dantd5 Posted February 6, 2016 Share Posted February 6, 2016 Hi Gurus and experts of the forum (bowing with head low ) I am about to change the compressor unit on my Discovery 2 2002 MY. My problem is the 2 bolts holding the unit to the chasis giving me a slight pain in the brain. I am tempted to cut it off but fear it will be another headache putting the whole unit back. The bolt rotates alright but never moves towards me. should I cut it? All comments accepted with open arms.

simonr Posted February 7, 2016 Share Posted February 7, 2016 Unfortunately, if the bolt is just turning, your options are very limited! Cut it then see if you can drill out the thread big enough that you can use a Riv-Nut in the chassis - which you can then screw the same size bolt back in to. Riv-nuts are one of my favourite inventions! If you have not come across them before, I believe there is some info in the Tech Archive ?on how to make your own insertion tool using just a Nut & Bolt. Proper insertion tools tend to be expensive. Si Quote Link to comment Share on other sites More sharing options...
dantd5 Posted February 9, 2016 Author Share Posted February 9, 2016 Hi Si Thanks for the advise. Many have told be to cut it out so I will just do that and yes will use a riv-nut. thanks once again. Dan Quote Link to comment Share on other sites More sharing options...
dave88sw Posted February 15, 2016 Share Posted February 15, 2016 the "nut" isn't in the chassis, its in a wing of the side of the plastic compressor housing and the chassis wraps around it. if you cut the bolt you should be able to prise the whole unit out and then the new housing will have a new nut installed. Otherwise, i have in the past left the old housing there and moved the innards of the new compressor assembly into it. Quote Link to comment Share on other sites More sharing options...
IanS Posted February 15, 2016 Share Posted February 15, 2016 Mine was like that and I successfully got the compressor unit out by undoing the 3 long bolts from the bottom and detaching the airlines. Putting it back was a bit tricky however...... Quote Link to comment Share on other sites More sharing options...
