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....

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.

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.

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.

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.
