Awhile ago I posted a thread about hearing a ticking sound when sailing and the engine was freewheeling. That sound became worse this season and obviously something needed to be done about it. Dana's engine is the original Yanmar 3QM30F with 6500 hours on it. First thing was to find someone who could work on the transmission. Rick Neari at East Coast Transmissions in South Amboy NJ assured me that the parts are available and he would be happy to do the job. Next job was to get the tranny off the boat and across to NJ. A good look at the possibility of removing the gearbox from the engine while in place assured me that there was no possibility! So the engine had to be moved into the main cabin to be able to do the work. Attached are some photos of the move and the engine sitting on the stbd bunk. The move is done by suspending two 2" galvanized pipes from the companionway and the hatch over the table. Two 1/2 ton chain falls are used to shuffle the 630 lb engine forward. It then is placed on a 4x4 cradle and it's ready for the work to begin. The KH-18 transmission comes off with 10 bolts and took 1/2 hour to do. One problem was that the rear engine mounts are mounted on the transmission housing and had to be removed and the engine resupported. Once the tranny came off the probable source of the ticking noise became evident, one of the five springs on the damper plate had broken free of it's holder and was loose. I'm hoping that is the solution but I'll have the tranny rebuilt as long as it is out. This Thursday the unit will travel to NJ for some TLC. I'll keep you up to date on the progress.
