmonic balancer? looking at putting a smaller pulley on either end as belts love spinning off @ 5000+rpm looking at one of these at the moment http://www.clarkosperformance.com/product_info.php?cPath=22_30&products_id=33 cheers for feedback guys Share this post Link to post Share on other sites
gerg 10,871 Posted April 7, 2015 Not aware of any off-the-shelf pump pulleys being smaller but harmonic pulleys are readily available and would solve your problem Seeing as the crankshaft is where your rpm measurement comes from, the pulley reduction should be from here. This will slow the belt down along with the pump pulley. The one you linked to is very small, would reduce power assistance a lot at low engine speeds. May not be liveable on an everyday basis.

XF0747 69 Posted April 7, 2015 the one listed is available in 2 sizes apparently car isn't a daily driver so not fazed about reduced power assistance at low speeds Share this post Link to post Share on other sites
gregaust 319 Posted April 7, 2015 Yeah have a look at some of the commodore pulleys are smaller diameter could be a goer Share this post Link to post Share on other sites

XF0747 69 Posted April 28, 2015 nah, its a prick of a thing to drive when it spins the belt off Share this post Link to post Share on other sites
dougie77 789 Posted April 28, 2015 Yeah but power steering with no assistance is different to manual steering Cortina for life Share this post Link to post Share on other sites
