I'd loosen the crank bolt then marked the bolt, washer and pulley. It took three hard push to release. Each push produces a crack. Upon release I quickly tighten the bolt to 83-ft-lb, there is no snap or crack. Then release again but no crack. Then realizes that I should have mark the bolt before releasing.
Put oil on the threads and took less than a quarter turn to tighten from
7 ft-lb it to 83-ft-lb. Went for a drive. The marks didn't move. This isn't conclusive yet. The face of the bolt and washer show signs galling, a surface that has been rubbed by something else. SeeI might need to get a new washer and bolt just to see if the galling returns. A few years back I'd removed a 92 Accord, 92 Civic crank bolt, most likely their first timing belt change. No locktite. These bolt didn't produce a loud crack or galling as I'd expected. Here's more statistics on the subject car:
At 230k:
Bolt face galled: Yes Hard to remove: No; about 90 ft-lb, one swing, 3/4" ratchet - no ext. Color of threads: Grey from lube Thread degrease: Yes Threads oiled: Yes Reused bolts: Yes Bore threads cleaned: No Torque to: 83 ft-lb
At 280k, Yesterday:
Bolt face galled: Yes Hard to remove: Moderate; 98 ft-lb, took 3 swings, 3/4" ratchet - no ext. Color of threads: Grey from lube Thread degrease: Yes Threads oiled: Yes Reused bolt: Yes Bore threads cleaned: No Torque to: 83 ft-lb
If the bolt moves or gets tighter I'll post a follow-up - but don't know when.
