<div id="post_message_793374">I have a ZDZ80 which has 6 smaller bolts and a large nut on the main shaft for bolting on my prop. When I snug down the large nut, the 6 outer bolts get loose...so I tighten the 6 bolts, but then the big nut is loose again...so I tighten the 6 bolts. You get the picture...tightening one makes the other loose. What is the correct method for snugging down the nut and 6 bolts. When do I stop cranking on them?</div>
