zstalker Posted July 3, 2007 Share Posted July 3, 2007 the specification for the torque to be applied to the crankshaft pulley bolt on my '84 Brat is 39-42 ft/lb. does that seem quite low to anyone else? a ton of other engines have the spec above 100, and some even higher. do people really put the bolt at 42 ft/lb, and if so has anyone ever had a problem with the pulley walking off and wrecking the crankshaft? I'd feel much more comfortable above 60 ft/lb.... ~Erik~ Link to comment Share on other sites More sharing options...
Gloyale Posted July 3, 2007 Share Posted July 3, 2007 That seems fine to me. It is a hardened steel bolt and threads so going a bit tighter won't hurt, but it should't matter. 42 ft/lbs is pretty tight. Link to comment Share on other sites More sharing options...
nipper Posted July 3, 2007 Share Posted July 3, 2007 OLder roos dont make a lot of power, so its not an issue. On the 2.2 and 2.5 its a HUGE issue. I think my old VW beetle was like 25-30 ft/lb, but the axle nuts were 180ft lb. nipper Link to comment Share on other sites More sharing options...
Turbone Posted July 3, 2007 Share Posted July 3, 2007 Lock tight is your friend for that bolt. I got tired of mine backing out on the turbo models and finally started using it. No probs since. Link to comment Share on other sites More sharing options...
zyewdall Posted July 4, 2007 Share Posted July 4, 2007 has anyone ever had a problem with the pulley walking off and wrecking the crankshaft? Nope, it ruins the pulley when it comes off, not the crankshaft How do I know that you ask? Locktight, and make it as tight as you can get it, I say. It's steel, so you don't have to worry about stripping aluminum threads. Link to comment Share on other sites More sharing options...
