I recently installed a BPS-1 sensor in an OS55HZ-R using silicon as instructed. After testing I wasn't happy with the % I was getting I decided to redo the whole thing. Well, that turned out to be a mission. I was probably a little heavy handed after getting mildly frustrated, and basically ended up with an unusable sensor. The problem was that the top triangular part comes away from the main body of the sensor and without anything to find a purchase on you end up having to extract the whole lot by pulling (as gently as possible!) on the small gauge sensor wiring. I'm thinking unless you're very careful and don't use too much silicon in the first place, installing a BPS-1 could be a one time deal. They might even have been designed as such, I don't know. Any thoughts?

Hi,

it is a "one way" sensor!
You can not removal. When you remove the sensor, you damaged the sensor.

Sorry....

Yeah I figured that was the case. I still think it can be done if you're careful though. I installed three at the same time and the last just wasn't right, otherwise i would have left it well alone.

There are some silicone dissolvers out there.

I wonder if one of those could be used.

Well, it looks like the BPS-1 crapped the bed in my 700N.

Engine started acting weird in flight today. Checked a few things, but when I got home and checked out the governor sensor, it was only reading 45% max. Even removing the glow plug so the starter could spin the motor faster yielded a max of 45% still.

It looks like the wire insulation got pulled back, and maybe some oil got in there and damaged the sensor.

Anyone else have this problem, or am I numero uno?

Guess I'll be finding out a way to get this thing out now, LOL!

Looks like Permatex makes a remover for their sealants:

I used the Permatex Clear RTV Silicone Adhesive that I'm sure most of you guys used to mount it, so I might see if I can find this stuff to remove it.

EDIT:

Then again, they're recommending this stuff for Silicone based materials:

Hmmm.
