Tilt/trim problem

[Capt dave 258]

Just picked up a 1992, 40hp Johnson with power trim. I had to remove the motor from the boat to get it home since I couldn't find the screw to release the pressure and manually lift it. I can here the motor when I press the up or down button, but it doesn't move. It appears to have been out of fluid and I filled it with trans fluid a few times and ran the button both up and down and it still doesn't move. I watched YouTube videos to try and find the release screw but no luck. On the very bottom of the piston housing are two Allen screws. One is much larger than the other. When I unscrewed the larger, it was under pressure and spit out the Trans fluid. The smaller Allen screw, I was unable to remove. Does anyone know where the release screw is on this unit? There is not a hole in the side of the mounting bracket that I can see, which is often the typical spot. Thanks for the help. See attached photos.

Found my release screw. See the above link. It was buried in the middle hole on the lower, port side and previous owner had it open. Too dark to work on it further tonight. Had to remove the long bolt that is threaded on each end and connects the pump to the frame. I was then able to lift the motor.

Sometimes you need to "help" the motor to trim up, by grabbing it and lifting. This will bleed them as well. Just let her sit a minute all the way up to allow air to bubble out of the fluid.

Usually, you fill them when tilted all the way up.
