hill_bill10 Posted January 28, 2011 Posted January 28, 2011 hi guys the inside pulley ( alternator ) on my engine is wobbling like mad when the engine is coldive checked that the nut is tight and it is so dont know wat it could be any ideas? Quote
james@cjperformance Posted January 28, 2011 Posted January 28, 2011 not too sure if this is correct but doesn't an alternator have a bearing in it?if it does it may be that it is work hence the wobbling, once warmed up it will expand and stop wobbling.again dont quote me on that Quote
hill_bill10 Posted January 28, 2011 Author Posted January 28, 2011 yeh they do i first thought maybe its that but if it was that why would the engine pulley wobble? Quote
james@cjperformance Posted January 28, 2011 Posted January 28, 2011 that pulley you have highlighted is the alternator pulley, if th bearing is gone it will wobble, or is it not that pulley that is wobbling? Quote
hill_bill10 Posted January 28, 2011 Author Posted January 28, 2011 yeh its that pulley, i just dont understand how if the bearing is in the alternator why that specific pulley wobbles and not one on the alternator? if that makes sense Quote
hill_bill10 Posted February 26, 2011 Author Posted February 26, 2011 hey guys, after much more investigation, ive found out its nothin to do with the alternator or bearing, the pulley itself has broken off the mount and is just wobbling around on it.any body else had this problem at all? Quote
cazzac2222 Posted February 26, 2011 Posted February 26, 2011 Ive never hear of this happening, the pulley you have circled above bolts on to the crank and aligned with a woodruf key, the only this i can think of is that the bolt has come loose and the pulley has come away from the woodruf key and the crank is spinning inside the pulley :S Im confused hahah Quote
hill_bill10 Posted February 26, 2011 Author Posted February 26, 2011 trust me that bolt isnt loose i was pullling and jumping on it all day today trying to get it off and it wasnt budging ill try get a video or sumthin of it doing it and let u see Quote
GT Phayer Posted February 26, 2011 Posted February 26, 2011 dont the crank pully have a damper in it ? Quote
enzo_e492901 Posted February 26, 2011 Posted February 26, 2011 dont the crank pully have a damper in it ?Yeah some of them.The larger pulley (the one at the back that drives the alt pulley) is separated/isolated from it's mounting flange by a rubber bush, It's a Harmonic Balancer Pulley. My guess is that the rubber is starting to come away from the mounting flange or the pulley. The smaller pulley is mounted directly to the other ones flange by 4 bolts on most of them. Some don't have Harmonic Balancers and the whole pulley is solid.I have seen this pulley wobble so much and for so long that it cut/ground it's self clean through the bottom cam belt cover. Don't let it get that bad, in theory the pulley could detach itself at any time. It will need replacing and they can be a little hard to get off.Gavin Quote
hill_bill10 Posted February 26, 2011 Author Posted February 26, 2011 thats sounds spot on enzo, it feels as tho there is a rubber bush , the pulley has come completely loose of this bush. im trying to find a replacement asap. Quote
enzo_e492901 Posted February 26, 2011 Posted February 26, 2011 From what I remember there about £160 new from Toyota so scrap yard/breaker/used is probably your best bet although you obviously can't be certen of it's condition or how long it might last.Gavin Quote
hill_bill10 Posted February 27, 2011 Author Posted February 27, 2011 ye, went to local scrappers today and they had none, hardly even had any toyotas in, was very dissapointed, theres a llightweight one on ebay atm for £75, so gonna ask around first if nothin comes think im gonna have to get that, atleast itll be nicen shiny if i do ;) Quote
Asad Posted February 27, 2011 Posted February 27, 2011 your probably best off going for the ebay one, not many around + most will be chipped anyway Quote
hill_bill10 Posted February 27, 2011 Author Posted February 27, 2011 http://cgi.ebay.co.uk/ALLOY-CRANK-PULLEY-C...=item45f8e73439thats it, worth it then? Quote
Asad Posted February 27, 2011 Posted February 27, 2011 That's the one would love a group buy on them Quote
Russleh Posted February 27, 2011 Posted February 27, 2011 does that not require power steering to be removed. it only has 2 belt spaces on it and you need 3 for the power steerin , water pump and alternator . Quote
enzo_e492901 Posted February 27, 2011 Posted February 27, 2011 does that not require power steering to be removed. it only has 2 belt spaces on it and you need 3 for the power steerin , water pump and alternator .The water pump and alternator are on the same belt.Gavin Quote
hill_bill10 Posted February 27, 2011 Author Posted February 27, 2011 the pump and alternator are on seperate belts on mine :S Quote
enzo_e492901 Posted February 27, 2011 Posted February 27, 2011 I don't know what pump you mean so just to confirm, I said Water Pump NOT Power Steering Pump. If you have water pump and alternator on seperate belts thats strange.Gavin Quote
hill_bill10 Posted February 28, 2011 Author Posted February 28, 2011 sorry my bad miss read what you were saying, yes power steering is on one belt and alternator is on the other, but its the pulley that they both go too that has broken the rubber seal has broken on the larger rear pulley ( the one the alternator goes tooo) Quote
hill_bill10 Posted March 17, 2011 Author Posted March 17, 2011 hey guys, meantto post these pics uo sooner but been busy, basically this is wat was wrong lol pretty much exactly how enzo described ithow its supposed to behow it wascheers for the help on this guys Quote
