Crank bolt came loose yesterday and I could take it out by hand.....I have a d1sc w/ 6-rib. Can someone tell me the torque for the bolt or should I just impact it on.....

I am also looking into pinning the crank so if anyone has any pics or anything post em up.......thanks

A crank bolt coming out is VERY common, often people just put a lil loctite on it to keep it in place.

THe hub is what holds the dampener, you should pin it anyways so it doesnt have a chance to spin.

You will need a new crank bolt. This time around, get it pinned too.

Tq on the pulley bolt is massive. Use an old bolt to bed the pulley down at about 230 lbs/ft and then fit in a new bolt at 37 lbs/ft plus 180 degrees iirc. Before fitting the new bolt look for a 2-4 mm step appx between the pulley and crank snout.

That may not quite work. I believe the bolt in that kit is only to be used to hold the guide in place to drill/pin the crank. After the crank is drilled remove the bolt and the guide install the pin and new factory bolt....

I assumed the instruction would be followed

I know exactly what you mean. Mine did not come with instructions it looked just like that. Just wanted to make sure there was very little confusion...

As has been mentioned, use loctite on the new crank bolt. You will need to first clean the bolt threads of any shipping oils. Bob

I would save your money that bolt looks pretty pricey. And the factory bolts cost about 3 bucks and do a more than adequate job. I have read some posts about people having problems with aftermarket bolts. More than likey I would call most them operator error. We`re all gonna screw up stuff now and then. Preffer it not to be on the crank...The factory will work fine.. Good Luck to you.

Buy the pinning kit & an APR crank bolt & use a drop of locktite. I got all that from Bob at EPP & have never had an issue.....other than it taking me 2 hrs to drill the crank shaft.

I use the ARP bolt, no problems, I just use their lube on it no loctite. Nothing wrong with stockers, but I had mine on and off so many times the ARP made more sence. Very key to get the right torque on them, and get them pinned.

Absolutly key your crank.The first build up I did with the D1SC I did not key the crank.That is why i'm running a Iron block now.The pulley spun the crank nose and I had to build a new motor because of my ignorance! Cost$$$
