With the Air Pump removed and the Greddy Pulleys installed, I picked up a Pineapple Racing Idler Pulley to fill in the gap. This pulley serves a simple but important purpose. Without the Air Pump in place, the leverage for the water pump pulley is reduced. The alternative is to compensate by over-tightening the belt, but this is a poor solution as slippage can still occur at higher RPMs. Secondly, you never want to over-tighten the belt because on top of reducing bearing life, it increases the stress on the crank pulley and by effect the eccentric shaft. <\/p>\n

When the Idler Pulley came in, I had to take a moment to survey the parts more closely. I almost immediately noticed the superb level of detail and quality. Apparently, after talking with Pineapple, the machinist that makes these parts has a long track record and was even contracted to make pieces for a lunar project. It takes one to know one, in my opinion; most people who don’t work with cars to this depth probably wouldn’t give more than a second glance… yet this kind of stuff brings out my inner geek. Just check out the consistency of the nickel finish!<\/p>\n

Installation was a straight forward bolt-on, but the space in its location was tight. In the end, everything went on just right.<\/p>\n

With the Idler Pulley in place, you can see just how much more belt surface area the water pump pulley is able to obtain (almost quadrupled).<\/p>\n

I adjusted the belt’s tension to have a deflection of approximately 3-5mm. Another good rule of thumb to go by: you should be able to grab a section of the belt in the middle and turn it a quarter-turn (until the ribs are facing you) without too much effort.<\/p>\n","protected":false},"excerpt":{"rendered":"
