last night, while playing in the shed :) I tried to put my fly wheel onto my engine.
I noticed that one of the bolts isnt threaded right up to the head of the bolt and thus when the bolt was torqued up it mushed the threads in the crank.
I know this is a factory bolt because its EXACTLY the same as the other bolts, except there is no thread on the very top of the bolt.
Also this bolt has a little red dot on the top, meaning someone somewhere at some stage marked this bolt as the one with the shoulder.
My question is:
Is this a factory thing? Is it normal to have a bolt that when torqued up, destroys the threads in the crank?
I wonder if perhaps this is some early form of locktight to stop the bolt coming loose? If it is then thats really annoying
Any help would be great :)
