Over the last couple of years I?ve noticed several posts from people (especially auto gearbox owners) wondering how to undo the crankshaft pulley bolt. It?s on very tight with a torque specification of between 159 and 174 foot pounds. Various options were suggested. Well here is another one. Don?t get me wrong. I?m not suggesting this is a better method just an alternative one. As you can see the set-up is quite simple. Put a socket (27mm or 1 1/16 inch SAE) on the head of the bolt then bolt the angle iron to the crankshaft pulley using two bolts (that then go into the two threaded holes which are there for pulley removal purposes). The end of the angle sits on the sway bar to stop it rotating. Next a socket extension bar is fed through the large hole into the socket and the bolt undone using a descent breaker bar. Advantage of this method is that you can set it up to undo the bolt and also use it to tighten up the bolt (159 ? 174 ft lbs) on assembly (picture is shown in assembly mode). I just used a scrap bit of angle that was lying around that already had the two attaching bolt holes drilled in about the right place (lucky me) so I only had to drill the 18mm one and I was set. My angle was 250mm long the large hole for the extension bar was 18mm diameter and 50mm from the end of the angle. The two attaching bolt holes were 8mm diameter and at about 70mm centres. The attaching bolts were 10mm head size and about 25 to 30mm long (preferably high tensile steel but mine weren?t). Not sure whether this would work for underdrive pulleys as I don?t know if they have the two pulley remover threaded holes in them. As I said, this is just another way of getting around a sometimes difficult problem. Cheerz.
