msmithmmx Posted October 7, 2007 Share Posted October 7, 2007 I decided to do it, remove the crank sprocket. Can someone tell me the easiest way to do this (95 2.2), It would really be helpful if I could see a pic of the tool that you have used to remove it or a model number. Also while trying to get a screwdriver behind the sprocket. I cracked off one of those little tabs that are on the backside of the crank. Should I now replace the sprocket? it does not look as if it does anything. It appears to little to help with balancing it, let me know...

avk Posted October 7, 2007 Share Posted October 7, 2007 I'm one of those who had this problem, but didn't take pictures. I posted a thread about this. In a few words, I was able to take the pulley off with a 3-jaw puller, actually assembled from three different ones, one Craftsman and two, large and small, lended by PepBoys. The arbor screw and hub were from Craftsman, others were too long to clear the AC condenser. The jaws were from the smaller PepBoys unit, whose claws were of the right shape, and the connecting links were from the larger one, the only ones with enough reach. Plus I had to hold the jaws on the pulley with a big screw-type hose clamp, and to place a suitable object into the hollow end of the crank for the forcing screw to sit against. Which tags (tabs?) did you break? The pulley is balanced by drilling holes. Hopefully you didn't break the timing sprocket. Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 7, 2007 Author Share Posted October 7, 2007 There is 6 or so of those tabs around the back rim of the pully, only one is busted off. Quote Link to comment Share on other sites More sharing options...
ron917 Posted October 7, 2007 Share Posted October 7, 2007 Those tabs are what the crank position sensor senses, so that the ECU knows where your crankshaft is in its rotation. Your car may not run well, if at all, with that tab missing. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 7, 2007 Share Posted October 7, 2007 Are you trying to remove the crank pulley, or the crank sprocket? The crank sprocket drives the timing belt; the crank pulley is the harmonic dampener which also drives the accessory drive belts. Either way, when either of those are hard to get off it is often corrosion between the crank snout and the pulley/sprocket. I apply good penetrating oil and try to let it get soaked back and down in there real good, this helps a lot. For the crank pulley, I had good results freeing it be tapping it with a deadblow hammer different ways/directions and it came off. For the crank sprocket, I kept gently prying behind it evenly on each side, using a strap wrench to nudge it clockwise, counterclockwise, etc, then when it started coming off and stopped, I applied more penetrating oil and tapped it all the way back on the snout, then repeated, getting a little further each time. If you cracked one of tangs off the crank sprocket, you will probably want to replace it, since that's what the crank position sensor on the oil pump 'reads'.

msmithmmx Posted October 8, 2007 Author Share Posted October 8, 2007 Lovely, looks like I will be replacing the sprocket due to a tab removal from a screwdriver. Not sure why I tried this... Thanks for the suggestions so far. Quote Link to comment Share on other sites More sharing options...
uniberp Posted October 8, 2007 Share Posted October 8, 2007 Lovely, looks like I will be replacing the sprocket due to a tab removal from a screwdriver. Not sure why I tried this... Thanks for the suggestions so far. I did the same thing, but I had to remove it because the woodruff key was broken inside and the fragment jammed the gear. It's a cheap, but time consuming fix. 8mm tap, a little bar of steel at leat .25 thick and 2 inches wide, 4-5inches long, a couple bolts and nuts. If you have never tapped a thread from blank before, GO slowly, and back out the tap each 1/4 turn to snap teh chip you just cut. You will feel a little resistance as you break of the chip. Maybe practice on the steel bar. Where you might get that IDK. DO NOT BREAK OFF THE TAP in the gear. It will take you an hour or so once you get all the stuff together, I did mine without removingthe radiator. Just put a piece of cqardboard behind it so ward off damage from errant wrenches.

msmithmmx Posted October 8, 2007 Author Share Posted October 8, 2007 Would there be any diference between a 2.2 and 2.5 crank sprocket? Quote Link to comment Share on other sites More sharing options...
uniberp Posted October 8, 2007 Share Posted October 8, 2007 Would there be any diference between a 2.2 and 2.5 crank sprocket? No. I have both. They are interchangeable. Check the part numbers online at 1stsubaruparts.com Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 8, 2007 Share Posted October 8, 2007 13021AA091 SPROCKET FOR CRANK PULLEY 1990-1996 ALL LEGACYS 2.2 goes behind Harmonic Balancer Lots of soobs use this same part # Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 8, 2007 Author Share Posted October 8, 2007 I called the dealer, they gave me 13085AA080. They all look the same, can they really be different? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 8, 2007 Share Posted October 8, 2007 Hm..did you look in the box yet? That part # for me comes up as "PULLEY IDLER (WITH TEETH)" for a number of soobs. That'd be the toothed timing belt idler near the water pump. Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted October 8, 2007 Author Share Posted October 8, 2007 The stealer-ship was wrong. You had the correct part. After seeing that the 2.2 and 2.5 are interchangeable I went ahead and found one on Ebay for 10 bucks. Thanks A lot for the help. I got the old one off with a screw drive and some PB Blaster.
