I am sure this is a simple question. I installed new trim sensors on my Volvo DPS outdrives. Starboard is working fine but the port is not. When I turn the sensor by hand it works but once I put it in and attempt to adjust it doesn’t work at all… no movement. The old unit was pretty seized on there and I had to use a scribe to pull it out. Is the something that sits in that spot that spins the end of the sensor? Could that not be turning?
