SHOWA trim tilt unit bebuild

[wavetamer]

was it hard to remove you trim end caps ??? did you make a tool or buy one

When I separated the pump assembly form the main unit there was three things that when into three of the five holes. the top hole had a hollow pin with a ball in it under that was 2 screens an o-ring and another piece, in the middle hole was some type of pin . I just talked to a guy at a local marina near my house and he thinks there is air still in the system . He said if I took the unit apart it could take a lot of bleeding the system to remove the air ??????? does that make sense ...

Thanks, Mike

Did the valve sub assembly (shown on diagram for 2001 150TXR) have a check ball inside of it? Did it fall out? Am I looking at the correct motor diagram?

Thanks rodbolt17 !
I could not find a diagram of the valve assembly or body to reference when putting her back together, was carful not to lose track of thing but who knows !! Any idea where to go for a detailed diagram of the SHOWA unit Yamaha used on the 2001 150hp ?


Thanks !

the down check valve or the pump assy.
something was not installed correctly.

I posted on the forum a couple weeks ago that I was going to attempt to rebuild the tilt trim unit on my 150 hp. Yamaha . I got some very helpful advise from members ! Thanks . Well my parts came in and I put everything back together, last night I added fluid to the trim cylinders before capping them and filled the reservoir . I followed the instructions shown in a you tube video on bleeding the system . After several fills and runs through the up and down range I still have an issue. When I raise the motor up and switch to lower it is stuck and won't go down , if I raise on the outboard manually while holding the down switch the motor lowers but is ****ing on the way down ! Goes up fine !! Anyone have this problem or got any suggestions ?

Thanks, Mike
