Well, I had a day off work today so I thought I'd strip and clean my height sensors. 2 bolts each, what could be easier? ...

So, half a day later I have failed to get the first one off. The 2 bolts holding it came half out and then just span round and round. Closer examination reveals the plastic height-sensor has 2 brass collars (see photo) and the bolts seems to screw into the collars.

However, the collars just spin round and round. I tried using Q-bond to glue the brass collar to the plastic and failed miserably. I tried gripping the brass collars but there's almost nothing to grip and as soon as I put some force on the bolt the brass just broke away.

The only thing I can think of doing is to saw the ends off the bolts and then presumably drill the stubs out of the brass collars - or do the collars just bang out?

So, what I'm really hoping is that someone has a less destructive way of getting the bar-steward bolts out? Anyone?

While we're about it, how do you disconnect the arms from the sensor? I notice a little pin going through the join. Do I bang that pin out and then just slide the sensor off the arm?

Cheers,

I guess I could just fill in the gap with some split washers to stop it rattling!

Squeeze back on with pliers. I can guess how that would go with my luck!

You do not remove the arm from the sensor, new ones come with it fitted. You disconnect the arm from the suspension.
As Wammers has said repeatedly, you CANNOT service the sensors.
 
YOU CANNOT STRIP AND CLEAN SENSORS. How many times does it need saying.

Didn't catch your other post until I'd already posted this. Like I said, if only I'd spotted your post before I started!

I'm tempted to find a broken or cheapo one on eBay and have a play to see what it is like though. Just like to see inside things. :)

Probably a brass track with a spring loaded pole arm bit like a scalelectrick buttons nothing special:)

Think Keith posted a view of the inside of one a while ago.
