Marv 983 #1 Posted October 19, 2012 I am working on refurb of my B80. I plan to install a shock mounted engine on it like the C series with shock mounted engines. The frame will need to be drilled for the shock mount cradle. I need to determine the exact location of the holes to mount the cradle on lthe frame. Maybe someone has done this already and can provide the measurements. Thanks Marv Share this post Link to post Share on other sites
rmaynard 16,346 #2 Posted October 19, 2012 As long as you are doing a 1976 or 1977 B-80, find someone with a C-81 and get the measurements from that. 1974 and 1975 had the shorter frame. You will also need to get a different PTO set-up, belt cover and belt guides. Share this post Link to post Share on other sites
Marv 983 #3 Posted October 20, 2012 Bob, Mine is a 1977 model. Hadn't thought about the PTO and belt guard. What would be special about the PTO setup? Marv Share this post Link to post Share on other sites
rmaynard 16,346 #4 Posted October 20, 2012 The hoop that engages the PTO is shorter, and the bottom fits into the cradle. The original hoop was secured to the frame by a bracket attached to the frame. Share this post Link to post Share on other sites
