Removed Hub Clamping Bolts and installed spinner rear bulkhead I/A/W Vans Section 44 Page 44-01 through 44-09. and Hartzell Propeller Owners Manual Number 115N 61-00-15 Revision 22 July 2016 Pages 3-11 - 3-18. The Vans drawings are actually for the RV-14 but all of the part numbers were identical and had alot more detail than the original RV-8 instructions and drawings. I called Vans and spoke with one of the technicians who indicated that they could be used.
