Underdrive pulleys

A lift is helpful when installing the pulleys. You can do it with jack stands though. I had mine installed at a local shop and they used a lift.

I did mine with jack stands by myself (except my little brother held the brake while I broke the crank bolt free) without air tools. make sure you rent a pulley puller and its bolts fit the crank pulley before you start, unless you have acccess to another car to get the right thread bolts. Sometimes the pulley pullers come with standard bolts only, and we need metric. 8mm i think, but I'm not positive.

I removed the crank pulley from a SR20 and the puller I used, had 3 "arms" that grabbed the back of the pulley. I loosened the crank bolt, and put it back in a few threads, the puller arms grabbed the back of the pulley and the bolt fit the indention in the center of the crank bolt. This took like 5 min to do. I did have air tools, but the hardest part without them will be removing the crank bolt.

for the water pump pulley have some one under the car and you loosen the bolts then pry the engine with a crow bar just enough for your buddy to pull the old one out and then do the same to put the new one in from the bottom .pry to the block agains the chasis just enough to move the engine about 1/4 inch. worked great for me.the crank was easy just spray the bolts and pulley to let it come off easy.

Where can you get Underdrive pulleys, and how much do they cost? Are these 2 or 3 pulley systems(i've never really checked...)

www.importpartplus.com

That link doesn't work. Is it www.importpartsplus.com?

I didn't have to pry anything to remove and replace the water pump pulley. And I did everything from the top for the water pump pulley. That was for the B14 though. And I haven't looked at a B15 engine compartment.

b13 are tight around there.
