Hello guys, I would be most grateful for your advice.
I'm just refitting the critical ESA (Engine Shock Absorber) nut PD7 and it doesn’t look to be far enough onto the shaft. I torqued it to 950 Lbs / Inch based upon recommendations I've seen for 75-80 Ft Lbs when using blue locktite.
I think I might know what's causing the problem but would appreciate your thoughts. I just took some close-up pictures and I think the reason why the nut isn't far enough along the shaft with 75-80 Ft Lbs torque and using blue locktite is because the nut/shaft appear to have been previously punch locked. I believe that the punches on the shaft or perhaps some resulting thread damage to the nut may be interfering with the torque settings and giving a false reading. Perhaps a new nut and cleaned-up shaft thread will fix the problem. I'm hesitant to keep on tightening, but it sure would be tight if I did!
Please note that I have the new and thicker PD5 spring plate (without the spring seats) fitted, but as you will see from the ‘before’ and ‘after’ pictures below, the nut seems like it should be much farther onto the shaft - so that the end of the shaft is close to level with the top of the nut.
Before the locktite set, I've now taken the nut off again and plan to order a new nut and washer but would appreciate any comments.
Thanks!
