Is this the right Crank Bolt? (Pic)
Is this the right Crank Bolt? (Pic) OK, I got the stock bolt, then I went and bought another one longer in length, M16 2.0 thread pitch 130MM. I'm hoping I bought the right one that you all have been using.
Thanks, Philip S.

the washers are for reinstallation, which is the primary reason for the longer bolt.
the longer bolt lets you get more threads started when you are reinstalling the pulley which significant reduces the chance of cross threading or fubaring the crank threads. however the small head of the new bolt will go right through the pulley so you need large washers
basically i use like 2-3 large washers on the longer bolt to get the pulley on about 60-70% of the way, but then take the longer bolt out and use the old stock bolt on and finshed the installation normally

if you dont use a washer over the head of ur new bolt u are going to scrape ur crank balancer and dig into it... also should distribute the load across more surface area of the crank pully... not sure if that makes a big deal...
line up the threads on each bolt... if they sit in there really nice it is the same bolt thread.
