I have a strange noise coming from the subject unit on my Dory. So I am wanting to obtain a complete rebuilt unit. Then I can replace to noisy one and get it rebuilt. I've been looking all over the net but can't seem to find a rebuilt unit. New ones are fairly expensive, so I really would like to get hold of a rebuilt. Anyone able to point me to where I might find such a critter?

thanx,
 
I don't think that is the right motor because I did have it apart and the shaft is a bit different... it is squared off so as to fit into a slot maybe 3/8 inch wide. At any rate, I am not at all sure that the noise is coming from the motor. It may be coming from the cylinder somewhere... that is why I want to obtain an entire assembly. Then I can swap out and take the noisy assembly to a rebuild shop.

Here's the rest of the story... took Topkick out of winter storage... checked everything (but not the power tilt and trim... it always worked)... went to the lake and the PT&T didn't work on either engine. Seemed strange (double outage) so I started looking for a fuse. Noticed that the solenoids clicked so I decided it wasn't a fuse or a general electrical problem. Went back home. After further investigation, I noticed that the wiring right below each motor had been eaten by something... actually chewed up the insulation... spouse blames insects... I don't know. Anyway I surmise water then got into the motors and caused corrosion. So I removed the motor housing. The armature, brushes, etc were corroded. All were cleaned up and the port engine now tilts and trims like new. But the starboard makes a bad noise when raised. Lowering, it sounds normal. I noticed that there was a lot of cylinder oil in the bottom of the electrical motor when I was cleaning it. I think the seals may be shot. Even the port motor had cylinder oil in the bottom, although not as much as the starboard side.

Anyway, I think I can get these rebuilt, one at a time, if I obtain a rebuilt unit.

This also leads to another concern. I have always stored Topkick with the engines down. During this investigation, I learned that the cylinder is under pressure when the engines are down as you need the engines full up to top off the cylinder oil... unless you want to get an eye-full! So at least the cylinder oil fill is not under pressure with the engines full tilt up. Will the PT&T units store better up or down? Question comes from having seen the cylinder oil in the electrical motor housing.
 
k3lin-

Did you run the motors in both directions when they were out of the pump body and also check their continuity and resistance at the same time, before reinstalling them?

What type of pump moves the hydraulic oil? Are their vanes that couod have been damaged or warped? Are their solenoids or check valves involved? What kind of pressures are involved? Could high pressure boil any water in the oil on the high pressure side of of the pump (when raising the motor against a load), causing even higher back pressure and resistance? Just thinking out loud.....

Joe. :teeth :thup
 
WOW!!!

I don't have the answer to any of that stuff...

I didn't remove or dis-assemble the unit. I just removed three screws on the electric motor armature housing and lifted out the armature and brushes. I have no way of calculating all that other stuff.

Right now, I would just like to acquire a complete assembly and swap out.

thanx for all those additional headaches though... guess I needed them... I don't seem to get as deeply into stuff as you guys!... perhaps I should!!!
