Compressor Rebuild: replacing exhaust valve |
|
Hi all
After having had a new (used) Hitachi compressor fitted to my LR3, I would like to try and rebuild my old one to have on hand as a spare. I was informed that the old one had a fault with the exhaust valve which I subsequently learned was a relatively inexpensive part to replace, compared to the whole compressor.
Anyway, I’m having no luck removing the aluminium plug that holds the exhaust valve in place. I’ve tried various size sockets starting at 17mm, ratchet handle, impact gun, I even tried holding the head of the bolt in the vice and turn the compressor housing. Finally, when the soft alloy bolt head began to get destroyed from the abuse I tried jarring it loose with a hammer and punch. The still wouldn’t budge! It seems to be either held in with loctite or the alloys have ‘grown’ together?
The head is now starting to break up, and I know that it will shear off if I put any more force on it.
What’s the next step? Has anyone had success with drilling it out and tapping the thread? Other suggestions?

Spot on, thanks Garry. I dont suppose you can recall what size tap is required to tidy the threads up with once the plug was drilled out? 2016 LR4 SDV6 HSE

Sorry cannot help with that at the moment as I have not done mine as the superglue is sealing mine still. I am away from home at the moment so cannot measure the replacement cap thread.
Buy the kit with the cap and measure it.
Good luck
