Hello, Healeyphiles -
Since the workshop manual does not specify a torque for the wire wheel rear
hub splined adapter nuts, this information might be helpful:
I just replaced the studs in the left rear wheel of my BJ8. I took the old
studs to the Materials Lab where I work, and they tested them for hardness.
The result was Rockwell C32 - C33, which corresponds to a Grade 8 bolt. The
standard torque tables for 7/16 - 20 Grade 8 Bolts gives 78 lb-ft (105.75
meeton-newters, for the metric crowd) as the recommended maximum torque. I
have torqued mine to 70 lb-ft.
Happy Healeying!
