Hi
I repaired my suunto compass
the bellows had rotted away and all the fluid ran out.
It was relative easy and cost in total £5.00.
I think it was Nigel who had written a piece on a forum (not this one) a while ago and I am sure he will reply.
First take out the compass from the holding brackets. There is a black plastic bottom like a can which is pressed on to the housing of the compass. With the compass split and all the works taken out put the black plastic bottom half in to a pan off boiling water this helps to ease the push fit seal around the old bellows using a good flat screwdriver ease off all the way round. It?s quite tight to force off and you may have to keep immersing in the boiling water but keep going it will come, use a cloth to hold it as it?s hot (Health and safety covered).
Now to replace the bellows, down at the pound shop or on ebay you can buy a collapsible silicone cup with a lid you only need the lid, as this is silicon it is better than the plastic bellows that are factory fit and allow for the expansion of the fluid.
Fit the lid over the bottom of the compass up to the grove and force the black plastic bottom back on good idea to put the bottom back in the boiling water.
The filling hole is at the side you need a syringe like the type they fill printer cartridges with and 2 bottles 250ml JOHNSTON?S BABY OIL not the cheaper stuff.
Fill the compass back up only with the baby oil, it?s the last bit that is hard to get the last bubble out.
Mine was done 18 months ago and no problems crystal clear.
Good luck you have nothing to loose.
