| Internal float switch on bilge pump failed, replacing with salvaged float switch from another pump. Installed Monday October 16. Need to add mild steel blank to prevent the pump floating off the sump sole and tipping with float disengaging before last few inches are pumped. |

October 2017
Compass drum mounting screw housing broken, drum mount twisted. Probably jammed in place due to drum tilt, resulting in spring stretched. Rebuild including fabricating new drum mount.
Upon further examination of the interior of the autohelm casing there is evidence of the spring rubbing against the casing near the compass drum, depositing scrapings from the casing on the spring.
The question is now did the drum mount failure cause the spring to scrape against the casing or did the spring jamb against the casing and cause the drum mount to fail?Longer wire cable and shorter spring? |
