Ok, next project.........................DANA TAB FAILURE
Dana Trim Tab Hyd failure. Port side hyd failure, cylinder leaks back up w/in 30 seconds. Thought about putting in a new pump but then thought it maybe the cylinder itself bleeding down. Not wanting to throw needless money at the tabs and was going to install mechanical tab indicators this winter, so that's out the window. Decided to retrofit with new LENCO XDS ball screw cylinders, along with the led position panel at the helm. Tabs are coming off this winter for powder coating so that's when the project will begin. I'll have to make a new billet transom mount as well as an adjustable position mount on the tabs for the new cylinders. I'll design the transom mount to cover all the existing holes from the HYD cylinder mount and try to reuse the Hyd line thru transom hole for the Lenco electrical cable. Don't want to drill any new holes if at all possible. |
Just an observation on the molded fiberglass platform. On many boats if you were to chop the throttle and let the boat settle into the water, you will have a wave hitting the stern and many times coming into the boat. I don't know if they designed it this way or they just got lucky, but when the wave comes from behind, it stays under the platform and splashes rearward out the little opening betweent he platform and the transom. That is nice because you never have to worry about a wave coming over the transom.

TRIM TAB RETRO FIT PROGRESS:
Here's what I'm starting with: http://i177.photobucket.com/albums/w...l.jpg~original Current base tab mount: http://i177.photobucket.com/albums/w...f.jpg~original New base tab mount: http://i177.photobucket.com/albums/w...t.jpg~original The upper mount will be replaced: http://i177.photobucket.com/albums/w...e.jpg~original Parts started to roll in today: http://i177.photobucket.com/albums/w...w.jpg~original More to come later as I make progress....................... |
Here's the tab LENCO cylinder brackets:
Progress today, before machine; http://i177.photobucket.com/albums/w...t.jpg~original After machining; http://i177.photobucket.com/albums/w...3.jpg~original The pair; http://i177.photobucket.com/albums/w...c.jpg~original |
Change of plans for the lower mounts shown above, decided to just reuse the old DANA TAB mounts and machine to fit my LENCO ACTUATORS.
Here's what I started with, DANA Series LT Hydraulic Tabs shown here and in prior postings: http://i177.photobucket.com/albums/w...l.jpg~original http://i177.photobucket.com/albums/w...e.jpg~original http://i177.photobucket.com/albums/w...f.jpg~original http://i177.photobucket.com/albums/w...f.jpg~original :mad::mad::mad::mad::mad: Who ever put these tabs on gets and "F" in rigging. You never, ever use 3M 5200 for something like this, let along butter the entire back side of the hinge plate with it. As you can see during removal pieces of the Gel Coat came off with the hinge plate even after applying heat to the hinge plate....................3M 5200 is for "LIFE" folks. So after some body work using Marine Tex as a filler, then re-gel'd the effected area, the project continued. http://i177.photobucket.com/albums/w...d.jpg~original So let the machining begin:[/B][/U] Top Dana Hyd Cyl Mount before cutting off Hyd fitting: http://i177.photobucket.com/albums/w...l.jpg~original http://i177.photobucket.com/albums/w...a.jpg~original Transom holes from the removed Dana Top Mount. Didn't want to drill any new holes, just reuse/cover old holes. http://i177.photobucket.com/albums/w...f.jpg~original Top Cylinder Mounting Adapter Plate and plate shown with water tight cable fitting: http://i177.photobucket.com/albums/w...v.jpg~original http://i177.photobucket.com/albums/w...h.jpg~original Top mount modified for LENCO ACTUATOR: http://i177.photobucket.com/albums/w...d.jpg~original http://i177.photobucket.com/albums/w...6.jpg~original http://i177.photobucket.com/albums/w...h.jpg~original Lower Tab Mount machined for LENCO ACTUATOR: http://i177.photobucket.com/albums/w...t.jpg~original All back from Powder Coating and mounted (dry fit before sealing it all up) http://i177.photobucket.com/albums/w...v.jpg~original Now it's onto the wiring of the digital indicator control at the helm.................... |
Very nicely done !

Good work. What did you use to reseal? 4200? Your right on the 5200, it will pull the gel all day long. Pulled a outer transom plate with 5200 on it. Was not pretty how the gel came with it.
