pulley coming loose
I have a 95 honda civic and the pulley that drives the alt,power steering
and A/C keeps loosening up.The bolt backs out I tighten it up and it is OK for a few days then it loosens up again.usuallythis bolt is so tight it is hard to get loose when replacing the timing belt.Has anyone seen or heard of this before? |

It sounds like you're referring to the front crank pulley bolt, correct? This bolt should be torqued to 137 ft. lbs. If you're not tightening it to this specification, then it could explain why it keeps coming loose. You could get it tightened at a shop or you could do it yourself. If you choose the latter, then you'll need the special crank pulley holding tool which is made by SP Tools part #60100. You can get this at Tool Town for about $50 if you have one nearby, or they can be purchased off the net for a little less. You'll have to search through this group via Google to get the URL. Eric |

One thought: if the key has been lost or sheared, then the pulley could turn in relation to the crank and gradually loosen the bolt. I would check out that possibility. If that's not the issue, you might use a little "Loc-Tite" on the threads....be sure to use the formulation that permits disassembly. Don't know the torque specs for that...I would guess 60-80 ft-lbs. |

Re: pulley coming loose
Never had a problem with them coming off, I usually use a torque wrench to
get it back to 137 lb-ft. As mentioned above, I would look to see if the key was missing. As long as it's torqued properly and the key is still there, it really shouldn't be loosening up at all. <null_pointer@nowhere.com.net.edu.gov.de> wrote in message news:nds510tvmnn9m9sva1q4gsh10jjcpflukb@4ax.com... > On Sat, 24 Jan 2004 16:24:00 -0500, "maxwell" <woods@horizonview.net> > wrote: > > >I have a 95 honda civic and the pulley that drives the alt,power steering > >and A/C keeps loosening up.The bolt backs out I tighten it up and it is OK > >for a few days then it loosens up again.usuallythis bolt is so tight it is > >hard to get loose when replacing the timing belt.Has anyone seen or heard of > >this before? > > > Hmmmmm.....done LOTS of these over the years and never had one loosen > up (usually use an impact gun to put 'em on).
