Andy135 Posted April 10, 2021 Share Posted April 10, 2021 I've discovered why my port side trim tab actuator wasn't working. The motor is seized due to water ingress. See the puddle on the floor in the bottom right corner of the pic below? All that came out of the actuator when I opened it up. Luckily, despite looking crappy, the gears are all fine and turn the ram without excess friction or sticking, which means I can clean them up, relube them and re-use them. So I'll order a replacement motor and see how it goes from there. Quote Link to comment Share on other sites More sharing options...
Saintly Fish Posted April 10, 2021 Share Posted April 10, 2021 Looks like a good soaking in wd40 is in order there. I read somewhere that a motor from an electric drill will match up to that tab motor. Maybe you could look into that. Will probably save you a few quid if true!! No need to thank me😇 Quote Link to comment Share on other sites More sharing options...
suzook12 Posted April 10, 2021 Share Posted April 10, 2021 Can you get in at the motor? If so, it is repairable Quote Link to comment Share on other sites More sharing options...

Saintly Fish Posted April 11, 2021 Share Posted April 11, 2021 Andy, have you considered retro fitting the gyroscopic self levelling control to your system? I know when we chatted about it you were considering it if you replaced the whole system. It would take away a lot of extra thinking when at the helm in choppy conditions.

Yes, it will be repairable as long as the soft iron core hasn't evaporated.... I was quoted £100 for a rewind on a smallish motor albeit 3 phase. Yours may just need a wash off and fresh bearings which are pennies in comparison, someone such as simply bearings online should be able to supply what you need if you have the numbers or sizes.... And some fresh O rings and seal em up with vaseline or something. Seems you may have just found a new annual task, strip and replace O rings and reseal......

Andy135 Posted April 11, 2021 Author Share Posted April 11, 2021 Upper end of motor looks fine... But the lower end including the gear looks goosed. @suzook12, the gear looks to be a press fit. Any tips on removal before I go and buy a small puller? Quote Link to comment Share on other sites More sharing options...
suzook12 Posted April 11, 2021 Share Posted April 11, 2021 I would imagine it is, clean it up and look out for a locating pin. Wouldnt be surprised if all that needs is a bearing Quote Link to comment Share on other sites More sharing options...
Geoff Posted April 11, 2021 Share Posted April 11, 2021 (edited) That looks like a plastic gear and I would suggest that careful use of two correctly sized screw drivers at 180 degrees to each other would soon have it off. Get the shaft as clean as poss. before levering. Don't be to rough.good luck. Geoff.☺️ Edited April 11, 2021 by Geoff Andy135 1 Quote Link to comment Share on other sites More sharing options...
Geoff Posted April 11, 2021 Share Posted April 11, 2021 I posted at the same time as Zook. I suspect that there is not a pin, but if there is it should be easy to see it. there could be a flat on the shaft, but it doesn't look like it in the pics. Geoff.

Andy135 Posted April 11, 2021 Author Share Posted April 11, 2021 It's a metal gear. Doesn't look like brass, maybe some form of treated steel. Good idea about using two opposing screwdrivers. Quote Link to comment Share on other sites More sharing options...

Andy135 Posted April 11, 2021 Author Share Posted April 11, 2021 After soaking it in penetrating fluid whilst we went for a dog walk, the shaft now turns. Not smoothly, and as you say Steve it feels like it needs a new bearing. How do I take the motor apart? Looks like it's just held together by pressed tabs in the body casing.

Popular Post Andy135 Posted April 13, 2021 Author Popular Post Share Posted April 13, 2021 Bit of a win tonight. I've been leaving the motor standing upright and regularly dripped penetrating fluid around the shaft so it seeps down into the bearing. Just checked it this evening and I've found I can now spin the shaft easily. The shaft movement feels relatively smooth. So I rigged up a couple of leads and put the motor across a battery and it spun up perfectly. Looks like I may have a serviceable motor after all. mick, jonnyswamp, suzook12 and 2 others 5 Quote Link to comment Share on other sites More sharing options...

You really need to drip a 'sticky oil' into the bearing overnight, as WD40 (water repellent oil) and Plusgas (penetrating oil) will both dry out very quickly. Got any 3 in 1 or reel oil handy? , both will do the job fine Quote Link to comment Share on other sites More sharing options...
