2009 Bearacuda Maintenance
Objectives/Problems 1) In competition/practice we found the removing and attaching of the endcap both a lengthy and difficult process due to the small size of the fasteners (M3).
OBJECTIVE: To improve the endcap fastening method to take less time and be more ergonomic
SOLUTION: · Switch to M5 bolts o Easier to handle because of larger size o Hex head should be less prone to stripping because of larger surface area than hex slot in M3 screws · Switch to wing nuts o Reduce the number of tools needed to one (socket or wrench) o Help prevent stripping due to overtightening 2) In competition hull integrity check (pressure gauge on endcap) revealed a minor leak due to pitting of the flange and endcap surface from sand particles.
OBJECTIVE: To repair the sealing surfaces and modify the endcap fastening procedures to prevent further comprimises.
SOLUTION: · Re-surface flange and endcap surfaces to remove pitting · Cover sealing surfaces when not in use with clean cloths and blow sealing surfaces with compressed air before starting the sealing procedures.
Drawing Package Please see the 2009 bearacuda drawing package in the mece folder on the ARVP computer for details on the modifications and part numbers of new fasteners.
