Tooseevee,
My 2006 AVL did not come with hardened washers under the head nuts in the rocker boxes too. The nuts outside of the boxes do. I have run it this way for 35,000 miles with no ill affects that I can see. Maybe they are not needed in there. The head nuts on my AVL have flanges on them. Can someone shed some light on if hardened washers are needed or not under the nuts in the rocker boxes on a AVL engine?
Royal Enfield people are good people
Cheers,
Bill
Ya know, that's very interesting. You're the first to mention it since I mentioned it. Why do you suppose the 2 inside the boxes are missing? Must be from the factory. I was the first to pull my head & now you say you found the same thing.
There are machined recesses for those 2 missing washers in the head, they are listed as Head Nut Washer (6) in the parts book & yet those 2 are not there. Do you suppose they just didn't want to fiddle around with getting them on the studs on the assembly line?
Did your flanged nuts fit into the recesses? Mine didn't. The circumference of the flange grabbed the shoulder & would not fit into the recess to hit the bottom flat. The washer is necessary to fill that recess.
Anyway. I found washers that fit the recess. I emoried both sides smooth & flat. I had to grind the hole just a hair to fit the stud.
