Calling all engineers…I’ve got to pull & replace cutless bearings on a tug this spring. This project will be a first for me & the crew I’m dragging along to help. I’m in the middle of researching online and calling a few trusted cohorts about it & figured that this forum could be a good resource as well. Just looking for procedures & any tips that might make the job easier. We’re going to be working out of a remote location, my goal is to be as prepared as any newbie can be. I’ve replaced split flange and staves before, just not this type.
A few details.
- we still need to remove the props & shafts
- the bearings are Duramax flanged bearings, both the stern tube and strut. There are no screws to seat the bearings, I believe they are chockfasted in place.
- shaft is 4", the bearings are 16" long, OD of 5.25" @ about 35lbs apiece. This tug is triple screw, so I figure by the 6th one, we’ll be experts.
I’m interested in any and all thoughts in regard to procedures, tools…etc for removal, alignment & installation. I’m also looking for a Mate…(towing endorsement a must), but that’s for another day.
