2001 135 optimax tilt trim problem

True grit

New member
Hi everyone. Not had any luck in the archive with this.

ive got a 2001 135. When the centre tilt ram closes and the motor lowers, the centre ram leaks oil from a telltale hole at the bottom of the ram. This is as the system pressure builds as it contacts the trim rods. It's like a pressure relief valve is lifting. I've stripped the ram, cleaned it, swapped out the internals from another ram, and no change. All seals and o rings seem fine. Plenty of oil, no corrosion etc. Can anyone please help?

Regards. Dale. UK
