Shafts come out every pass and both ends are checked for cracks, filed where prop tried to weld itself on, checked for straight, etc.
Props... cracked checked, checked to see how much the blades have moved, pitch changed, etc. They have a fixture they made to check stuff. I won't say any more than that. It is a piece of work. I learned more about props in 30 minutes than I learned in the last 10 years.
Got called for B team help the other night. The blower bolts sheared at the hit of the throttle. This caused 2 broken rods, welded on blower hub, etc. Lou said the hit of the throttle places so much load on the bolts it just sheared them. Reehl (SP) said the car guys stepped up to 7/16" blower and hub bolts.
Heads apart that got torched, etc. Now, here is the $$ part. They use H11 head studs. Some fancy material H11 material(duh). When it took out the heads it just put marks in the H11 studs. (I think 4 of them). They are junk now. Cost EACH $150.00. I'll quit bitching about BBC head stud costs now.
AND... here is where the questions come up... they had been using ARP lube on the H11 studs. They MUST use new nuts on the new studs due to close thread tolerance. They galled a nut on a NEW H11 stud $150. Anyway... they are trying a bolt lube caterpillar uses. Some of the cat stuff torques to 10,000 ft/lbs. I torqued nuts on hyd. cylinders that go to a mere 1200 ft/lbs.
Any idea what the cat p/n is? I think they are headed to Marble Falls alreadfy.
