I was changing my HD pulley, wasnt that hard of a job, but a little time consuming and I got started late. Ended up putting the pulley on in the dark. Well, now I am definately paying for it. At first I heard this funny clicking noise and the next day noticed an oil leak (couldn't see it in the dark). Thought the pulley wasnt on all the way and that was why it was clicking and leaking. Impact wrench didn't help.
Now, today I pulled the timing chain cover, and to my horror, when I installed the HD pulley, it was slightly off, and pushed the woodruff key back, which got lodged sideways, and then when I started it up, the chain flung it into the cover making a hole (more noticible when I took it off and put it up to the sun) about the size of one of these smileys .
The oil slinger is also trashed, it scraped marks into the crank timing gear, and made a couple nicks in a few of the chain links.
I will post damage pics as soon as I can find my digital camera.
Just posted as a warning to anyone attempting this repair soon. DO NOT put the HD pulley on in the dark and MAKE ABSOLUTE SURE they are lined up correctly.
Now tomorrow morning I must go to a junkyard and get a new oil slinger and timing chain cover, and while I am in here I am going to replace both the timing chain and front main seal. I never want to see the inside of this cover again!
