frodo_monkey 0 Posted August 25, 2006 Hi all, I'm tearing a 1.6 engine apart to teach myself a bit about engine rebuilding... Having never done anything other than a headgasket before, I've done pretty well but have got stuck at the last minute! I just can't shift the 22mm crank pulley bolt ... The engine is out of the car, and basically everything else is off it - head, pistons, rods, flywheel etc. I did a quick search and found Russelltp's topic from May, and have tried wedging a hammer inside to stop the crank turning. I also tried an impact wrench on the bolt, as well as beating seven shades out of it with a big hammer. I'm thinking the next move should be a big breaker bar and finding a willing assistant to hold the block and wedge the crank, but has anyone got any better ideas? Frodo Also, what size in mm is the inside of the head of the sump plug? Can't find my sump plug tool or a ruler, so need to go and buy one without measuring...

sonofsam 5 Posted August 25, 2006 sump plug key is 8mm square jobbie. breaker bar should do it with a scoffold pole attached to it. All about the leverage my friend. You can also shock the bolt by giving it a few taps on the head Failing that a wee bit of heat or go down the gym. Share this post Link to post Share on other sites
Guest rick03054 Posted August 25, 2006 I'm thinking the next move should be a big breaker bar and finding a willing assistant to hold the block and wedge the crank, but has anyone got any better ideas? That's exactly what I did. It was on an engine stand so was easy enought o get someone to jam the ring gear with a chisel braced against the stand. I got a really long pole, put it over a breaker bar and put my weight on it. No probs Also, what size in mm is the inside of the head of the sump plug? Can't find my sump plug tool or a ruler, so need to go and buy one without measuring... If you take a handle off a door in you house you can use it and the square bar that connects it to the other handle to undo the sump plug. Why buy it when you can bodge it!

Believe it or not I actually tried that and unfortunately no, the metal (on the one I used anyway) was too soft and it just took the corners off the bar. I ended up using an allan key, 5/16 I think it was. Share this post Link to post Share on other sites
mickie 3 Posted August 25, 2006 i just wedged a big screw driver through the crank pulley and the block and got the bolt off with a breaker bar Share this post Link to post Share on other sites
Guest rick03054 Posted August 25, 2006 (edited) You can snap off the little bit that the timing dowel goes into, behind the pulley on the block, if you do that though. Which would make it more difficult to time up right to put the belt back on. Depends how much force you have to put into the bolt I suppose.

mickie 3 Posted August 26, 2006 (edited) i think its about 90lbs around there.. well thats how much force i had to use to get it off Edited August 26, 2006 by mickie Share this post Link to post Share on other sites
Guest rick03054 Posted August 26, 2006 To tighten it's around that figure. Although to be honest I was only thinking about loosening it. I've had one that came off really easily and one that nearly broke my back! You may have had a loose one so got away with locking the pulley with a screwdriver, I reckon if I did that with my tight one it would have caused some damage!
