Yet another NST crank pulley install...

[YarisSedan]

So first thoughts is you pretty much have to remove the lower bolt to the altenator. This like other memebers experience was increadibly hard. I would advise using a 6 point socket not a 12 point as you will round out the bolt. And a really large breaker bar. Even with that i had a huge amount of trouble breaking it loose. Then move the altenator slightly. Just to give slack on the belt. Do not remove the belt. Then simply zip off the pulley with your impact and zip it back on till it stops turning.

Whole process from start to finish took 7.5minutes. This was with help of air tools and a rack.

I took it for a test drive acceleration from a dead stop seems slightly improved. From a slight cruising to hard accel there is a slight improvement. I use the word slight because its not earthshattering improvement. Most people who will do this mod may not even notice any difference at all. I mean really most people wil lnot be able to feel the diference beween a few more HP. But it all adds up in the end. Just light weight reduction. 1 pound here 2 pounds there dosnt do much but at the end when your 100 pounds lighter then yeah before and after there is a diference. I will try to post some pics later when i get home.
