Thread: Air Compressor Rebuild ??

Front struts come with new voss connectors. I’m not sure about the valve blocks. You unscrew the voss connector on the old strut, then remove it and the collet so you just have the air line. On the new one you remove the blanking/dirt cover (white insert) then push in the air line up until the limit point (raised ridge).

Been working through giving the EAS a birthday. Replaced front struts and levelling valve that had white desiccant dust contamination. Had a major fail today trying to refurb the Hitachi compressor. I broke the top of the piston attempting to prise the ring seal retainer off. My better judgement said the instructional video on the kit suppliers website looked dodgy but I went ahead anyway. The vehicle will have to stay on the hoist till I work out a solution. I ordered a piston and cylinder kit from USA

Is there an easy way to determine which compressor i have on an MY08 D3 ?

I recently had my compressor fail - cylinder was stuffed. didnt realise that spare piston cylinder kits where available. Will have to order a set myself now and rebuild my old compressor for a spare.

That will suit a catastrophic failure but doesn't include the bits that most commonly fail like the dessicant, filters etc etc. It is rare that the actual piston and conrod fails - if it did you would be better just getting a new compressor.

For a rebuild you will most likely need these parts that are not included in the repair kit above.

Wow both kits add up towards $300.00 Aus approx plus postage could end up around the $400.00 plus with postage for a full kit is it really worth it .
What is a new compressor worth

And that doesnt include the motor so probably better off with a new one.
