How to check the front drive pulley lock nut
FYI: Torque Pulley nut to 100 lbs/ft (if dry) There has been discussion (based on sound fact from loctite's website) that any fastener utilizing Loctite (or anti-seize) should have the torque specification reduced by 15% of the dry torque spec. Many experts seem to agree with the basic reasoning but may vary slightly in the percent of reduction. Again use your one judgement

Some members have not only used Loctite, but also drilled and safety-wired the nut as well. - Reason: A few instances of the nut loosening again after retightening to proper torque and staking as per factory procedure have been reported here on the forum.

...and yet another RECENT example!
The nut size is Metric 30mm, but a 1 3/16 socket will also work. Please click on the 'Forum Post' link below for further details in the discussion about this issue.
Note also that the Nut and crush washer are supposed to be replaced anytime it is necessary to retorque the nut, according to factory procedure and the service manual. Several who've retorqued with Loctite and / or safety wire have reused the old nut and washer - they have in fact already deviated from the factory procedure with Loctite and Safety Wire, so Be advised that to do so is at your own judgement and risk.
This first pic is just for reference of the regulator/rectifier.
Here are the bolts that hold the cover on. Long shoulder bolts on the bottom.
Further detail of the regulator/rectifier.
Housing off and laying on a block of wood.
Make sure the nut is tight, then take a screwdriver or a punch and make sure the indents fit firmly in shaft "key ways".
