aircraft engineer Posted February 21, 2008 Share Posted February 21, 2008 OK - it's a 10mm but what thread? Bolts out of the "standard puller kit" - 10x1.5 don't seem to fit (or at least I can't screw them into the holes in the damper). Thanks for the help in advance Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted February 21, 2008 Share Posted February 21, 2008 i gues you are talking about the harmonic balancer pulley on the crank. i couln't see or find any existing threads on the pulley, so i made my own. i don't know the size, but i guesstimated the size using a mounting bolt from the alt or power steering, went to the hardware store and bought several taps (non-metric) with different thread sizes. turns out i got it right on my first try. bolt size was a very close match and the puller i 'borrowed' from autozone had both thread sizes. kept the one i used and returned the other taps.

idosubaru Posted February 21, 2008 Share Posted February 21, 2008 most of the threads on these things are 1.25 pitch - so 10 x 1.25 is your animal. Quote Link to comment Share on other sites More sharing options...
aircraft engineer Posted February 21, 2008 Author Share Posted February 21, 2008 oh well - I guess it is NOT threaded. Use a 3 jaw puller? Quote Link to comment Share on other sites More sharing options...
Reveeen Posted February 21, 2008 Share Posted February 21, 2008 Mine comes off with a tap from a soft mallet, and twisting my mouth the right way. Quote Link to comment Share on other sites More sharing options...
lostinthe202 Posted February 21, 2008 Share Posted February 21, 2008 oh well - I guess it is NOT threaded. Use a 3 jaw puller? Mine took a bit of wigglin, but came off pretty easy by hand. Otherwise, yes a three jaw puller would do it provided you have enough room. I really shouldn't put up much of a fight. Will- edit - IT, it really shouldn't put up much of a fight! I would put up a fight:LOL: Quote Link to comment Share on other sites More sharing options...
subaru360 Posted February 22, 2008 Share Posted February 22, 2008 No way should you need a puller. The EJ dampers are not a press fit they just slide on. Quote Link to comment Share on other sites More sharing options...
msmithmmx Posted February 22, 2008 Share Posted February 22, 2008 Are you trying to remove the balancer? Hit it on both edges left and right side with a mallet. It should just slide off. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted February 22, 2008 Share Posted February 22, 2008 If it is hard to remove, the common issue is rust between the pulley and crank snout. Even a little bit of rust will make it hard to get off. On my '96 it was like this. I let some Kroil seep in there, and then kept tapping it with a plastic faced hammer and eventually she let loose.

Gloyale Posted February 22, 2008 Share Posted February 22, 2008 Otherwise, yes a three jaw puller would do it provided you have enough room. Don't use a 3 jaw. You could damage the edge and end up affecting the belt. It' not a press fit. should slide of by hand with enough wiggling and tapping.

Skip Posted February 22, 2008 Share Posted February 22, 2008 Some reports have surfaced of the damper being held on with locktite. This due to the crankshaft bolt coming loose problem . Gentle propane torch heat may help CAREFUL of the rubber isolation ring!! Quote Link to comment Share on other sites More sharing options...

It' not a press fit. should slide of by hand with enough wiggling and tapping. Assuming the puller is used properly, how does this damage the edge? I'm not contradicting, I've just never noticed anything in the past. thanks! Will- Quote Link to comment Share on other sites More sharing options...

I guess an EJ pulley could handle it, mostly because they should pull right off and not need tons of force. Quote Link to comment Share on other sites More sharing options...
Skip Posted February 23, 2008 Share Posted February 23, 2008 I have to agree with G If the pulley is "lockite"d on and a puller is used could the rubber isolation section of the damper be put at risk? The locktite mentioned here was in a post on the pulley coming loose and being put back on with the keyway a bit knackered. I agree will all who say it should not be that hard to get off as there is only about 0.500" of crank in the pulley hub. as seen here Quote Link to comment Share on other sites More sharing options...
lostinthe202 Posted February 23, 2008 Share Posted February 23, 2008 could the rubber isolation section of the damper be put at risk? I missed this part entirely when I had mine off, I don't remember there being any rubber on the thing. Granted, I didn't really scrutinize the thing other then to check the keyway for nicks. Is mine missing something that it should have? How's about a pic:popcorn: Thanks! Will- Quote Link to comment Share on other sites More sharing options...

'Prolly covered by grit/dust/whatever. So is it like an engine mount in that the pulley is two pieces that are bonded/captured by the rubber ring?

Skip Posted February 24, 2008 Share Posted February 24, 2008 seems I've spelled "seams" incorrectly? The pictured pulley is what happens when the bolt is not tight enough (incorrect torque given in FSM). The pulley slips, the keyway key machines the pulley, and well... it don't charge or have power steering afterwards. The key is pretty toast to, imagine that! For the life of me I can't figure out why only 0.500" proturde into the pulley. When the bolt gets loose the pulley wobbles and takes it's self out. Word has it the keyway and key only locate the pulley. It is kept from slipping mostly by the torque of the bolt causing the friction factor from the abutting surfaces. Thus coating these surfaces (shaft, back of the pulley, and the side's of the bolt's washer) with lockite provides some extra "locking". This could be what has the AE's pulley stuck on.

aircraft engineer Posted February 26, 2008 Author Share Posted February 26, 2008 just whacked it a few times with a rubber hammer and it came off. Should have tapped the holes in the pulley before I put it back on - but managed to torque the bolt to 75 anyway. Do a couple more of these and I'll be an "expert" Quote Link to comment Share on other sites More sharing options...
Skip Posted February 26, 2008 Share Posted February 26, 2008 keep torqueing at 75 ft-lb and you will be doing more as mentioned the tirque is wrong it should be 125 ft lbs please search the subject for verification. Quote Link to comment Share on other sites More sharing options...
