i got mine on ebay for about £200. brand new toyota one. otherwise i couldn't tell you if they are still available. As these engines are getting to 150k+ its def worth checking with routine maintenance. They are actually pretty simple to get off. there are 4 holes in the middle. two of the (opposites) are threaded. just thread in an appropriate size bolt. (about m8 i think) and just screw them in a couple turns each and it eventually pushes the pulley of. no special tools needed. I would run a tap in the threads first with some wd40 to make sure they are clean and easy to thread. i happened to snap a bolt in one of them. fortunately it was the old pulley off the new engine. I had put a new 200 pound pulley on the old engine... bet your ass i was transferring that over.
Booked in for MOT on tuesday so i prey that it goes through. I dont know how much more public transport my body can take. I dont wanna know how much i spent getting this car back on the road... I know i still got stuff to do to it as well. wanna get a few bits of rust sorted underneath during the summer so its solid and protected come winter, also wanna cleanup and replace the bushes for the front and rear subframe and running gear. again probably a summer job that i will start saving for now ready to do when its needed.
Will update the build thread at some point as i have fallen in love with he car again and got big plans.
